Solar System

Once you've sent the first space probe to Pluto, what do you do for an encore? As NASA’s New Horizons spacecraft races to its encounter with the dwarf planet next year, the Hubble Space Telescope Time Allocation Committee have given its recommendation that the Hubble be used to find the Horizons’ next destination in the outer reaches of the Solar System.  Read More

The European Space Agency's (ESA) Rosetta spacecraft, which back in January awoke from 957 days hibernation on its way to rendezvous with comet 67P/Churyumov-Gerasimenko, has now started its first instrument observations. Included in these instruments are three NASA science packages; MIRO, ALICE, and IES, all of which have started sending science data back to Earth.  Read More

Data collected from observations recorded by NASA's Cassini mission has been used to propose ways to better understand the atmospheres of exoplanets. By studying the light of sunsets on Saturn’s satellite, Titan, scientists have shown how spectra are subtly altered when passing through a hazy atmosphere, thereby giving a greater insight into interpreting the spectral readings of the atmosphere of these distant worlds.  Read More

Large, fresh crater surrounded by smaller craters (Image: NASA)

There are millions of impact craters all over the Solar System, but direct evidence of the massive collisions that form them is very hard to come by – and therefore very valuable. While carrying out its routine monitoring of the weather on the Red Planet, the Mars Color Imager (MARCI) on NASA’s Mars Reconnaissance Orbiter (MRO) has inadvertently snapped before and after images of the largest fresh meteor impact crater found anywhere in the Solar System.  Read More

On its way to rendezvous with comet 67P/Churyumov-Gerasimenko (67P, for short), the European Space Agency's (ESA's) Rosetta spacecraft has spied its approaching target and the coma – the "halo" made primarily out of ice and dust that gives the comet its fuzzy appearance – that is developing around its nucleus. At more than 600 million km (373 million miles) from the Sun, the opportunity to observe the early onset of coma production at such distances promises to add much to our knowledge of the life-cycle of a comet as it wends its way around the solar system.  Read More

Researchers at the University of Texas have identified the Sun's long lost sibling (Image:...

Researchers at the University of Texas have identified a star that formed in the same star cluster as our Sun. Dubbed HD 162826, the star is 15 percent more massive than the Sun and resides 110 light-years away. It's hoped the discovery of this "sibling" will help us understand more about where and how the solar system originated, and might also point us to the best candidates for finding extraterrestrial life.  Read More

Artist's impressionof Beta Pictoris b

According to NASA, 1,703 planets orbiting 1,033 stars have been found so far, but very little is known about these planets beyond some deductions based on their orbits. That veil is lifting though, as demonstrated by Dutch astronomers who have for the first time measured the length of an exoplanet’s day. Using the European Southern Observatory’s Very Large Telescope (VLT) in Chile’s Atacama desert, the team has learned that the young extrasolar gas giant Beta Pictoris b has an eight-hour day and spins faster than any planet in the Solar System.  Read More

JPL scientists say Ganymede may be built like a club sandwich

In a combination of the astronomical and the culinary, scientists at NASA’s Jet Propulsion Laboratory (JPL) say that Jupiter’s largest moon, Ganymede, may not have a single large ocean, but instead may be built like a club sandwich with alternating layers of ice and water. The claim is based on computer models of how salt water acts under the high pressures that may exist beneath Ganymede’s global ice pack, and may improve the chances of finding life elsewhere in the Solar System.  Read More

Scientists from the Carnegie Institution for Science and the Gemini Observatory have reported the existence of a new member of our solar system. The distant dwarf planet, dubbed 2012 VP113, is believed to be one of thousands of distant objects that make up the hypothesized "inner Oort cloud."  Read More

Planet X is a hypothetical star or planet, theorized to be responsible for Earth's mass ex...

A study of data captured by NASA's Wide-Field Infrared Survey Explorer (WISE) satellite has disproved the existence of the hypothesized large celestial body, dubbed "Planet X." The planet or companion star was, some believed, responsible for the periodic mass extinctions that have taken place in Earth's past.  Read More
