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.....»»
FAST detects 3D spin-velocity alignment in a pulsar
Pulsars—another name for fast-spinning neutron stars—originate from the imploded cores of massive dying stars through supernova explosion......»»

Using cosmic-ray neutron bursts to understand gamma-ray bursts from lightning
Analysis of data from a lightning mapper and a small, hand-held radiation detector has unexpectedly shed light on what a gamma-ray burst from lightning might look like—by observing neutrons generated from soil by very large cosmic-ray showers. The.....»»
A superluminous supernova from a massive progenitor star
Stars greater than about eight solar-masses end their lives spectacularly as supernovae. These single-star supernovae are called core collapse supernovae because their dense cores, composed primarily of iron at this late stage of their lives, are no.....»»

Ultra-high-energy gamma rays originate from pulsar nebulae
The discovery that the nebulae surrounding the most powerful pulsars are pumping out ultra-high-energy gamma rays could rewrite the book about the rays' galactic origins. Pulsars are rapidly rotating, highly magnetized collapsed stars surrounded by n.....»»
Cracking Open the Mystery of How Many Bubbles Are in a Glass of Beer
After pouring beer into a glass, streams of little bubbles appear and start to rise, forming a foamy head. As the bubbles burst, the released carbon dioxide gas imparts the beverage's desirable tang. But just how many bubbles are in that drink? The A.....»»
