The planet Venus is arguably the most mischievous planetary body in the solar system. This is because like Saturn’s largest moon, Titan, Venus is shrouded in a thick atmosphere that can’t be viewed with optical telescopes and require radar images to see the surface. Unlike Titan, whose atmosphere looks quite dull, Venus’s swirling and awe-inspiring […] The post Could Life Exist on Venus? Peptides…

Astronomers have found signs that comets may be transporting water from the cold outer regions of a young planetary system toward the warmer area where new planets can form. The discovery could help scientists understand how water reached Earth billions of years ago. Researchers at Lund University in Sweden studied a planetary system called PDS […] The post Comets May Be Carrying Water to New Pla…
