Is Mining Asteroids That Impacted The Moon Moon Easier Than Mining Asteroids Themselves?

Universe Today - Tue, 08/12/2025 - 10:40am

The resources tucked away in asteroids promise to provide the building blocks of humanity’s expansion into space. However, accessing those resources can prove tricky. There’s the engineering challenge of landing a spacecraft on one of the low-gravity targets and essentially dismantling it while still remaining attached to it. But there’s also a challenge in finding ones that make economic sense to do that to, both in terms of the amount of material they contain as well as the ease of getting to them from Earth. A much easier solution might be right under our noses, according to a new paper from Jayanth Chennamangalam and his co-authors - mine the remnants of asteroids that hit the Moon.

The Martian Landscape Reveals Climate Secrets

Universe Today - Tue, 08/12/2025 - 10:40am

Deep cracks stretching hundreds of kilometers across the Martian surface might look like simple scars from ancient impacts, but they're actually windows into a surprisingly dynamic planetary history. New images from Europe's Mars Express spacecraft reveal how these valleys, filled with slow moving rivers of ice and rock, have preserved evidence of climate swings far more extreme than anything Earth has experienced. The story written in these Martian fractures challenges our view of the red planet.

The JWST Found Evidence Of An Exo-Gas Giant Around Alpha Centauri, Our Closest Sun-Like Neighbour

Universe Today - Tue, 08/12/2025 - 10:40am

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found strong evidence of a giant planet orbiting a star in the stellar system closest to our own Sun. At just 4 light-years away from Earth, the Alpha Centauri triple star system has long been a compelling target in the search for worlds beyond our solar system.
