NASA’s Moon-bound mega-rocket finally leaves the launchpad.
Researchers solved the “hundred-year-old riddle” of how plant vascular systems become increasingly complex in larger plants. Their research shows these complex arrangements help prevent embolisms — air pockets that form during droughts and block vascular conduits.
Researchers found the earliest evidence of prehistoric humans using fire to cook from 780,000 years ago — 600,000 years earlier than the next-earliest example. The finding came from analysis of the teeth of a carp-like fish, which show signs of exposure to heat suitable for cooking.
JWST captured a stunning image of a protostar in the Taurus star-forming region. The telescope’s infrared camera allows it to see dust gathering around the forming star and gas ejected in its formation. The star itself is hidden in the center of the hourglass shape.
NASA successfully launched its Artemis I mission, which will collect data and test components for future crewed flights to the Moon. Plagued by coolant leaks and poor weather, the historic launch was delayed for months before the SLS finally took flight just before 2 a.m. Eastern Wednesday.
