Now superheated by greenhouse gases, Venus' climate was once more similar to Earth's, with a shallow ocean's worth of water. It may even have subduction zones like Earth, areas where the planet's crust sinks back into rock closer to the core of the planet.


The brightly lit capital city of Bucharest, Romania with a population of almost 1.9 million, is pictured from the International Space Station as it orbited 263 miles above the eastern European nation.


Curiosity won't be NASA's only active Mars rover for much longer.


Our Milky Way galaxy has an elegant spiral shape with long arms filled with stars, but exactly how it took this form has long puzzled scientists. New observations of another galaxy are shedding light on how spiral-shaped galaxies like our own get their iconic shape.


New time-lapse videos of Earth's glaciers and ice sheets as seen from space - some spanning nearly 50 years - are providing scientists with new insights into how the planet's frozen regions are changing.


Traveling approximately 260 miles over the Yellow Sea east of Shanghai, the automated Russian Progress 74 cargo resupply spacecraft docked at 5:35 a.m. EST to the Pirs docking compartment on the Russian segment of the International Space Station.


A new instrument with its eye on the Moon is taking off aboard a high-altitude NASA plane to measure the Moon's brightness and eventually help Earth observing sensors make more accurate measurements.


The Pioneer 10 and 11 and Voyager 1 and 2 spacecraft, launched in the 1970s, are heading out of the solar system.


Members of a polar research expedition have provided researchers from Charité - Universitätsmedizin Berlin and the Max Planck Institute for Human Development with an opportunity to study the effects of social isolation and extreme environmental conditions on the human brain.


Some of the most dramatic events in the universe occur when certain stars die -- and explode catastrophically in the process.


Engineers at NASA's Marshall Space Flight Center in Huntsville, Alabama, on Dec. 5 deliberately pushed the world's largest rocket fuel tank beyond its design limits to really understand its breaking point.


NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station.


The Copernicus Sentinel-1 mission takes us over part of the Brazilian state of Mato Grosso deep in the Amazon interior.


The SpaceX Dragon resupply ship is on its way to the International Space Station packed with science and supplies for the Expedition 61 crew.


ESA astronaut Luca Parmitano, attached to the Canadarm2 robotic arm, carries the new thermal pump system that was installed on the Alpha Magnetic Spectrometer (AMS).


Shortly after NASA's OSIRIS-REx spacecraft arrived at asteroid Bennu, an unexpected discovery by the mission's science team revealed that the asteroid could be active, or consistently discharging particles into space.


NASA provided analyses of Typhoon Kammuri's heavy rainfall on its track through the Northwestern Pacific Ocean using the Global Precipitation Measurement mission or GPM core satellite.


NASA's OSIRIS-REx mission is just days away from selecting the site where the spacecraft will snag a sample from asteroid Bennu.


Outbursts of energetic particles that hurtle out from the sun and can disrupt space communications may be even more varied and numerous than previously thought, according to results from the closest-ever flyby of the sun.


NASA-NOAA's Suomi NPP satellite passed over the South China Sea and provided forecasters with a visible image of Tropical Storm Kammuri on Dec. 4.


The first evidence of a giant planet orbiting a dead white dwarf star has been found in the form of a disc of gas formed from its evaporating atmosphere.


The Expedition 61 crew aboard the International Space Station is focusing on a pair of upcoming cargo deliveries after completing a spacewalk on Monday.


This is the most complete and detailed observation to date of the formation and dissipation of a naturally-occurring comet outburst. The team members reported their results in the November 22 issue of The Astrophysical Journal Letters.


Computers can learn to find solar flares and other events in vast streams of solar images and help NOAA forecasters issue timely alerts, according to a new study.


A surprising analysis of the composition of gas giant exoplanets and their host stars shows that there isn't a strong correlation between their compositions when it comes to elements heavier than hydrogen and helium, according to new work led by Carnegie's Johanna Teske and published in the Astronomical Journal.


Imagery from NASA-NOAA's Suomi NPP satellite showed that a tropical depression in the Arabian Sea has consolidated and organized despite facing wind shear. Tropical Depression 06A is now Tropical Cyclone 06A.


Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) and NASA Flight Engineer Andrew Morgan concluded their spacewalk at 12:33 p.m. EST.


Vikram impact point and associated debris field. Green dots indicate spacecraft debris (confirmed or likely).


Some galaxies are closer friends than others. While many live their own separate, solitary lives, others stray a little too close to a near neighbor and take their friendship even deeper.


NASA-NOAA's Suomi NPP or S-NPP satellite passed over the Philippine Sea in the Northwestern Pacific Ocean and found Typhoon Kammuri's eye obscured.


Do you want to fly into space? Do you know someone who does? If so then this book is worth reading. "See You In Orbit? Our Dream of Spaceflight" by Alan Ladwig presents a comprehensive look by a space insider into the history of what space travel means to people.


ESA astronaut Luca Parmitano has made robotics history, reaching out from the International Space Station in orbit around Earth at 8 km/s, to control an Earth-based rover, equipped with an advanced gripper possessing the equivalent mobility and dexterity of a human hand.


Since the saltiness of ocean surface waters is a key variable in the climate system, understanding how this changes is important to understanding climate change.
