We’ve measured more elements in HD 222925’s spectrum than we have for any other star except for the Sun. Could this star provide a new benchmark for our understanding of how heavy metals are created?
Astrobites reports on how challenging ground-based observations can bring the aurorae of Jupiter’s moon Io into view.
An extremely flat galaxy, seen edge on, has a wealth of subtle imperfections that hold the clues to the galaxy’s history.
A recent article describes a spacecraft mission that aims to determine if Saturn’s tiny, frosty moon Enceladus hosts life in its global subsurface ocean.
Some supernovae may arise from stars that have lost their atmospheres to fierce winds or binary companions. How might we detect these binary companions, should they exist?
Astrobites reports on how the properties of galaxies in the early universe affect the Lyman-alpha light that we observe.
Astrobites reports on the molecules that might indicate life beyond Earth — and why oxygen might not be the ideal biosignature.
Intermediate mass black holes, the younger siblings of supermassive anchors of galaxies, might sometimes play with their food.
It’s summertime — beat the heat by checking out five recent research articles that tackle key issues in solar physics.
Astrobites reports on a cool star’s ultraviolet variability and explores what this means for the search for planetary magnetic fields.
A recent research article imagines what the Milky Way would look like if we could observe low-frequency gravitational waves from ultra-compact binary systems.
JWST opens a new window onto the surroundings of quasars — extremely luminous galactic centers powered by accreting supermassive black holes — in the early universe.
