The map, spanning 4,000 light-years from the sun in all directions, combines a chart of space dust with the effects of a rare type of young, hot star.
At just 25, Cecilia Payne-Gaposchkin applied quantum physics to a treasure trove of astronomical observations to show that stars are mostly hydrogen and helium.
The fast radio burst came from 130 million light-years away. That proximity allowed an in-depth search for what produced the mysterious signal.
In a first, astronomers imaged a baby planet within a gap in the disk of material around a star, confirming predictions about how rings form.
Like Uranus's other 28 moons, the newfound object spotted by JWST will be named after a William Shakespeare or Alexander Pope character.
Sporting the world’s largest digital camera, the new telescope is poised to help solve some of the universe’s biggest mysteries.
Before exploding, a star shed most of its layers, giving a glimpse at a massive star’s deep interior. The event may represent a new kind of supernova.
The Webb telescope found that a far-off little red dot is the oldest known black hole, shrouded by gas that could help explain the ruby color.
Alpha Centauri A, four light-years from Earth, may host a gas giant. If confirmed, no Earthlike planets orbit in the star’s habitable zone.
The superclouds probably produce star-forming clouds of gas, since most nearby stellar nurseries are located within the giants.
