New observations from NASA's James Webb Space Telescope (JWST) suggest that even extremely massive gas giants — once thought too large to form like ordinary planets — may grow ...

Discover how high-speed wavefront sensing enhances space situational awareness by overcoming atmospheric distortion.

It’s unclear whether science as a discipline—and scientists as people—will ever be able to answer some questions definitively ...

The candidate is coined HD 137010 b. It would orbit a K-type dwarf star approximately 146 light-years from Earth. The evidence comes from a single transit pattern seen in K2 data from 2017: the star ...

The planet's radius from pole to center has been revised to 66,842 km, and at the equator to 71,488 km. That makes it about 12 km smaller along the poles, and about 4 km smaller at the equator, than ...

Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields ...

Dark matter doesn’t seem to interact with the matter we can see and touch, so scientists look for it in unusual places, like faraway galaxies and underground detectors.

Hubble observations reveal a giant, turbulent planet-forming disk that may reshape theories of how planetary systems develop.

For decades, astronomers have been watching WOH G64, an enormous heavyweight star in the Large Magellanic Cloud, a galaxy ...

A new candidate exoplanet appears to almost uncanny similarities to Earth — but may differ in at least one major way.

Dwarf Lab releases the Dwarf Mini, a pocket-sized smartscope for deep-sky imaging, with 2MP RAW capture, IMX662 sensor and ...

Researchers have found what might be a little red dot transitioning into its final state, where x-rays burst through its gas cocoon. Others argue the object is nothing special ...
