The Hubble space telescope has been circling Earth since 1990 and has spotted a few planets #and also helped determine what some extra-solar worlds are made probably of.

But Hubble's 2. 4m (7. 9ft) mirror is too small to see planets smaller than Jupiter,

which will allow it to"probe down to smaller planetary sizes than Hubble, to roughly two-to-three times larger than Earth,

#Exoplanet weather forecast calls for clouds University of Chicago rightoriginal Studyposted by Steve Koppes-Chicago on December 31 2013a team of scientists report they have characterized definitively the atmosphere of a super-Earth class

which is known as GJ1214B is classified as a super-Earth type planet because its mass is intermediate between those of Earth and Neptune.

Recent searches for planets around other stars (xoplanets have shown that super-Earths like GJ 1214b are among the most common type of planets in the Milky way galaxy.

Because no such planets exist in our solar system the physical nature of super-Earths is largely unknown.

Previous studies of GJ 1214b yielded two possible interpretations of the planet s atmosphere. Its atmosphere could consist entirely of water vapor

and first author of the new paper. his advance lays the foundation for characterizing other Earths with similar techniques.?

GJ 1214b is located just 40 light-years from Earth in the direction of the constellation Ophiuchus.

Because of its proximity to our solar system and the small size of its host star GJ 1214b is the most easily observed super-Earth.

Models of super-Earth atmospheres predict clouds could be made out of potassium chloride or zinc sulfide at the scorching temperatures of 450 degrees Fahrenheit found on GJ 1214b. ou would expect very different kinds of clouds to form than you would expect say on Earthkreidberg says.

#Earth s inner core spins faster than rest of planet University of Leeds rightoriginal Studyposted by Ben Jones-U. Leeds on September 17 2013the Earth s

Although Edmund Halley who also discovered the famous comet showed the westward-drifting motion of the Earth s geomagnetic field in 1692 it is the first time that scientists have been able to link the way the inner core spins to the behavior of the outer core.

because it is responding to the Earth s geomagnetic field. The findings published in the Proceedings of the National Academy of Sciences help scientists to interpret the dynamics of the core of the Earth the source of our planet s magnetic field.

In the last few decades seismometers measuring earthquakes travelling through the Earth s core have identified an eastwards

or superrotation of the solid inner core relative to Earth s surface. he link is explained simply in terms of equal and opposite actionsays Philip Livermore of the School of Earth

and Environment at the University of Leeds. he magnetic field pushes eastwards on the inner core causing it to spin faster than the Earth

but it also pushes in the opposite direction in the liquid outer core which creates a westward motion. he solid iron inner core is about the size of the Moon.

The fact that the Earth s internal magnetic field changes slowly over a timescale of decades means that the electromagnetic force responsible for pushing the inner and outer cores will itself change over time.

The authors used a model of the Earth s core that was run on the giant supercomputer Monte Rosa part of The swiss National Supercomputing Centre in Lugano Switzerland.

Using a new method they were able to simulate the Earth s core with an accuracy about 100 times better than other models.

#Ice may explain odd craters on Mars Brown University right Original Studyposted by Kevin Stacey-Brown on August 6 2013brown (US) More than 600 double-layer craters on Mars may have been caused by debris

These distinctive craters were documented first in data returned from the Viking missions to Mars in the 1970s

Recent discoveries by planetary geoscientists at Brown and elsewhere have shown that the climate of Mars has varied in the past says James W. Head professor of geological science at Brown University.

During these times ice from the polar caps is redistributed into the mid-latitudes of Mars as a layer about 50 meters thick in the same place that we see that the DLES have formed.

or high latitudes areas where scientists believe there may once have been glacial ice on Mars. Ultimately understanding how DLES

and other crater types are formed could lead to a better understanding of Mars past. There are over 600 DLES on the Martian surface

so reconciling how they formed with our knowledge of the climate of Mars is pretty important Weiss says.

and eventually find their way to Earth. It s also the only known Martian sample On earth that hails from a critical period, about 2 billion years ago,

when Mars is thought to have become colder and drier than it was originally. Carl Agee of the University of New mexico in Albuquerque and his colleagues report their findings from samples of the meteorite in Science online today1."

"Agee and his collaborators have thrown open the door to a whole new part of Mars, says planetary scientist Munir Humayun at Florida State university in Tallahassee,

is"the first of a new class of Martian meteorites that provides more direct clues to the surface history of Mars. Moreover,

as the fate of a long-delayed mission to bring samples of Mars back to Earth is still uncertain.

Several lines of evidence indicate that parts of Mars were warmer and wetter, and therefore a possible haven for carbon-based life, some 4 billion years ago.

That is not a surprise, given the map of hydrogen (a stand-in for water) generated by an instrument on the Mars Odyssey orbiting spacecraft and the presence of small amounts of water in younger Martian meteorites

and the presence of water in it suggests that crustal rocks on Mars interacted with surface water that was delivered by volcanic activity,
