Astronomers have assembled the largest-ever compilation of high-precision galaxy distances, called Cosmicflows-4. Galaxies, such as the Milky Way, are the building blocks of the universe, each comprised of up to several hundred billion stars. Galaxies beyond our immediate neighborhood are rushing away, faster if they are more distant, which is a consequence of the expansion

NASA’s DART spacecraft successfully slammed into a distant asteroid at hypersonic speed on Monday in the world’s first test of a planetary defense system, designed to prevent a potential doomsday meteorite collision with Earth. Humanity’s first attempt to alter the motion of an asteroid or any celestial body played out in a NASA webcast from

NASA’s mission to deflect asteroid is a step towards preparing the world for a potential future asteroid strike like the one which killed the dinosaurs some 66 million years ago, the chances of which are very slim in our lifetime, Indian scientists said. In a first-of-its-kind mission, the Double Asteroid Redirection Test (DART) spacecraft successfully

Ten months after launch, NASA’s asteroid-deflecting DART spacecraft neared a planned impact with its target on Monday in a test of the world’s first planetary defense system, designed to prevent a doomsday collision with Earth. The cube-shaped “impactor” vehicle, roughly the size of a vending machine with two rectangular solar arrays, was on course to

If an earthquake strikes in the not too distant future and survivors are trapped under tonnes of rubble, the first responders to locate them could be swarms of cyborg cockroaches. That’s a potential application of a recent breakthrough by Japanese researchers who demonstrated the ability to mount “backpacks” of solar cells and electronics on the

A US astronaut and two Russian cosmonauts are set to blast off to the International Space Station Wednesday on a Russian-operated flight despite soaring tensions between Moscow and Washington over Russia’s invasion of Ukraine. NASA’s Frank Rubio and Russia’s Sergey Prokopyev and Dmitry Petelin are scheduled to take off from the Russia-leased Baikonur cosmodrome in

Mars, by virtue of its tenuous atmosphere and proximity to our solar system’s asteroid belt, is far more vulnerable than Earth to being struck by space rocks – one of the many differences between the two planetary neighbours. Scientists are now gaining a fuller understanding of this Martian trait, with help from NASA’s robotic InSight
