Astronomers find new clue that heavy stars don't go supernova
Conventional theory states that light stars like our Sun gently blow off their layers when they die, while heavy stars explode as a supernova. But for some reason, we are so far failing to find supernovae from stars heavier than eighteen solar masses. Now a team led by SRON astronomers finds a new clue that fuels this apparent mystery.

The rese What can a young star teach us about the birth of our solar system
The familiar star at the center of our solar system has had billions of years to mature and ultimately provide life-giving energy to us here on Earth. But a very long time ago, our sun was just a growing baby star. What did the sun look like when it was so young? That's long been a mystery that, if solved, could teach us about the formation of our solar system-so-named because sol is the Latin w Anchoring single atoms
There is a dictum to "never change a running system". New methods can however be far superior to older ones. While to date chemical reactions are mainly accelerated by catalytic materials that comprise several hundreds of atoms, the use of single atoms could provide a new approach for catalysis.
An international research team, led by the TU Wien, Austria, has now developed a new method for Firefly emphasizes first Alpha launch a test flight
Firefly Aerospace is ready for the first orbital launch attempt of its Alpha rocket on a flight that is as much about collecting vehicle data as it is about reaching orbit.
Timelapse of Eutelsat Quantum launch

Experience the preparation and launch of telecommunications satellite Eutelsat Quantum by watching this unique timelapse video.
Developed under an ESA Partnership Project with satellite operator Eutelsat and prime manufacturer Airbus, Eutelsat Quantum has pioneered a new generation of satellites with the European space industry.
The footage was captured at the Airbus facility in Toulouse – where the satellite was assembled and tested – and Europe’s Spaceport in French Guiana.
The world’s first fully software-defined satellite – which will be used for communication in government, mobility and data markets – was launched on board an Ariane 5 on 30 July.

The visibility and attention space missions often get work to the industry’s advantage, from helping to attract top engineering talent to top investment dollars. But it also comes with heightened scrutiny that risks tripping up young space companies rushing to the commercial market.
US grounds Virgin Galactic after space flight 'mishap'
The US Federal Aviation Administration (FAA) on Thursday said it was grounding space flights by Virgin Galactic while it investigates why the company's July 11 voyage carrying Richard Branson deviated from its planned trajectory.
The move represents a blow to the private space company as it prepares to carry paying customers following its first fully-crewed test flight.

NASA welcomed reports Thursday that Russia's space agency is committed to supporting the International Space Station as long as it operates, administrator Bill Nelson said.
"I look forward to continued cooperation with Roscosmos on the International Space Station until 2030 and into the future," Nelson said in the emailed statement.
The space station's official decommission date NASA's Mars simulation hopefuls face tough application process
NASA won't send astronauts to Mars for at least a decade, but the agency said interest is running high in applying for a year's stint in a simulated home base on the Red Planet.
The space agency's simulation is to begin in fall 2022 inside a 3D-printed habitat at Johnson Space Center in Houston. Applications are due Sept. 17.
And being chosen for this simulation seems as difficul
