NASA scientists want Pluto to become a planet again

A group of NASA scientists want Pluto’s status as a planet restored. Eleven years ago, the ninth planet in the solar system was downgraded to that of a dwarf planet. To scientists who are working on journeys to Pluto, that is simply not good enough.

Essential Science: What would landing on Pluto be like?

This week’s Essential Science takes a step into speculative science (fiction) and discusses some new research that wonders what landing on the surface of the dwarf planet Pluto would be like.

The moon is older than previously thought

The moon is probably 40 to 140 million years older than previously thought. This is based on new analysis of samples brought back from Apollo 14 which have been subjected to more sophisticated testing.

Scientists develop new theory on how Earth's moon was formed

A new theory about how Earth’s moon was formed has been advanced. It speculates that several extra-terrestrial objects struck Earth creating a series of small moons or moonlets. These moonlets gradually merged to form the moon we see today.

Sun spins faster on the outside than on the inside

Despite being relatively close to Earth and a well-studied phenomenon there is still much to learn about the Sun. New research by international astronomers has helped to make an important new discovery about our closest star.

'Death Star' that eats planets discovered

Analysis of the star located 300 light years from Earth showed materials in the body indicating the star has swallowed some of the planets orbiting it. Similar to our Sun, the star provides clues about our own solar system and what is likely to happen.

Scientists warn Earth to prepare for killer asteroid

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.

Strange swirling hexagonal structure on Saturn spotted

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.

Solar system is much bigger than we thought

The size of the solar system, that’s Earth and the planets that orbit the Sun, is much bigger than previous calculations indicated.

Mars once had many moons

Mars, the red planet that is most like Earth in our solar system, once had several moons. It is thought the satellites now form part of the asteroid belt.

NASA detects new moon in our solar system

Houston - A new moon around a dwarf planet has been detected beyond the reaches of Pluto. This has been detected by NASA’s New Horizons spacecraft.

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.

Illustration showing the scale and comparative brightness of Pluto’s small satellites. Pluto’s binary companion, Charon, is at the bottom for scale. The image illustrates that two of the moons are highly oblate and that the reflectivity among the moons varies from dark charcoal to the brightness of sand.Hubble can't resolve surface features on the moons so textures are purely for illustration purposes.

An artist’s impression shows how Mars may have looked about four billion years ago. The young planet Mars would have had enough water to cover its entire surface in a liquid layer about 140 metres deep, but it is more likely that the liquid would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 kilometers.
