Watch: NASA tests defense technology by colliding with an asteroid

NASA has successfully crashed a spacecraft into a small asteroid as part of a planetary protection test mission. While this asteroid – called Demorphos – posed no threat to Earth, the goal of the mission was to demonstrate that incoming dangerous rocks could be deflected by deliberately colliding with them. “Impact success!” NASA posted a … Read more

NASA spacecraft hits an asteroid

A NASA spacecraft struck an asteroid seven million miles away in order to divert its course, succeeding in a historic test of humanity’s ability to prevent a celestial body from destroying life on Earth. The Double Asteroid Redirection Test (DART) hit its target, the space rock Demorphos, at 7.14 p.m. ET (11.14 p.m. GMT), ten … Read more

Research shows that some trees warm up in warmer rainforests

Maria Whitman conducts field studies in Rwanda with colleagues from the University of Rwanda. Credit: Myriam Mugwamreya The capacity of rainforests to store carbon could decrease in parallel with climate change. This is due to the rates of photosynthesis in the leaves of rainforest species falling at higher temperatures and the failure of the trees’ … Read more

‘There is a serious error’: Room-temperature superconductivity study regressed | Sciences

In 2020, Ranga Dias, a physicist at the University of Rochester, and colleagues published an exciting finding in temper nature, featured on its cover. They claimed to have discovered a superconductor at room temperature: a material in which electric current flows without friction without the need for special cooling systems. Although it was just an … Read more

New findings find that the asteroid Ryugu was once part of a much larger body

Zoom / First spotted in May 1999, Ryugu is a large group of loose rubble. JAXA Japanese spacecraft Hayabusa2 He returned to Earth in December 2020 carrying soil samples collected from a nearby asteroid, 162173 Ryugu. These samples were divided among six scientific teams around the world for a sophisticated analysis to determine their composition … Read more

NASA will deliberately collide with a spacecraft in an asteroid tonight

NASA is set to deliberately crash into an asteroid spacecraft overnight to test whether technology can prevent future asteroids from colliding with Earth. Ban last minute cancellation, NASA Double Asteroid Redirect Test The DART mission is set to smash into the asteroid Demorphos at more than six kilometers per second with the aim of changing … Read more

Diamonds from 660 kilometers below the Earth’s surface reveal a water-rich environment: ScienceAlert

Deep below the surface of our world, beyond our feeble reach, mysterious processes grind and sway. Every now and then, Earth unleashes clues to its nature: tiny chthonic diamonds encasing a skate of rare minerals. From these little bits we can extract tidbits of information about our planet’s interior. A diamond recently discovered in a … Read more

Hurricane Ian relaunches NASA’s Artemis

Leading a NASA team The Artemis program for lunar expeditions He really wants to follow up on the inaugural space flight – which was scheduled for tomorrow morning. But with powerful Hurricane Ian approaching the launch pad in Florida, it’s time to move the massive Space Launch System rocket to safety. The space agency will … Read more

The asteroid that formed Vredefort crater was larger than previously thought

One of the collisions – most likely an asteroid – blasted towards Earth about two billion years ago, and collided with the planet near Johannesburg, in present-day South Africa. The impactor formed the Fredvoort crater, which today is the largest crater on our planet. Using updated simulation data, University of Rochester researchers have discovered that … Read more
