Persistent “hiccups” in a far-off galaxy draw astronomers to new black hole behavior

At the heart of a far-off galaxy, a supermassive black hole appears to have had a case of the hiccups. Astronomers from MIT, Italy, the Czech Republic, and elsewhere have found that a previously quiet black hole, which sits at the center of a galaxy about 800 million light years away, has suddenly erupted, giving […]

Astronomers spot 18 black holes gobbling up nearby stars

Star-shredding black holes are everywhere in the sky if you just know how to look for them. That’s one message from a new study by MIT scientists, appearing today in the Astrophysical Journal. The study’s authors are reporting the discovery of 18 new tidal disruption events (TDEs) — extreme instances when a nearby star is […]

Study: Stars travel more slowly at Milky Way’s edge

By clocking the speed of stars throughout the Milky Way galaxy, MIT physicists have found that stars further out in the galactic disk are traveling more slowly than expected compared to stars that are closer to the galaxy’s center. The findings raise a surprising possibility: The Milky Way’s gravitational core may be lighter in mass, […]

A carbon-lite atmosphere could be a sign of water and life on other terrestrial planets, MIT study finds

Scientists at MIT, the University of Birmingham, and elsewhere say that astronomers’ best chance of finding liquid water, and even life on other planets, is to look for the absence, rather than the presence, of a chemical feature in their atmospheres. The researchers propose that if a terrestrial planet has substantially less carbon dioxide in […]

Everything, everywhere all at once

The way Morgane König sees it, questioning how we came to be in the universe is one of the most fundamental parts of being human. When she was 12 years old, König decided the place to find answers was in physics. A family friend was a physicist, and she attributed her interest in the field […]

Bright flash leads astronomers to a heavy-metal factory 900 million light years away

An extraordinary burst of high-energy light in the sky has pointed astronomers to a pair of metal-forging neutron stars 900 million light years from Earth. In a study appearing today in Nature, an international team of astronomers, including scientists at MIT, reports the detection of an extremely bright gamma-ray burst (GRB), which is the most […]

LIGO surpasses the quantum limit

The following article is adapted from a press release issued by the Laser Interferometer Gravitational-wave Observatory (LIGO) Laboratory. LIGO is funded by the National Science Foundation and operated by Caltech and MIT, which conceived and built the project. In 2015, the Laser Interferometer Gravitational-Wave Observatory, or LIGO, made history when it made the first direct […]

3 Questions: A bigger, better space-ripple detector

The search for space-shaking ripples in the universe just got a big boost. An MIT-led effort to build a bigger, better gravitational-wave detector will receive $9 million dollars over the next three years from the National Science Foundation. The funding infusion will support the design phase for Cosmic Explorer — a next-generation gravitational-wave observatory that […]

Newly discovered planet has longest orbit yet detected by the TESS mission

Of the more than 5,000 planets known to exist beyond our solar system, most orbit their stars at surprisingly close range. More than 80 percent of confirmed exoplanets have orbits shorter than 50 days, placing these toasty worlds at least twice as close to their star as Mercury is to our sun — and some, […]
