The European Space Agency is set to unveil a three-dimensional map of a billion stars in our galaxy that is 1,000 times more complete than anything existing today.
The hydrogen ions travel at 99.999,999,1 per cent of the speed of light. Their time slows down by a factor of 27,777,778. One second for one of these protons is about 11 months for us.
New work from a team led by Carnegie’s Eduardo Bañados has discovered 63 new quasars from when the universe was only a billion years old.
As far as stars go, these two are rather close together to have such massive, Jupiter-sized planets orbiting them. The planets and their stars were found 154 light-years away in the constellation Libra.
Anchored to a carrier aircraft, Virgin SpaceShip Unity takes to the skies in Mojave, Calif.
Computer simulations of a spherical collection of stars known as 'NGC 6101' reveal that it contains hundreds of black holes, until now thought impossible.
Humanity is about to deepen its understanding of Earth's winds. The European Space Agency has secured a rocket launch deal for its wind-tracking Aeolus satellite, which is now expected to enter orbit before the end of 2017.
The Global Seed Vault is a vast storehouse far north of the Arctic Circle. In it are half a billion seeds from around the world. The vault is meant to safeguard humanity against losing vital food stocks to extinction, natural disaster, nuclear war or climate change.
Scientists believe Venus was once Earth-like. How is this possible and what caused the planet to turn toxic?
Research by Rice University Earth scientists suggests that virtually all of Earth’s life-giving carbon could have come from a collision about 4.4 billion years ago between Earth and an embryonic planet similar to Mercury.
NASA's Juno spacecraft has sent back the first-ever images of Jupiter's north pole, taken during the spacecraft's first flyby of the planet with its instruments switched on.
OSIRIS-REx will bring back specimens for researchers to interrogate inside high-tech labs around the world, seeking clues about the origin of life, water and the planets themselves. The results could be skewed by an unexpected microbe or spore from planet Earth.
An international team of astronomers led by Italian Claudio Maccone has published the first preliminary data on the signal, which comes from a star 95 light years away.
One year ago, six volunteers entered a 36-by-20 foot dome, located near a barren volcano in Hawaii, to simulate what living conditions would be like on Mars. Today they re-emerged from their year-long isolation.
The astronauts who will one day be the first to walk on Mars are likely middle school students today. A virtual reality tour of Mars is done on a retrofitted school bus outside the Denver Museum of Nature, USA
