American astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko mark the halfway point of on Tuesday, Sept. 15. The year-long literal trip around the world will study the physical and mental effects of sustained time in space. Kelly's identical twin, retired astronaut Mark Kelly, is also being examined as part of the research to determine the subtle impact of space flight on individuals with the same genetics. On Monday, Sept. 14, Scott Kelly said during a NASA press conference that...

New Horizons scientists made this false-color image of Pluto using a technique called principal component analysis to highlight the many subtle color differences between Pluto's distinct regions. The image data were collected by the spacecraft’s Ralph/MVIC color camera on July 14 at 11:11 AM UTC, from a range of 22,000 miles (35,000 kilometers). (Credits:NASA/JHUAPL/SwRI) The latest photo dump from NASA's New Horizons spacecraft — which made humanity's to the dwarf planet in July — has wowed scientists with its detailed...

Before you hit the "share" button on that story about the Earth's destruction by an asteroid this month, know this: NASA says it won't happen. An artist's rendering of a large asteroid impact on Earth. (Thinkstock/iStock/James Thew) Despite the claims from social media that the end of humanity is imminent, there is no scientific evidence that a catastrophic impact will happen between Sept. 15 and 28. The chatter and rumors spread so quickly that NASA felt it was necessary to...

Astronauts on the International Space Station are the science sweethearts of social media, regularly posting incredible photos of our planet from space. But a newly-released image from NASA, taken from above the Bahamas, is getting a lot of extra attention. This week, NASA shared an astronaut’s photo shot July 19 above Great Exhuma Island, one of the more remote islands of the Bahamas. The astronaut was trying to capture the area’s prominent tidal channels that run between the islands, where...

Scientists have analyzed the relationship between the moon’s gravitational pull and ocean tides on Earth for centuries, but a recent NASA discovery finds that our planet’s gravity may be giving something back. A NASA press release from earlier this month claims that in a manner similar to the way the moon influences our tides. Looking at images taken in 2010 from NASA’s Lunar Reconnaissance Orbiter (LRO), researchers found 14 different cracks along the moon’s surface. The cracks were linked to...

It’s not everyday that you look up to see a perfect halo shimmering across the sky. The optical phenomenon known as a parhelic circle was spotted over the skies of South Salem, New York, earlier this week, and Facebook fan Ernie LaMadeleine sent us the video. “The parhelic circle phenomenon happens when millions of ice crystals mirror the sun, forming a circular structure in the sky," said weather.com meteorologist Quincy Vagell. "Typically, only fragments of the circle are visible making...

The overall winner in the competition, "Eclipse Totality over Sassendalen." (Luc Jamet) A total solar eclipse is a sight to behold. During the new moon phase, the moon passes directly between the sun and Earth, casting dramatic shadows upon the Earth's surface, as perfectly pictured above. In the photograph, French photographer Luc Jamet snapped the eclipse, which occurred on Match 20, 2015, above Sassendalen, a valley in the Norwegian territory of Svalbard. This image won Jamet the title of ,...

Space is becoming quite a hot spot these days. From the GPS systems that get us home to satellite radio, all kinds of businesses want a place in the galactic market, but could all of this spell trouble for those of us here on Earth? , according to Marketplace.org. The space just a few hundred miles above earth has become so crowded that NASA spends $7 million each year keeping track of it all. With all of that equipment in...

One of the biggest space stories of the summer was the images we saw of the dwarf planet Pluto, which was finally photographed from up-close by NASA's New Horizons spacecraft. Those images are still rolling in, and as they make the long journey back to Earth, NASA has been releasing them to the public little by little. One such photograph, , showed clear details of the complexities of a mountain range known as theTartarus Dorsa. In the image below, the...

The ESA's Rosetta spacecraft has revealed that the Comet 67P/Churyumov–Gerasimenko, nicked 67P, has a daily freeze/thaw cycle in tune with the sun. (ESA/Rosetta/NWVCam) The latest in a stunning series of findings from the European Space Agency's Rosetta probe indicate that the surface of Comet 67P has its own freeze-thaw cycle that's in tune with its day and night, just as ice on Earth can freeze and thaw with the sun. The findings, published in the journal Nature, document 67P's daily...

A major Mars mystery has been solved, and NASA will tell the world about it on Monday. According to its website, NASA to make a major announcement about the Red Planet. The event will be held at the James Webb Auditorium at NASA's Washington headquarters. In this handout image, a sweeping panorama combining 33 telephoto images into one Martian vista presents details of several types of terrain visible on Mount Sharp from a location along the route of NASA's Curiosity...

were true: After much speculation, NASA that there are signs of liquid water on the surface of Mars. The findings, published in the journal Nature Geoscience on Monday, came from Georgia Institute of Technology doctoral candidate Lujendra Ojha and information from the Mars Reconnaissance Orbiter, which has been collecting Martian data since 2011. The tools aboard the spacecraft spotted evidence of seasonal streaks on the planet's surface, which have been identified as a type of salt known as perchlorates. These...
