Today, June 29, a robotic SpaceX Dragon cargo capsule began its return to Earth from the International Space Station (ISS). Today, at 12:30 p.m. EDT (16:30 GMT), the Dragon detached from the ISS while the two spacecraft were hovering over the northeastern Indian Ocean, west of Indonesia. Now, the SpaceX capsule is on its way…
Following 15 years of data collection in a galaxy-sized experiment, scientists have “heard” the perpetual chorus of gravitational waves rippling through our universe for the first time—and it’s louder than expected. The groundbreaking discovery was made by scientists with the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) who closely observed stars called pulsars that…
Since carbon compounds are the building blocks of all known life, researchers attempting to comprehend how life evolved on Earth and elsewhere in our universe are particularly interested in them. As a result, many astronomers are very interested in the study of organic (carbon-containing) chemistry in interstellar space. Using NASA’s James Webb Space Telescope, an…
One day, human organ transplants could be made easier thanks to the success of freezing and thawing kidneys transplanted from rats. The achievement of transplanting rat kidneys that had been frozen for up to one hundred days in ultracold storage by researchers at the University of Minnesota is a significant milestone that has the potential…
Excitons, or particle pairs made of an electron bound to an electron hole, can form when some semiconductors absorb light. Exciton states unique to tungsten disulfide (WS2) crystals in two dimensions cannot be found in other materials. However, these states last only a short time and can change very quickly. A novel method for creating…
A replay of our live coverage of the countdown and launch of a SpaceX Falcon 9 rocket carrying PSN’s SATRIA communications satellite from Space Launch Complex 40 at Cape Canaveral Space Force Station, Florida, can be found below. We are on Twitter. A European-built communications satellite was the centerpiece of a nearly $550 million project…
