AI speeds up detection of neutron star mergers

New approach could aid “multimessenger” astronomy by quickly locating sources of gravitational waves emitted during these cosmic events

Artist's impression of the gravitational wave and electromagnetic radiation signals from a distant binary neutron star merger arriving at Earth. The image shows the Earth floating in space with a telescope hovering above it in the bottom left corner, while in the top right corner a pair of bright spots are emitting ghostly blue waves

Fast radio burst came from a neutron star’s magnetosphere, say astronomers

Scintillation measurements show that FRB 20221022A originated from the highly magnetized region around a neutron star, challenging existing models of conditions there

Kenzie Nimmo presenting this work at a recent conference. She's standing beneath a large screen that says "Using scintillation to identify the magnetospheric origin of FRB 20221022A", holding a microphone.

Sun-like stars produce ‘superflares’ about once a century

Highly energetic events happen much more often than previously thought, say astronomers

Artist's impression of a superflaring Sun-like star as seen in visible light. The image shows a bright golden ball with a few dark spots on it and a prominent flare emerging from the upper left side along with a flash of intense white light.

‘Buddy star’ could explain Betelgeuse’s varying brightness

As-yet-undetected stellar companion would displace light-blocking dust

Sun’s magnetic field may have a surprisingly shallow origin

New mathematical model reveals the workings of the stellar dynamo, with important implications for predicting solar storms

Are dusty quasars masquerading as Dyson sphere candidates?

Seven M-dwarfs recently identified as possible Dyson sphere candidates could be a case of mistaken identity

Stellar magnetic fields may give doomed exoplanets a temporary reprieve

Proposed mechanism could explain why the orbits of some "hot Jupiters" decay slower than expected

Artist's conception of the exoplanet WASP-12b. The exoplanet appears as a small sphere glowing red-hot, very close to a large yellow star

Dispatches from the Great North American eclipse of 2024

Viewers in parts of Mexico, the US and Canada enjoyed a rare total solar eclipse yesterday

Planet-gobbling stars are more common than we thought

Spectral analysis of stellar “twins” also suggests a significant fraction of planetary systems may be unstable

Artist's impression of a terrestrial planet being captured by a twin star

Two-faced white dwarf star leaves astronomers puzzled

Merger of two stellar remnants could explain a peculiar split between the star’s helium- and hydrogen-covered hemispheres

This artist's impression of the two-faced white dwarf star shows the star as a glowing blue-white ball, one side of which is darker and more granular-looking than the other
