A trio of faint, 'ghostly' galaxies provides new observational hints about the nature of dark matter, suggesting what it might — and might not — be.
An astrophysicist collaborated with Claude Science to produce the first complete ultraviolet map of the sky, combining existing datasets and filling gaps with statistical inference in days instead of weeks.
IceCube scientist Juan Carlos Díaz Vélez explains the Nobel Prize-winning neutrino detection technology and why researchers hunt for cosmic particles beneath Antarctic ice.
Neutrino physicist Francis Halzen of the University of Wisconsin, Madison, has won the 2026 Nobel Prize in Physics for his decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin, opening the field of neutrino astronomy.
NASA has approved the PRIMA mission, a far-infrared space telescope that will use spare parts from the James Webb Space Telescope to launch in 2033 at a reduced cost of $1.2 billion.
A recent study suggests that Venus may have lost its moon due to gravitational forces and slow rotation, supported by computer simulations rather than a catastrophic event.
NASA astronaut Chris Williams and astrophysicist Neil deGrasse Tyson discuss human spaceflight and astrophysics in a podcast episode, exploring our understanding of the universe through telescopes and space missions.
This paper reviews the adaptation of stochastic differential equations with neural networks for astrophysical time series analysis, introduces Continuous-Delayed-Memory Stochastic Gradient Descent for improved optimization, and proposes a continuous-time reinforcement learning framework.
Astronomers are debating the nature of mysterious 'little red dots' observed by the James Webb Space Telescope, with some proposing they are a new type of object called black hole stars.
A paper in Physical Review D suggests that neutrinos changing flavor inside supernovae could carry energy away, potentially explaining discrepancies in core-collapse supernova models and observed rates.
A wandering black hole has been observed consuming matter while on the run, revealing its dynamic behavior in space.
NASA's Nancy Grace Roman Space Telescope features an experimental coronagraph with adaptive optics technology, aiming to directly capture starlight reflected off exoplanets for the first time, representing a major advancement in space-based astronomy.
ALMA observations reveal long-lived hotspots on Betelgeuse's surface, persisting for at least seven years, which challenges current stellar models and provides insights into the star's convective motions.
The paper argues that the singularity at the center of a black hole is a surface, not a point, based on causal disconnection in general relativity, with implications for quantum gravity.
NASA's Nancy Grace Roman Space Telescope is set to launch, aiming to explore dark matter, dark energy, and discover up to 200,000 new exoplanets with its wide-field view.
This 2024 paper examines the effects of strong gravitational lensing and microlensing on supernovae, providing potential insights into cosmological phenomena.
