Neutron stars, despite their extremely dense and compact nature, are geologically active. Pulsars, which are neutron stars with strong magnetic fields, emit beams of radio…
The Hubble Space Telescope discovers an 11-billion-year-old galaxy hidden in the bright light of a quasar
A group of galaxies called Stephan’s Quintet, contains a rogue galaxy that is actually much closer to Earth than other galaxies. (Image credit: NASA, ESA…
Research shows that supermassive black holes influence the chemical composition of their host galaxies
New research shows that the supermassive black hole at the center of the galaxy can directly impact the chemical distribution of the host galaxy. This…
Do all voids in the protoplanetary disk contain planets?
About 5 billion years ago, the Earth was forming. Gas and dust accumulated alongside the young Sun’s protoplanetary disk, perhaps pushed a little by the…
Collisions of galaxy clusters challenge the standard model of the universe
Composite color image of the interacting galaxy cluster El Gordo, showing X-ray light from NASA’s Chandra X-Ray Observatory in blue, optical data from the European…
Another object has been discovered emitting strange radio signals in our galaxy
A strange radio signal emanating from a location 15,000 light-years away could indicate an as-yet-unconfirmed type of star. Called GPM J1839-10, this particular cosmic object…
Webb Discovers Methane, Carbon Dioxide in Atmosphere of K2-18 b
A new investigation with NASA’s James Webb Space Telescope of K2-18 b, an exoplanet 8.6 times more massive than Earth, has revealed the presence of…
Medieval manuscripts likely hid traces of a recurring nova
About every 80 years, a faint 10th-magnitude star in the constellation Corona Borealis dramatically increases in brightness. This star, T CrB, is known as a…
Polaris is the closest and brightest Cepheid variable star. Something has changed recently
When you look up into the night sky and toward the North Star, you are looking at Polaris. Not only is it the brightest star…
The flares are roughly monthly due to the repeated stellar disruptions of a massive black hole
75 scientists, using NASA’s Neil Gehrels Swift Observatory, have discovered a black hole that is continuously eating away at a star similar to our Sun.…
