An international team of astronomers led by the Max Planck Institute for Astronomy (MPIA) has made a surprising discovery about the birthplace of groups of stars located in the halo of our Milky Way …
Physicists have wondered for decades whether infinitely dense points known as singularities can ever exist outside black holes, which would expose the mysteries of quantum gravity for all to see. Sin…
Astronomers have the "all-clear" for an exciting test of Einstein's Theory of General Relativity, thanks to a new discovery about S0-2's star status. The orbit of S0-2 (light blue) …
Brian Greene, professor of physics and mathematics at Columbia University and co-founder of the World Science Festival, explains what we know about time travel so far. Following is a transcript of th…
In the real world, your past uniquely determines your future. If a physicist knows how the universe starts out, she can calculate its future for all time and all space. A spacetime diagram of the gra…
Using the Atacama Large Millimeter/submillimeter Array (ALMA) to observe an active galaxy with a strong ionized gas outflow from the galactic center, a team led by Dr. Yoshiki Toba of the Academia Si…
Thanks to data collected by NASA's Chandra X-ray telescope on galaxies up to 3.5 billion light years away from Earth, an international team of astrophysicists was able to detect what is likely to…
An observatory in West Virginia picked up 15 bright radio pulses from a dwarf galaxy, 3 billion light years, earlier this year. The initial results, based on observations carried out by a team of ast…
If quantum physics states matter doesn't exist when it's not being noticed, then, without life, would the universe cease to exist? originally appeared on Quora: the place to gain and share kn…
If they exist, axions, among the candidates for dark matter particles, could interact with the matter comprising the universe, but at a much weaker extent than previously theorized. New, rigorous con…
Astronomers have discovered that our nearest big neighbour, the Andromeda galaxy, is roughly the same size as the Milky Way. The Milky Way and Andromeda prior to the merger [Credit: ICRAR] It had bee…
A new simulation of supermassive black holes -- the behemoths at the centers of galaxies -- uses a realistic scenario to predict the light signals emitted in the surrounding gas before the masses col…
A hole at the heart of a stunning rose-like interstellar cloud has puzzled astronomers for decades. But new research, led by the University of Leeds, offers an explanation for the discrepancy between…
