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
Dragonfly 44, as it has been named, is roughly the same size as our Milky Way but with far fewer stars. Rather, the galaxy appears to be composed largely of dark matter, which does not emit light or interact with electromagnetic radiation.
New stars are formed in the undulating clouds of M8, also commonly referred to as the Lagoon Nebula, situated some 5,000 light years from our planet.
A new planet that bears striking similarities to our own planet prompts remarkable inroad into the study of space. This also brings a new area to search for the possibility of extraterrestrial life.
New research shows that GJ 1132b might possess a thin, oxygen atmosphere — but no life due to its extreme heat.
Two NASA astronauts successfully installed a new parking spot at the International Space Station today, marking a key step toward accommodating new commercial space taxis that arrive at the orbiting lab.
Earlier in its history, the second planet from the sun may have had a liquid water ocean and temperatures suitable for life, a new study shows.
Saturn's exotic moon Titan, with its thick atmosphere and large, methane lakes, continues to beguile planetary scientists. Now, using data collected by an altimeter aboard NASA's Cassini spacecraft, scientists have found liquid methane flowing through deep gorges on the moon's surface.
An international team of astronomers reports that they were able to achieve four times better precision in measurements of how the universe's visible matter is clustered together by studying the empty spaces in between.
