The surface of Venus is dry and hot—475 °C (900 °F) day and night throughout the year— and the atmospheric pressure is 90 times that of Earth’s. Few probes have entered this harsh environment, and none has survived long. Only four, all Soviet Venera space.
A new rocky planet, GJ 667Cc, orbits it’s star every 28.15 days - meaning its year equals about one Earth month - and has a mass at least 4.5 times that of Earth.
This planet is the new best candidate to support liquid water and, perhaps, life as we know it…
Astronomers from the University of Washington and Harvard University recently discovered an Earth-like planet caught in a cosmic struggle with a much larger planet — both of which orbit a star about 1,200 light years away in the Cygnus constellation.
These planets orbit extremely close to each other in cosmic terms — within 1.2 million miles at their closest points. And that fact led some folks at the UW to wonder what that must look like.
Astronomers using infrared data from the Subaru Telescope in Hawaii have discovered a “super-Jupiter” around the bright star Kappa Andromedae, which now holds the record for the most massive star known to host a directly imaged planet or lightweight brown dwarf companion.
Is that Earth? No, that’s mars…
Well, it might’ve been Mars a couple of billion years ago when it had a thick atmosphere and oceans. Kevin Gill used real elevation data from NASA’s Mars Reconnaissance Obiter (MRO) to render the planet and then added water and an atmosphere.
