2018 LA, a 1.5-m-wide asteroid that disintegrated harmlessly over Botswana, Africa, just hours after its discovery on June 2, 2018, is only the second asteroid detected in space prior to impacting over land. According to new research, 2018 LA came from the inner main asteroid belt, where the large asteroid Vesta is found, and the impact that ejected 2018 LA in an orbit toward Earth occurred approximately 23 million years ago. Asteroid 2018 LA in space...

This image of the irregular dwarf galaxy Sextans B, taken by the Nicholas U. Mayall 4-m Telescope, features red-colored star-forming regions near the galaxy’s center; surrounding the galaxy are several bright stars that are located much closer to us in our Milky Way Galaxy, identified by the crisscross patterns created by light interacting with the structure of the telescope, as well as numerous fuzzy-looking background galaxies that appear small because they are much farther away than Sextans B.
