Pluto hogs the spotlight in the continuing scientific debate over what is and what is not a planet, but a less conspicuous argument rages on…
New research shows the first evidence of strong winds around black holes throughout bright outburst events when a black hole rapidly consumes mass. The study,…
The hottest point on a gaseous planet near a distant star isn’t where astrophysicists expected it to be – a discovery that challenges scientists’ understanding…
New model connects the origins of very high-energy neutrinos, ultrahigh-energy cosmic rays, and high-energy gamma rays with black-hole jets embedded in their environments. One of…
Like the waistband of a couch potato in midlife, the orbits of planets in our solar system are expanding. It happens because the Sun’s gravitational…
An axion is a hypothetical elementary particle whose existence was postulated in order to explain why certain subatomic reactions appear to violate basic symmetry constraints,…
Dust is everywhere — not just in your attic or under your bed, but also in outer space. To astronomers, dust can be a nuisance…
When scientists searching for exoplanets — worlds located beyond our solar system — first spotted patterns in disks of dust and gas around young stars,…
For many years, astronomers had a simple view of our Milky Way’s central hub, or bulge, as a quiescent place composed of old stars, the…
Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets…
At a special session held during the American Astronomical Society meeting in Washington, D.C., scientists on the Dark Energy Survey (DES) announced today the public…
A rapidly growing black hole — known as an active galactic nuclei — has been seen turning off and then on again. This supermassive black…
Astronomers are observing star-forming regions in our galaxy with NASA’s flying telescope, the Stratospheric Observatory for Infrared Astronomy, SOFIA, to understand the processes and environments…
Astronomers have looked back to a time soon after the Big Bang, and have discovered swirling gas in some of the earliest galaxies to have…
Recent observations of a mysterious and distant object that emits intermittent bursts of radio waves so bright that they’re visible across the universe provide new…
Through first-of-their-kind supercomputer simulations, researchers, including a Northwestern University professor, have gained new insight into one of the most mysterious phenomena in modern astronomy: the…
Astronomers from NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, Northwestern University, and the University of Maryland were on hand at the 231st meeting of the…
