Astronomers have detected an atmosphere on another Earth-like planet. This marks the first detection of an atmosphere around an Earth-like planet other than Earth itself, and thus is a significant step on the path towards the detection of life outside our Solar System.
On April 3, 2017, as Jupiter made its nearest approach to Earth in a year, NASA's Hubble Space Telescope viewed the solar system's largest planet in all of its up-close glory.
A major discovery has been made on the formation of icy bodies within the Kuiper Belt, unlocking unique evidence that Neptune's movement during early planet formation was a 'smooth and calm' journey.
New research has uncovered a mechanism, similar to one that occurs on Earth, which may allow new insights into forecasting space weather and activity on the sun.
A mysterious flash of X-rays has been discovered by NASA's Chandra X-ray Observatory in the deepest X-ray image ever obtained. This source likely comes from some sort of destructive event, but it may be of a variety that scientists have never seen before.
A young-looking volcanic caldera on the Moon has been interpreted by some as evidence of relatively recent lunar volcanic activity, but new research suggests it's not so young after all.
To time how long it takes a pulse of laser light to travel from space to Earth and back, you need a really good stopwatch -- one that can measure within a fraction of a billionth of a second. That kind of timer is exactly what engineers have built at NASA's Goddard Space Flight Center in Greenbelt, Maryland, for the Ice, Cloud and land Elevation Satellite-2.
Experiments suggest the particles that cover the surface of Saturn's moon, Titan, are 'electrically charged.' When the wind blows hard enough, Titan's non-silicate granules get kicked up and start to hop in a motion. As they collide, they become frictionally charged, like a balloon rubbing against your hair, and clump together in a way not observed for sand dune grains on Earth -- they become resistant to further motion.
The same kind of large-scale planetary waves that meander through the atmosphere high above Earth's surface may also exist on the sun, according to a new study.
NASA's Van Allen Probes uncover new phenomena in our near-Earth environment with their unique double orbit. Recently, the spacecraft were in just the right place, at just the right time, to catch an event caused by the fallout of a geomagnetic storm as it happened.
A molecule found in car engine exhaust fumes that is thought to have contributed to the origin of life on Earth has made astronomers heavily underestimate the amount of stars that were forming in the early Universe, a study has found. That molecule is called polycyclic aromatic hydrocarbon. On Earth it is also found in coal and tar. In space, it is a component of dust.
Satellites have been mapping the upper part of the Earth magnetic field by collecting data for three years and found some amazing features about the Earth’s crust. The result is the release of highest resolution map of this field seen from space to date. This ‘lithospheric magnetic field’ is very weak and therefore difficult to detect and map from space. But with the Swarm satellites it has been possible.
Images returned from the European Space Agency's Rosetta mission indicate the surface of comet 67P/Churyumov-Gerasimenko was a very active place during its most recent trip through the solar system, says a new study.
Changes that the Rosetta spacecraft discovered on the surface of Comet 67P/Churyumov-Gerasimenko, including the collapse of entire cliffs, were likely driven by seasonal events, according to a new study.
Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity, about 50 million years ago. The last volcanic activity there ceased about 50 million years ago -- around the time of Earth's Cretaceous-Paleogene extinction, when large numbers of our planet's plant and animal species (including dinosaurs) went extinct.
Researchers have developed a model that suggests that debris that was pushed into space from an asteroid or other body slamming into Mars around 4.3 billion years ago and alternates between becoming a planetary ring and clumping up to form a moon.
The inner Van Allen belt has less radiation than previously believed, according to a recent study. Observations from NASA's Van Allen probes show the fastest, most energetic electrons in the inner radiation belt are actually much rarer and harder to find than scientists expected. This is good news for spacecraft that are orbiting in the region and can be damaged by high levels of radiation.
Astronomers measured the light produced when a sun-like star wandered too close to a 3-million-solar-mass black hole similar to the one at the center of our own galaxy.
Hubble caught a cross-section of NGC 1448, a spiral galaxy located about 50 million light-years from Earth.
Eruptions on the Sun's surface not only send bursts of energetic particles into the Earth's atmosphere causing disturbances in our planet's magnetic field, they can also strangely decrease the number of free electrons over large areas in the polar region of the ionosphere, new research concludes.
