The most distant galaxies astronomers have observed are seen as they were about 500 million years after the big bang, but galaxies are thought to have formed even earlier. Since light from these earliest galaxies has traveled through the expanding...

When it comes to the best region to form planets, it's all about location. Planets in the nearby star cluster Westerlund 2 may have a rough time forming in the crowded core. Astronomers using Hubble find that energy from hefty stars is blowing away...

Asteroids, many of which are locked in orbits between Mars and Jupiter, are the rocky leftovers of planet formation. The outer planets continually stirred them up, preventing them from combining to form larger bodies. But where did they originally...
