During the last five decades, springtime snow and the ice cover in the Arctic has significantly declined. As per a new research, the snow has reduced by a third in the Western Hemisphere and by almost a half near Alaska.

Researchers from NASA and the University of Washington, Seattle have assessed changes in the snow depth over years.

NASA's Hubble Space Telescope captured a new image of globular cluster IC 4499. The image shows a diamond shaped cluster of stars, which is around 50,000 light years away from Earth and orbits in Milky Way galaxy.

Scientists claimed that the image will help them to find how old that globular cluster really is.

Conspiracy theorists have often talked about hidden secrets on the moon's surface. Those stories have always remained a source of fascination. The theories were revived when a YouTube user revealed that he has found a proof of the mystical man on the moon.

The YouTube video displaying an alien's shadow has gone viral on internet. This video from user Wowforreel has been seen more than 2 million times in less than a month. Lunar images from NASA and Google Earth shows a humanoid figure walking along the surface of the moon. This proves that there is an alien on the Moon.

NASA's Orbiting Carbon Observatory-2 (OCO-2) has started relaying data. On July 2, OCO-2 was launched. It is the first in the Afternoon Constellation (A-Train), which is designed to collect information on earth's climate, weather and surface.

Comet Siding Spring will be making a close encounter with the planet Mars on October 19 as per calculations of NASA scientists. Mars Odyssey orbiting the Red planet will be force-shifted to change its orbit so that it could stay away from the possible destruction that can be caused by the passing comet. Scientists have planned to change the orbit on August 5.

Scientists are surprised to find volcanic eruptions on Jupiter's moon Io, and now believe that volcanoes are more common than previously thought. NASA scientists noticed three huge volcanic eruptions that occurred on August 2013. According to scientists, there are four 'Galilean Moons' of Jupiter, and Io is the innermost one.

There have been reports from the Goddard Space Flight Centre about a strong evidence that scientists have got that provides clues to what actually makes the outer atmosphere of the sun much hotter than the surface. The evidence suggests that nanoflares provide the extra heat. Nanoflares are spontaneous bursts of heat, which happen constantly. They cannot be detected and studied separately.
