Leo Satellites

MANILA, Philippines – Bright satellites orbiting close to Earth are increasingly threatening astronomical research, as a new study on Amazon’s internet satellites underscores a wider problem facing scientists worldwide. Low Earth orbit (LEO) satellites are designed to sit just a few hundred kilometers above the planet to deliver faster internetContinue Reading

MANILA, Philippines — Scientists are exploring bold ways to cool a rapidly warming planet, even as new research warns that climate change is intensifying risks to water, food, and ecosystems across the globe. A series of newly published studies shows how human-driven warming is reshaping Earth’s systems — from theContinue Reading

Astronomers may have finally solved a long-standing cosmic mystery: how minerals that require extreme heat end up inside comets formed in the coldest reaches of planetary systems. New observations from NASA’s James Webb Space Telescope show that crystalline silicates—minerals forged only at very high temperatures—are created near young stars andContinue Reading
