Researchers have identified a pair of low-density exoplanets, TOI-791 b and c, that challenge existing theories on how planetary systems form and evolve.

NASA has opened applications for a yearlong analog mission designed to simulate the challenges of deep space travel at the Johnson Space Center. Volunteers will reside in specialized habitats to help the agency develop health and psychological protocols for future lunar and Mars expeditions.

NASA has unveiled a collection of space imagery and audio sonifications rendered in red, white, and blue to mark the United States' 250th anniversary. The project features four celestial objects captured by the Chandra X-ray Observatory and other space and ground-based telescopes.

China's Tianwen-2 mission has reached the quasi-satellite Kamoʻoalewa, initiating an effort to collect regolith and resolve the object's mysterious origins.

New research reveals that Western toads separated by the Canadian Rockies represent distinct evolutionary lineages, prompting a re-evaluation of conservation needs.

New infrared imagery from the James Webb Space Telescope offers a look at the birth of stars within the dust-shrouded FS Tau region. These findings provide evidence that protostars accumulate mass through discrete, energetic episodes rather than steady growth.

Katalyst Space Technologies has deployed its Link spacecraft to perform a robotic rescue of the Neil Gehrels Swift Observatory. The mission seeks to prevent the telescope from burning up in Earth's atmosphere by boosting it to a higher, stable orbit.

To commemorate the U.S. 250th anniversary, NASA has released a high-resolution image of the massive Messier 3 globular cluster containing 500,000 stars.

Katalyst Space Technologies launched the Link spacecraft to stabilize the Neil Gehrels Swift Observatory, which is losing altitude due to solar activity.

A robotic spacecraft is attempting an unprecedented salvage mission to rescue the decaying Neil Gehrels Swift Observatory from atmospheric reentry. This high-risk effort marks the first time an American robotic craft will attempt to service an uncrewed U.S. government satellite.

New research indicates that GJ 3378b is a rocky super-Earth rather than a gas giant, making it a key candidate for future studies of habitability.

University of Minnesota researchers have developed SpudCell, a synthetic construct that performs fundamental biological processes like growth and replication. This bottom-up engineering effort provides a platform for studying the threshold between inanimate matter and biological behavior.

An ESO study warns that the proposed launch of over 1.7 million satellites poses an existential threat to astronomy by causing severe light pollution. Researchers are advocating for a strict orbital limit of 100,000 satellites to preserve the viability of ground-based observations.

New research reveals that tectonic mantle waves raised the Antarctic landscape, allowing ice to form millions of years before global cooling reached the Arctic.

Researchers reconstructed the evolutionary history of Acinetobacter baumannii by sequencing samples dating back to the 1970s. The study reveals how the bacterium evolved in waves to acquire resistance traits and survive medical interventions.

Equipped with the world's largest digital camera, the Vera C. Rubin Observatory in Chile has begun a decade-long project to create a time-lapse of the sky. The survey aims to capture vast amounts of data to help researchers study dark energy, dark matter, and other celestial phenomena.

A mission to boost the aging Swift gamma-ray telescope's orbit has been paused following a failure to deploy the rocket. NASA is evaluating if a secondary launch attempt is feasible.

New research from the European Southern Observatory indicates that massive satellite constellations could damage astronomical research by creating light trails and elevating background sky brightness. Scientists are calling for an orbital cap to protect the ability to observe the cosmos.

A study by the European Southern Observatory warns that the rapid expansion of satellite constellations could render critical ground-based research impossible. Scientists are urging the FCC to implement strict regulatory limits to protect the night sky.

A new European Southern Observatory study warns that proposed satellite constellations could render ground-based astronomy impossible through massive light pollution and data interference.
