To (roughly) quote the Hitch Hiker's Guide to the Galaxy, every one of us is "an insignificant dot on an insignificant dot."1

Appears every 75-76 years, it's last appearance was in 1986. The next chance to see it will be in 2061.
If see this again, because I did see it in 1986, I will be 96 years old. Someone take me outside. Or hopefully I can walk outside. Or put me by a window, so I can look out please. Thank you.

M101: The Pinwheel Galaxy
One of my favourite galaxies! So pretty. I LOVE M101 and have so many pictures of it.
I think M88 might be my absolute favourite spiral galaxy though...

Ride the booster!
(The camera spins a LOT during much of this video... I suffer from motion sickness and was pretty much okay watching it, but be aware. )

Here is my gist - please enlighten me of my misinformationDoes this mean a lot of stars do not have planets?
The only “answers” I can find are on physics forums, (I never imagined myself perusing a physics forum, lol, but I was curious too )
the lay-gist I got was:
- apparently it is a very difficult question
- Stars are likely to have planets
- hard to say for certain, it’s difficult to prove that a star doesn’t have a planet
- don’t have the technology to say for certain – the stars' planets may not be detectable, (there are a few different reasons for this)MeeseeksAndDestroy wrote: »Good question...every star should have some planets right?
My lay-gist info says yes, in brief because of the way they both are formed
Are there any reasons a star wouldn't have planets?
- the star could have had a planet but something happened and it is no longer there (there are a few different reasons)
- possibly the stars close to the black hole at the center of the Milky Way Galaxy don’t have planets (anymore I'm guessing?) because of their proximity to the black hole (I’m guessing?)
- I also read something about how the first stars didn’t have planets ‘till later generations of stars had more metal elements in them, and then the stars could have planets
- I read a suggestion that a Blue Giant would make having a planet difficult or very hard to detect
Note: There are planets that don’t have stars - this is an easy to understand overview

The image was taken in green light with the Cassini spacecraft wide-angle camera on Jan. 18, 2017. The view was acquired at a distance of approximately 630,000 miles (1 million kilometers) from Saturn.
Although only a sliver of Saturn's sunlit face is visible in this view, the mighty gas giant planet still dominates the view. From this vantage point just beneath the ring plane, the dense B ring becomes dark and essentially opaque, letting almost no light pass through. But some light reflected by the planet passes through the less dense A ring, which appears above the B ring in this photo. The C ring, silhouetted just below the B ring, lets almost all of Saturn's reflected light pass right through it, as if it were barely there at all. The F ring appears as a bright arc in this image, which is visible against both the backdrop of Saturn and the dark sky. This view looks toward the unilluminated side of the rings from about 7 degrees below the ring plane.1 -

A Sneak Peek into Saheki Secret Layers (Mars)
This image from NASA's Mars Reconnaissance Orbiter is of Saheki Crater, about 84 kilometers across, and located in the Southern highlands of Mars, to the north of Hellas Planitia. It's filled with beautiful alluvial fans that formed when water (likely melting snow) carried fine material, such as sand, silt and mud, from the interior crater rim down to the bottom of the crater. Two smaller craters impacted into the alluvial fan surface in Saheki, excavating holes that allow us to see what the fans look like beneath the surface. Exposed along the crater's interior walls, we can see that the fan is made up of multiple individual layers (white and purple tones in the enhanced color image) that were deposited on the floor (the green and brown tones). The brown, circular shapes on the fan layers are small impact craters.
