- We’ve found a rocky, temperate planet’s atmosphere for the first time
Astronomers have discovered an atmosphere around a rocky, temperate exoplanet for the first time. Previously, atmospheres were only detected on very large or extremely hot exoplanets, but this discovery involves a planet potentially suitable for life.
- Will We Ever Find Alien Civilizations?
The article explores the ongoing search for intelligent life beyond Earth, noting that despite decades of effort, no conclusive evidence has been found. Occasional intriguing signals, such as fossilized structures in meteorites or unusual gases in exoplanet atmospheres, spark brief hope but ultimately remain unconfirmed.
- This planet survived the death of its star—and kept its atmosphere
Astronomers observed an atmosphere around a giant planet orbiting a white dwarf, marking the first time such a phenomenon has been documented. The planet survived its star's death and retained its atmosphere.
- Earth’s permafrost could soon release hidden ‘deep carbon,’ supercharging warming
Melting permafrost is releasing carbon into the atmosphere, and a new analysis suggests scientists may have underestimated the severity of the situation.
- Bluesky is getting ‘communities’
Bluesky is introducing 'communities' as smaller, interest-based spaces for users to engage more deeply. The feature will be built on the decentralized AT Protocol and is part of the 'Atmosphere' ecosystem. Users will be able to create, join, post in, and receive updates from these communities.
- Astronomers finally solve Saturn’s decades-long spin mystery
Astronomers used the James Webb Space Telescope to solve a decades-old mystery about Saturn's changing rotation rate. The variation was caused by powerful atmospheric winds, not changes in the planet's speed, with Saturn's northern lights heating the atmosphere to create a self-sustaining cycle of winds, electrical currents, and auroras.
- Scientists just found where airborne microplastics really come from
New research reveals that land sources emit over 20 times more airborne microplastics than the ocean, challenging prior assumptions. Scientists also found previous models overestimated atmospheric plastic levels.
