With the demotion of Pluto back in 2006, the decision to rewrite the definition of a planet has since been questioned. With the discoveries of massive objects outside our Solar System, including Jupiter-like giant planets, the line has become more blurred.
A lump of space rock some 6.9 million kilometres (4.3 million miles) away has been revealed to be an asteroid that’s quite rare in our Solar System, according to detailed images taken by the Arecibo Observatory. To date, the asteroids that we have found seem to be comprised of smaller rocks held loosely by gravity.
An international team of scientists has found evidence of a series of massive supernova explosions near our Solar System, which showered the Earth with radioactive debris. The scientists found radioactive iron-60 in sediment and crust samples taken from the Pacific, Atlantic and Indian Oceans.
Image credit: NASA/ESA/L. Hustak (STScI) Using NASA’s Hubble and Kepler space telescopes, astronomers have uncovered tantalising evidence for what could be the first discovery of a moon orbiting a planet outside our solar system. This moon candidate, which is 8,000 light years from Earth in the Cygnus constellation, orbits a gas-giant planet ...
The Solar System over four billion years ago was mayhem, as it contained copious amount of protoplanets and leftover debris. Image credit: NASA/JPL-Caltech Roughly 200 years ago, a French mathematician and physicist by the name of Pierre-Simon Laplace discovered that the Moon’s equatorial bulge was too big – by the order of twenty times ...
00:00. This incredible video, named “Outer Space” by its creator Sander van den Berg, is a cosmic montage of real-life NASA photos of the Saturn and Jupiter systems. It uses images taken by both the Voyager and Cassini spacecraft from their missions through the Solar System. In the amazing video you can see the rings of the two largest ...
The mystery of the ‘bright nights’ has been solved. by Lee Cavendish, 22 June 2017. The previously unexplained phenomena are supposedly caused by waves converging in the upper atmosphere. 0. 0. comments. Airglow can occur in a variety of colours, as shown in this image, and they can occur in different circumstances. Image credit: NASA.
Our deepest condolences go out to his friends and family. The following is an extract from our full interview with him in issue 4 of All About Space magazine. Sir Patrick Moore spent decades observing the Solar System, and there were many things out there that interested him. “I’m fascinated by Saturn, and the lakes of Titan are very ...
Solar System It wasn’t just an asteroid that killed the dinosaurs, there was also a tsunami This catastrophic event wiped out 76 percent of all life on Earth 66 million years ago
This would be a valuable data point in itself, suggesting that the population of interstellar objects in our solar system is much smaller than scientists had thought. Putting it out there The main goal of the new study, which Siraj and Loeb just submitted to the journal Acta Astronautica , is to get the idea out and see if it generates any ...
