Scientists have confirmed what became of a star that exploded in a stunning supernova visible to Earth more than three decades ago.

One of the biggest and brightest stars in the night sky will momentarily vanish.

The Webb Space Telescope has captured the rare and fleeting phase of a star on the cusp of death.

Astronomers have discovered what appear to be massive galaxies dating back to within 600 million years of the Big Bang.

Astronomers have discovered 12 new moons around Jupiter, putting the total count at a record-breaking 92.

NASA's new Webb Space Telescope is finding bright, early galaxies that until now have been hidden from view.

Two space telescopes have captured this week's asteroid strike, the first planetary defense test of its kind.

Astronomers have discovered the farthest star yet, a super-hot, super-bright giant that formed nearly 13 billion years ago at the dawn of the cosmos.

The world's biggest and most powerful space telescope has reached its final destination 1 million miles away.

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.

JACKSONVILLE, Fla. – The best meteor shower of the year is only a few days away, but it’s not the only nice thing that will brighten up the night sky in December. “The beautiful thing about this is that some of these objects are naked eye objects.”Those objects include the Geminid meteor shower Sunday night. A tip for iPhone users, if you have to look at your phone, put it in red mode. Make sure it’s on color tint and that the intensity and hue are turned all the way up. It won’t happen again for another 20 years, so you won’t want to miss it!

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.

Although the timing of the latest image from the Hubble Space Telescope coincides with the upcoming July 4 holiday, the cosmic fireworks captured in it have been unfolding over two centuries. (CNN) - Although the timing of the latest image from the Hubble Space Telescope coincides with the upcoming July 4 holiday, the cosmic fireworks captured in it have been unfolding over two centuries. The source of the show is 7,500 light-years from Earth in the double star system Eta Carinae, which is in the Carina or Ship's Keel constellation. The Great Eruption, a gigantic explosion, happened in the system in 1838. But the Great Eruption was different.

In this NASA handout, the Hubble Space Telescope drifts through space in a picture taken from the space shuttle Discovery during Hubble's second servicing mission in 1997. (CNN) - The Hubble Space Telescope has identified soccer ball-shaped molecules amid the gas and dust that fills the space beyond our solar system and between other star systems. That space is known as the interstellar medium or ISM, and Hubble is exposing some of the mysterious electrically charged molecules within it. Some of the compounds that make up the interstellar medium block or absorb different wavelengths of starlight as it passes through this space. Life as we know it is carbon-based, and now carbon has been shown to form and survive in the harsh and exposed interstellar medium.
