The first Earth-sized exoplanet orbiting within the habitable zone of another star has been...
Geologists who analyzed 40 meteorites that fell to Earth from Mars have unlocked secrets of the...
The soil on Mars may be suitable for cultivating food crops. In a unique pilot experiment, a scientist tested the growth of 14 plant varieties on artificial Mars soil over 50 days. To his surprise, the plants grew well; some even blossomed.
Imagine you are an astronaut on the ISS and a fleck of dust gets in your eye. How do you wash it out? Engineers came up with the idea seen in this picture.
The ISS is about to get some fresh groceries and material for an urgent repair job. An unmanned SpaceX rocket is on the launch pad at Cape Canaveral even though a critical backup computer failed outside the space station Friday, prompting safety concerns.
An experiment, which will test how plant cells sense and respond to different levels of gravity, is scheduled to launch aboard the SpaceX Falcon 9 rocket from Cape Canaveral on Monday.
An Apollo 11 lunar surface checklist sheet was among the coveted items— sold at an auction of space exploration artifacts— that fetched for more than the pre-sale estimate.
Next Tuesday morning, April 15, 2014, the moon will be eclipsed by Earth's shadow. This total lunar eclipse will be visible across the Western Hemisphere.
Reconstructing the history of our Galaxy has just become a whole lot easier, thanks to a team of international astronomers. By examining both the light and sound waves from stars, they developed a more precise way to deduce the ages of stars and pinpoint when the Galaxy’s big events happened.
Everything from American and Russian spacesuits to a moon dust-covered strap from the Apollo 12 mission will be available to space history buffs at auction in New York City this week.
The ESA says it has successfully launched the first in a series of satellites that will form the nucleus of its new Copernicus monitoring system, which is aimed at providing better and quicker information about natural disasters and other catastrophes.
Using satellite imagery to monitor which volcanoes are deforming provides statistical evidence of their eruption potential, according to a new study. ESA’s Sentinel satellite, launched this week, should allow scientists to test this link in greater detail and eventually develop a forecast system for all volcanoes, including those that are remote and inaccessible.
Scientists have uncovered a vast ocean beneath the icy surface of Saturn's little moon, Enceladus. Researchers made the discovery using Cassini, a NASA-European spacecraft still exploring Saturn and its rings 17 years after its launch from Cape Canaveral.
After insisting that space relations wouldn't be altered by earthly politics, NASA announced it was severing ties with Russia except for the International Space Station.
Health and ethics experts have issued principles and guidelines to aid NASA in decision-making for longer, higher-risk human spaceflights.
An international team of planetary scientists determined that the Moon formed nearly 100 million years after the start of the solar system. This conclusion is based on measurements from the interior of the Earth combined with computer simulations of the protoplanetary disk from which the Earth and other terrestrial planets formed.
The amount of water present in the moon may have been overestimated by scientists studying the mineral apatite, according to a team who created a computer model to accurately predict how apatite would have crystallized from cooling bodies of lunar magma early in the moon's history.
Mars, the protoplanet Vesta and the dwarf planet Ceres reach opposition this month, wherein they are directly opposite the sun. Also in April, a lunar eclipse will be visible in North and South America and the Pacific and the Lyrid meteor shower will peak.
Beginning this year, NASA will launch four satellites equipped with technology to study the microphysics of magnetic reconnection— the fundamental process that happens during such solar atmosphere events as solar flares and coronal mass ejections.
Perhaps the original spiral nebula, this large galaxy with well-defined spiral structure is cataloged as NGC 5194. Its spiral arms and dust lanes clearly sweep in front of its companion galaxy, NGC 5195.
Researchers have developed a method for analyzing the pressure experienced by tiny samples of organic material that may have been ejected from dying stars before making a long journey through the cosmos.
Earth and Mars are converging for a close encounter. As March gives way to April, the distance between the two planets is shrinking by about 300 km every minute.
The European Mars rover, unveiled at a "Mars Yard" testing ground in Britain this week, is designed to drill beneath the surface of the Red Planet searching for signs of life.
Scientists have for the first time witnessed the mechanism behind explosive energy releases in the Sun’s atmosphere, confirming new theories about how solar flares are created.
It has been known that many hot white dwarfs atmospheres, essentially of pure hydrogen or pure helium, are contaminated by other elements– like carbon, silicon and iron. Now, after decades of questions, researchers have learned the origins of these elements.
NASA and the Japan Aerospace Exploration Agency have released the first images captured by their newest Earth-observing satellite, the Global Precipitation Measurement Core Observatory, which launched into space Feb. 27.
A software glitch on a Russian spacecraft heading to the International Space Station has delayed the arrival of three astronauts, including an American. NASA says the crew was in no danger, and the U.S.-Russia space partnership was strong despite tensions over Ukraine.
