The southern hemisphere of Mars is home to a crater that contains very well-preserved gullies and debris flow deposits. The geomorphological attributes of these landforms provide evidence that they were formed by the action of liquid water in geologically recent time.Wh
A team of scientists analyzing the coma and tail of Comet Hale-Bopp have published their observations in a landmark paper but what they discovered cannot be explained by the standard model of comets. The scientists analyzed the comet's surprising coma and tail at di
The first solar eclipse of 2014 will occur on April 29. This will be annular solar eclipse – the Moon will be too far away from the Earth to completely cover the Sun resulting in a ring of light around the darkened Moon. This eclipse occurs at the Moon
NASA's Lunar Atmosphere and Dust Environment Explorer, or LADEE, ended its mission last week with a planned impact on the Moon but just before the impact it performed another successful laser communication with ESA's ground station at a stunning s
At a press conference held today at the Seattle Museum of Flight, three prominent astronauts supporting the B612 Foundation presented a visualization of new data showing the surprising frequency at which the Earth is hit by asteroids. The astronauts were guests of
Lyrid meteor shower, considered to be the oldest of meteor showers, is an average shower usually producing about 20 meteors per hour at its peak. This shower runs annually from April 16 – 25 and its peak this year is predicted to occur near 18:00 UTC on April
European Space Agency (ESA) launched Sentinel-1A satellite on April 3, 2014 which opened a new page in the implementation of Copernicus, the largest civil Earth observation programme ever conceived and the second EU flagship space initia
Astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" – the range of distance from a star where liquid water might pool on the surface of an orbiting planet and could possibly sustain life. The planet, called
Solar activity was at low levels during last 24 hours, however, that might change today and in the days ahead. Active Region 2036 exhibited rapid growth over the last few days and is now almost directly facing our planet. Earth directed eruption
NASA's Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may also provide clues to the formation of the planet's known moons.Images taken with Cassini's narrow angle camera on Apr
