New analyses of the x-ray and gamma-ray emissions from the center of the Milky Way galaxy, the Andromeda galaxy, and the Perseus galaxy cluster have detected significant signs of two possible dark matter particles. One is likely a 7.1 keV sterile neutrino, and the other appears to be a 35 GeV WIMP (Weakly Interacting Massive Particle).  Read More

When taking snapshots, a good telephoto lens can be handy, but when your subject is 2.5 million light years away, it’s invaluable. To show off the capabilities of the new Hyper-Suprime Cam (HSC) located on Mauna Kea, Hawaii, an international team of astrophysicists has released high resolution images of the Andromeda galaxy that not only show off incredible detail, but may help shed light on the evolution of the Universe and the distribution of dark matter.  Read More

The Andromeda galaxy is one of the most commonly studied objects in the sky. It's just 2.5 million light years from Earth, is visible to the naked eye on a moonless night and has been imaged countless times. Japan's Subaru Telescope's Hyper Suprime-Cam (HSC) has provided the latest snap of the popular object, showing our neighboring galaxy in a spectacular new light.  Read More

Pretty as a picture … this mosaic of M31 merges 330 individual images taken by the ultravi...

In a galaxy far, far away … about 2.5 million light years, in fact, lie approximately 20,000 hot, young stars and dense clusters that comprise the Andromeda Galaxy. The galaxy, known as M31 in the constellation Andromeda, was recently captured by an ultraviolet optical telescope aboard NASA’s Swift satellite, and delivers the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet.  Read More
