Researchers have discovered that the underside of the North American continent is slowly dripping away in blobs of rock. The remnants of a tectonic plate sinking into the Earth’s mantle may be the cause of this phenomenon.

Astronomers have found early evidence of the Universe’s transformation from a foggy, opaque state to a transparent one, thanks to a galaxy blazing with UV light nearly 13.6 billion years ago. The first galaxies in the Universe were born hidden within a thick “fog” of neutral gas, making them diff

Follow-up research on a 2023 image of the Sagittarius C stellar nursery in the heart of our Milky Way galaxy, captured by NASA’s James Webb Space Telescope, has revealed ejections from still-forming protostars and insights into the impact of strong magnetic fields on interstellar gas and the life cycle of stars.

“A big question in the Central Molecular Zone of our galaxy has been, if there is so much dense gas and cosmic dust here, and we know that stars form in such clouds, why are so few stars born here?” said astrophysicist John Bally of the University of Colorado Boulder, one of the principal investigators. “Now, for the first time, we are seeing directly that strong magnetic fields may play an important role in suppressing star formation, even at small scales.”

Detailed study of stars in this crowded, dusty region has been limited, but Webb’s advanced near-infrared instruments have allowed astronomers to see through the clouds to study young stars like never before.

Using the Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new warm Jupiter exoplanet located more than 1,000 light years away. The newfound alien world, designated TOI-2005 b, is about the size of Jupiter and orbits its host star on a highly eccentric orbit. The discovery was reported March 25 on the arXiv pre-print server.

NASA’s TESS is conducting a survey of about 200,000 of the brightest stars near the sun with the aim of searching for transiting exoplanets. So far, it has identified over 7,500 candidate exoplanets (TESS Objects of Interest, or TOI), of which 620 have been confirmed so far.

Located some 1,070 light years away from the Earth, TOI-2005 is a rapidly rotating F-type star. It has recently been monitored with TESS and a transit signal was detected in its light curve. Now, a group of astronomers led by Allyson Bieryla of the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Massachusetts, reports that this transit signal is of planetary nature.

Returning to Earth would be nothing without a warm welcome from (wo)man’s best friend.

Heartwarming footage captured the moment stranded Boeing Starliner astronaut Sunita Williams received a joyous reunion with her excited dogs after being stuck in space for 264 days.

Williams and fellow astronaut Barry “Butch” Wilmore finally departed the International Space Station, where they were stuck for more than nine months, and returned to Earth on March 18.
