Scientists untangle mystery about the universe's earliest galaxies

Since beginning operations last year, the James Webb Space Telescope has provided an astonishing glimpse of the early history of our universe, spotting a collection of galaxies dating to the enigmatic epoch called cosmic dawn. But the existence of what appear to be massive and mature galaxies during the universe's infancy defied expectations - too big and too soon. That left scientists scrambling for an explanation while questioning the basic tenets of cosmology, the science of the origin and development of the universe. A new study may resolve the mystery without ripping up the textbooks.

Spain's PLD Space counts down to test rocket launch from Europe

Spanish startup PLD Space will attempt a test launch of its reusable Miura-1 rocket early on Saturday, spearheading a new generation of 'microlaunchers' after an aborted attempt in June. The rocket is due to lift off on its suborbital test mission at 2 a.m Spanish time on Saturday (0000 GMT) from Huelva in southwest Spain, marking what its designers say will be Europe's first fully private rocket launch.

New tests confirm antiquity of ancient human footprints in New Mexico

Humans trod the landscape of North America thousands of years earlier than previously thought, according to new research that confirms the antiquity of fossilized footprints at White Sands National Park in New Mexico using two further dating approaches. The footprints date to about 21,000 to 23,000 years ago, based on radiocarbon and optically stimulated luminescence dating techniques, researchers said on Thursday, showing that our species Homo sapiens already had a foothold in North America during the most-inhospitable conditions of the last Ice Age.
