Earth's potassium arrived by meteoritic delivery service finds new research led by Carnegie's Nicole Nie and Da Wang. Their work, published in Science, shows that some primitive meteorites contain a different mix of potassium isotopes than those found in other, more-chemically processed meteorites. These results can help elucidate the processes that shaped our Solar System and determined the com NASA's Juno Team assessing camera after 48th flyby of Jupiter

The JunoCam imager aboard NASA's Juno spacecraft did not acquire all planned images during the orbiter's most recent flyby of Jupiter on Jan. 22. Data received from the spacecraft indicates that the camera experienced an issue similar to one that occurred on its previous close pass of the gas giant last month, when the team saw an anomalous temperature rise after the camera was powered on in pre Data from the first SLS flight to prepare NASA for future Artemis missions

NASA continues to evaluate data and learn more about the Space Launch System (SLS) rocket's debut performance during the agency's Nov. 16 Artemis I launch. Following an initial data assessment and review that determined the SLS rocket met or exceeded all performance expectations, SLS engineers are now taking a closer look at the Moon rocket's performance to prepare for the first crewed Artemis m Searching for buried treasure on Mars with RIMFAX

What do the Perseverance rover and Superman have in common? They both can "see" through solid rock! Superman has X-ray vision whereas Perseverance has RIMFAX, a ground penetrating radar or GPR, located on the lower rear of the rover. RIMFAX uses radio waves to image the subsurface rock layers as the rover drives along.

selected nine space technologies for flight testing to advance innovations that address mission needs for both the agency and the commercial space industry.
Selected as part of the NASA's 2022 TechFlights solicitation, these technologies will fly aboard commercial suborbital vehicles such as high-altitude balloons, aircraft following parabolic flight profiles, suborbital rocket-powered sys RIT scientists reach a milestone in the search for continuous gravitational waves

Scientists on the hunt for a previously undetected type of gravitational waves believe they are getting close and have refined techniques to use in upcoming observational runs. Researchers from the LIGO-Virgo-KAGRA Collaboration outlined the most sensitive search to date for continuous gravitational waves from a promising source in a paper recently published in the Astrophysical Journal Letters. Starry tail tells the tale of dwarf galaxy evolution

A giant diffuse tail of stars has been discovered emanating from a large, faint dwarf galaxy. The presence of a tail indicates that the galaxy has experienced recent interaction with another galaxy. This is an important clue for understanding how so called "ultra-diffuse" galaxies are formed.

Scientists have discovered the first gamma-ray eclipses from a special type of binary star system using data from NASA's Fermi Gamma-ray Space Telescope. These so-called spider systems each contain a pulsar - the superdense, rapidly rotating remains of a star that exploded in a supernova - that slowly erodes its companion.

An iceberg around the size of Greater London broke off Antarctica’s Brunt Ice Shelf due to a natural process called ‘calving’. The iceberg, measuring 1550 sq km, detached from the 150 m-thick ice shelf a decade after scientists first spotted massive cracks in the shelf.
