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

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

Since Earth is the only known inhabited planet and we happen to live here, it’s only natural to regard it as the ideal place for life to exist, and to assume that another life-bearing planet would be fairly similar. However, that is not the opinion of scientists René Heller and John Armstrong who contend that there might be a planet even more suitable for life than Earth 4.3 light years away orbiting the star Alpha Centauri B.  Read More

In mid-2015, the asteroid probe Dawn is scheduled to establish orbit around Ceres, the only dwarf planet in the inner Solar System, as well as the largest asteroid, to begin roughly six months of close-up observation. The level of interest in this mission has significantly increased with the detection by the ESA's Herschel space observatory of plumes of water vapor being exuded from Ceres' surface from a pair of local sources.  Read More

NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) may have only come back online last September after a 31-month hibernation, but it’s already producing results. According to the space agency, the unmanned spacecraft discovered a never-before-seen asteroid on December 29 – the first discovery of its new mission to seek out potentially hazardous near-Earth objects (NEOs).  Read More

NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) has sent back the first test images from its 16-in (40-cm) telescope and infrared cameras as it is prepared for its new mission. Intended to seek out potentially dangerous asteroids and help in selecting a near-Earth object as part of the space agency’s asteroid retrieval effort, NASA says NEOWISE will be a powerful tool for discovering, cataloging and understanding the asteroids in the inner Solar System.  Read More

P/2013 P5 is an asteroid with six comet-like tails (Image: NASA, ESA, and D. Jewitt)

In the old days, astronomy was simple – comets had tails and asteroids didn’t. Now, as if to not only disprove such established views, but drive the point home, NASA's Hubble Space Telescope took images in September of an asteroid called P/2013 P5 that has not one, but six comet-like tails.  Read More

Sometimes great mysteries hang right over our heads. We’re so used to looking up and seeing the “Man in the Moon” that we often don’t realize that those familiar dark areas on the face of our nearest neighbor are part of a centuries old question that has yet to be answered. Many hypotheses have been put forward and now data from NASA's twin Gravity Recovery and Interior Laboratory (GRAIL) lunar orbiters has provided new insights into how the surface of the Moon formed and how its distinctive “seas” came to be.  Read More

After a journey of 36 years, NASA has announced that the Voyager 1 space probe officially left the Solar System on August 25, 2012. Based on new analysis of data sent by by the unmanned spacecraft, the space agency has declared that it is now in the first man-made object to travel into interstellar space, 12 billion miles (19 billion km) from the Sun.  Read More

In many countries around the world the supply of electricity and clean water is often sporadic and of poor quality. Consulting and design company NOS is looking to address this problem with PhotoFlow, a two-in-one concept design that combines solar power generation with water collection and storage.  Read More
