Newfound 'glitch' in Einstein's relativity could rewrite the rules of the universe, study suggestsEinstein's theory of general relativity is our best description of the universe at large scales, but a new observation that reports a "glitch" in gravity around ancient structures could force it to be modified.

Giant 'rogue waves' of invisible matter might be disrupting the orbits of stars, new study hintsNew research shows how disruptions to binary star systems could be the key to detecting space's most confounding substance — dark matter.

Cosmic 'superbubbles' might be throwing entire galaxies into chaos, theoretical study hintsWhen there are multiple supernovas in the same galaxy, they can leave enormous voids that tamper with the balance between dark matter and regular matter. Over time, this can throw entire galaxies into chaos.

Researchers solve mystery of inexplicably dense galaxy at the heart of perfect 'Einstein ring' snapped by James Webb telescopeThe James Webb Space Telescope discovered an inexplicably dense galaxy inside an "Einstein ring" last year. Now, researchers think they can explain this cosmic conundrum.

The universe may be dominated by particles that break causality and move faster than light, new paper suggestsWith the nature of the universe's two most elusive components up for debate, physicists have proposed a radical idea: Invisible particles called tachyons, which break causality and move faster than light, may dominate the cosmos.

Some stars may be 'infected' with black holes that destroy them from within, new study hintsCould dark matter be made of mini black holes that formed in the early universe? One way to find out is to look for missing stars, destroyed by primordial black holes, a new study suggests.

Group of 60 ultra-faint stars orbiting the Milky Way could be new type of galaxy never seen beforeA new satellite galaxy discovered orbiting the Milky Way is either an incredibly ancient, soon-to-fragment clump of stars or the most dark-matter-dominated dwarf galaxy ever found.

Scientists reveal largest map of the universe's active supermassive black holes ever createdA massive new 3D map of space includes more than 1 million supermassive black hole-powered quasars, which are among the brightest objects in the universe.

James Webb telescope finds ancient galaxy larger than our Milky Way, and it's threatening to upend cosmologyAstronomers believe the first galaxies formed around giant halos of dark matter. But a newly discovered galaxy dating to roughly 13 billion years ago mysteriously appeared long before that process should have occurred.
