An astronomical story to close out the year. The most-distant solar system object ever observed has been detected by astronomers. The outer solar system objects is described as a 'far out there' dwarf planet.

Hyabusa2 rovers send back stunning images of Ryugu

On September 21, the Japanese space agency JAXA made history by safely landing two tiny rovers on the rugged terrain of an asteroid. The first images were astounding, simply because they proved the little rovers were working, but check out the new images.

Essential Science: How our Sun went through the 'terrible twos'

Astrophysicists, looking into the early phase of our Sun, have been studying, in conjunction, blue crystals in meteorites. These crystals show that our Sun went through the astronomical equivalent of the 'terrible twos'.

New moon for Jupiter discovered, dubbed 'Oddball'

A dozen new moons orbiting Jupiter have been discovered. This incubuses one dubbed, for the time being at least, called 'Oddball'. The discovery brings the total of Jupiter's moons to 79.

Meet synestia, a new type of planetary object

Astrophysicists are proposing a new type of planetary object which they’ve named a 'synestia'. By this they are referring to a large, rotating, donut-shaped mass of hot, vaporized rock.

Is frost present on the Moon?

Houston - Although it has been studied with regularity and visited several times, the Moon continues to present surprises. It appears that bright areas in craters near the moon's south pole are cold enough to have frost present.

Atmosphere of Jupiter surprisingly 'exotic'

Houston - NASA's Juno mission to Jupiter has delivered first science results and the findings suggest the biggest planet in our solar system is more complex than previously thought.

Most of the Martian atmosphere was lost to space

Mars is much like Earth in many ways and billions of years ago when the Sun was hotter, scientists speculate that Mars could possibly had water and life. One longstanding mystery, in relation to this theory concerns, the Martian atmosphere.

The Sun had no sunspots for two weeks

Reading - Astronomers working for NASA regularly monitor the Sun and note down any unusual patterns. Last month the Solar Dynamics Observatory flagged up something unusual: there were no sunspots for a 15 day period.

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.

Essential Science: Mystery of Mercury’s Great Valley

Mercury has long been regarded as one of the Solar System’s more mysterious planets. Despite decades of observations by astronomers new points of interest appear. The latest is with the planet’s great valley.

Weird blue mass detected in front of the Sun

Houston - NASA has reported an unusual phenomenon: a strange blue mass in front of the Sun. The object was detected by the Stereo satellites, and it appeared to pass across the face of the star.

Water detected on asteroid named Psyche

Houston - Water has been detected water on the largest metallic asteroid in the solar system by a team of NASA scientists. The asteroid is called Psyche and it could become the target of a space mission.

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.

New Horizons: Solar wind stripping away Pluto's atmosphere

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.

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.

NASA's Dawn spacecraft viewed this Cerean crater, which is covered in ridges and steep slopes, called scarps on Dec. 23, 2015. Such likely resulted when the crater partly collapsed during its formation. The curvilinear nature of the scarps resembles those on the floor of Rheasilvia, the giant impact crater on Vesta, which Dawn orbited from 2011 to 2012. The 20-mile-wide (32-kilometer-wide) crater is located just west of the larger, named crater Dantu at northern mid-latitudes on Ceres.
