A new study suggests that the comet that rambled past us from another star last year likely originated in a cold, isolated corner of the galaxy that had yet to gel into its own solar system.

NASA's Hubble Space Telescope has gotten a rare peek at the aftermath of two cosmic collisions — and helped scientists solve a decades-old mystery.

A stray comet from another star is swinging past Earth.

A day at Uranus just got a little longer.

The Hubble Space Telescope has suffered another breakdown that will limit its scientific discoveries.

NASA's new space telescope is doing well more than a week after liftoff, following a pair of problems overcome by ground controllers.

A U.S. survey of astronomers puts the search for extraterrestrial life at the top of their to-do list for the next 10 years.

The Hubble Space Telescope should be back in action soon, following a tricky, remote repair job by NASA.

The Hubble Space Telescope has been hit with computer trouble.

Some of the new Caldwell images include celestial gems that can be spotted with a telescope, binoculars or the naked eye. Originally, the space telescope was designed to last 15 years in orbit. This Hubble image captures Caldwell 78 (or NGC 6541), a globular star cluster roughly 22,000 light-years from Earth. When Hubble first began returning science data, astronomers did not see the clear images expected but fuzzy stars. The space agency is building another even more powerful telescope called the James Webb Space Telescope that will ultimately replace Hubble.

The Hubble Space Telescope turned 30 years old this year and to celebrate, NASA is releasing 30 never-before-seen images of the wonders of space. The photos show galaxies, star clusters and nebulae, all of which are visible from a home telescope. [TRENDING: First doses of vaccine sent across US | OK if drivers can’t see out rear window? The Hubble Space Telescope has been capturing dazzling images like these since it was launched into space in April of 1990. You can see dozens of images and learn the science behind them by visiting NASA’s website.

CAPE CANAVERAL, Fla. – Jupiter and its enticing moon Europa shine in a new photo by the Hubble Space Telescope. Hubble snapped the picture last month when the planet was 406 million miles (653 million kilometers) away, and the Space Telescope Science Institute in Baltimore released it Thursday. Europa, which is smaller than our own moon, appears as a pale dot alongside its giant, color-streaked gas planet. NASA plans to launch a spacecraft, the Europa Clipper, later this decade to see if conditions there might be ripe for life. ___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

CAPE CANAVERAL, Fla. – The launch of NASA’s successor to the Hubble Space Telescope faces seven more months of delay, this time because of the pandemic and technical issues. Officials announced Thursday that the James Webb Space Telescope — the space agency's top science priority — is now scheduled to launch on Oct. 31, 2021. Budget reserves set aside two years ago during the last major assessment will cover any additional expenses, said Thomas Zurbuchen, the space agency's science mission chief. The sun shield is needed to keep the infrared telescope cold once in space. NASA plans to ship Webb next summer to its European launch site in French Guiana — Europe's contribution to the mission.
