Fermi spots a supernova"s "fizzled" gamma-ray burst
On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record.....»»
Astronomers spot the same supernova three times—and predict a fourth sighting in 16 years
An enormous amount of gravity from a cluster of distant galaxies causes space to curve so much that light from them is bent and emanated our way from numerous directions. This "gravitational lensing" effect has allowed University of Copenhagen astron.....»»

Image: Hubble spots squabbling galactic siblings
A dramatic triplet of galaxies takes center stage in this image from the NASA/ESA Hubble Space Telescope, which captures a three-way gravitational tug-of-war between interacting galaxies. This system—known as Arp 195—is featured in the Atlas of P.....»»
The magnetic field in the galactic outflow of M82
Messier 82 (M82) is a luminous infrared galaxy about twelve million light-years away from the Milky Way. Its burst of star formation powers the radiation and drives a bipolar superwind that originates near the core of the galaxy. The wind extends per.....»»
