Titan's siblings must be jealous. While most of Saturn's moons display their ancient faces pockmarked by thousands of craters, Titan - Saturn's largest moon - may look much younger than it really is because its craters are getting erased. Dunes of exotic, hydrocarbon sand are slowly but steadily filling in its craters.
As part of the first demonstration of laser communication with a satellite at the moon, scientists with NASA's Lunar Reconnaissance Orbiter (LRO) beamed an image of the Mona Lisa to the spacecraft from Earth.
Nearly 200 000 light-years from Earth, the Large Magellanic Cloud, a satellite galaxy of the Milky Way, floats in space, in a long and slow dance around our galaxy. Vast clouds of gas within it slowly collapse to form new stars.
ESA agreed with NASA today to contribute a driving force to the Orion spacecraft planned for launch in 2017. Ultimately, Orion will carry astronauts further into space than ever before using a module based on Europe's Automated Transfer Vehicle technology.
China plans to launch 20 spacecrafts this year, including the country's third lunar probe Chang'e-3 and manned spacecraft Shenzhou-10, China Aerospace Science and Technology Corporation (CASC) announced Wednesday.
NASA's Space Technology Program is looking for visionary advanced concepts. This year's annual call for NASA's Innovative Advanced Concepts Program (NIAC) is seeking proposals for revolutionary concepts with the potential to transform future aerospace missions. Proposed concepts should enable new missions or significantly improve current approaches to achieve aerospace objectives.
An international team of nuclear astrophysicists has shed new light on the explosive stellar events known as novae. The team of scientists measured the nuclear structure of the radioactive neon produced through this process in unprecedented detail.
Galaxies have a voracious appetite for fuel - in this case, fresh gas - but astronomers have had difficulty finding the pristine gas that should be falling onto galaxies. Now, scientists have provided direct empirical evidence for these gas flows using new observations from the Hubble Space Telescope.
If dark energy did not exist, the gravitational pull exerted by matter would slow down the expansion of the universe, but observations have concluded that the opposite is the case.Dark energy is what makes the universe expand in an accelerating way.
