A better understanding of how cirrus clouds form

New research by a team led by scientists from Purdue University has shown that trees and plants play an important role in the formation of cirrus clouds. This finding has implications for agriculture, urban development and the modeling of climate change. Photo credit: J.

Did Pioneer see phosphine in the clouds of Venus decades ago?

The discovery of phosphine in the atmosphere of Venus has aroused great interest. It has the potential to be a biosignature, though some researchers have thrown cold water on the idea since it was discovered. But at least it looks like the discovery is real, and that one of NASA’s pioneering spacecraft discovered the elusive gas back in 1978. And …

Life on Venus? Astronomers see the phosphine signal in its clouds

On such worlds, “as far as we can tell, only life can produce phosphine,” said Dr. Sousa-Silva. She has long studied the gas, with the theory that finding that it is being emitted by rocky planets orbiting distant stars could be evidence that life exists elsewhere in the Milky Way. Here on earth, phosphine is found in our intestines, in …

Scientists have just found a way for machines to see through clouds and fog

Whether it’s robots working in a disaster area, autonomous cars moving around the city, or satellites looking through space – machines that can see through clouds, haze, and fog are incredibly useful – and scientists may have just developed the best system. The newly developed system works with an algorithm that measures the movement of individual light particles or photons …

Creek Fire in California creates clouds of smoke up to 50,000 feet, campers saved

An explosive wildfire in California that saw dozens rescued from a campground by a military helicopter has created massive clouds of smoke that stretch into the sky. The Creek Fire exploded near Shaver Lake on Saturday and scorched about 36,000 acres when it jumped a river near the lake, endangering the only road into Mammoth Pool Campground. The rapidly spreading …

Clouds of star-forming gas are shot through the galaxy “like spheres”

A torrent of searing atomic wind is pouring from the center of our galaxy, and astronomers have discovered two tiny islands of unborn baby stars trapped in the tide. These two pieces of cosmic driftwood are actually freezing clouds of hydrogen Gas, each as cold as Pluto (approximately minus 400 degrees Fahrenheit or minus 240 degrees Celsius) and carry the …

Microbes in the clouds of Venus | Daily planets

In an article just published in the magazine AstrobiologySara Seager from MIT and colleagues suggest how microbial life could live permanently in the lower atmosphere of Venus. The idea that microbes could exist in the Venusian clouds at an altitude of 50 to 65 kilometers above the ground was proposed by the late Carl Sagan more than 50 years ago …
