A formula for life? New model calculates chances of intelligent beings in our universe and beyond
The chances of intelligent life emerging in our universe—and in any hypothetical ones beyond it—can be estimated by a new theoretical model which has echoes of the famous Drake Equation.

Is an 'off-year' Leonid outburst in the cards for November?
It's still one of the coolest things I ever saw. I was in the U.S. Air Force in the 90s, and November 1998 saw me deployed to the dark skies of Kuwait. That trip provided an unexpected treat, as the Leonid meteors hit dramatic ...

How did supermassive black holes get so big, so early? They might have had a head start
Supermassive black holes (SMBHs) can have billions of solar masses, and observational evidence suggests that all large galaxies have one at their centers. However, the JWST has revealed a foundational cosmic mystery.

New research challenges dark matter theory in galaxy formation
The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming the popular hypothesis ...

Astronomers investigate long-term variability of blazar AO 0235+164
Astronomers have performed a comprehensive multiwavelength study of an extremely variable blazar known as AO 0235+164. Results of the new study, published Nov. 3 on the preprint server arXiv, shed more light on the long-term ...
Swirling polar vortices likely exist on the sun, new research finds
Like the Earth, the sun likely has swirling polar vortices, according to new research led by the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR). But unlike on Earth, the formation and ...

Astronomers observe an unlucky star's repeated tidal disruptions
When a star moves around a supermassive black hole (SMBH) in a close elliptical orbit, it gets partially tidally disrupted every time it reaches the pericenter, emitting a series of luminous flares, known as a partial tidal ...

Star's disappearance in Andromeda marks the birth of a black hole
Massive stars about eight times more massive than the sun explode as supernovae at the end of their lives. The explosions, which leave behind a black hole or a neutron star, are so energetic they can outshine their host galaxies ...
