Compton-Thick or Thin? Classifying NGC 5347
Astrobites reports on the properties of one active galaxy’s nucleus — which could help solve a long-standing mystery about X-rays in our universe.
The TESS Mission’s First Earth-Like Planet Found in an Interesting Trio
Astrobites reports on the TESS mission’s discovery of an Earth-like planet in the habitable zone of its star — and the puzzle of how this system formed.
TESS Reveals HD 118203 b Transits After 13 Years
The exoplanet hunter TESS is out searching for new worlds — but on this occasion, it saw an old one in a new light. Astrobites reports.
Why Are There so Many Sub-Neptune Exoplanets?
Sub-Neptunes are the most common planet in the galaxy, but Neptunes are much rarer. Astrobites reports on why this may be.
Combining Ground and Space-based Observations to Find EvryFlare
Low-mass stars exhibit a wide range of flare events. Astrobites reports on a coordinated effort to measure them all.
Modeling Supernovae Feedback as a Galactic Fountain
Astrobites reports on how stellar feedback can drive a galactic fountain by pushing out gas that later falls back in.
You Spin Me Right Round: Stellar Rotation with Asteroseismology
How a star spins can significantly impact its evolution — yet stellar rotation remains poorly understood. Astrobites reports on what we can learn by studying stellar pulsations.
Searching for Supernova Survivors
Supernovae may be among the most powerful events in the cosmos, but astronomers think that companion stars may be able to survive these intense explosions. Astrobites reports.
Not Far in the Dark
To confirm whether some galaxies have suspiciously low amounts of dark matter, we need to be sure how far away they are. Astrobites reports on a new approach for these measurements.
