An image from the Gemini Observatory captures what is one of the brightest volcanoes ever seen in our solar system. The image, obtained on Aug. 29, reveals the magnitude of the eruption that was the 'grand finale' in a series of eruptions on the distant moon.
Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun's outer atmosphere so much hotter than its surface. The new observations of the small-scale extremely hot temperatures are consistent with only one current theory: something called nanoflares - a constant peppering of impulsive bursts of heating, none of which can be individually detected - provide the mysterious extra heat.
New research shows that more than four billion years ago, the surface of Earth was heavily reprocessed as a result of giant asteroid impacts. A new model based on existing lunar and terrestrial data sheds light on the role asteroid bombardments played in the geological evolution of the uppermost layers of the Hadean Earth.
So far, four European space freighters have carried supplies to the International Space Station (ISS). At 01:47 CEST on 30 July 2014, Georges Lemaitre - the fifth and last European Space Agency (ESA) Automated Transfer Vehicle (ATV) - lifted off from the spaceport at Kourou in French Guiana.
NASA technologists have hurdled a number of significant technological challenges in their quest to improve an already revolutionary observing technology originally created for the James Webb Space Telescope.
The Milky Way is less massive than astronomers previously thought, according to new research. For the first time, scientists have been able to precisely measure the mass of the galaxy that contains our Solar system.
A group of scientists has offered a tantalizing new possibility: these mysterious molecules may be silicon-capped hydrocarbons like SiC3H, SiC4H and SiC5H, and they present data and theoretical arguments to back that hypothesis.
NASA's Opportunity Mars rover, which landed on the Red Planet in 2004, now holds the off-Earth roving distance record after accruing 25 miles (40 kilometers) of driving. The previous record was held by the Soviet Union's Lunokhod 2 rover.
A team of international researchers has discovered a new type of cool burning flames that could lead to cleaner, more efficient engines for cars. The discovery was made during a series of experiments on the International Space Station.
A recent study shows that the emission is dominated by the local hot bubble of gas - 1 million degrees - with, at most, 40 percent of emission originating within the solar system. The findings should put to rest the disagreement about the origin of the X-ray emission and confirm the existence of the local hot bubble.
Astronomers using the Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before. Created using observations from Hubble's Frontier Fields observing programme, the map shows the amount and distribution of mass within MCS J0416.1-2403, a massive galaxy cluster found to be 160 trillion times the mass of the Sun.
In 2012, the Voyager mission team announced that the Voyager 1 spacecraft had passed into interstellar space, traveling further from Earth than any other manmade object. But, in the nearly two years since that historic announcement, and despite subsequent observations backing it up, uncertainty about whether Voyager 1 really crossed the threshold continues.
