Allen Schnibben’s interest in space started when he was a child. “I picked up some books about the solar system when I was in elementary school. In middle school, I got a telescope and I […]

The NASA/ESA/CSA James Webb Space Telescope has unveiled numerous stars formerly hidden by clouds of dust in a stellar nursery known as NGC 7129—a cauldron of cosmic creation, 3,300 light-years from Earth. Webb captured infrared […]

Astronomers have observed the longest-lasting central engine activity ever recorded from a gamma-ray burst. The burst occurred at a redshift of 0.8577, and the activity lasted about 27 days in the burst’s own rest frame—around […]

Evidence for hypernovae, theorized to be the most powerful explosions in the universe, has been disputed in two papers by University College London (UCL) researchers.This post was originally published on this site

The only known supernova remnant of its kind in the Milky Way has an unexpectedly intricate structure: chains of gas knots resembling pearls on a string, each wide enough to fit the solar system multiple […]

Earth seems like a troubled place right now, but at least our cosmic surroundings appear peaceful. This is not universally true, as explosions, collisions and other dangers lurk in other places and times.This post was […]

Galactic black holes are cosmic mitochondria, powerhouses of the universe. Most of the energy these supermassive black holes produce comes from the material surrounding them: superheated plasma in their accretion disks interacting with tremendous magnetic […]

The universe may be trapped in its own comfort zone, and a researcher in the College of Engineering and Computer Science has helped explain why it cannot seem to leave. A new study suggests the […]

Like Earth, most planetary bodies circle their star in stable, detached orbits. These companionable systems can suddenly change when a planet comes too close to its star. In such a close encounter, a star can […]

Deep space travel comes with a huge potential downside—radiation exposure that can kill an astronaut either quickly or slowly over time if not managed correctly. But what exactly does that mean, and is there any […]
