Interactive dark matter could explain Milky Way's missing satellite galaxies
Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.
Laniakea: Newly identified galactic supercluster is home to the Milky Way
Astronomers using the National Science Foundation's Green Bank Telescope (GBT)—among other telescopes—have determined that our own Milky Way galaxy is part of a newly identified ginormous supercluster ...
'Robo Brain' will teach robots everything from the Internet
Robo Brain – a large-scale computational system that learns from publicly available Internet resources – is currently downloading and processing about 1 billion images, 120,000 YouTube videos, and 100 ...
Review: Larger iPhones eliminate reason to switch
It's easy to dismiss Apple's new iPhones as merely catching up to Android.
Monster galaxies gain weight by eating smaller neighbors
Massive galaxies in the Universe have stopped making their own stars and are instead snacking on nearby galaxies, according to research by Australian scientists.
Smallest known galaxy with a supermassive black hole found
A University of Utah astronomer and his colleagues discovered that an ultracompact dwarf galaxy harbors a supermassive black hole – the smallest galaxy known to contain such a massive light-sucking object. ...
Pulse of a dead star powers intense gamma rays
(Phys.org) —Our Milky Way galaxy is littered with the still-sizzling remains of exploded stars.
Violent origins of disc galaxies probed by ALMA
For decades scientists have believed that galaxy mergers usually result in the formation of elliptical galaxies. Now, for the the first time, researchers using the Atacama Large Millimeter/sub-millimeter ...
Hubble paints a spattering of blue in irregular galaxy IC 559
(Phys.org) —Far beyond the stars in the constellation of Leo (The Lion) is irregular galaxy IC 559.
Gaia discovers its first supernova
(Phys.org) —While scanning the sky to measure the positions and movements of stars in our Galaxy, Gaia has discovered its first stellar explosion in another galaxy far, far away.
This star cluster is not what it seems
This new image from the VLT Survey Telescope in northern Chile shows a vast collection of stars, the globular cluster Messier 54. This cluster looks similar to many others but it has a secret. Messier 54 ...
Spitzer's SPLASH project dives deep for galaxies
(Phys.org) —A new survey of galaxies by NASA's Spitzer Space Telescope is taking a plunge into the deep and uncharted waters of our cosmos. In one of the longest surveys the telescope will have ever performed, ...
Image: Hubble sees spiral in Serpens
(Phys.org) —This new NASA/ESA Hubble Space Telescope image shows a beautiful spiral galaxy known as PGC 54493, located in the constellation of Serpens (The Serpent). This galaxy is part of a galaxy cluster ...
Variables of nature
Within physics there are certain physical quantities that play a central role. These are things such as the mass of an electron, or the speed of light, or the universal constant of gravity. We aren't sure ...
