Venus is the second planet from the Sun, which makes it a hell of a lot hotter than Earth.聽Besides the planets heat, Venus is an arid, rocky wasteland dominated by volcanoes and toxic sulfuric acid clouds. That cloud layer鈥攁bout 12 miles thick鈥攕hrouds the planets surface from Earth-based observers most of the time, and recently it has been in the spotlight as a possible hiding place of alien life. The recent research modeled those clouds in greater depth, and the scientists found that the clouds on the planet arent fully composed of sulfuric acid but have some amount of ammonium salt slurries mixed in. The teams study was published in the Proceedings of the National Academy of Sciences. Our model p

Our model postulates that the compound that neutralizes the acid in the clouds is ammonia, said Janusz Petkowski, an astrobiologist at MIT and a co-author of the recent study, in an email. The source of ammonia is unknown, but could be the result of biological production of ammonia in cloud droplets. As a result of the neutralizatio

The recent work builds on highly publicized research聽published last year in Nature, which claimed to detect phosphine gas in the Venusian atmosphere.

Essentially, the researchers used machine learning to collect tweets posted during the riots, then clustered them according to variables like location, time sent, and hashtags

What researchers found was that disruptive events like windows breaking, fires, and unruly groups of people were consistently tweeted out anywhere from five minutes to an hour before London police knew about them. This tweet, for example, went out at 9:54pm. London polices first record of looting on Fore Street came 45 minutes later at 10:40PM.
