Enormous rings may have graced many of the planets in the early solar system, giving rise to the moons that circle them today, scientists say.
A new computer model suggests that the natural satellites of planets in our solar system may have formed from rings of matter, rather than from the clouds of gas currently thought to have created them.
Scientists may now understand why some parts of the planet's crust have much higher concentrations of gold than others do.
Gold, as well as other rare metals, can be brought to the surface by plumes of molten rock from deep within the mantle, the layer underneath Earth's crust, producing background levels of gold up to 13 times higher than elsewhere, according to research published Oct. 19 in the journal Geology.
Amazing new photos from NASA's Cassini probe orbiting Saturn reveal a dizzying glimpse into a monster storm raging on the ringed planet's north pole. …Read More »
Cassini took the spectacular Saturn storm photos yesterday (Nov. 27) and relayed it back to Earth the same day, mission scientists said in a statement. The pictures reveal a swirling storm reminiscent of the recent Hurricane Sandy that recently plagued our own planet.
Astronomers have seen a distant galaxy that blasts away material with two trillion times the energy the sun emits — the biggest such eruption ever seen.…Read More »
That ejection of matter could answer an important question about the universe: why are the black holes in the centers of galaxies so light?
Computer models of the early universe usually produce a virtual cosmos that looks like ours except for one thing. The ratio of the mass of black holes in galaxy centers to the rest of the matter in galaxies is larger in the simulations than in the real universe.
Lava overtopped a seaside cliff in Hawaii this weekend, sending up spectacular steam plumes caught on video and in pictures by a camera crew aboard a helicopter.

The slow-moving stream of molten rock, a sticky form of lava called "pahoehoe," crested the edge around 1 p.m. Hawaiian time on Saturday (Nov. 24), said Ken Hon, a geology professor at the University of Hawaii in Hilo. Hon and his students were accompanying a documentary crew at the site and saw the lava pour over the cliff.
