Scanning the first images of a well-known early galaxy taken by NASA’s James Webb Space Telescope (JWST), Cornell astronomers were intrigued to see a blob of light near its outer edge.
When two black holes collide into each other to form a new bigger black hole, they violently roil spacetime around them, sending ripples called gravitational waves outward in all directions.
Science fiction writes about and postulates alternative universes to ours, but these are fictional scenarios.
NASA’s InSight lander recorded a magnitude 4 marsquake on Christmas Eve, 2021, but scientists learned only later from orbiter images the cause of that quake: a meteoroid strike estimated to be one of the biggest seen on Mars since NASA began exploring the cosmos.
UCLA astronomers think the object, X7, might be debris cloud from a stellar collision
Although it is relatively small, Enceladus — the sixth largest of Saturn’s 83 moons — has been considered by astronomers to be one of the more compelling bodies in our solar system.
Data from the James Webb Space Telescope shows the universe may have started forming star-filled galaxies earlier than previously thought.
A new study finds that the Atlantic Coast and eastern Gulf Coast of the United States are likely to see significant increases in nutrient loading in coming decades, putting those areas at heightened risk of experiencing harmful algal blooms.
NASA's Hubble Space Telescope recently reached a new milestone in its nearly 30-year mission of helping scientists measure the expansion rate of the universe.
Searching through existing data spanning 9 billion years, a University of Michigan physicist and colleagues have uncovered the first evidence of “cosmological coupling”—
Microplastic pollution can be spotted from space because its traveling companion alters the roughness of the ocean’s surface
Completing a nearly 30-year marathon, NASA's Hubble Space Telescope has calibrated more than 40 "milepost markers" of space and time to help scientists precisely measure the expansion rate of the universe -- a quest with a plot twist.
Phase transition in early universe changes strength of interaction between dark and normal matter
The chemistry of planet formation has fascinated researchers for decades because the chemical reservoir in protoplanetary discs—the dust and gas from which planets form—directly impacts planet composition and potential for life.
NASA’s JWST has scored another first in its release of stunning images: a molecular and chemical portrait of a distant world’s skies.
A new attack discovered by the University of Michigan and NASA exploits a trusted network technology to create unexpected and potentially catastrophic behavior
UCLA scientists reveal that minerals from the asteroid were produced through reactions with water more than 4.5 billion years ago
Little ‘hurricanes’ that form in the discs of gas and dust around young stars can be used to study certain aspects of planet formation, even for smaller planets which orbit their star at large distances and are out of reach for most telescopes.
Deep overturning circulation collapses with strong warming
The eerie sound of an extraterrestrial whirlwind has reached the Earth from more than 50 million miles away, thanks to the first working microphone to traverse the surface of Mars.
