Astronomers study stars and planets much younger than the Sun to learn about past events that shaped the Solar System and Earth. Most of these…
Object lies between heaviest known neutron star and lightest known black hole. An international research collaboration, including Northwestern University astronomers, has detected a mystery object…
LIGO and Virgo Find Another Surprising Binary System The harvest of exceptional gravitational-wave events from LIGO’s and Virgo’s third observing run (O3) grows. A new…
Jupiter-size planets orbiting close to their stars have upended ideas about how giant planets form. Finding young members of this planet class could help answer…
An element that could hold the key to the long-standing mystery around why there is much more matter than antimatter in our universe has been…
Most massive stars are born in binaries (and sometimes triples, quadruples, and so on—being single isn’t common for such rock stars!) As stars age, they…
Astronomers have reported the first detection of X-rays from the earliest phase of evolution of a star like our Sun. This discovery from NASA’s Chandra…
Like most galaxies, the Milky Way hosts a supermassive black hole at its center. Called Sagittarius A*, the object has captured astronomers’ curiosity for decades….
An international collaboration bringing together over 200 scientists from 13 countries has shown that the very high-energy gamma-ray emission from quasars, galaxies with a highly…
Computer simulations conducted by astrophysicists at Tohoku University in Japan, have revealed a new theory for the origin of supermassive black holes. In this theory,…
Every year, 2 million black hole mergers are missed — Australian scientists work out how to detect them, revealing a lost 8 billion light-years of…
Several years ago, planetary scientist Lynnae Quick began to wonder whether any of the more than 4,000 known exoplanets, or planets beyond our solar system,…
The NASA/ESA Hubble Space Telescope demonstrates its full range of imaging capabilities with two new images of planetary nebulae. The images depict two nearby young…
A team of astronomers, including researchers at MIT, has picked up on a curious, repeating rhythm of fast radio bursts emanating from an unknown source…
Nestled in the constellation Taurus, a spectacle of swirling cosmic gases measuring half a dozen lightyears across glows in shades of emerald and auburn. The…
Thinking Small: New Ideas in the Search for Dark Matter Since the 1980s, researchers have been running experiments in search of particles that make up…
There may be as many as one Earth-like planet for every five Sun-like stars in the Milky Way Galaxy, according to new estimates by University…
