A Close Look at an Ancient Moon
Researchers present the first-ever millimeter-wavelength map of Callisto, the coldest and most weather-worn of Jupiter’s major moons.
New simulations suggest the outer solar system could disassemble within about one billion years after the Sun becomes a white dwarf.
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.
New radio observations provide the best view yet of the WISPIT 2 planetary system, revealing spiral wakes driven by a growing young planet.
Researchers use stellar pulsations to detect substellar companions around A-type stars — including what could be a first-of-its-kind exoplanet.
Handwritten eclipse observations and sketches of solar prominences from 1733 offer researchers a rare window into a data-poor period of solar history.
Astrobites reports on a hunt for evidence of a universal initial mass function using JWST observations of local relic galaxy Boötes I.
See the famous Crab Nebula in a whole new way: researchers have mapped the 3D kinematic structure of the nebula and investigated a jet-like feature emerging from the expanding shell.
A recent study has found that the observed mass–eccentricity relation of warm Jupiters can be explained by dynamical interactions between planets in these systems.
