When Hubble swings from one galaxy to another, engineers fire no thrusters—Hubble has none. They change the speeds of four internal reaction wheels, making the observatory rotate the opposite way, while magnetic bars push against Earth’s field to bleed off excess momentum: a propellant-free steering system used since 1990.
When the Hubble Space Telescope finishes observing one galaxy and turns toward another, nothing fires into space. There…

Earth’s centre of mass wanders several millimetres relative to the solid planet over the course of each year, as monsoon rains, snowpack, ocean water and shifting air masses redistribute weight around the globe.
Earth has a centre of mass, but it is not a point permanently fixed inside the rock. Water,…

Twenty-two years of X-ray timing suggest the disk around pulsar 4U 1626−67 may have flipped from rotating backward to forward in 2008, turning years of spin-down into spin-up — though the evidence remains indirect.
For decades, the ultracompact X-ray binary 4U 1626−67 has behaved like a machine that periodically changes gear. Its…
