James Webb finds signs of an Earthlike atmosphere — why this matters?

September 12, 2025 Science Buzzer 1

The James Webb Space Telescope, known as Webb, is giving scientists new ways to spot atmospheres like Earth’s on distant planets. Webb looks at faint infrared light. That light can carry the fingerprints of gases such as water vapor, carbon dioxide, oxygen, methane and ozone. These are the same gases that help make Earth habitable.

Asteroid 2024 YR₄ Could Hit the Moon in 2032 and Send Dangerous Debris Toward Earth

August 25, 2025 Science Buzzer 1

An asteroid named 2024 YR₄, about 60 meters wide (roughly the size of a tall office building), might hit the Moon on December 22, 2032. Scientists estimate there is a 4 percent chance that it could strike the lunar surface.

If that happens, the collision would release energy equal to 6.5 megatons of TNT and create a crater about one kilometer across. Events of this scale are not common. A crater that large only forms on the Moon about once every 5,000 years.
