Hubble captures stunning image of galaxies colliding

NASA's venerated Hubble Space Telescope has captured a striking image of the larger galaxy NGC 7714 colliding with its smaller companion NGC 7715. A similar cataclysmic collision is due to take place between our own galaxy – the Milky Way – and our closest neighbor, the Andromeda galaxy, in around four billion years. The image itself is a composite, comprised of a number of images captured by Hubble over a wide range of wavelengths. Read More

Hubble captures sharpest ever image of Andromeda

NASA has released a stunning panoramic mosaic of our closest galactic neighbor, the Andromeda Galaxy. The image was captured by NASA's flagship Hubble Space Telescope, and features an impressive 100 million stars spanning 40,000 light years. The image is comprised of 1.5 billion pixels and represents Hubble's largest mosaic to date.Read More

X-ray observations shed new light on dark matter

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

World's most powerful astronomical camera homes in on Andromeda

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

Swift snaps our best-ever ultraviolet image of neighboring Andromeda Galaxy

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
