Too Many Stars, Too Fast?
Astrobites reports on galaxies that may be forming a remarkable number of stars in the first few hundred million years of the universe.
HIP 41378f — a cold, puffy exoplanet with four known siblings — becomes one of just a handful of planets with an estimate of its rotation period.
Messier 82 (Star)bursts onto the Scene!
Astrobites reports on the results of a cosmic-ray investigation of the starburst galaxy Messier 82 using the VERITAS gamma-ray telescopes.
What at first appeared to be an unremarkable low-mass galaxy cluster has been revealed to host a rare pair of parenthesis-shaped radio sources.
What is pulling exoplanet XO-3b out of alignment with its host star? A recent study explores the system and reveals an emerging trend that provides a boundary for planet formation mechanisms.
A New Way to Measure Black Hole Spin
Sensitive polarized-light observations of the relativistic jets of supermassive black holes may provide an entirely new way to measure the spin of a black hole.
Astrobites reports on an investigation of Cloud-9, a cloud of hydrogen gas that may be a galaxy containing dark matter but no stars.
Mark your calendars for a few tens of millions of years in the future: a core-collapse supernova at just 228 light-years away is sure to be spectacular.
From its vantage point in orbit around Saturn, the Cassini spacecraft captured the brilliant gleam of sunlight reflecting off of Titan’s oily hydrocarbon seas. New research explores what sunglint can tell us about the interaction between Titan’s seas and atmosphere.
