A team of astronomers has identified possibly the coldest, faintest white dwarf star ever detected. This ancient stellar remnant is so cool that its carbon has crystallized, forming - in effect - an Earth-size diamond in space.
Who owns the moon? What kind of valuable resources does Earth's nearest neighbor hold? And how - and when - can we access them? All these questions will be debated today by a panel comprised of scientists, entrepreneurs and policy makers brought together by Google Lunar XPRIZE at the EuroScience Open Forum (ESOF) 2014.
In the nearly 25 years since the launch of the Hubble Space Telescope (HST), astronomers and the public alike have enjoyed ground-breaking views of the cosmos and the suite of scientific discoveries that followed. The successor to HST, the James Webb Telescope should launch in 2018 but will have a comparatively short lifetime.
Astronomers have discovered a bright, mysterious geologic object - where one never existed - on Cassini mission radar images of Ligeia Mare, the second-largest sea on Saturn's moon Titan. Scientifically speaking, this spot is considered a 'transient feature', but the astronomers have playfully dubbed it 'Magic Island'.
An international team of astronomers, using data from several NASA and European Space Agency (ESA) space observatories, has discovered unexpected behavior from the supermassive black hole at the heart of the galaxy NGC 5548, located 244.6 million light-years from Earth. This behavior may provide new insights into how supermassive black holes interact with their host galaxies.
Following a thorough peer-review process, the researchers who previously announced the detection of B-mode polarization in a patch of the microwave sky have published their findings today. Possibly primordial gravitational waves, but galactic dust not ruled out.
They may only be little, but they pack a star-forming punch: new observations from the Hubble Space Telescope show that starbursts in dwarf galaxies played a bigger role than expected in the early history of the Universe.
Costing a fraction of conventional space telescopes and similar in size and weight to a car battery, the satellites are two of six that will work together to shed light on the structures and life stories of some of the brightest stars in the sky, uncovering unique clues as to the origins of our own Sun and Earth.
On June 5th, 2014, the ISS passed over the Table Mountain Observatory in Wrightwood, California, and beamed an HD video to researchers waiting below. Unlike normal data transmissions, which are encoded in radio waves, this one came to Earth on a beam of light.
New research indicates that ultraviolet photons emitted by the sun likely cause H2O molecules on the lunar surface to either quickly desorb or break apart. The fragments of water may remain on the lunar surface, but the presence of useful amounts of water on the sunward side is not likely.
