Leo Satellites

MANILA, Philippines โ€“ Bright satellites orbiting close to Earth are increasingly threatening astronomical research, as a new study on Amazonโ€™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

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 NASAโ€™s James Webb Space Telescope show that crystalline silicatesโ€”minerals forged only at very high temperaturesโ€”are created near young stars andContinue Reading

Claims that Earthโ€™s days will soon last 25 hours are going viral. Science says Earthโ€™s rotation is slowingโ€”but not anytime soon enough to affect human life.

Scientists for decades have wondered: Could Earthโ€™s immense rotational energy be harnessed to generate electricity? The idea seemed promisingโ€”our planet spins through its own magnetic field, which, in theory, should induce an electric charge. But past attempts to capture this energy failed, dismissed by conventional physics as an impossible dream.Continue Reading

Back in 2001, British electrical engineer Roger Shawyer introduced something that made physicists do a double takeโ€”the EmDrive, a so-called โ€œimpossible drive.โ€ Why impossible? Because it claimed to work without any propellant, seemingly flipping Newton and Einstein by defying the conservation of momentum. Unsurprisingly, scientists werenโ€™t buying it. For twoContinue Reading
