After successfully coming out of solar conjunction late last month, the Curiosity rover has resumed its science activities, beginning with the second drilling into bedrock, it was reported yesterday. This location, a piece of bedrock called “Cumberland,” is only about 2.75 metres (9 feet) west of the first drill site, called “John Klein.”

Could life exist in Venus’ atmosphere?

Venus has a reputation for being one of the most inhospitable places in the solar system, and deservedly so. Its thick carbon dioxide (and acidic) atmosphere has a crushing pressure similar to that in the deepest oceans on Earth and the scorching temperature on the surface is hot enough to melt lead. It’s like that everywhere on the planet, all the time. It has therefore been considered an extremely unlikely environment to support any kind of life. Even the toughest microbes here would find survival next to impossible. There is however a possibility, even if remote, that the upper atmosphere of this hellish world could be habitable, according to some scientists.

Hurricanes are an incredible force of nature, and these huge rotating vortexes of wind are an amazing sight when viewed from space. But Earth is not the only planet that has hurricanes, and there is one on Saturn that dwarfs any on our own planet. Now, the Cassini spacecraft has taken more breath-taking colour images of this colossal wind storm.
