Urvara and Yalode: Giant Craters on Ceres
This image from NASA's Dawn spacecraft shows the large craters Urvara (top) and Yalode (bottom) on dwarf planet Ceres. These features are so big that they must be observed from high altitudes in order to fit in the frame of a single image. Urvara is (101 miles (163 kilometers) in diameter, while Yalode is 162 miles (260 kilometers) in diameter.
The two giant craters were formed at different times. Yalode is almost 1 billion years older than Urvara, which is about 120 million to 140 million years old. Yalode's relatively smooth floor indicates Ceres' crust material became close to -- or even reached -- the melting temperature of ice as a consequence of the heat generated by the impact. On the other hand, the smaller Urvara has rougher terrain.
This suggests Urvara had either a lower temperature increase from the impact, or a colder crust temperature at the time of the crater's formation, or a combination of the two. Indeed, Ceres' interior was warmer in the past, and has been slowly cooling as its supply of radioactive isotopes, whose decay represents Ceres' main heat source, has been decreasing over time.
This picture also reveals geological details such, as the feature Nar Sulcus inside Yalode and a central peak in Urvara. Urvara is named after the Indian and Iranian deity of plants and fields. Yalode is named for the Dahomey goddess, worshipped by women at the harvest rites.
This image was obtained by NASA's Dawn spacecraft on June 9, 2015. The spacecraft was then in its survey orbit (2,700 miles, 4,400 kilometers above the surface), when the footprint of Dawn's framing camera on Ceres' surface was about 260 miles (420 kilometers) across on Ceres' surface.
The resolution is 1,400 feet (410 meters) per pixel. The central coordinates of the picture are 43 degrees south latitude, 278 degrees east in longitude.1 -

A cold celestial dwarf. According the International Astronomical Union a planet and a dwarf planet are not the same category
I know, so it's in between then if it's not a dwarf planet nor a regular planet. Is it a PLU-net?0 -

Lol no it is a dwarf planet
Reading compression is hard. I kept reading the red lines as it's not a dwarf planet. I was like, that doesn't make sense but it's got to be true since @MeeseeksAndDestroy wouldn't lie about science.1 -

Edge-on Galaxy
NASA Hubble Space Telescope has imaged an unusual edge-on galaxy, revealing remarkable details of its warped dusty disc and showing how colliding galaxies trigger the birth of new stars.2 -
TIL the Challenger crew, most if not all, were probably alive until impact with the ocean. A lead NASA investigator said of the commanding pilot, "Scob fought for any and every edge to survive. He flew that ship without wings all the way down."

Through the brilliance of Saturn’s rings, Cassini caught a glimpse of the far-away planet Earth and its moon. At a distance of just under 900 million miles, Earth shines bright among the many stars in the sky, distinguished by its bluish tint.

So the question is what side of the planet is in this picture? Basically I want to know if this is a selfie of North America or not.
This is only the third time ever that Earth has been imaged from the outer solar system.
In this rare image taken on July 19, 2013, the wide-angle camera on NASA's Cassini spacecraft has captured Saturn's rings and our planet Earth and its moon in the same frame. It is only one footprint in a mosaic of 33 footprints covering the entire Saturn ring system (including Saturn itself). At each footprint, images were taken in different spectral filters for a total of 323 images: some were taken for scientific purposes and some to produce a natural color mosaic. This is the only wide-angle footprint that has the Earth-moon system in it.
The time for the cosmic smile toward Saturn will be a 15-minute interval that begins at 5:27 p.m. EDT, 4:27 CDT, 3:27 MDT, 2:27 p.m. PDT (21:27 UTC). Beginning then, and for 15 minutes, the light reflected by your smile and wave will make the journey from Earth to Saturnian orbit – a journey of nearly 1 billion miles – in time to be captured by Cassini’s camera about 80 minutes later.

From New York City, Saturn will be low on the eastern horizon from 5:27 to 5:42 p.m. EDT on July 19, 2013. Saturn’s approximate location is shown, but it will not be not visible in the daylight. Image via NASA.
It is a selfie of North America!

I looked it up myself so I could quote it. But yes you got the info first. But what I want to know now is if the simulators out there say the same thing for that time and date.

2018's 2nd Blue Moon on March 31
Yet it’s indeed quite rare to have two Blue Moons in a single calendar year. It last happened in 1999 and won’t happen again until 2037.

I don't think I can run Universe sandbox at work so I'll check when I get home
You can do anything you want if you try hard enough. I believe in you.

Check out In The Sky to see whats visible in the sky from your current location.

I used it to confirm again that Saturn was in the skyline for my location at 5:27 to 5:42 p.m. EDT on July 19, 2013.1 -

That's really cool. Too bad everyone in North America didn't know so we could have waved during the selfie.1 -

NASA did tell people ahead of time but for what it's worth I didn't know at the time
I don't remember hearing it. Bummer.
