Houston - It may seem like the plot of a sci-fi disaster movie, but NASA scientists have given serious consideration of how the Earth should defend itself against an asteroid should such a space rock be on a collision course with our planet.

X-ray mystery surrounds Pluto

Houston - The dwarf planet Pluto continues to tantalize. This follows news that stream of photons have been detected streaming from the planet and into space. The mystery is the planet has no obvious way of making these high-energy photons.

Houston - The Cassini probe, investigating Saturn, has detected a strange swirling structure, hexagonal in shape, at the north pole of the planet. The structure appears to regularly change color.

More moons detected orbiting Uranus

Houston - The number of moons around Uranus is a matter of scientific debate within the astronomy community. Despite the Voyager probe visiting the planet three decades ago, data collected is still being discussed.

Clouds spotted swirling around Pluto

Despite the downgrading of Pluto from a planet (and the ninth in the solar system) to a dwarf planet, much about the far-flung celestial object remains a mystery. A new puzzle involves the presence of clouds.

Essential Science: Did Jupiter wander away from the Sun?

Astronomers have long wondered why there are no planets closer to the Sun than Mercury. To have planets closer is common with many stars. The answer might be due to Jupiter having once been located closer to our star, suggests a new theory.

NASA Dawn mission reveals dwarf planet Ceres with crystal clarity

Pasadena - The latest images of Ceres, taken by NASA’s Dawn spacecraft, show sections of this mysterious dwarf planet in breathtaking detail.

Data from Pluto mission expected to keep arriving for 16 months

Laurel - The universe itself may be billions of years old, but that doesn't mean all of its components were created at the same time.

Martian meteorites provide intriguing hints of life on Mars

Aberdeen - A further clue in the search for life on Mars has emerged after a team of scientists discovered traces of methane in Martian meteorites.

What you need to know about this breakthrough treatment of arthritis

British scientists have hailed the results of a new, experimental stem cell treatment for osteoarthritis as "astonishing."

When Mars had an ocean

Garching Bei M - Mars once hosted an ocean containing more water than the Arctic ocean. Not only that but this primitive Martian Sea covered a greater proportion of Mars’ surface than the Atlantic Ocean does on Earth.

When an iron rain fell on Earth

Not much is known about Earth’s “inner space” —its core — although scientists agree on one thing, much of the core consists of iron. But just how much iron is there remains the subject of debate.

Two unknown Earth-sized planets may be part of Solar System

Scientists tracking the orbits of objects on the extreme edge of our solar system believe that there is a good chance that two planets, at least as large as Earth may exist out there.

Dwarf planet is possible new source of life in our solar system

A potential new source of alien life in our own solar system will be explored by a NASA probe in March 2015. Scientists think that the so-called "dwarf planet," Ceres, could have the right conditions for life to exist and may even be habitable for humans.

NASA's Voyager 1 is riding a huge cosmic tsunami

NASA's Voyager 1 spacecraft, the first and only object made by humanity to reach interstellar space is still riding a cosmic tsunami it hit in February, 2014.

NASA announces live coverage of European comet landing

Pasadena - NASA television will provide live coverage of the European Space Agency’s comet lander mission scheduled to touchdown on comet 67P/Churyumov-Gerasimenko on Wednesday, Nov.12.

Saturn’s weird wobbly moon, Mimas

Ithaca - Saturn’s moon Mimas is already an oddity, being the most cratered object in the Solar System and likened to the Death Star of Star Wars fame. But new research this week points to Mimas being even weirder than previously thought.

Kupalo Crater is one of the youngest craters on Ceres. The crater has bright material exposed on its rim and walls, which could be salts. Its flat floor likely formed from impact melt and debris. Kupalo, which measures 16 miles (26 kilometers) across and is located at southern mid-latitudes, is named for the Slavic god of vegetation and harvest.

An artist’s impression showing how Mars may have looked about 4 billion years ago. The young planet would have had enough water to cover its entire surface in a liquid layer about 140 metres deep. More likely, however, the liquid would have pooled forming an ocean spanning almost half of Mars' northern hemisphere, in some regions reaching depths greater than 1.6 kilometers.

A projection of the radar data of Venus collected in 2012. Striking surface features -- like mountains and ridges -- are easily seen. The black diagonal band at the center represents areas too close to the Doppler “equator” to obtain well-resolved image data.

An artist's concept of the Oort cloud. Note that the distance scale is logarithmic. Compared to the size of planetary orbits, the Oort cloud is very far away. If the Sun passed within 2 light years of another sun-like star, the stars' Oort clouds would overlap and their comets would intermingle.
