Retired stars join the young stars' party in the sky: how evolved stars contribute to the early heating of Earth
Thursday, 27 July 2023 08:39
Researchers from the University of Sheffield and Imperial College London have spotted a 'retired' Asymptotic Giant Branch (AGB) star passing through a young star-forming region, something which was previously thought not to happen.
The researchers identified this interaction occurred in one of the places where they think stars like our Sun must form, using the Gaia satellite, a 740m euro In search of electromagnetic counterparts of gravitational waves

Alessandra Corsi knows that when you shoot for the stars, anything can happen. It's in that spirit of intellectual curiosity that Corsi, an associate professor in Texas Tech University's Department of Physics and Astronomy, will peer into some of the farthest recesses of space in search of gravitational waves.
"We are at a critical moment in this field," she said. "We had one event in 2017 Multi-levitation bioprinting of heart models for space exploration and medicine

As a bold venture at the forefront of biomedical research, the PULSE project is poised to develop paradigm-changing bioprinting technology for applications in space and on Earth. Awarded nearly 4 million euros by the European Innovation Council's Pathfinder Open, PULSE emerges from interdisciplinary scientific collaborations and, over five years, will foster technological innovations to improve Cambodia nears completion of controversial Naval Base, amid US concerns
Thursday, 27 July 2023 08:39
Work on the controversial naval base in Cambodia, suspected by the United States of being earmarked for Chinese military use, is reportedly nearing completion. The Cambodian government confirmed on Tuesday that the base is on the brink of being operational, despite persistent international concerns.

Thursday, 27 July 2023 08:39
Black holes are the most mysterious objects in the universe, with features that sound like they come straight from a sci-fi movie. Stellar-mass black holes with masses of roughly 10 suns, for example, reveal their existence by eating materials from their companion stars. And in some instances, supermassive black holes accumulate at the center of some galaxies to form bright compact regions known Mawrth Vallis region - the deepest clay deposits on Mars

New images, created using data acquired by the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show part of the dried-up Mawrth Vallis river valley. This is one of the largest and oldest valleys on Mars, where light-coloured clay deposits up to 200 metres deep can be found in numerous places. Cl Aeolus reentry - LIVE

NASA's Juno is getting ever closer to Jupiter's moon Io
Wednesday, 26 July 2023 19:42
The spinning, solar-powered spacecraft will take another look of the fiery Jovian moon on July 30.
When NASA's Juno mission flies by Jupiter's fiery moon Io on Sunday, July 30, the spacecraft will be making its closest approach yet, coming within 13,700 miles (22,000 kilometers) of it.
NASA picks Lockheed Martin to develop nuclear rocket
Wednesday, 26 July 2023 19:04
NASA and the US military said Wednesday they had selected defense contractor Lockheed Martin to develop a nuclear powered rocket, with a view to using the technology for missions to Mars.
The Demonstration Rocket for Agile Cislunar Operations (DRACO) program may launch as soon as 2027, officials said on a call.
Nuclear thermal propulsion (NTP) systems could cut journey times, increase fuel efficiency, and require less propellant, meaning future spacecraft could carry larger payloads than today's best chemical rockets.
NTP works by pumping a liquid propellant, in DRACO's case cryogenic hydrogen, through a reactor core, where uranium atoms split apart through fission.
Engineers test printed electronics in space
Wednesday, 26 July 2023 17:23
Today's small spacecraft pack sensors, guidance and control, and operating electronics into every available space. Printing electronic circuits on the walls and structures of spacecraft could help future missions do more in smaller packages.
Engineers successfully tested hybrid printed circuits at the edge of space in an April 25 sounding rocket flight from NASA's Wallops Flight Facility near Chincoteague, Virginia. Electronic temperature and humidity sensors printed onto the payload bay door and onto two attached panels monitored the entire SubTEC-9 sounding rocket mission, recording data that was beamed to the ground.
