Reversing Winds on Hot Jupiters
The winds of exoplanets HAT-P-7b and CoRoT-2b blow in the opposite direction from what we expect. Could magnetic fields have something to do with this odd reversal?
First Disrupted Star for a New Survey
The Zwicky Transient Facility is officially open for business, and it’s already watched a black hole tear apart a star.
Can We A-void the Hubble Tension with Local Voids?
Astrobites explores the possibility that a local void is messing with our measurements of the Hubble constant along the cosmic distance ladder.
Inflating a Super-Puff Planet
Super-puffs — fluffy planets with abnormally low densities — are a problem: according to theoretical models, they shouldn’t exist.
Solving a Stellar Abundance Problem (with a Little Help from Our Oceans)
How can the behavior of Earth’s oceans help us understand chemical abundances in red-giant stars?
Clues from Hubble a Year After a Neutron-Star Merger
More than a year after the first confirmed neutron-star merger, we’re still learning from new observations.
Where Did All the Dark Matter Go?
Astrobites reports on the second detection of a galaxy apparently lacking in dark matter, which has reopened the debate about dark-matter-deficient galaxies.
Featured Image: How Gas Affects the Structure of Galaxies
These beautiful images from a simulation of a Milky-Way-like galaxy capture how gas affects a galaxy’s formation and evolution over time.
A Hazy Day Around TRAPPIST-1?
A new study explores whether the skies of the TRAPPIST-1 family of planets are likely cloudy or clear.
Holding Together a Speeding Cloud
High-velocity clouds observed in our galaxy’s halo pose a conundrum: given their tenuous nature and large speeds, why haven’t they been ripped apart?
How to Find Exoplanets and “Listen” to Their Stars with TESS
Astrobites reports on what we can gain when we use TESS not only to discover new exoplanets, but also to ‘listen’ to their host stars.
