NASA is about to launch the world's most powerful space telescope. Webb's first year of science could rewrite the history of the universe.
NASA is just about to launch a groundbreaking space telescope. But a once-a-decade report asks the agency to start building the next one now.
NASA's iconic Earth-orbiting observatory is getting old. After Hubble's last glitch over the summer, engineers narrowed down the cause more quickly.
Etienne Léopold Trouvelot sketched the cosmos for Harvard. His pastels capture solar flares, eclipses, star clusters, and Jupiter's biggest storm.
The disc surrounding this planet has enough dust and gas to form three moons the size of our own. The halo is 500 times larger than Saturn's rings.
Hubble's first new photos show two colliding galaxies and one long galactic spiral. The telescope is also observing star clusters and Jupiter auroras.
Hubble is the world's most powerful space telescope. It has enabled astronomers to peer into the earliest ages of the universe.
Hubble has been conducting revolutionary science for 30 years, but its age is starting to catch up to it. For now, NASA can use backup hardware.
Engineers have been troubleshooting NASA's Hubble Telescope since it went offline a month ago. They think they've finally identified the problem.
Engineers have been troubleshooting NASA's Hubble Telescope since it went offline in mid-June. Now, they're going to try switching to backup hardware.
Hubble has been offline for 12 days. NASA's Hubble team is starting to think this may not be an error on the telescope's payload computer after all.
Hubble engineers thought the issue was an old memory module. But that was just a symptom of the real problem - which NASA still hasn't identified.
Hubble is hibernating to protect its scientific instruments while NASA troubleshoots the computer that controls them.
A super-Earth planet 280 light-years away seems to be about 10 billion years old, adding to growing evidence that rocky planets have existed almost as long as our galaxy. Ancient rocky planets offer further evidence that extraterrestrial life may have existed long before humans. Scientists may have better success looking […]
Astronomers can see a distant galaxy dying as it bleeds cold gas into space. Such gas is critical for forming stars. Galaxies die when they can no longer do so. This galaxy formed from a collision in which two galaxies merged into one. That left a “tail” that’s shedding 10,000 […]
China’s Aperture Spherical Radio Telescope (FAST) is the largest and last remaining giant, single-dish telescope after Arecibo’s collapse. As China’s moon mission advances, experts say the via its resolution and sensitivity, the FAST telescope will help produce critical research over the next decades. Opened in 2016, in November, Chinese state […]
New images from the world’s largest solar observatory show a sunspot in never-before-seen detail. An image and a sped-up video show powerful magnetic fields meeting hot gases boiling from below the sun’s surface. The Inouye Solar Telescope could one day help scientists predict dangerous eruptions on the sun. Visit Business […]
