These images show the surface of the red supergiant star Betelgeuse during its unprecedented dimming, which happened in late 2019 and early 2020. The image on the far left, taken in January 2019, shows the star at its normal brightness, while the remaining images, from December 2019, January 2020, and […]

Chandra data may have revealed the most distant known supermassive black hole with an X-ray jet. The source of this jet is a quasar (a rapidly growing black hole) at the center of a young galaxy about 12.7 billion light years from Earth. The first panel is an artist’s illustration […]

ANIMATION Scientists have long theorized that supermassive black holes can wander through space—but catching them in the act has proven difficult. Now, researchers at the Center for Astrophysics | Harvard & Smithsonian have identified the clearest case to date of a supermassive black hole in motion. Their results are published today (March […]

Artist’s rendering of a comet headed towards Earth. New theory explains possible origin of the Armageddon-causing object. It forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it’s known, left behind a crater off the coast of Mexico that spans 93 miles […]

An artist’s illustration of the Chandra spacecraft in orbit. Credit: MSFC Quasars are perhaps the best-known kinds of active galactic nuclei (AGN), galaxies whose central supermassive black holes are luminous, sometimes brighter than the rest of the galaxy. In an AGN, material accretes onto a surrounding torus of gas and […]

A five-planet system around TOI-1233 includes a super-Earth (foreground) that could help solve mysteries of planet formation. The four innermost planets were discovered by high schoolers Kartik Pinglé and Jasmine Wright alongside researcher Tansu Daylan. The fifth outermost planet pictured was recently discovered by a separate team of astronomers. Artist […]

An image of the nearby Pleiades star cluster. CfA astronomer Guillermo Torres has completed a detailed eleven-year study of intermediate mass stars in this cluster using SAO’s Fred L. Whipple Observatory Tillinghast facility. Because these stars are rapidly rotating, previous spectroscopic measurements of their motions and properties had been unreliable. […]

Artist’s depiction of a magnetar. Credit: ESO/L. Calçada Astronomers have recently found the fastest spinning and possibly the youngest magnetar known. This object, known as J1818.0-1607, is located about 21,000 light years away in the Milky Way galaxy. Magnetars are a special class of neutron stars that possess extremely powerful magnetic fields. […]

The Giant Magellan Telescope. Credit: GMTO Corportaion The Giant Magellan Telescope will be one of the few super giant earth-based telescopes that promises to revolutionize our view and understanding of the universe. It will be constructed at the Las Campanas Observatory in Chile. Commissioning of the telescope is scheduled to […]

This image shows the disc around the young star AB Aurigae in polarized near-infrared light as seen with the European Very Large Telescope’s SPHERE instrument. Measurements of the molecular components of the disk at millimeter wavelengths reveal several unexpected properties including a warmer temperature, more dust, and a deficiency of […]
