Abandoned SpaceX Rocket Will Crash Into The Moon Within Weeks, Scientists Say

A chunk of a SpaceX rocket that blasted off seven years ago and was abandoned in space after completing its mission will crash into the Moon in March, experts say. The rocket was deployed in 2015 to put into orbit a NASA satellite called the Deep Space Climate Observatory (DSCOVR).   Since then, the second … Read more

Wild New Paper Suggests Earth’s Tectonic Activity Has an Unseen Source

Earth is far from a solid mass of rock. The outer layer of our planet – known as the lithosphere – is made up of more than 20 tectonic plates; as these gargantuan slates glide about the face of the planet, we get the movement of continents, and interaction at the boundaries, not least of which is … Read more

Webb Telescope Reaches Its Final Destination Far from Earth

NASA’s James Webb Space Telescope has just reached its final destination—around a gravitationally special spot in space known as the second Lagrange point, or L2. The US$10-billion observatory could spend 20 or more years there, gathering unprecedented insights about the Universe as it stares into deep space. Webb, which is the most complex telescope ever … Read more
