We summarize the week's scientific breakthroughs every Thursday.
Scientists have identified the edge of galaxy IC 1101 and crowned it with the title of largest known galaxy.
Scientists have finally seen a long-predicted motion on the sun, and it may help explain explosive solar activity.
A century of hints has suggested the famed red supergiant had a star pal but seeing it amid Betelgeuse’s brightness has been hard — until now.
Scientists have identified four types of black holes, classified mostly by their masses. But these mysterious objects continue to challenge our understanding of the universe.
Prior moon rock samples, including from Apollo, seem heavily influenced by one impact. The farside samples tweak the story.
The object orbits a brown dwarf that orbits a star, and astronomers aren’t sure if it’s a planet, a moon — or something else entirely.
Astronomers found a helium atmosphere around a rocky exoplanet — a good sign for the search for life outside the solar system.
The brine-formed meteorite that crashed into a New Jersey roof in 2024 could teach us about how life first arrived on Earth.
In sci-fi, AI can navigate the unknowns and — ideally — keep human travelers safe. But it’s not intelligent enough to do that yet.
