4 weeks agoThe universe's brightest supernovae are turbocharged by newborn magnetars
Superluminous supernovae are powered by newly formed magnetars—highly magnetized, rapidly spinning neutron stars that emit intense radiation, marking the first direct observation of a magnetar's birth.

1 month agomechanical clock with rotating discs can tell what time it is on other planets
Since every planet spins at a different speed, the gears are built with different ratios: Earth takes about 24 hours to spin once, Mars takes about 24.6 hours, Jupiter spins much faster, and Saturn spins fast too. Because of this, each dial shows the real day cycle of that planet, so the clock doesn't calculate time digitally.

The first time that University of Oxford astronomer Lyla Jung saw the cosmic configuration on her monitor, she almost didn't believe it was real. But it wasand Jung and her colleagues went on to identify one of the largest rotating structures ever found in space: a chain of galaxies embedded in a spinning cosmic filament 400 million light-years from Earth. The finding, published in Monthly Notices of the Royal Astronomical Society, may give astronomers new insights into galaxies' formation, evolution and diversity, Jung says.

2 months agoAstronomers Intrigued By Impossible Structure Around Dead Star
A dead star 730 light years away appears to be forming a powerful structure around itself - and despite their best efforts, astronomers aren't sure how. The cosmic corpse, designated RXJ0528+2838, is an incredibly dense stellar remnant known as a white dwarf, with a Sun-like star orbiting around it. This binary arrangement isn't uncommon throughout the universe, but what is strange is the structure surrounding the former body: a highly energetic and luminescent cloud known as a nebula,
