One of the best Black Friday streaming deals has landed as Apple TV is over 50% off for six months, so you can stream Pluribus, Severance and more, for less.
All of the proposals floating around out there for invoking dynamical dark energy are a little on the weak side. In many cases, they raise more questions than answers.
NASA has pointed its fleet of spacecraft at comet 3I/ATLAS to collect new footage of the interstellar invader. The agency has also said "all evidence points to it being a comet."
The U.S. Senate will hold a hearing on Dec. 3 to consider the re-nomination of billionaire tech entrepreneur Jared Isaacman as NASA chief.
One of the things the James Webb Space Telescope revealed to us is a class of small, distant galaxies in the very early Universe. Their light has been stretched into the red after billions of years travelling in the expanding Universe, and they've been dubbed Little Red Dots (LRD). Initially, the JWST couldn't reveal their true nature because LRDs are near the limits of the powerful telescope's observational power. But we know they're there; the genie's out of the bottle.
The process of star formation is one of the most fundamental and awe-inspiring phenomena in the universe. It begins within vast, cold, and dense clouds of gas and dust known as molecular clouds or stellar nurseries. These clouds are primarily composed of hydrogen, helium, and trace amounts of heavier elements.
"For me, it is particularly interesting to see how such an interstellar object evolves."
All roads lead to New Vegas as Prime Video's sci-fi series returns Dec. 17.
The most distant moon since March 2020 takes to the sky today, but you won't be able to see it.
Hawking radiation has never been proved, but it's generally thought to be real. Essentially, the argument is that when you combine black hole event horizons with quantum fuzziness, thermal energy can escape a black hole. We don't have a fully quantum theory of gravity, but we do have several semi-classical models that support the existence of Hawking radiation. And if Hawking radiation is true, then the interaction of black holes is governed by the laws of thermodynamics.
Rocket Lab launched its HASTE suborbital vehicle for the sixth time ever on Tuesday (Nov. 18), sending several test payloads up for the U.S. military.
The latest 'Predator' is a fun throwback to the '80s and '90s, when silliness and comedy were a key part of the action formula
We rate the DJI Mini 4K as our best beginner drone, but it's even better when you buy it with these handy accessory packs, with savings of at least 20%
The Pleiades star cluster is part of a much larger complex that stretches across the entire sky, a new study shows.
When a severe G4 geomagnetic storm hit, this Dreamliner pilot had the perfect front-row seat.
Astronomer Gianluca Masi captured breathtaking imagery of solar system comet C/2025 K1 (ATLAS) breaking into multiple pieces after being warmed by the sun.
Katalyst Space Technologies will use Northrop Grumman's air-launched Pegasus rocket for its upcoming mission, which will send a spacecraft to boost the orbit of NASA's Swift space telescope.
Tracking down black holes at the center of dwarf galaxies has proven difficult. In part that is because they have a tendency to “wander” and are not located at the galaxy’s center. There are plenty of galaxies that might contain such a black hole, but so far we’ve had insufficient data to confirm their existence. A new paper from Megan Sturm of Montana State University and her colleagues analyzed additional data from Chandra and Hubble on a set of 12 potential Active Galactic Nuclei (AGN) galaxy candidates. They were only able to confirm three, which highlights the difficulty in isolating these massive wanderers.
The Very Large Telescope's interferometer targeted four lasers toward the Tarantula Nebula to create an artificial star.
Researchers using the NASA/ESA/CSA James Webb Space Telescope have confirmed an actively growing supermassive black hole within a galaxy just 570 million years after the Big Bang. Part of a class of small, very distant galaxies that have mystified astronomers, CANUCS-LRD-z8.6 represents a vital piece of this puzzle and challenges existing theories about the formation of galaxies and black holes in the early Universe. The discovery connects early black holes with the luminous quasars we observe today.
The Lunar Reconnaissance Orbiter Camera has identified a never-before-seen crater on the moon's surface.
