Apart from black holes, magnetars may be the most extreme stars in the universe. With a diameter less than the length of Manhattan, they pack more mass than that of our sun, wield the largest magnetic field of any known object — more than 10 trillion times stronger than a refrigerator magnet — and spin …

This year, we joined Ars Electronica In Kepler’s garden online program, a collective effort to reconnect. We hosted three interactive workshops, spanning a diverse range of SEI’s current research thrusts: Wellbeing in Extreme Environments, led by Maggie Coblentz; Interplanetary Time, Communication and Longevity, led by Che-wei Wang and Sands Fish; and A New Moon Landing, …

Methods from scientific machine learning could address the challenges of testing the stability of rocket engines, researchers report. Time, cost, and safety prohibit testing the stability of a test rocket using a physical build “trial and error” approach. But even computational simulations are extremely time consuming. A single analysis of an entire SpaceX Merlin rocket …

In the middle of the night, invisible to anyone but special telescopes in two Chinese observatories, satellite Micius sends particles of light to Earth to establish the world’s most secure communication link. Named after the ancient Chinese philosopher also known as Mozi, Micius is the world’s first quantum communications satellite and has, for several years, …

“It’s not rocket science” may be a tired cliché, but that doesn’t mean designing rockets is any less complicated. Time, cost and safety prohibit testing the stability of a test rocket using a physical build “trial and error” approach. But even computational simulations are extremely time consuming. A single analysis of an entire SpaceX Merlin …

Understanding how our universe came to be what it is today and what its final destiny will be is one of the biggest challenges in science. The awe-inspiring display of countless stars on a clear night gives us some idea of the magnitude of the problem, and yet that is only part of the story. …
