Pictured is a screenshot of NASA's visualizations of the space environment simulation. (NASA / Goddard Space Flight Center) In a new video released by NASA’s Goddard Space Flight Center Scientific Visualization Studio, simulations show experienced between January and August on its way to Pluto. The list of space weather factors New Horizons endured included a string of solar winds and some curious particle clouds that were showing some odd behavior. The clouds, known as coronal mass ejections, can be seen...

Left: A normal star in a binary system gravitationally pulls in matter from an aging companion star that has swelled to a bloated red giant that has expanded to a few hundred times its original size. Right: After a couple hundred million years, the red giant star has burned out and collapsed to the white dwarf that shines intensely in ultraviolet wavelengths. The companion star has bulked up on the hydrogen siphoned off of the red giant star to become...

Saturn's largest moon Titan glows greenish in this new composite image from NASA. (NASA) In a new infrared composite image, Saturn's largest moon glows green and blue, almost like an alter-ego of our own planet Earth. Dubbed "" by the Daily Mail, Titan's coloration in this image captured by NASA's Cassini spacecraft is due to an infrared mapping spectrometer that penetrated through the hazy atmosphere to show a detailed glimpse of Titan's surface. The image was taken during the T-114...

Water, salt or an alien city? Scientists have been wondering about the strange bright spots on dwarf planet Ceres since NASA's in March, and now a new study in the journal Nature has put the spotlight on these light spots. According to NASA,dot the dwarf planet. The glowing spots are found in Ceres' 60-mile-wide Occator crater, and new false-color images have enabled researchers to identify the nature of these blotches: They are consistent with a type of magnesium sulfate called...

It looks like Jupiter, but it's not! An illustration of the newly discovered star, W1906+40, shows a raging storm near one of its poles. (NASA/JPL-Caltech) We know that clouds can form on Earth and other planets – but scientists have just found the best evidence that clouds, and storms, can form on stars. Using NASA's Spitzer and Kepler telescopes, astronomers have found a star that's eerily similar to Jupiter. For a star, it's cooler in temperature and much smaller than...

A daily view of Earth from 1 million miles away. (NASA) Sometimes you have to step back to see the fine details. And sometimes you have to step (or fly) way back. Like a million miles back. — shorthand for Deep Space Climate Observatory — is providing NASA with that long view. Consider it the world’s longest selfie stick. The location allows it to keep a continuous eye on the sunny side of Earth and its brilliantly acronymed Earth Polychromatic...

The photo above shows the massive phytoplankton bloom in the North Atlantic Ocean captured by the Suomi NPP satellite. In recently released photos from NASA, a huge natural bloom of phytoplankton appears in the North Atlantic Ocean. The mass of phytoplankton - microscopic organisms that convert carbon dioxide into oxygen - was . A camera on NOAA’s Suomi NPP satellite was able to grab the images in September, reports UPI. Phytoplanktonblooms provide food for a host of creatures, from small...

It appears as though Santa and his reindeer won't be the only things flying through the night sky on Christmas Eve. is slated to fly by Earth, about 6.7 million miles away but still visible to those who are scouting with their telescopes – assuming they have clear, cloudless skies, of course. "The 2015 apparition is the first of five encounters by this object in the next 12 years when itwill be close enough for a radar detection," the planning...

New video from eastern Canada shows a fireball shooting through the night sky Thursday evening. Reports came in from the province of Newfoundland and Labrador just after sunset. People said they saw something move "," like a rocket. (FORECAST: ) Although it’s not confirmed if the fireball was a meteor or space junk, —dubbed the best meteor shower of the year —peaked earlier this week, according to Earth Sky. December 2015 is full of events to please skywatchers lucky enough...

This image captured aboard NASA's Cassini spacecraft shows Saturn moons Enceladus and Tethys in perfect alignment. (NASA/JPL-Caltech/Space Science Institute) It's like a lunar eclipse, only better, because this has never been seen by humans before. The Cassini spacecraft, which has been studying Saturn from the planet's orbit, got a stunning view of two moons perfectly aligned on Sept. 24. Using its narrow-angle camera, the spacecraft captured an image of Enceladus and Tethys lined up just right from afar. "At relatively...

NASA released a gorgeous shot of planet Earth from the Lunar Reconnaissance Orbiter . (NASA/Lunar Reconnaissance Orbiter ) NASA released an eye-popping photograph of the Earth over the weekend, providing an exciting new vantage point of our big blue marble planet. The space agency's robotic Lunar Reconnaissance Orbiter (LRO) captured the image at the perfect moment, revealing a fully illuminated Earth creeping up above the rocky lunar surface. The photograph recalled the famous 1968 William Anders photo of the Earth...

A streak of light seen burning across the sky in three western states was debris from a Russian rocket re-entering the atmosphere, military officials said Wednesday. A fireball seen over Arizona, Nevada and California on Tuesday nightwas an SL-4 rocket body booster from Russia that was launched Monday. U.S. Strategic Command spokeswoman Julie Ziegenhorn says the fireball seen over Arizona, Nevada and California in the Tuesday night sky was an SL-4 rocket body booster from Russia that was launched Monday....
