That was a surprise—and a possible indication that something crucial was missing in those models: magnetism. Stellar Symmetry Last year, Gang Li, an asteroseismologist now at KU Leuven, went digging through Kepler’s giants. He was searching for a mixed-mode signal that recorded the magnetic field in the core of a red giant. “Astonishingly, I actually found … Read more
Like any object, black holes take time to grow and form. And like a 6-foot-tall toddler, Fan’s supersize black holes were too big for their age—the universe wasn’t old enough for them to have accrued billions of suns of heft. To explain those overgrown toddlers, physicists were forced to consider two distasteful options. Decades ago, … Read more
After Euclid blasts off, it would journey to a spot known as Lagrange level 2, about 1.5 million kilometers from Earth, the place the telescope could have a transparent view of deep house whereas with the ability to talk with astronomers and revel in steady daylight on its photo voltaic panels. The telescope is supplied … Read more
The NANOGrav group was basically in a position to flip the Milky Manner into a large gravitational wave detector by measuring the indicators from these pulsars to find out when a wave nudged them. The collision of monumental black holes—or another extraordinarily energetic course of—generates gravitational waves that ever-so-slightly squeeze and stretch space-time, tweaking the … Read more
