The complex puzzle known as little red dots has become more complete since their initial discovery by NASA’s James Webb Space Telescope in 2022. Now a particular little red dot’s spectrum is helping connect many of the pieces. A team of astronomers led by Vasily Kokorev at the University of Texas at Austin identified the […]

Magnetic fields may be the hidden force bringing both newborn stars and giant black holes together. New computer simulations suggest that magnetic fields play a crucial role in helping pairs of young stars form. The findings could explain why binary star systems are so common throughout the Milky Way and may even offer clues about [...]

A distant quasar has revealed one of the most extreme ultraviolet outflows ever observed, providing new clues about the powerful interactions between supermassive black holes and their host galaxies. A supermassive black hole more than a billion times the mass of the Sun is blasting gas through space at such extraordinary speeds that astronomers are [...]
A dark void once dismissed as cosmic dust may be a far more fascinating dance of black holes.

A new Keck Observatory study indicates that giant planets can spin faster than more massive brown dwarfs, revealing important clues about how planetary systems form and evolve. Astronomers have long suspected that a planet’s mass may be linked to how quickly it spins. In our solar system, Jupiter and Saturn rotate especially fast, each completing [...]

NASA’s Roman Telescope could reveal 100,000 hidden worlds and rewrite what we know about planets across the Milky Way. NASA’s Nancy Grace Roman Space Telescope is expected to dramatically expand humanity’s catalog of worlds beyond our solar system. Known as exoplanets, these distant planets number nearly 6,300 discoveries so far through NASA missions and other [...]

A star caught feeding on its companion has finally revealed the source of some of the galaxy’s most mysterious repeating signals. An international research team led by scientists at the University of Sydney has uncovered the strongest evidence yet explaining the origin of a puzzling type of cosmic signal. Their work has also revealed a [...]

NASA’s Fermi telescope may have finally uncovered the magnetic powerhouse behind the universe’s brightest supernovae. An international team of astronomers analyzing observations from NASA’s Fermi Gamma-ray Space Telescope has found what appears to be the first convincing detection of gamma rays from a rare type of extraordinarily bright stellar explosion known as a superluminous supernova.

Researchers say the isolated white dwarfs Gandalf and Moon-Sized define a new class of stellar remnant because they share five traits, including X-ray emission. Across the immense scale of the Universe, a single unusual object can prompt astronomers to look for others like it, sometimes leading to the recognition of an entirely new class of [...]

A new method could improve cosmology research by analyzing supernovae together with the galaxies that host them. An international collaboration led by scientists at the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) has created a new approach that may sharpen what researchers can learn about how the Universe expands and what dark [...]

A major SETI search found no artificial narrowband radio signal from K2-18b, but it sharpened the tools for future searches. K2-18b has become one of the most discussed worlds in recent exoplanet research. The planet lies 124 light-years away in the constellation Leo, inside the habitable zone of its red dwarf star. Observations from the [...]

The Sun unleashed a bizarre radio signal that kept broadcasting for 19 straight days, leaving NASA scientists stunned. A radio burst detected from the Sun in August 2025 initially appeared to be a normal solar event to NASA scientists. These bursts, which are caused by energetic particles interacting with the Sun’s magnetic fields, usually last [...]
Which comes first, the galaxy or the black hole? We don’t know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can gobble up surrounding material and merge over time to form more massive entities. But it’s hard […]
The Payload for Ultrahigh Energy Observations (PUEO) is a NASA Astrophysics Pioneers Program mission designed to detect the most energetic particles in the universe.

Scientists have discovered that ultraheavy atomic nuclei could explain some of the highest-energy cosmic rays ever observed. The particles may come from extreme events such as neutron-star mergers and collapsing massive stars. Scientists may have uncovered a new clue behind the origin of the most energetic particles ever detected in the universe. Ultrahigh-energy cosmic rays [...]

JWST has revealed a surprising daily cloud cycle on a distant hot Jupiter, giving scientists a clearer look at its atmosphere. On WASP-94A b, the forecast changes fast. Clouds made from rock-forming minerals gather in the planet’s morning skies, then vanish by evening as the atmosphere sweeps into hotter territory. This world is a hot [...]

Astronomers may be able to identify possible Dyson swarms by looking for unusually cold, clean infrared signals around long-lived stars. Since physicist Freeman Dyson introduced the idea in 1960, the “Dyson sphere” has become one of the most sought-after possible technosignatures in the search for advanced alien civilizations. The basic idea is that a civilization [...]
Look closely at this image from NASA’s Hubble Space Telescope and you’ll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily distinguished by the spikes that appear to extend outward from each star. These spikes, called diffraction spikes, are the […]

Tiny galaxies orbiting the Milky Way may hold clues to one of cosmology’s biggest mysteries. Ultra-faint dwarf galaxies are among the smallest known galaxies orbiting the Milky Way. Astronomers have long viewed them as ancient remnants from the early cosmos. Now, researchers at the Oskar Klein Centre and the LYRA collaboration have used a powerful [...]
