Em um passado distante, Vênus pode ter sido bem parecido com a Terra. De acordo com a Nasa, o planeta teve um oceano líquido e temperaturas habitáveis por até 2 bilhões de anos após sua formação, em sua história inicial. Hoje em dia, Vênus é inabitável e sua temperatura atinge 462º C na superfície. A foto é um conceito artístico.

“These results show ancient Venus may have been a very different place than it is today,” siad Michael Way, a researcher at NASA’s Goddard Institute for Space Studies (GISS) in New York. Venus today is a hellish world.

Mercury is the closest planet to our Sun, but oddly enough, not the hottest. Since Mercury has no atmosphere, more of the Sun's heat radiates away from it whereas Venus, even though it's further away from the sun, has a thick greenhouse atmosphere trapping and retaining the Sun's heat and making it hotter.

Mars

The red planet Mars, as seen by the Hubble Space Telescope. Can you imagine seeing this in our night sky? It'd be terrifying! Image via NASA.

NASA’s recently launched Solar Dynamics Observatory, or SDO, is returning early images that confirm an unprecedented new capability for scientists to better understand our sun's dynamic processes.

A full-disk multiwavelength extreme ultraviolet image of the sun taken by SDO on March False colors trace different gas temperatures. Reds are relatively cool (about Kelvin, or F); blues and greens are hotter (greater than 1 million Kelvin, or F).

The sounds of Neptune, taken by Voyager 1. Really ambient and distant.

It’s incredibly rare that you’re going to get the sun, moon, and space station all in one image.

Lakes on Mars - SETI Editorial If we take the terrestrial model for the chronology of life development, then, stratigraphy at Gale tells us that it is possible that life was already around when those lakes formed - it was on Earth.

Moscow (Voice of Russia) Jan 2013 - Scientists believe that a large crater, which has been discovered on Mars, might have been a lake several billion years ago. A space vehicle, which NASA sent to explore Mars, has discovered layers o
