Quantum mechanics is the branch of physics governing the sometimes-strange behavior of the tiny particles that make up our universe. Equations describing the quantum world…
Scientists have used lab experiments to retrace the chemical steps leading to the creation of complex hydrocarbons in space, showing pathways to forming 2-D carbon-based…
A research team of multiple institutes, including the National Astronomical Observatory of Japan and University of Tokyo, released an unprecedentedly wide and sharp dark matter…
In 1929 Edwin Hubble surprised many people – including Albert Einstein – when he showed that the universe is expanding. Another bombshell came in 1998…
A team of astronomers led by Prof. Judd Bowman of Arizona State University unexpectedly stumbled upon “dark matter,” the most mysterious building block of outer…
“Cosmologists are often wrong but never in doubt,” Russian physicist Lev Landau once said. In the early days, astronomers began by observing and modeling stars…
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…
In the 1980s, researchers began discovering extremely bright sources of X-rays in the outer portions of galaxies, away from the supermassive black holes that dominate…
A research team has published a new study led by Pat Roche, professor of astrophysics at The University of Oxford, and Chris Packham, associate professor…
A dramatic magnetic power struggle at the Sun’s surface lies at the heart of solar eruptions, new research using NASA data shows. The work highlights…
Astronomers have used NASA’s Hubble Space Telescope to make the most precise measurements of the expansion rate of the universe since it was first calculated…
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…
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. Up until…
The Sun glows with a surface temperature of about 5,500 degrees Celsius (9,900 degrees Fahrenheit). On the other hand, its hot outer layer, the corona,…
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…
The biggest black holes in the Universe are growing faster than the rate of stars being formed in their galaxies, according to two new studies…
High-resolution observations with the Atacama Large Millimeter/submillimeter Array (ALMA) imaged a rotating dusty gas torus around an active supermassive black hole. The existence of such…
