Using wobbling stellar material, astronomers measure the spin of a supermassive black hole for the first time
Using wobbling stellar material, astronomers measure the spin of a supermassive black hole for the first time
The results offer a new way to probe supermassive black holes and their evolution across the universe. Astronomers at MIT, NASA, and elsewhere have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting. The method takes advantage of a black hole tidal disruption event - a blazingly bright moment when a black hole exerts tides on a passing star and rips it to shreds.

The origin of the sun's magnetic field could lie close to its surface
The origin of the sun’s magnetic field could lie close to its surface
Sunspots and flares could be a product of a shallow magnetic field, according to surprising new findings that may help scientists predict space weather. The sun's surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action.

Webb telescope offers first glimpse of an exoplanet's interior Methane found in WASP-107 b reveals core mass, turbulent skies, and other key insights in the search for habitable worlds beyond our solar system A surprisingly low amount of methane and a super-sized core hide within the cotton candy-like planet WASP-107 b. The revelations, based on data obtained by the James Webb Space Telescope , mark the first measurements of an exoplanet'

Webb detects most distant black hole merger to date
An international team of astronomers, led by the University of Cambridge, has used the James Webb Space Telescope to find evidence for an ongoing merger of two galaxies and their massive black holes when the Universe was only 740 million years old. This marks the most distant detection of a black hole merger ever obtained and the first time that this phenomenon has been detected so early in the Universe.

New Earth-sized world orbiting an ultra-cool star
A new, Earth-sized planet orbiting an ultra-cool red dwarf star, has been detected by an international team of astronomers - just 55 light years away. The planet is only the second of its kind to be discovered around this type of star. Called SPECULOOS-3 b, it takes around 17 hours to complete an orbit of the star which is more than twice as cold as our sun, as well as ten times less massive and a hundred times less luminous.

Newly discovered Earth-sized planet may lack an atmosphere
Circling a cold, Jupiter-sized star, the new world could offer an unobstructed view of its surface composition and history. Astronomers at MIT, the University of Liège, and elsewhere have discovered a new planet orbiting a small cold star, a mere 55 light years away. The nearby planet is similar to Earth in its size and rocky composition, though that's where the similarities end.

Robotic ’SuperLimbs’ could help moonwalkers recover from falls
A new MIT system could help astronauts conserve energy and extend missions on the lunar surface. Need a moment of levity' Try watching videos of astronauts falling on the moon. NASA's outtakes of Apollo astronauts tripping and stumbling as they bounce in slow motion are delightfully relatable. For MIT engineers, the lunar bloopers also highlight an opportunity to innovate.

Discovery of a planet around an ultra-cool star
Artist's concept of the exoplanet SPECULOOS-3 b orbiting its ultra-cool red dwarf star. The planet is as big as Earth, while its star is slightly larger than Jupiter, but much more massive. Credit: NASA/JPL-Caltech An international team of astronomers - including members of the NCCR PlanetS , the University of Geneva and the University of Bern (UNIBE) - has discovered, for only the second time, an Earth-sized exoplanet (SPECULOOS-3 b) around an ultra-cool Red Dwarf star.

Tour de force: Western Space researchers chart Orion Nebula like never before
Els Peeters, Jan Cami and collaborators among first scientists to use James Webb telescope for research and they targeted star formation Star and planet formation is a messy affair. It starts with the gravitational collapse of a gigantic cloud of gas and dust, which simultaneously produces massive stars, whose intense radiation field creates a harsh environment, as well as more modest stars, like our Sun, surrounded by a planet-forming disk that is rich in organic materials.

Astronomers spot a giant planet that is as light as cotton candy
The new world is the second-lightest planet discovered to date. Astronomers at MIT, the University of Liège in Belgium, and elsewhere have discovered a huge, fluffy oddball of a planet orbiting a distant star in our Milky Way galaxy. The discovery, reported today in the journal Nature Astronomy , is a promising key to the mystery of how such giant, super-light planets form.

NASA Images Help Explain Eating Habits of Massive Black Hole
Data from NASA's retired Spitzer Space Telescope has given scientists new insights into why some supermassive black holes shine differently than others. These images of the Andromeda galaxy use data from NASA's retired Spitzer Space Telescope. Multiple wavelengths are shown in the image on the left, revealing stars, dust, and areas of star formation.

The search is on for signs of the first stars in the universe
Yale's Priyamvada Natarajan and colleagues say the first stars left behind distinctive flares that can be detected by a new generation of space telescopes. Astronomers at Yale and the University of Hong Kong have proposed a new strategy for finding the universe's first stars - by looking for signs of their final, fiery flares.

Hints of a possible atmosphere around a rocky exoplanet
Hints of a possible atmosphere around a rocky exoplanet
Researchers using NASA/ESA/CSA James Webb Space Telescope may have detected an atmosphere surrounding 55 Cancri e, a rocky exoplanet 41 light-years from Earth. This is the best evidence to date for a rocky planet atmosphere outside our solar system. Brice-Olivier Demory, Professor of Astrophysics at the University of Bern and member of the the National Centre of Competence in Research (NCCR) PlanetS, was part of the international research team that just published the results in Nature.

This artist's concept shows what the exoplanet 55 Cancri e could look like. Observations by NASA's Webb telescope suggest it may be surrounded by an atmosphere rich in carbon dioxide or carbon monoxide, which could have bubbled up from of an ocean of. Credit: NASA, ESA, CSA, Ralf Crawford (STScI)" While the planet is too hot to be habitable, detecting its atmosphere could provide insights into the early conditions of Earth, Venus, and Mars.

Astronomers observe elusive stellar light surrounding ancient quasars
The observations suggest some of earliest "monster" black holes grew from massive cosmic seeds. MIT astronomers have observed the elusive starlight surrounding some of the earliest quasars in the universe. The distant signals, which trace back more than 13 billion years to the universe's infancy, are revealing clues to how the very first black holes and galaxies evolved.

A 'cosmic glitch' in gravity
A ’cosmic glitch’ in gravity
A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential "cosmic glitch" in the universe's gravity, explaining its strange behaviour on a cosmic scale. For the last 100 years, physicists have relied upon Albert Einstein's theory of "general relativity" to explain how gravity works throughout the universe.

Clouds blanket the night side of the hot exoplanet WASP-43b
High temperatures and extreme wind speeds influence the chemistry inside the planet's atmosphere. Using the James Webb Space Telescope (JWST), a team of astronomers, including scientists from MPIA, constructed a global temperature map of the hot, gas giant exoplanet WASP-43b.

Enceladus Spills Its Guts through Strike-Slip Motion
Over the course of its elliptical orbit, the moon Enceladus is squeezed unevenly by Saturn's gravitational pull and deforms from a spherical shape into a football shape and back again. This cyclic stress causes a phenomenon called "tidal heating" within Enceladus and dissipates enough energy to maintain what is believed to be a global ocean underneath the moon's icy crust.
