SPHEREx

Astrobites reports on NASA’s SPHEREx mission, which is collecting an infrared spectrum for every point in the sky — potentially revolutionizing our understanding of cosmic inflation, galaxy formation, and interstellar ices.

AT 2025ulz within its host galaxy

Last year, gravitational wave detectors triggered on what may have been a collision involving a sub-solar-mass neutron star. New research investigates a potential link between this event and a supernova.

An Early Discovery by Rubin Observatory

Astrobites reports on the discovery of a new ultra-faint dwarf galaxy in preview data taken before the start of Vera C. Rubin Observatory’s 10-year survey.

WISPIT 2b

New radio observations provide the best view yet of the WISPIT 2 planetary system, revealing spiral wakes driven by a growing young planet.

Stellar field observed by ESO.

Researchers use stellar pulsations to detect substellar companions around A-type stars — including what could be a first-of-its-kind exoplanet.

A New Look at a Centuries-Old Solar Eclipse

Handwritten eclipse observations and sketches of solar prominences from 1733 offer researchers a rare window into a data-poor period of solar history.

star-forming region N44

Astrobites reports on a hunt for evidence of a universal initial mass function using JWST observations of local relic galaxy Boötes I.
