NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) has captured a stunning view of supernova remnant ...

One of the largest known stars in the cosmos is poised for catastrophe. After witnessing the massive object undergo a dramatic transformation, a team of astronomers say the star is on the verge of ...

The James Webb Space Telescope is weighing in on a longstanding debate over why we don’t see more of the most massive red supergiant stars go supernova. NASA/ESA/CSA/Northrop Grumman In recent years, ...

Astronomers at Michigan State University and the University of Michigan have teamed up on research that's taken the highest-resolution images to date of star explosions called novae (the plural of ...

"The sheer amount of radiated energy from these bursts is so large that you can't power them with a core collapse stellar explosion — or any other type of normal stellar explosion." When you purchase ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

A space explosion detected this summer burned for days on end, making it the longest and most unusual gamma-ray burst ever seen. Gamma-ray bursts are the universe’s most powerful explosions. They ...

Astronomers once struggled to measure the true size of the universe. Then came the discovery of Type Ia supernovae — explosions so consistent in brightness they could serve as “standard candles.” By ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...
