Poll results contradict concerns that the pause added to hesitancy.

What if Starship Didn’t Do a Landing Burn at All?

Another 3D graphic artist has a proposal for Musk: to "catch" the Starship using a special launch tower, kind of like they want to do with the Super Heavy. The post What if Starship Didn’t Do a Landing Burn at All? appeared first on Universe Today.

Hungry, Hungry Microbes in Tree Bark Gobble Up Methane

Bad news: Trees emit methane, a greenhouse gas. Good news: Some are home to bacteria that can't get enough of it.

Missing Arctic Ice Fueled the 'Beast of the East' Winter Storm

An anonymous reader quotes a report from Ars Technica: Extreme weather has become the new normal -- whether it's precipitation, drought, wind, heat, or cold. The question of how the ever-shrinking layer of Arctic sea ice has contributed to any of these changes has prompted some lively discussion over the past few years. Researchers have proposed that a weakened jet stream driven by vanishing Arctic sea ice might play a large role in extreme winter events like the descending polar vortex that struck North America earlier this year. But the idea hasn't held up well in light of more recent evidence. But now, researchers have identified a direct link between extreme winter weather and sea ice loss. The 2018 "Beast of the East" winter storm hit Europe with record-breaking snowfall and low temperatures. And potentially as much as 88 percent of that snowfall originated from increased evaporation of the Barents Sea. The working hypothesis is that Arctic sea ice acts as a cap for Arctic waters, limiting evaporation. Less sea ice and warmer Arctic temperatures mean more evaporation, potentially explaining the increased severity of winter storms like the Beast of the East. Until now, it's been tough to measure direct evidence linking sea ice loss to extreme European winters, but recent advances in technology are making this a little less challenging.

Meteorites Hold Early Atmospheres From Across the Solar System

Since they were formed in the early solar system, many meteorites offer an unadulterated view into what that solar system was made out of, or what happened to it as we reported before.  Recently a team of researchers led by Maggie Thompson at University of California Santa Cruz (UCSC) took a look at the chemical … Continue reading "Meteorites Hold Early Atmospheres From Across the Solar System" The post Meteorites Hold Early Atmospheres From Across the Solar System appeared first on Universe Today.
