Asteroid Vesta could be a fragment of a solar system planet, but which one?
The interior of asteroid Vesta has been shown not to be a protoplanet after all, meaning that new explanations for its origin are needed.

Arp 184 or NGC 1961, a skewed or "peculiar" spiral galaxy, is still stunning in this image from the Hubble Space Telescope.
A giant crater on the moon may hold remnants of an ancient magma ocean. Artemis astronauts could bring home samples of it
Crewmembers on upcoming Artemis missions could potentially return samples from the moon's mantle back to Earth, providing insight into the final stages of lunar formation.
What time is it on the moon? US House space committee wants a standard lunar clock
Time moves faster on the moon, and now we're one step closer to getting a lunar time zone to keep track of it.
What would it be like living on Tatooine from ‘Star Wars’? This exoplanet orbiting twin suns could tell us
Luke found life on Tatooine to be boring, but he should be glad, because as we have seen, binary stars have the potential to play all kinds of havoc on their orbiting circumbinary planets.
A whole ‘population’ of minimoons may be lurking near Earth, researchers say
The discovery of 2024 PT5, a small, rocky body dubbed a "minimoon" during its discovery last year, hints at a hidden population of lunar fragments traveling near Earth.
James Webb Space Telescope finds coldest exoplanet ever seen, and it orbits a dead star
Astronomers using the James Webb Space Telescope (JWST) have confirmed the existence of the first known planet closely orbiting a dead star — offering new insights into how planets may evolve during the final stages of a star's life.

Galaxy cluster Abell 1489, as imaged by the International Gemini Observatory, contains more than 200 of the gravitationally-bound systems of stars, stellar remnants, interstellar gas and dust.
New JWST observations of ‘trans-Neptunian objects’ could help reveal our solar system’s past
The James Webb Space Telescope has observed surface ice methanol — a key building block for organic compounds necessary for life, including sugars — on trans-Neptunian objects.
DARPA wants a spacecraft to search for water on the moon
DARPA (the U.S. Defense Advanced Research Projects Agency) is looking for a private company to build spacecraft to orbit the moon and search for water.
