Latest Interacting galaxy Stories
By observing colliding galaxies with the ESO’s Very Large Telescope (VLT) and the Hubble Space Telescope, astronomers have found evidence suggesting for the first time that dark matter may interact with other dark matter in a way other than through gravity.
Astronomers have long wondered exactly what fate befell the compact massive galaxies that could be found throughout the universe during its infancy, but new research from experts at the Swinburne University of Technology may have finally discovered the answer.
In four billion years, a mere blink of an eye by universal standards, planet Earth will be part of a galactic collision when our Milky Way will smash into the Andromeda spiral galaxy. Scientists got a preview of that event earlier this week.
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
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.
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...
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
- In medicine, cauterization.
