Diverse Minerals in Martian Rocks

Examining initial samples of rocks collected by NASA's Mars Curiosity rover, scientists have found a wide diversity of minerals in the lower-most layers of Mount Sharp Mountain.
The minerals found in the four samples drilled near the base of Mount Sharp suggest several different environments were present in ancient Gale Crater.
At the base are minerals from a primitive magma source; they are rich in iron and magnesium.
Moving higher in the section, scientists saw more silica-rich minerals.

Two Massive Planets Discovered

Astronomers have discovered two new gas giant planets, orbiting a star located about 138 light years away from the Earth.
One of the two worlds is a Saturn-mass planet, while the other one is a cold exoplanet several times more massive than Jupiter.
The two planets orbit a star HD 27894, which was first detected in 2005 and is about 20 per cent less massive than the sun.
The two gas giant exoplanets have received designations HD 27894 c and HD 27894 d.
