This monster black hole is spinning much more slowly than others. Scientists want to know why.
Scientists have measured how fast a supermassive black hole is spinning, and the result might give us a clue about how the giant formed.
A NASA telescope aboard a high-altitude balloon will float over the South Pole to study a 'star-killer'
The Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths (ASTHROS) will study an unusual "star-killer" phenomenon.
Moon rock trait offers new way to understand impact history
The moon is covered by impact craters large and small, evidence of a violent history of bombardment by celestial bodies like comets and asteroids. But these craters only record some of lunar history.
James Webb Space Telescope will get best view yet of 'failed stars' and rogue planets
One of the instrument's early programs includes performing spectroscopy on stellar nursery NGC 133 to spot the small, dark celestial bodies.
James Webb Space Telescope has comets to catch when science begins
The James Webb Space Telescope's powerful infrared instruments will be trained on three types of comets, potentially providing insight into the solar system's early life.
NASA's flying SOFIA observatory is in New Zealand for the last time
For its last international deployment, the aircraft returns to Christchurch for a seventh and final time.
NASA's Europa Clipper may crash into Ganymede, the largest moon in the solar system, at mission's end
The Europa Clipper mission, due to launch in 2024, was originally supposed to crash into Jupiter, but there's been a change of plans.
'Emerging super Crab' might be the most powerful pulsar ever discovered
Sifting through data from the Very Large Array Sky Survey, scientists have observed an object that might be a "pulsar wind nebula."
World's largest liquid mirror telescope ready to observe
The 4-meter-wide International Liquid Mirror Telescope (ILMT) at Devasthal Observatory in the central Himalayas comes online.
Newly spotted asteroid near Venus earns name from Pauma band of Native Americans
Scientists at the Palomar Observatory turned to the Pauma band, upon whose ancestral lands the facility sits, to name the asteroid, now dubbed 'Ayló'chaxnim, or 'Venus girl.'
Wobbly jets of binary star systems may affect chances of hosting life
Because Earth is the only planet known to host life as we know it, researchers have usually focused on planetary systems similar to our own when searching for extraterrestrial life.
Ultracold gas bubbles on the space station could reveal strange new quantum physics
The test was designed to study how gas behaves in microgravity, and the results may lead to future experiments with the fifth state of matter, Bose-Einstein condensates.
NASA's Perseverance Mars rover hears an alien soundscape that changes with the seasons
A year's worth of sound recordings from NASA's Perseverance rover reveals that it's very quiet on Mars.
Rocket exhaust pollution in the upper atmosphere might affect Earth's climate
A new study reveals how air pollution from rocket launches spreads in Earth's atmosphere.
This tiny space rock might be the 1st physical evidence of a rare supernova
Scientists who analyzed the chemical composition of a space rock called the Hypatia stone suspect they have discovered evidence of a rare type of supernova.
Scientists witness a white dwarf's massive X-ray explosion for the 1st time ever
European scientists used the eROSITA X-ray telescope to observe a white dwarf nova for the first time.
Amalthea: Jupiter’s unusual inner moon
Reference Learn about Jupiter’s weird inner moon Amalthea. It was not only the fifth Jovian satellite to be discovered, but it is also the fifth-largest.
The Super Flower Blood Moon eclipse will leave these lunar spacecraft in the dark
The Super Flower Blood Moon lunar eclipse means solar power trouble for spacecraft on the moon
Alpha particles and alpha radiation: Explained
Reference Alpha particles, also known as alpha radiation, are the star players in the game of alpha decay — here's everything you need to know.
A particle accelerator is now colder than space to produce 1 million X-ray pulses a second
At that temperature, the Linac Coherent Light Source (LCLS) X-ray free-electron laser will be able to accelerate electrons close to the speed of light.
Watch the Event Horizon Telescope's 'groundbreaking' Milky Way discovery online today
Science institutions around the world will stream press conferences announcing the discovery; here's your guide to tuning in.
Mars sports 'invisible' frost and dust avalanches, and scientists may finally know why
Martian frost may be camouflaged by dust, which could cause dust avalanches.
Rocky alien worlds may need to be young to support life
Scientists suggest that one of the key characteristics of a life-supporting, rocky exoplanet is that it needs to be young enough to generate heat through radioactive decay.
