The Milky Way has a history of devouring its neighbors, the smaller satellite galaxies that orbit it. Over time our galaxy's gravity will tug on the near sides of these satellites more strongly than their far sides, slowly stretching them out. . .

Stars and planets are regarded as existing nicely within galaxies. We know that every now and again there are events that fling a star outside of the galaxy, doomed to wander the universe alone, but it was previously assumed to be relatively rare.

Astronomers have spotted a stunning burst of light as new stars are formed that beams out as much infrared light as an entire galaxy.The collision of two spiral galaxies has triggered this explosion, which is cloaked by dust that renders its stars nearly
Galaxy NGC 2683: Spiral Edge On

Michelle
- 2083 days ago - apod.nasa.gov
Does spiral galaxy NGC 2683 have a bar across its center? Being so nearly like our own barred Milky Way Galaxy, one might guess it has. Being so nearly edge-on, however, it is hard to tell.

Though they are the largest and most widely scattered objects in the universe, galaxies do go bump in the night. The Hubble Space Telescope has photographed many pairs of galaxies colliding. Like snowflakes, no two examples look exactly alike. This is one

There are billion of planets out there that much much older than our. Earth was estimated to be 4.5 billion years old. To find planets that are younger than our is possible, but there aren't so many planets that are younger than Earth. UK team just fou

These two mighty galaxies are pulling each other apart. Known as " The Mice" because they have such long tails, each spiral galaxy has likely already passed through the other. They will probably collide again and again until they coalesce.
