Astronomers defy the zone of avoidance to find hundreds of new galaxies
There is a region of the sky where astronomers fear to look. Filled with dark clouds of dust, it hides an unseen mass. A mass so large it is pulling the Milky Way and other galaxies toward it.

Discovery of three galactic 'red monsters' in early universe challenges current models of galaxy formation
An international team led by the University of Geneva (UNIGE) has identified three ultra-massive galaxies—nearly as massive as the Milky Way—already in place within the first billion years after the Big Bang.

Observations explore icy protoplanetary disk of the star PDS 453
Using ESO's Very Large Telescope (VLT), an international team of astronomers has inspected an icy protoplanetary disk of a young star known as PDS 453. Results of the new study, published on the preprint server arXiv, yield ...
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 ...
