Astrophysical Sciences and Technology Colloquium: Cosmic Explosions from Binary Stars
Astrophysical Sciences and Technology Colloquium Cosmic Explosions from Binary Stars Register for Zoom Here Dr. Viraj Karambelkar NASA Hubble Fellow Columbia University Abstract: Common-envelope evolution (CEE) is a particularly important but poorly understood phase of binary stellar evolution that plays…

Two giant black holes at the heart of one galaxy may circle each other every 121 to 146 days and could merge in as little as 100 years
A hidden jet in Markarian 501 hints at a black hole pair that could merge within a century, but the evidence is still debated. Published November 5, 2026 Two supermassive black holes may be locked in orbit at the heart of the galaxy…

NASA's Hubble Telescope identifies dwarf galaxies with a missing oxygen problem—but where did it go?
37 dwarf galaxies lying within 22 million light-years of Earth have between just 4% and 25% of the oxygen that their stars are known to have produced. Scientists are not sure where the rest went. NASA's Hubble Telescope identifies dwarf galaxies with a missing…

Black-Hole Birth Hunter Launched
November 20, 2004 / 1:44 PM EST / AP The fastest-swiveling space science observatory ever built rocketed into orbit Saturday to scan the universe for violent celestial explosions that astronomers believe represent the birth screams of black holes. NASA launched the observatory - named Swift for…

Up In Smoke: Carbon-destruction In The Terrestrial Planet-forming Region Of A Young Class I Disk
[astro-ph.SR] Earth’s surface and deep mantle are strongly depleted in carbon compared to the Sun. Sublimation of solid carbonaceous material in the inner midplanes of young disks could cause this depletion. We study such thermal processing in HOPS-68, a…

The MegaWave Radio Surveyor
Astrobiology Web [astro-ph.IM] Several Decadal-level questions in astrophysics, exoplanets, astrobiology, and cosmology can be addressed only at low radio frequencies inaccessible from Earth. The MegaWave Radio Surveyor would open this largely-unexplored region of the electromagnetic spectrum with a space-based…

Oxygen collisions show evidence of jet quenching, a signature of early-universe matter
Rongrong Ma, a STAR physicist from Brookhaven Lab, said, "This analysis is pushing the boundaries to an extreme case to help us learn something about this jet quenching phenomenon and the conditions needed to generate a QGP." RHIC was built…

Can gravitational fields break and reconnect? Einstein's equations suggest they can
Their work shows that something similar can happen to gravity: Under the right conditions, gravitational field structures can also break and reconnect—a process they call "gravitational reconnection." When they do, energy moves out of the gravitational field and into…

Webb discovers something unexpected in the ice of an interstellar comet
Webb reveals unusual ice in interstellar comet 3I/ATLAS that closely resembles icy objects beyond Neptune, offering clues to planet formation. Ice from a comet born around another star looks surprisingly different from the ice in most comets in our solar…
