Hubble captures a formation of galaxies neatly lined up
A new Hubble image shows both an interacting galaxy system, and a string of galaxies which happen to line up in a neat procession......»»
Breakthrough Listen scans entire galaxies for signals from extremely advanced civilizations
In 1960, Dr. Frank Drake led the first Search for Extraterrestrial Intelligence (SETI) experiment at the National Radio Astronomy Observatory in Green Bank, West Virginia. In the more than sixty years that have since passed, astronomers have conducte.....»»
Unexpected chemistry reveals cosmic star factories" secrets
Two galaxies in the early universe, which contain extremely productive star factories, have been studied by a team of scientists led by Chalmers University of Technology in Sweden. Using powerful telescopes to split the galaxies' light into individua.....»»
New plasma instability sheds light on the nature of cosmic rays
Scientists from the Leibniz Institute for Astrophysics Potsdam (AIP) have discovered a new plasma instability that promises to revolutionize our understanding of the origin of cosmic rays and their dynamic impact on galaxies......»»
The Milky Way will probably devour all the tiny galaxies that surround it
The rapid disruption of smaller galaxies suggests they lack a bit of dark matter. Enlarge / An infrared image of one of the Milky Way's satellite galaxies. (credit: NASA/JPL-Caltech/STScI) We are not alone—at least as.....»»
Measuring the distances to galaxies with space telescopes
One of the James Webb Space Telescope's science goals is to understand how galaxies in the early universe formed and evolved into much larger galaxies like our own Milky Way. This goal requires that we identify samples of galaxies at different moment.....»»
Astronomers discover galaxies have bipolar gas outflows reaching far into intergalactic space
Astronomers have observed, for the first time in three dimensions, that gas from spiral galaxies is blown upward and downward at high velocity, far out of the galaxy. The observations confirm the prevailing theory of galaxy evolution that says that s.....»»
Black holes are missing in the early universe, and computers are after them
As far as the eye can see, galaxies fill the images of the deep universe. What processes determined their shapes, colors and populations of stars? Astronomers think that primordial black holes were the engines of galaxies' growth and transformation,.....»»
Top space telescope from Europe seeks to solve riddles of the universe
EU researchers expect unprecedented insights into galaxies from the study of a mysterious energy force......»»
Radio signals unveil secrets of massive galaxies
Black holes—the cosmic behemoths known for powering some of the brightest radio wave sources in the universe—were the focal point of a study led by Associate Professor Michael Brown, from the School of Physics and Astronomy at Monash University......»»
Astronomers spot giant stream of stars between galaxies
To their surprise, an international team of researchers has discovered a giant and extremely faint stream of stars between galaxies. While streams are already known in our own galaxy and in nearby galaxies, this is the first time that a stream runnin.....»»
Vera Rubin Observatory will find binary supermassive black holes: Here"s how
When galaxies merge, we expect them to produce binary black holes (BBHs.) BBHs orbit one another closely, and when they merge, they produce gravitational waves that have been detected by LIGO-Virgo. The upcoming Vera Rubin Observatory should be able.....»»
What would happen to Earth if a rogue star came too close?
Stars are gravitationally fastened to their galaxies and move in concert with their surroundings. But sometimes, something breaks the bond. If a star gets too close to a supermassive black hole, for example, the black hole can expel it out into space.....»»
Dark matter could help solve the final parsec problem of black holes
When galaxies collide, their supermassive black holes enter into a gravitational dance, gradually orbiting each other ever closer until eventually merging. We know they merge because we see the gravitational beasts that result, and we have detected t.....»»
A radically new view on dwarf galaxies surrounding the Milky Way
Commonly thought to be long-lived satellites of our galaxy, a new study now finds indications that most dwarf galaxies might, in fact, be destroyed soon after their entry into the Galactic halo......»»
Researchers describe a more sustainable process to recycle biobased polycarbonates
A month ago, the European Union banned glitter. This action was part of an effort that aims to reduce the presence of microplastics in our environment by 30%. Waste plastics are a serious problem for our ecosystems, and the push for recycling plastic.....»»
Dwarf galaxies use 10-million-year quiet period to churn out stars
If you look at massive galaxies teeming with stars, you might be forgiven for thinking they are star factories, churning out brilliant balls of gas. But actually, less evolved dwarf galaxies have bigger regions of star factories, with higher rates of.....»»
"Teenage galaxies" are unusually hot, glowing with unexpected elements
Similar to human teenagers, teenage galaxies are awkward, experience growth spurts and enjoy heavy metal—nickel, that is......»»
Physicists answer question of Supergalactic Plane"s absent spiral galaxies
Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our local universe called the Supergalactic Plane......»»
Redwood Materials will recycle Toyota"s spent hybrid batteries
Redwood Materials says Toyota deal marks the first time an automaker will use recycled battery materials from its cars in new vehicles......»»
