After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way.



The object has settled near a...

Though our galaxy is an immense city of at least 200 billion stars, the details of how they formed...

When astronomers using NASA’s Hubble Space Telescope uncovered an oddball galaxy that looks like it...

In 2020, the Hubble Space Telescope achieved its 30th year in orbit. Hubble’s unique design, allowing it to be repaired and upgraded with advanced technology by astronauts, has made it one of NASA’s longest-living and...

On April 24, 2019, the Hubble Space Telescope celebrated its 29th year in orbit by premiering a never-before-seen view of the Southern Crab Nebula. Even after all these years, Hubble continues to uncover the mysteries of the...

The universe would be a pretty boring place without stars. Without them, the universe would remain a diffuse plasma of mostly hydrogen and helium from the big bang.

The Hubble Space Telescope has transformed our understanding of the universe, its view from orbit unleashing a flood of cosmic discoveries that have changed astronomy forever. From its discovery of dark energy to its...

Halloween is scarier with Hubble! What looks like two glowing eyes and a crooked carved smile is a snapshot of the early stages of a collision between two galaxies. The entire view is nearly 109,000 light-years...

Before 1979, there were less than a dozen known sungrazing comets. As of December 2012, we know of 2,500. Why did this number increase? With solar observatories like SOHO, STEREO, and SDO, we have not only better means of viewing the...

This video is compiled from a series of images taken on July 25 by the Transiting Exoplanet Survey Satellite. The angular extent of the widest field of view is six degrees. Visible in the images are the comet C/2018 N1,...

After several days of continued observations, scientists continue to work to determine and to understand the fate of Comet ISON: There's no doubt that the...

Comet ISON (C/2012 S1) may become a dazzling sight as it traverses the inner solar system in late 2013. During the weeks before its Nov. 28 close approach to the sun, the comet will be observable with small telescopes, and...

NASA’s Hubble Space Telescope has unveiled a spooky new image staring out from the depths of the cosmos. The new image reveals the twin galaxies AM 2026-424 — a pair of interacting galaxies that may foreshadow our Milky...

A hypnotizing vortex? A peek into a witch’s cauldron? A giant space-spider web?



In reality, it’s a look at the red giant star CW Leonis as photographed by NASA’s Hubble Space Telescope — just...

This movie from the Solar Terrestrial Relations Observatory (STEREO) shows comet PanSTARRS as it moved around the sun from March 10-15,2013 (repeated three times). The images were captured by the Heliospheric Imager (HI), an...

On April 24, 2020, the Hubble Space Telescope celebrated its 30th year in orbit by premiering a never-before-seen view of two stunning nebulas named NGC 2020 and NGC 2014. Even after all these years, Hubble continues to...

Learn the key characteristics of comets, including their icy composition, the formation of their tails as they approach the sun, and their historical significance. The video also highlights the role of comets in bringing water and...

Perseid meteor showers are caused by the debris field of the Comet Swift-Tuttle, which was first spotted in 1864.

Ancient Polynesians may have crossed the Pacific to make contact with Native Americans from the region that is now Colombia

We know that there are lots of asteroids and comets in the solar system, and we've even landed a spacecraft on a comet, so we know a reasonable amount about these objects. However in 2017, something happened that had never happened...
