It is also an essential part of the cycle that brings material from ...

Credit: RenderArea During the past 25 years astronomers have discovered a wide variety of exoplanets, made of rock, ice and gas, thanks to the construction of astronomical instruments designed specifically for planet searches. Also, using a combination of different observing techniques they have been able to determine a large numher of masses, sizes, and hence densities of the planets, which helps them to estimate their internal composition and raising the number of planets which have been disc...

 E-Mail The planet Mars has no global magnetic field, although scientists believe it did have one at some point in the past. Previous studies suggest that when Mars global magnetic field was present, it was approximately the same strength as Earths current field. Surprisingly, instruments from past Mars missions, both orbiters and landers, have spotted patches on the planets surface that are strongly magnetized--a property that could not have been produced by a magnetic field similar to Earths...

Hurricanes are known to occur in the lower atmosphere of Earth and even other planets, but had never before been detected in the upper atmosphere. An international team of scientists made the unprecedented discovery during retrospective analysis of satellite observations. The hurricane occurred during surprisingly low geomagnetic activity, and suggests they could occur in the upper atmosphere of other planets too.

The team discovered that the creation of these chemicals is amplified significantly by minerals in marine sediment...

 E-Mail PROVIDENCE, R.I. [Brown University] -- Volcanic rock samples collected during NASAs Apollo missions bear the isotopic signature of key events in the early evolution of the Moon, a new analysis found. Those events include the formation of the Moons iron core, as well as the crystallization of the lunar magma ocean -- the sea of molten rock thought to have covered the Moon for around 100 million years after it formed. The analysis, published in the journal Science Advances, used a tech...
