Capturing Neutrinos from a Star’s Final Hours
What happens in the late stages of stellar evolution? Neutrinos — the elusive messengers of nuclear fusion in stellar interiors — might hold the answer.
Peering Into an Early Galaxy
ALMA has provided a detailed look into the interior of CR7, one of the most distant, early galaxies known.
Fraught with Spots
Astrobites reports on the challenge of starspots: if we don’t understand them, we won’t understand exoplanet atmospheres.
Featured Image: Stars from Broken Clouds and Disks
This still from a simulation captures the formation of a multiple-star system in action.
First Hours of the GW170817 Kilonova: Why So Blue?
A recent study explores the source of the early blue emission we observed when two neutron stars merged in August 2017.
Globular Clusters Shine in a Galaxy Lacking Dark Matter
Missing dark matter is not the only oddity of NGC 1052–DF2. New observations of this unusual galaxy are forcing us to rethink what we know about galaxies and the star clusters they host.
A White Dwarf Kicked Out of a Supernova
Astrobites reports on the first known white dwarf to have survived the partial explosion of a (failed) Type Ia supernova.
Asteroids from a Martian Mega Impact
Could a long-ago giant impact have flung pieces of Mars throughout our inner solar system? Numerical simulations and clues from the mineral olivine point us toward an answer.
Magnetic Fields Versus Gravity
What can dust polarization measurements tell us about the magnetic fields in the star-forming region W51?
Clues from Bent Jets
A new study explores how observations of enormous radio jets can reveal information about the environments that surround them.
A “Difference” Approach to Light Curves
Astrobites reports on how the Transiting Exoplanet Survey Satellite (TESS) will hunt for variable objects in its crowded fields.
