Neutron star collisions are a "goldmine" of heavy elements, study finds

Most elements lighter than iron are forged in the cores of stars. A star's white-hot center fuels the fusion of protons, squeezing them together to build progressively heavier elements. But beyond iron, scientists have puzzled over what could give rise to gold, platinum, and the rest of the universe's heavy elements, whose formation requires more energy than a star can muster.

Last month, the Pentagon successfully tested an air-breathing hypersonic weapon capable of moving five times faster than the speed of sound.
The US Navy and Army tested hypersonic weapon component prototypes on Wednesday, the Pentagon said.
All three tests were successful, it added.

Earlier this week, Western media alleged that China had carried out a missile test in the summer involving a nuclear-capable hypersonic glide vehicle. Beijing dismissed the claims, saying its test involved reusable rocket technology. On Thursday, the Financial Times reported that the PRC had carried out not one, but two hypersonic missile tests.

Hot Jupiters - giant gas planets that race around their host stars in extremely tight orbits - have become a little bit less mysterious thanks to a new study combining theoretical modeling with observations by the Hubble Space Telescope.
While previous studies mostly focused on individual worlds classified as "hot Jupiters" due to their superficial similarity to the gas giant in our own so New far-out NASA 'travel' video: kayaking on Titan, skydiving on exoplanet

NASA knows people can't travel to exoplanets light-years away, but the space agency hopes a new, highly fictionalized video will inspire dreams of such far-off travel.
The video depicts wild, even wacky, scenes of people kayaking in deadly methane lakes on Saturn's moon Titan, skydiving on exoplanet HD 40307-g, which is 42 light-years away, and watching twin suns on Kepler-16b - 200 li Blue Origin, partners announce plans for private space station

Jeff Bezos' Blue Origin on Monday announced it wants to launch a space station that will house up to 10 people in the second half of the decade, as the race to commercialize the cosmos heats up.
"Orbital Reef," described in a press statement as a mixed-use business park in space that will support microgravity research and manufacturing, is a joint venture with commercial space company Sierra Space and has the support of Boeing and Arizona State University.
"For over sixty years, NASA and other space agencies have developed orbital space flight and space habitation, setting us up for commercial business to take off in this decade," said Blue Origin executive Brent Sherwood.
"We will expand access, lower the cost, and provide all the services and amenities needed to normalize space flight.
NASA's uncrewed Artemis moon mission set to launch in February
Monday, 25 October 2021 14:57 Write a comment
NASA's uncrewed Artemis 1 mission to the moon is on track to launch in February, the U.S. space agency said.
The Orion spacecraft was secured this week atop the powerful Space Launch System rocket at NASA's Kennedy Space Center in Florida, meaning the mission was entering its final phase of preparations.
For its flight next year, Orion will swing around the moon without astronauts on board.
It will be a critical test of the Artemis program, which aims to land astronauts on the moon by 2024 and establish a sustained human presence there by 2028, part of the U.S. government's ambitious efforts to get people to Mars in the 2030s.
Artemis has been hit by delays, and even top NASA officials have conceded that the targets will be difficult to meet.
A specific launch date for Artemis 1 will be set after "wet dress rehearsal," a test set for early next year in which the liquid propellants are filled into the massive next-generation rocket, which at 98 meters stands taller than the Statue of Liberty.
The United States remains the only country to have put humans on Earth's nearest neighbor.
