Unusually Lightweight Black Hole Candidate Spotted by LIGO
In May 2023, shortly after LIGO (Laser Interferometer Gravitational-wave Observatory) turned back on for its fourth run of observations, it detected a gravitational-wave signal from the collision of an object,…
Innovative sensing platform unlocks ultrahigh sensitivity in conventional sensors
Optical sensors serve as the backbone of numerous scientific and technological endeavors, from detecting gravitational waves to imaging biological tissues for medical diagnostics. These sensors use light to detect changes…
Chemical reactions can scramble quantum information as well as black holes
If you threw a message in a bottle into a black hole, all of the information in it would become completely scrambled down to the quantum level. Because this scrambling…
NASA’s JWST probes an extreme starburst galaxy
An international team of astronomers has used NASA’s James Webb Space Telescope (JWST) to produce the highest-resolution image of spectacular exploding stars ever seen. The Messier 82 (M82) galaxy, located…
From Earth to Mars: Transporting spin information at the speed of light
Scientists have used electrical pulses to manipulate magnetic information into a polarized light signal, a discovery that could revolutionize long-distance optical telecommunications between Earth and Mars. The breakthrough, described in…
The 5 stages of the 2024 total solar eclipse explained for April 8
On Monday, April 8, the 2024 total solar eclipse will sweep through the sky over North America. While all of North America and Central America will experience at least a…
The April 8 total solar eclipse will bring weird sights, sounds and feelings
On Monday (April 8), the sky over a swathe of North America will briefly darken as the moon covers the sun completely during a total solar eclipse. For a maximum…
ESA and NASA team up to study solar wind
Both Solar Orbiter and Parker Solar Probe have very eccentric orbits, meaning that they fly in near to the Sun to get a close-up look, and then fly far out…
NASA’s Europa Clipper Survives and Thrives in ‘Outer Space’ on Earth
In less than six months, NASA is set to launch Europa Clipper on a 1.6-billion-mile (2.6-billion-kilometer) voyage to Jupiter’s ocean moon Europa. From the wild vibrations of the rocket ride to the…
