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…
The monumental announcement sent shockwaves through the scientific community. “Hearing Dr. Millikan was like being present when the Curies announced the discovery of radium, Roentgen reported the first generation of X-rays or Hertz sent the first wireless waves,” reported The…
Everything you’ve ever seen or experienced on Earth was once a nebulous collection of floating gas and dust. Science is starting to understand how those particles came to take the forms you recognize today, teaching us about Earth’s primordial history…
Scientists have laid out their findings(Image: Getty Images) British-led boffins are on the edge of their first glimpse into the zeptoverse – a miniscule world where new and exotic particles may be hiding. After a staggering 42-year search, a team…
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…
Bringing people and ideas together to fund, conduct, and share transformative science. Our grants advance knowledge and strengthen connections between science and society. Discover the latest news, research, and updates. We convene scientists, mathematicians, and thinkers to share ideas and…
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…
[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…
Hidden behind the Milky Way, IC 342 is revealing new clues about star formation, magnetic fields, and the mystery of spiral galaxies. The nickname “Hidden Galaxy” reflects this unusual viewing geometry rather than any physical peculiarity of IC 342 itself. Were it…
Scientists at the University of Cambridge have succeeded in observing interactions between subatomic particles on a scale 100 billion times smaller than an atom. The achievement could open new avenues for studying dark matter, which makes up a significant proportion of…
