Left-handed cosmic magnetic field could explain missing antimatter
The discovery of a 'left-handed' magnetic field that pervades the universe could help explain a long standing mystery – the absence of cosmic antimatter. A group of scientists, led by Prof Tanmay Vachaspati ...
Fresh evidence for how water reached Earth found in asteroid debris
Water delivery via asteroids or comets is likely taking place in many other planetary systems, just as it happened on Earth, new research strongly suggests.
The Pillars of Creation revealed in 3-D: Study suggests they more aptly named the Pillars of Destruction
Using the MUSE instrument on ESO's Very Large Telescope (VLT), astronomers have produced the first complete three-dimensional view of the famous Pillars of Creation in the Eagle Nebula, Messier 16. The new ...
Astrophyicists draw most comprehensive map of the universe
Astrophysicists have created a 3D map of the universe that spans nearly two billion light years and is the most complete picture of our cosmic neighbourhood to date.
Cold cosmic mystery solved: Largest known structure in the universe leaves its imprint on CMB radiation
In 2004, astronomers examining a map of the radiation leftover from the Big Bang (the cosmic microwave background, or CMB) discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. ...
Potential signs of 'interacting' dark matter suggest it is not completely dark after all
Astronomers believe they might have observed the first potential signs of dark matter interacting with a force other than gravity.
Astronomers solve decades-long mystery of the 'lonely old stars'
Many, perhaps most, stars in the Universe live their lives with companions by their sides – in so-called binary systems. Until recently, however, the ancient RR Lyrae stars appeared, for mysterious reasons, ...
Galactic 'hailstorm' in the early universe
Two teams of astronomers led by researchers at the University of Cambridge have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars - ...
NASA observatories take an unprecedented look into superstar Eta Carinae
Eta Carinae, the most luminous and massive stellar system within 10,000 light-years of Earth, is known for its surprising behavior, erupting twice in the 19th century for reasons scientists still don't understand. ...
Best of Last Week – New explanation for dark matter, a simulation of the universe and the randomness of cancer
Researchers find tidally distorted exoplanets may have unique signatures
Astronomers could soon be able to find rocky planets stretched out by the gravity of the stars they orbit, according to a group of researchers in the United States. The team, led by Prabal Saxena of George ...
Astronomers detect atomic hydrogen emission in galaxies at record breaking distances
(Phys.org)—Using the world's largest radio telescope, two astronomers from Swinburne University of Technology in Australia have detected the faint signal emitted by atomic hydrogen gas in galaxies three ...
Big black holes can block new stars
Massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, a study has found.
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.
