Re: APOD: Ou4: A Giant Squid in a Flying Bat (2020 Oct 07)

Talking about bats. Don't go too near the Bat Nebula, with its massive stars system. Or you have as Kathryn Janeway in a Star Trek Voyager episode to "batten down the hatches", when they come too close to a double neutron star system (https://www.youtube.com/watch?v=CeHtOxJMgDk).

Re: APOD: The Ghost of Jupiter's Halo (2019 Jul 11)

Art, if the galaxy has a diameter of, say, 70,000 light-years, and since you have the Ghost of Jupiter to compare it with, can you estimate how big it is in our skies and how far away it must be? The bright part of NGC 3242 is about 7,000 times as far away as it is wide. Your galaxy is about 14,000...

With such a pack of black holes, there should exist hyper-velocity black holes thrown out of the center by the massive Sgr A*. With perhaps a lot of luck one should even find a hypervelocity binary including a black hole. Or have researchers already found one? Just as research show it is possible fo...

It's not unusual that a star or a star cluster passes by a dark, dusty nebula. The Pleiades https://apod.nasa.gov/apod/ap171114.html is doing it too.

The comparison you make, with two other of Saturn's moons is very interesting: Atlas and Iapetus. I am also looking forward to better images of Atlas. Perhaps the Cassini team will deliver something in the future.

A wonderful image.

Also a slightly illusory picture as the ship in the front is pointing left, toward the big ship on the sky: the constellation Argo Navis with Canopus. Nowadays you don't talk about Argo Navis as it is so big and one instead speak about the constellations Carina, Vela and Puppis.
