Provided by NASA At this time of year, there are lots of gatherings often decorated with festive lights. When galaxies get together, there is the chance of a spectacular light show as is the case with NGC 2207 and IC 2163 Located about 130...

New observations explain why Milky Way-like galaxies are so common in the Universe
Using a battery of observatories that included the ALMA and the Hubble Space Telescope, astronomers have obtained the best view to date of a collision between two galaxies that took place when the universe was just a fraction of its current age.
As astronomers have sought to understand the formation and evolution of galaxies, a handful of simple truths have emerged. Despite many questions remaining, we know that galaxies form in clusters, and create interlinked chains and structures that create a spider web across the cosmos.
Researchers at Iowa State University and IBM have identified why virtually all disk galaxies grow out of their irregular, clumped appearance, and why their older stars acquire the same smooth look as they fade from a bright center to a faint edge.
New research published in the Astrophysical Journal suggests black holes are growing at larger rates than what had previously been thought possible.
While searching for data looking for star-forming regions around a galaxy located more than 200 million light years away, researchers have accidentally discovered that it is, in fact, the largest known spiral galaxy in the entire universe.
A new Hubble Space Telescope image has been unveiled of NGC 922, revealing the cosmic structure to be an unusual spiral galaxy.
When massive galaxies belly-up to the interstellar buffet, their centers expand as they gobble up other galaxies that contain billions and billions of stars, according to a new report from University of Utah astronomers.
NASA astronomers announced on May 31 that they can now predict with certainty the next major cosmic event to affect our galaxy, sun, and solar system: the titanic collision of our Milky Way galaxy with the neighboring Andromeda galaxy.
A study of galaxies in the deepest far-infrared image of the sky, obtained by the Herschel Space Observatory, highlights the two contrasting ways that stars formed in galaxies up to 12 billion years ago.
Seyfert's Sextet -- Seyfert's Sextet is a group of galaxies in which gravitational forces are exerted between its members. The galaxies are so tightly packed together that gravitational forces are beginning to rip stars from them and distort their shapes. Those same gravitational forces eventually could bring the galaxies together to form one large galaxy. The name of this grouping, Seyfert's Sextet, implies that six galaxies are participating in the action. But only four galaxies are...
