Provided by Richard Hook, ESO Biggest census ever of exocomets around Beta Pictoris Beta Pictoris is a young star located about 63 light-years from the Sun. It is only about 20 million years old and is surrounded by a huge disc of material — a very active young planetary system where gas and dust are produced by the evaporation of comets and the collisions of asteroids. Flavien Kiefer (IAP/CNRS/UPMC), lead author of the new study sets the scene: "Beta Pictoris is a very exciting...

GREENBELT, Md., Oct. 22, 2014 /PRNewswire-USNewswire/ -- New maps of Saturn's moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The pair of patches was spotted by a NASA-led international team of researchers...

Brett Smith for redOrbit.com - Your Universe Online On Earth, frost is known as a thin, delicate icy covering of frozen water that forms when temperatures dip below a certain point. However, according to a report presented at the Geological Society of America meeting in Vancouver on Monday, frost on Venus may be much different – possibly made not of frozen water, but from heavy metals like cadmium and mercury. The new report is actually based on old data from the Magellan probe,...

Provided by Dr. Tony Phillips, Science@NASA Waking up before sunrise is a good way to get a head start on the day. On Oct. 21st, waking up before sunrise could stop you in your tracks. Blame Halley’s Comet. Every year in mid-to-late October, Earth passes through a stream of dusty debris from Comet Halley, and the pre-dawn sky can light up with a pretty display of shooting stars. "We expect to see about 20 meteors per hour when the shower peaks on Tuesday morning, Oct 21st," says...

Brett Smith for redOrbit.com - Your Universe Online Saturn’s moon Mimas is known for a resemblance to the Death Star from Star Wars, but that’s not the moon’s most unique attribute: The moon actually wobbles significantly in its orbit around Saturn. In a new study based on data from NASA’s Cassini probe, researchers have laid out two theories on why Mimas wobbles so much. The first theory is that the moon has a liquid water ocean underneath its icy surface. The second theory is...

Provided by JHU/APL NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft has provided the first optical images of ice and other frozen volatile materials within permanently shadowed craters near Mercury's north pole. The images not only reveal the morphology of the frozen volatiles, but they also provide insight into when the ices were trapped and how they've evolved, according to an article published October 15 in the journal, Geology. Two decades...

Provided by Preston Dyches, NASA Jet Propulsion Laboratory Static electricity is known to play an important role on Earth's airless, dusty moon, but evidence of static charge building up on other objects in the solar system has been elusive until now. A new analysis of data from NASA's Cassini mission has revealed that, during a 2005 flyby of Saturn's moon Hyperion, the spacecraft was briefly bathed in a beam of electrons coming from the moon's electrostatically charged surface. The...

Provided by Pam Frost Gorder, The Ohio State University Our view of other solar systems just got a little more familiar, with the discovery of a planet 25,000 light-years away that resembles our own Uranus. Astronomers have discovered hundreds of planets around the Milky Way, including rocky planets similar to Earth and gas planets similar to Jupiter. But there is a third type of planet in our solar system — part gas, part ice — and this is the first time anyone has spotted a twin...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...
