THE MOON AND MARS: Mars is approaching Earth for a close encounter in March. Start looking for the Red Planet now:
Tonight it is shining brighter than a 1st-magnitude star beside the waning full Moon.
The view through a backyard telescope is dynamite: sky map.

About 9:30 PM EST I went out to see the moon and Mars and got a good look.  :)
I was able to view it on and off; cloud cover going back and forth.
It's a beautiful sight,

MARS AT OPPOSITION: Mars is approaching opposition. On March 3-5, the Red Planet will be up all night long, opposite the sun and as close to Earth as it will get in 2012. Mars shines overhead at midnight 6 times brighter than a 1st magnitude star and looks great through a backyard telescope.

"LOOK, THEN TURN AROUND: Just after sunset, as the evening sky fades to blue, Venus and Jupiter emerge from the twilight arrestingly close together in the western sky." [continues]
Turn around. Another planet, almost as bright and more beautifully colored can be found rising in the east. Mars is putting on a show of its own opposite Venus and Jupiter. The Red Planet is at its closest to Earth for all of 2012 on March 5th. It appears at sunset and soars overhead at midnight--an easy target for the naked eye and backyard telescopes alike

JUPITER-MOON CONJUNCTION--TONIGHT!
When the sun goes down tonight, step outside and look east. The Moon and Jupiter are shining through the twilight side by side. Most sky watchers will see the two bright bodies just a fraction of a degree apart. Observers in parts of South America will witness an even closer encounter--an occultation, in which the Moon passes directly in front of Jupiter.

Venus and Uranus will cross paths within 1.5 degrees of the sun on March 27-28. Mars and Venus have their own very close encounter on April 6-7. Mars will be so close to the sun throughout the month of April that it will limit NASA's contact with the Mars rovers and orbiters.

According to a NASA press release, "Mars will be passing almost directly behind the sun [as seen from Earth]. The sun can easily disrupt radio transmissions between the two planets during the near-alignment. To prevent an impaired command from reaching an orbiter or rover, mission controllers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., are preparing to suspend sending any commands to spacecraft at Mars for weeks in April. Transmissions from Mars to Earth will also be reduced." Mars will be at its closest to the sun, a slim 0.4 degrees on April 17th.

The ongoing dance of the sun and planets is invisible to the human eye, but coronagraphs can see the show. Join SOHO for a ringside seat.

April 2013 guide to the five visible planets

Only two of the five visible planets – Jupiter and Saturn – will be easy to spot in the April 2013 night sky as seen from around the globe. And how beautiful they are! Jupiter continues to be bright, as always, and Saturn’s best time of year is approaching. Meanwhile, if you live the Southern Hemisphere, however, you also have a good chance of catching Mercury in the predawn or dawn sky during the first few weeks of April 2013. Mercury, the solar system’s innermost planet, reached its greatest elongation of 28o west of the rising sun on March 31, so it’s still far west of the sun in early April. Unfortunately for temperate and Arctic latitudes in the Northern Hemisphere, Mercury is hard to catch because the narrow angle of the ecliptic submerges Mercury in the glare of morning twilight.

Mars and Venus will be especially difficult to see from anywhere worldwide in April 2013. Mars will pass behind the sun this month, whereas Venus recently swung behind the sun on March 28, 2013. The two planets are going in opposite directions, with Mars passing into the morning sky and Venus shifting over into the evening sky. The two shall meet up for a conjunction on April 6, though it’ll be lost in the glare of the setting sun.

Bright New Nova In Delphinus — You can See it Tonight With Binoculars

Bright New Nova In Delphinus — You can See it Tonight With Binoculars
by Bob King on August 14, 2013

Looking around for something new to see in your binoculars or telescope tonight? How about an object whose name literally means “new”. Japanese amateur astronomer Koichi Itagaki of Yamagata discovered an apparent nova or “new star” in the constellation Delphinus the Dolphin just today, August 14. He used a small 7-inch (.18-m) reflecting telescope and CCD camera to nab it. Let’s hope its mouthful of a temporary designation, PNVJ20233073+2046041, is soon changed to Nova Delphini 2013!

Several hours later it was confirmed as a new object shining at magnitude 6.8 just under the naked eye limit. This is bright especially considering that nothing was visible at the location down to a dim 13th magnitude only a day before discovery. How bright it will get is hard to know yet, but variable star observer Patrick Schmeer of Germany got his eyes on it this evening and estimated the new object at magnitude 6.0. That not only puts it within easy reach of all binoculars but right at the naked eye limit for observers under dark skies. Wow! Since it appears to have been discovered on day one of the outburst, my hunch is that it will brighten even further.

The only way to know is to go out for a look. I’ve prepared a couple charts you can use to help you find and follow our new guest. The charts show stars down to about 9th magnitude, the limit for 50mm binoculars under dark skies. The numbers on the chart are magnitudes (with decimals omitted, thus 80 = 8.0 magnitude) so you can approximate its brightness and follow the ups and downs of the star’s behavior in the coming nights.

Despite the name, a nova is not truly new but an explosion on a star otherwise too faint for anyone to have noticed.  A nova occurs in a close binary star system, where a small but extremely dense and massive (for its size) white dwarf  grabs hydrogen gas from its closely orbiting companion. After swirling about in a disk around the dwarf, it’s funneled down to the star’s 150,000 degree F surface where gravity compacts and heats the gas until it detonates like a bazillion thermonuclear bombs. Suddenly, a faint star that wasn’t on anyone’s radar vaults a dozen magnitudes to become a standout “new star”.

Novae can rise in brightness from 7 to 16 magnitudes, the equivalent of 50,000 to 100,000 times brighter than the sun, in just a few days. Meanwhile the gas they expel in the blast travels away from the binary at up to 2,000 miles per second. This one big boom! Unlike a supernova explosion, the star survives, perhaps to “go nova” again someday.

This map shows Delphinus and Sagitta, both of which are near the bright star Altair at the bottom of the Summer Triangle. You can star hop from the top of Delphinus to the star 29 Vulpeculae and from there to the nova.  Or you can point your binoculars midway between Eta Sagittae and 29 Vul. The “5.7 star” is magnitude 5.7. Stellarium

Update on the Bright Nova Delphini 2013; Plus a Gallery of Images from our Readers

by Nancy Atkinson on August 16, 2013

Since showing itself on August 14, 2013, a bright nova in the constellation Delphinus — now officially named Nova Delphini 2013 — has brightened even more. As of this writing, the nova is at magnitude 4.4 to 4.5, meaning that for the first time in years, there is a nova visible to the naked eye — if you have a dark enough sky. Even better, use binoculars or a telescope to see this “new star” in the sky.

The nova was discovered by Japanese amateur astronomer Koichi Itagak. When first spotted, it was at about magnitude 6, but has since brightened. Here’s the light curve of the nova from the AAVSO (American Association of Variable Star Observers) and they’ve also provided a binocular sequence chart, too.

How and where to see the new nova? Below is a great graphic showing exactly where to look in the sky. Additionally, we’ve got some great shots from Universe Today readers around the world who have managed to capture stunning shots of Nova Delpini 2013. You can see more graphics and more about the discovery of the nova on our original ‘breaking news’ article by Bob King.

If you aren’t able to see the nova for yourself, there are a few online observing options:

The Virtual Star Party team, led by UT’s publisher Fraser Cain, will try to get a view during the next VSP, at Sunday night on Google+ — usually at this time of year, about 10 pm EDT/0200 UTC on Monday mornings. If you’d like a notification for when it’s happening, make sure you subscribe to the Universe Today channel on YouTube.

The Virtual Telescope Project, based in Italy, will have an online observing session on August 19, 2013 at 20:00 UTC, and you can join astronomer Gianluca Masi at this link.

The Slooh online telescope had an observing session yesterday (which you can see here), and we’ll post an update if they plan any additional viewing sessions.

There’s no way to predict if the nova will remain bright for a few days more, and unfortunately the Moon is getting brighter and bigger in the sky (it will be full on August 20), so take the opportunity this weekend if you can to try and see the new nova.

Now, enjoy more images from Universe Today readers:

 SPACECRAFT GOES INTO LUNAR ORBIT:  Mission controllers flying NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft are among the select few at the space agency who have exemptions allowing them to work during the government shutdown. On the morning of Oct. 6th, they fired LADEE's main engine in a braking maneuver. This slowed the spacecraft enough for it to be captured by the Moon's gravity. The insertion burn went flawlessly and LADEE is now in lunar orbit. Two more main engine burns, on Oct. 9th and 12th, will adjust LADEE's trajectory, settling it into its commissioning orbit. LADEE is on a mission to study the exotic and diaphanous lunar atmosphere, which is mightily affected by space weather. 

 SUNSET PLANETS:  When the sun goes down tonight, step outside and look southwest. The crescent Moon and Venus are gathering for a wide but beautiful conjunction. Denis Crute sends this picture from Parkes, NSW, Australia:



"What a nice view just after sunset," says Crute."This picture is a 2 second exposure @ ISO 1600."

Tonight and tomorrow, the crescent Moon will pass by Venus, forming a bright duo visible long before the sky fades to black. Also, be alert for Earthshine--a ghostly glow illuminating the crescent's dark terrain. Earthshine is sunlight reflected from our own planet onto the Moon. A crescent Moon with Earthshine framed by twilight blue is one of the most beautiful sights in the heavens. Don't miss it! Sky maps: Oct. 7, Oct. 8. [ pages don't work for some reason.]

Possible New Moon Forming Around Saturn

April 14, 2014: NASA's Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn. Informally named "Peggy," the object may be a new moon. Details of the observations were published online today by the journal Icarus.

"We have not seen anything like this before," said Carl Murray of Queen Mary University of London, and the report's lead author. "We may be looking at the act of birth, where this object is just leaving the rings and heading off to be a moon in its own right."

PINK PLANET AT SUNSET: The Pink Planet is back. After an absence of more than 3 months, Mercury is emerging from the glare of the sun and making itself visible again in the evening sky. Giuseppe Petricca sends this picture taken last night in the Peligna Valley of central Italy.
"We had a wonderful sunset with beautiful twilight colors," says Petricca. "In the middle of my photographic session I remembered that Mercury would be visible, and indeed it was. It was the only bright dot shining through the twilight."

Mercury is mostly gray, not pink, but many observers perceive it as pink because of the surrounding rosy glow of sunset. Look west at sunset. What color do you see?

The view will improve in the evenings ahead. Mercury is heading for its best apparition of 2014 on May 25th when it willl be a full 23 degrees from the sun. Keep an eye on the sunset--and Mercury; it's a nice way to end the day.

This seems like as good a place as any to post this.

During the August 17 (or 21), 2017 total solar eclipse, visible in a band that will run diagonally across the United States from northwest, toward southeast, or vice versa, one should be able to see any cosmic or solar system objects/bodies in the apparent proximity to the sun, assuming the day is cloud free, and chemtrail free.

There will presumably be thousands of folks planning to make a trek to the penumbra for the opportunity to photograph the sun during its darkest hour, and also during which the adjacent "night sky" would show any entities in the same field of view, that may or may not be listed in the various star locator programs.

The first third of this film documents changes to Saturn's north pole as witnessed by the Cassini probe before it was demolished in September:

https://www.youtube.com/watch?v=BPrm0jfQPF0

A hexagonal pattern has appeared at Saturn's north pole which narrator says resembles several crop circles.  He notes that the number 144 appears on the crop circles in repeated geometric fractals.

Some of these hexagonal crop circles have a cube in the middle, which is an ancient symbol for the deity Saturn, believed to reside on the planet named for him. 

Interesting documentary of cube worship here: http://www.nicholson1968.com/cube-saturn-worship.html .  Another way to research it is to feed "black cube" into a Google image search and see what pops up.

Anyway, not sure what the changes to Saturn's north pole mean in relation to Px, or in relation to the recent decommissioning of the Cassini probe.  Any ideas? :)

Eight planets found orbiting distant star, NASA says

By Ashley Strickland, CNN
Updated 11:47 PM ET, Thu December 14, 2017

(CNN)For the first time, eight planets have been found orbiting a distant star, Kepler-90, 2,545 light-years from Earth in the Draco constellation, NASA announced Thursday. It is the first star known to support as many planets as are orbiting our own sun, and researchers believe that this is the first of many to come.

Researchers had known that seven planets were orbiting the star. But Google Artificial Intelligence -- which enables computers to "learn" -- looked at archival data obtained by NASA's planet-hunting Kepler telescope and uncovered the eighth planet.

With the idea of eventually differentiating among exoplanets, Christopher Shallue, senior software engineer at Google AI in California, and Andrew Vanderburg, astronomer and NASA Sagan postdoctoral fellow at the University of Texas, Austin, trained a computer how to differentiate between images of cats and dogs.

They refined their approach to identify exoplanets in Kepler data based on the change in light when a planet passed in front of its star. The neural network learned to identify these by using signals that had been vetted and confirmed in Kepler's planet catalog. Ninety-six percent of the time, it was accurate.
Since launching in 2009, Kepler has watched more than 150,000 stars in one part of the sky to determine exoplanet candidates, based on the slight dimming of stars as potential planets pass across them. Kepler gathered a dataset of 35,000 possible signals indicating planets. In order to help find weaker signals of potential planets that researchers had missed, the neural network was trained to look for weak signals in star systems that were known to support multiple planets.

"Machine learning really shines in situations where there is so much data that humans can't search it for themselves," Shallue said.
The new planet has been dubbed Kepler-90i. It's not a hospitable environment. It's small, "sizzling" hot and rocky, whirling around its star every 14.4 days. In our solar system, the closest planet to the sun, Mercury, has an orbit of 88 days.
"The Kepler-90 star system is like a mini version of our solar system. You have small planets inside and big planets outside, but everything is scrunched in much closer," Vanderburg said.
Although Kepler-90 is a sun-like star, the planets are all bunched together in tight orbits around it -- the same distance that Earth is from the sun.

"Just as we expected, there are exciting discoveries lurking in our archived Kepler data, waiting for the right tool or technology to unearth them," said Paul Hertz, director of NASA's Astrophysics Division in Washington."

Good article Barb.  Have you heard of a cigar-shaped object called "Oumuamau" which passed the earth on October 19?  There is some discussion as to whether it may be a natural object, or a spacecraft.  It's name is a Hawaiian word meaning "messenger from the distant past."

RR - I did hear about that. I had thought there were two stories that got separated out from it.. One a definite, named space object and another, unknown thing.  :)
I will have to take a look at this story, again...

First 'Trojan' Asteroid Companion of Uranus Found. Astronomers have discovered an unexpected, novel kind of triangle in the sky — one whose points are the sun, Uranus and a first Trojan asteroid ever seen near the tilted planet. The discovery is the first known "Trojan asteroid" for Uranus.

That's all new to me Barb.

Here's a definition of "Trojan" from the article:

Quote
To picture, say, Earth's Trojan asteroid, imagine the sun and Earth as being two points in a triangle whose sides are equal in length. The other point of such a triangle is known as a Trojan point, or a Lagrangian point, named after the mathematician who discovered them. At such a point, the gravitational attraction of the sun and Earth essentially balances out, meaning they are relatively stable points for asteroids or other objects.

Technically, the Lagrangian points do not provide stable parking spots for objects, because the slightest movement away from them puts the object in a position where the net gravitational attraction is no longer zero.  The spacecraft that are parked at Lagrangian points have to constantly apply small thrusts to move back into the zero-gravity spots.

R.R. thanks for posting this... wow what a strange object indeed, it has a really rapid rotation! Only a third the size of Earth. "THREE HAUMEAS COULD FIT SIDE BY SIDE IN EARTH."

"It takes 3.9 hours for Haumea to make a full rotation, which means it has by far the fastest spin, and thus shortest day, of any object in the solar system larger than 62 miles."

Haumea is a trans-Neptunian object; its orbit, in other words, is beyond that of the farthest ice giant in the solar system. Its discovery was reported to the International Astronomical Union in 2005, and its status as a dwarf planet—the fifth, after Ceres, Eris, Makemake, and Pluto—was made official three years later.

Oops!  Digging deeper, I discovered this:
" The unstable Lagrange points - labeled L1, L2 and L3 - lie along the line connecting the two large masses. The stable Lagrange points - labeled L4 and L5 - form the apex of two equilateral triangles that have the large masses at their vertices. L4 leads the orbit of earth and L5 follows "

Yowbarb Note-
This exoplanet, discovered in 2017 was mentioned in Suspicious0bservers video today. It is 900 light years away, probably Too far away to have anything to do with the PX system. Interesting though! This is the first time heavy metals were detected escaping from an exoplanet.

HUBBLE UNCOVERS A 'HEAVY METAL' EXOPLANET SHAPED LIKE A FOOTBALL
August 01, 2019 10:00AM (EDT) Release ID: 2019-19

HEAVY ELEMENTS DETECTED FOR FIRST TIME ESCAPING EXOPLANET
The scorching hot exoplanet WASP-121b represents a new twist on the phrase "heavy metal."

There are no loud electric guitar riffs, characteristic of heavy metal music, streaming into space. What is escaping the planet is iron and magnesium gas, dubbed heavy metals, because they are heavier than lightweight hydrogen and helium. The observations by the Hubble Space Telescope represent the first time heavy metal gas has been detected floating away from an exoplanet.

A scorching planet, WASP-121b orbits precariously close to a star that is even hotter than our Sun. The intense radiation heats the planet's upper atmosphere to a blazing 4,600 degrees Fahrenheit. Apparently, the lower atmosphere is still so hot that iron and magnesium remain in gaseous form and stream to the upper atmosphere, where they escape into space on the coattails of hydrogen and helium gas.

The sizzling planet is also so close to its star that it is on the cusp of being ripped apart by the star's intense pull. This hugging distance means that the planet is stretched into a football shape due to gravitational tidal forces.

How can a planet be "hotter than hot?" The answer is when heavy metals are detected escaping from the planet's atmosphere, instead of condensing into clouds.

Observations by NASA's Hubble Space Telescope reveal magnesium and iron gas streaming from the strange world outside our solar system known as WASP-121b. The observations represent the first time that so-called "heavy metals"—elements heavier than hydrogen and helium—have been spotted escaping from a hot Jupiter, a large, gaseous exoplanet very close to its star.

Normally, hot Jupiter-sized planets are still cool enough inside to condense heavier elements such as magnesium and iron into clouds.

But that's not the case with WASP-121b, which is orbiting so dangerously close to its star that its upper atmosphere reaches a blazing 4,600 degrees Fahrenheit. The WASP-121 system resides about 900 light-years from Earth.

"Heavy metals have been seen in other hot Jupiters before, but only in the lower atmosphere," explained lead researcher David Sing of the Johns Hopkins University in Baltimore, Maryland. "So you don't know if they are escaping or not. With WASP-121b, we see magnesium and iron gas so far away from the planet that they're not gravitationally bound."

Ultraviolet light from the host star, which is brighter and hotter than the Sun, heats the upper atmosphere and helps lead to its escape. In addition, the escaping magnesium and iron gas may contribute to the temperature spike, Sing said. "These metals will make the atmosphere more opaque in the ultraviolet, which could be contributing to the heating of the upper atmosphere," he explained.

The sizzling planet is so close to its star that it is on the cusp of being ripped apart by the star's gravity. This hugging distance means that the planet is football shaped due to gravitational tidal forces.

"We picked this planet because it is so extreme," Sing said. "We thought we had a chance of seeing heavier elements escaping. It's so hot and so favorable to observe, it's the best shot at finding the presence of heavy metals. We were mainly looking for magnesium, but there have been hints of iron in the atmospheres of other exoplanets. It was a surprise, though, to see it so clearly in the data and at such great altitudes so far away from the planet. The heavy metals are escaping partly because the planet is so big and puffy that its gravity is relatively weak. This is a planet being actively stripped of its atmosphere."

The researchers used the observatory's Space Telescope Imaging Spectrograph to search in ultraviolet light for the spectral signatures of magnesium and iron imprinted on starlight filtering through WASP-121b's atmosphere as the planet passed in front of, or transited, the face of its home star.

This exoplanet is also a perfect target for NASA's upcoming James Webb Space Telescope to search in infrared light for water and carbon dioxide, which can be detected at longer, redder wavelengths. The combination of Hubble and Webb observations would give astronomers a more complete inventory of the chemical elements that make up the planet's atmosphere.

The WASP-121b study is part of the Panchromatic Comparative Exoplanet Treasury (PanCET) survey, a Hubble program to look at 20 exoplanets, ranging in size from super-Earths (several times Earth's mass) to Jupiters (which are over 100 times Earth's mass), in the first large-scale ultraviolet, visible, and infrared comparative study of distant worlds.

The observations of WASP-121b add to the developing story of how planets lose their primordial atmospheres. When planets form, they gather an atmosphere containing gas from the disk in which the planet and star formed. These atmospheres consist mostly of the primordial, lighter-weight gases hydrogen and helium, the most plentiful elements in the universe. This atmosphere dissipates as a planet moves closer to its star.

"The hot Jupiters are mostly made of hydrogen, and Hubble is very sensitive to hydrogen, so we know these planets can lose the gas relatively easily," Sing said. "But in the case of WASP-121b, the hydrogen and helium gas is outflowing, almost like a river, and is dragging these metals with them. It's a very efficient mechanism for mass loss."

The results will appear online today in The Astronomical Journal.

The Hubble Space Telescope is a project of international cooperation between NASA and ESA (European Space Agency). NASA's Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy in Washington, D.C.

Dr. Peratt's comments from around the 42min mark should shake the foundation of cosmological physics. I have been assured that I have no liability for sharing these words and neither does he - we still aren't allowed to see the data or the models or visit the site or even know where in Nevada it was. Simply because you see fire and know its real, doesn't mean you can make it. Few people have ever been so privileged as the 0bservers are today, to be able to deliver such information as has never been heard before, in a manner that can be consumed by entire physics community.

Very interesting!  Has it always been so bright so as to cast a shadow?  It is easily visible in the evening sky here, but haven't checked for any shadows.  Maybe it's time.
