SOHO image showing comet ISON approaching the Sun. ISON makes its closest approach on 28 November, when it will pass at a distance of 1.2 million kilometres above the Sun's visible surface. SOHO's instruments are expecte...

It's crunch time for a comet from the fringes of the solar system as it hurtles toward a close encounter with the sizzling sun.

To the Cassini spacecraft's infrared eyes, Saturn's graceful clouds sometimes take on the appearance of an impressionist's painting of the giant planet....

The comet has most likely disintegrated under the high heat and gravitational stress of the Sun on Nov. 28, 2013. It is not visible in Solar Dynamics Observatory footage and NASA scientists confirmed that they do not see...

Update, 4:40 p.m. EST: On Twitter, the European Space Agency (quoting SOHO scientist Bernhard Fleck) said the comet is gone. Separately, the Naval Research Laboratory’s Karl Battams posted that he thinks recent observa...

All Systems are "GO" for today's Thanksgiving Day blastoff of the upgraded SpaceX Falcon 9 rocket that could quite literally 'rock the space industry to its core' – If all goes well. Following Monday's (Nov. 25) scrub ...

UPDATED 11/29 All along, astronomers knew that there was a real possibility that Comet ISON would not survive its passage by the sun. Now it seems like the comet may in fact be in the middle of a catastrophic disintegrat...

At its meeting in Paris today, the Science Program Committee of the European Space Agency (ESA) selected the "The Hot and Energetic Universe" as the science theme for its next Large (L-class) mission.

Comet ISON is headed for a very, very hot date with the Sun. At roughly 18:37 UTC today (1:37 p.m. EST) it will be at perihelion, its closest approach to the Sun, broiling away just 1.1 million kilometers (700,000 miles)...

A quick update on Comet ISON: It brightened quite a bit last night, and then started dimming. It's still going strong, but it's unclear exactly what's happening to the comet itself. Here's a shot taken by the SOHO satell...

"Humans obviously evolved a much wider range of communication tools to express their thoughts, the most important being language," said John Hoffecker, a fellow at CU's Institute of Arctic and Alpine Research. "Individua...

Typhoons that hit Japan each year are helping spread radioactive material from the Fukushima nuclear disaster into the country's waterways, researchers say.

Today is make-or-break time for Comet ISON as it reaches perihelion, the point closest to the sun. At 1:25PM EST the comet will zoom just 730,000 miles above the solar surface, traveling at a speed of about 225,000 miles...

As the comet approaches perihelion on Nov. 28th, 2013, it has significantly brightened and its tail has started to bend . The NASA/ESA SOHO spacecraft has captured imagery.

Astronomers have long been puzzled by a certain meteor shower.

Comet ISON's close encounter with the Sun

Aboard the Earth-orbiting International Space Station, NASA astronauts Rick Mastracchio and Mike Hopkins, both Expedition 38 flight engineers, send down their best wishes for a happy Thanksgiving....

Comet ISON on the approach to the Sun

Imagine if your spacecraft was punctured and it could do the repair itself, without the need of you going outside on a dangerous spacewalk. Well, a Canadian team has a prototype idea that could lead to self-healing struc...

For the first time ever users across the globe will be able to view recent scenes and events on Earth from Space thanks to the launch this week of two new cameras built by STFC RAL (Rutherford Appleton Laboratory) Space.

Come on, admit it, you've had this question. "Since astronomers know that the Universe is expanding, what's it expanding into? What's outside of the Universe?" Ask any astronomer and you'll get an unsatisfying answer. We...

The hot and energetic Universe and the search for elusive gravitational waves will be the focus of ESA's next two large science missions, it was announced today.
