When Gaia meets Hubble: accurate proper motions for faint stars
A powerful new tool combines data from Gaia and the Hubble Space Telescope and accurately measures how stars move on the plane of the sky. Find out how it’s done in today’s Astrobite!
Could some short and long gamma-ray bursts have the same parents?
Today’s authors discovered a kilonova associated with a long gamma-ray burst! Read on to hear about how this might flip the gamma-ray burst world upside down.
With Great Power, Comes Great Asteroseismology
Authors of today’s paper combine powerful machine learning techniques and millions of light curves to create the first all-sky galaxy mass map.
Can you explain these long dark gaps in your cosmological resume?
Find out how dark gaps can help fill in gaps in our knowledge of reionization
The Secret of T Pyx
T Pyx is a mystery. The stellar systems appears to contain a white dwarf and companion star. However, the white dwarf is accreting mass from its companion way faster and way more efficiently than it should, resulting in novae eruptions every 30 years.
Today’s authors may have found the culprit for these frequent explosive hydrogen burnings, which should not be possible in theory.
