X-ray flashes from a nearby supermassive black hole accelerate mysteriously

MIT astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that’s teetering at the black hole’s edge.

Physicists magnetize a material with light

MIT physicists created a long-lasting magnetic state in a material, using only light. The results provide a new way to control and switch antiferromagnetic materials, which are of interest for their potential to advance information processing and memory chip technology.

MIT researchers discover the universe’s oldest stars in our own galactic backyard

MIT astronomers discovered three of the oldest stars in the universe, and they live in our own galactic neighborhood. The stars are in the Milky Way’s “halo” — the cloud of stars that envelopes the entire main galactic disk — and they appear to have formed between 12 and 13 billion years ago, when the very first galaxies were taking shape.
