Textbooks often cite that planetary nebulae (PNe, plural) represent an endstate for lower-mass single stars. But conversely, recent research suggests that most PNe stem from binary systems. The lowest mass star theorized to form the typical PN is near 1 solar mass, and thus without a companion the Sun… Original post on phys.org Comments on reddit.com
The best map yet of light from the infant universe seems to rule out the strange motion of galaxy clusters, knocking down one sign of a multiverse Original post on newscientist.com Comments on reddit.com
Cluster bombs are impossible to use precisely, and the victims of such attacks describe them as collective punishment against populations that side with the rebels. Original post on nytimes.com Comments on reddit.com
(Phys.org)—Astronomers were puzzled earlier this year when NASA’s Hubble Space Telescope spotted an overabundance of dark matter in the heart of the merging galaxy cluster Abell 520. This observation was surprising because dark matter and galaxies should be anchored together, even during a collision… Original post on phys.org Comments on reddit.com
(Phys.org)—An international team of astrophysicists, including UQ’s Dr Holger Baumgardt, has shed light on the long-standing mystery of the binding force behind a cluster of unruly and rapidly swirling stars located in the famous Sword of Orion. Original post on phys.org Comments on reddit.com
NASA-funded astronomers have, for the first time, spotted planets orbiting sun-like stars in a crowded cluster of stars. Original post on nasa.gov Comments on reddit.com
Scientists have, for the first time, directly detected part of the invisible dark matter skeleton of the universe, where more than half of all matter is believed to reside. A filament of dark matter h Original post on umich.edu Comments on reddit.com
NASA’s Hubble Space Telescope has captured an image of two clusters full of massive stars that may be in the early stages of merging. Original post on sci-news.com Comments on reddit.com
A new form of very hard carbon clusters with a rather unusual structure is so hard it dented the diamond anvil used in its creation. The clusters are a mix of crystalline and disordered structures -… Original post on tgdaily.com Comments on reddit.com
Japanese astronomers using two radio telescopes have produced a map of carbon monoxide distribution in the central region of our Galaxy. While mapping the region, they identified three huge gas clumps and a number of intermediate-mass black hole candidates. Original post on sci-news.com Comments on reddit.com

Astronomers have spotted one of the rarest and most extreme galaxy clusters in the universe and, behind it, an object that shouldn’t exist. Original post on wired.com Comments on reddit.com
A massive galaxy cluster has been found 10 billion light-years away, making it the largest such object found at such a distance. Original post on space.com Comments on reddit.com
Japanese astronomers said Wednesday they had found a cluster of galaxies 12.72 billion light-years away from Earth, which they claim is the most distant cluster ever discovered. Original post on phys.org Comments on reddit.com
Spanning four continents and 50,000 cores, a cluster recently deployed on Amazon’s Elastic Compute Cloud saved cancer researchers from having to cut corners in an experiment. Original post on arstechnica.com Comments on reddit.com
Astronomers using data from NASA’s Hubble Telescope have observed what appears to be a clump of dark matter (image above) left behind from a wreck between massive clusters of galaxies. The result could challenge current theories about dark matter that… Original post on dailygalaxy.com Comments on digg.com
