According to Nasa, The Milky Way (Our galaxy) will crash into Andremoda and our galaxy will slowly wash away.
I'm not sure about you, but I think _I'M_ alive, and living in this galaxy. Since the NASA scientists probably think that THEY are alive, then they would not have confirmed that there is no life here. Life ELSEWHERE within this galaxy? The galaxy is too big, and our explorations of it too tenuous and new for us to confirm that there is no life on other planets even within the solar system. On other planets? It's anybody's guess, because we have no evidence either way.
NASA has launched the Kepler mission to search for new planets.
Most of the NASA planets fall in the world, although a few of them haven't, whereas relatively few non-NASA planets fall in the world.
Sorry to say but NASA is not a planet! NASA is an organization that studies the planets!
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. ---- According to NASA there are 9 planets in the Solar System, and the above are they.
The NASA rover operates in space, on planets other than the Earth.
Largest ones would be planets, although we cannot be sure if Jupiter still is. NASA still investigates if there is anything else by area bigger than a regular planet.
NASA does not research other galaxies because they are too far away to travel to in a lifetime.

As Pluto is no longer a planet - all of them.
