Astronomy: November 2017



There are hundreds of billions of stars in our own Milky Way galaxy.


Astronomers at The Australian National University (ANU) have created the most detailed radio image of nearby dwarf galaxy, the Small Magellanic Cloud, revealing secrets of how it formed and how it is likely to evolve.


A team of astronomers used data from both the NASA/ESA Hubble Space Telescope and ESA's Gaia satellite to directly measure the 3D motions of individual stars in a nearby galaxy.


There are too many high-energy positrons in the cosmic rays reaching the Earth.


Scientists searching for gravitational waves have confirmed yet another detection from their fruitful observing run earlier this year.


A new robotic camera with the ability to capture hundreds of thousands of stars and galaxies in a single shot has taken its first image of the sky -- an event astronomers refer to as "first light."


Astrophysicists from MSU (Russia) and his colleagues from Italy and Russian Academy of Sciences have found the first observational evidence for a contracting white dwarf.


New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) have uncovered the never-before-seen close encounter between two astoundingly bright and spectacularly massive galaxies in the early universe.


One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space.


Light from a supernova explosion in the nearby starburst galaxy M82 is reverberating off a huge dust cloud in interstellar space.


Supernovae, the explosions of stars, have been observed by the thousands. And in all cases, the transient astronomical events signaled the death of those stars.


A Chalmers-led team of astronomers has for the first time observed details on the surface of an aging star with the same mass as the Sun.


The ALMA Observatory in Chile has detected dust around the closest star to the Solar System, Proxima Centauri.
