At a Glance Researchers in Japan suspect silicon is the likely mystery element in the Earth's inner core.They believe silicon makes up about 5 percent of the inner core. As a solution to one of the deepest secrets about our planet, Japanese scientists say silicon is likely the mysteryelement in the Earth's inner core. It has been widely believed that the planet’s center is made up of about 85 percent iron, 10 percent nickel and the remaining 5 percent ,...

While exploring Mars, NASA’s Curiosity rover came across a what researchers say is a mineral-rich meteorite. The image of the rock, which has been dubbed Ames Knob, was , according to NASA. Results from Curiosity's ChemCam, a laser-firing spectrometer, suggest that ,Space.com reports. , such as a metallic luster and a slightly dimpled texture that may come from regmaglypts, which are indentations commonly seen in meteorites, accordingto Phys.org. The markings occur when softer materials are stripped from the rock’s surface...

A view of Tethys, one of Saturn's larger icy moons, taken on Nov. 16, 2016. (NASA/JPL-Caltech/Space Science Institute) NASA described Saturn’s moon Tethys as looking like a giant eyeball, but Star Wars fans may see a certain galactic superweapon known as the Death Star. Though the satellite may give Chewbacca and company flashbacks, NASA says , according to a release. An enormous crater on the moon, Odysseus, gives it its eyeball-like appearance. The void was created by a large impact,...

At a Glance Earth's magnetic poles may undergo a full reversal, according to researchers.There's no way to predict pole reversals yet, but scientists say the planet is overdue for one. The magnetic field acting as our planet’s invisible armor may be close to a reversal in which the magnetic poles trade places, scientists say. There is currently no way to predict geomagnetic reversals, but because we’re overdue for one and the Earth’s magnetic field has been decreasing, , reports the...

Saturn’s infamous rings have always made it stand out in the cosmos, but newly released images from NASA show an incredibly detailed view of the icy bands as they haven’t been seen before. NASA’s Cassini spacecraft has entered its “Ring-Grazing” orbits phase, which has allowed it to capture , according to a release from the space agency. The spacecraft came close to the rings when it arrived at Saturn, but the image quality was not as high as these new...

The Heensche Molen area of The Netherlands glows white with snow in a satellite image captured on Jan. 19, 2017. (NASA Earth Observatory) At a Glance Snowfall in the Netherlands made for odd satellite images when it appeared in one isolated spot.Researchers believe fog-induced snow is behind the peculiar precipitation. Snowfall in the Netherlands isn’t out of the norm, but recent satellite images of the country showed quite a puzzling scene. While a neighborhood in the country was dusted with...
