Space Dust Reveals Arctic Ice Conditions Before Satellite Imaging

Arctic sea ice has declined by more than 42% since 1979, when regular satellite monitoring began. As the ice grows thinner and recedes, more water is exposed to sunlight.

Rocky Planets Orbiting Small Stars Could Have Stable Atmospheres Needed To Support Life

Since its launch in late 2021, NASA’s James Webb Space Telescope has raised the possibility that we could detect signs of life on exoplanets, or planets outside our solar system.
