Earth’s oxygen will be gone in 1 billion years

A billion years from now, as the sun heats up, the warmer atmosphere will break down carbon dioxide, killing off plant life, which in turn will shut off Earth’s source of oxygen. Source: https://earthsky.org/earth/earths-oxygen-gone-1-billion-years-life-extinguished…

What triggered Yellowstone’s Steamboat Geyser?

Steamboat Geyser in Yellowstone National Park began a new period of heightened activity in March 2018. It’s had more than 100 major eruptions since then. Scientists want to know why. Source: https://earthsky.org/earth/cause-recent-eruptions-yellowstone-steamboat-geyser…

Astronomers spy a nearby, blazing hot super-Earth

Most exoplanets orbiting close to their stars don’t have atmospheres. But Gliese 486b – orbiting a red dwarf star only 24 light-years away – does. It’s close enough to see well. Astronomers will be watching it! Source: https://earthsky.org/space/gliese-486b-hot-super-earth-with-atmosphere…

Super-Earth discovered: Data will characterize planetary atmosphere models

During the past 25 years astronomers have discovered a wide variety of exoplanets, made of rock, ice and gas, thanks to the construction of astronomical instruments designed specifically for planet searches. Also, using a combination of different observing techniques they have been able to determine a large number of masses, sizes, and hence densities of the planets, which helps them to…

SpaceX Launches 60 New Starlink Satellites

SpaceX has launched another batch of its Starlink satellites — the usual complement of 60 of the low Earth orbit spacecraft, which will join the more than 1,000 already making up the existing constellation. This is the fifth launch of Starlink satellites for SpaceX this year, and the 20th overall. From a report: Earlier this year, SpaceX opened up Starlink access…

Earlier spring snowmelt in Alps threatens microbes in soil

A new study suggests that spring snowmelt in the Alps is occurring earlier in the year, and the earlier warming – due to climate change – threatens vitally important microbial communities in Alpine soils. Source: https://earthsky.org/earth/alps-climate-change-driven-snowmelt-abrupt-seasonal-change…
