In the last few decades, our space program has made many discoveries in astronomy that may be considered important for the existence of life on other planets and moons in our solar system and in systems beyond ours.  Some of the more recent discoveries are listed below. 

 

*   Water Vapor Found on Neptune-size Alien Planet  - a Neptune-size planet known as HAT-P-11b has been found to have telltale traces of water vapor in its atmosphere according to scientists.  Space.com - September 24, 2014.

 

*   Three Nearly Earth-size Planets Found Orbiting Nearby Star: One is 'Goldilocks' Zone - a team of researchers led by University of Arizona scientist Ian Crossfield have discovered a red dwarf star located 150 light years from Earth with three planets only slightly larger than Earth, one of which orbits the so-called 'Goldilocks' zone where tempratures are mild enough for liquid water and perhaps life to exist.  Science Daily.com - January 16, 2015

 

*   Large Methane Storms Discovered on Uranus - astronomers using the Keck telescope and the Hubble Space telescope have found large methane storms on Uranus, the seventh planet from the sun.  Astronomers are now trying to find out exactly what is driving these storms.  The Science Times - March 11, 2015

 

Curiosity Rover Finds Biologically Useful Nitrogen on Mars - an instrument onboard the Mars Curiosity Rover has made the first detection of nitrogen during a heating of Martian sediments session.  This adds to the evidence that ancient Mars may have been habitable for life.  NASA/JPL News - March 24, 2015

 

*   Mercury, First Planet From the Sun: Latest Discoveries - the Mercury MESSENGER spacecraft which went into orbit around Mercury in March, 2011 has ended its mission by crashing into the planet on April 30, 2015.  The mission made several discoveries during its time in orbit.   Space.com - May 2015
