Closest Habitable Planet Found

Astronomers have discovered the closest potentially habitable planet found outside our solar system, orbiting a star just 14 light years away.
The planet, more than four times the mass of Earth, is one of three that the team detected around a red dwarf star called Wolf 1061.
It is exciting find because all three planets are of low enough mass to be potentially rocky and have a solid surface, and the middle planet, Wolf 1061c, sits within the 'Goldilocks' zone where it might be possible for liquid water - and maybe even life - to exist.
Their masses are at least 1.4, 4.3 and 5.2 times that of Earth, respectively.

PSLV-C29 Rocket Successfully Launches Six Satellites

ISRO's Polar Satellite Launch Vehicle blasted off from the first launch pad at Sriharikota, with six Singaporean satellites.
All the satellites have been successfully put into orbit at an altitude of 550 km.
The PSLV rocket is a four stage/engine rocket powered by solid and liquid fuel alternatively.
Out of the six satellites, the TeLEOS-1 is the main passenger for the PSLV rocket and hence, the mission is called TeLEOS mission by ISRO.

Japanese Space Probe Goes Into Orbit around Venus

Japan's "Akatsuki" probe had successfully entered into orbit around Venus after an initial attempt at reaching the second planet from the sun failed five years ago.
This is the first time that a Japanese space probe has entered into the orbit of another planet.
Akatsuki, meaning dawn, blasted off in 2010 in a mission to observe the toxic atmosphere and super-hot volcanic surface of Venus.
