These stars should have pass us already. To escape the Andromeda galaxy they would have to move about 500 kilometers per second.
That would move these stars about 3.3 million kilometers lightyears in two billion years.

Indeed.
That's interesting!

Then if Andromeda is just a merger of smaller galaxies, than could our galaxy be the same? Our sun could be from another galaxy, technically.

I'm very saddened to hear about Hawking. He and Sagan were among my early sources of inspiration for thinking about physics and astronomy. And to think he came so close to seeing the first direct images of the objects that fascinated him.

Many say a new great will come about and they're probably right but you can never replace people like Sagan or Hawking. Their loss, while expected since we all die eventually, is a huge loss in regards to scientific understanding.

Juno snapped an infrared photo of Io.

Raw data is here (with images of Jupiter in infrared as well), with the portion at the bottom containing Io.

ESO created a 3D map and catalog of 1.7 billion stars in the Milky Way! Some sources say 1.1 billion, others (newer sources) say 1.3 billion of them have precise location and brightness. It would be pretty neat if SE could get a hold of their catalog, and add another billion stars to it

Yeah, it's pretty exciting, full of scientific implications too.
There's a special thread for GAIA mission for discussions and up-to-date news.

Holy Fissionable Banana Peels doc!
10 kilowatts in the bed of your truck! Enough to power 10 homes for 10 years!!

NASA announces successful test of lightweight fission reactor. A Uranium 235 core the size of a paper towel roll, using sodium to defuse the heat to electric power. Tested at full power for 28 straight hours.

4 of these could power a lunar outpost or an orbiter around any planet. Or my underground bunker. The possibilities are mind boggling.

12 new Jupiter moons discovered: https://www.theguardian.com/science/201 ... ng-jupiter

I have already made a script for the new moons.

Remember that interstellar asteroid ‘Oumuamua everyone was howling about? Well guess what - it is probably not an asteroid:

Or it is an alien spaceship. That just used his drive!

The line between an asteroid and a comet can be a bit hazy, anyway. But if it's very hazy, it's probably a comet.
