KILLER asteroids capable of wiping out entire cities may soon be harder to spot due to a horde of satellites that Elon Musk is hurling into space. The South African billionaire’s Starlink project aims to set up a mega-constellation of internet-beaming spacecraft that astronomers fear...

Alien civilizations with technology on a par with humanity’s could be detectable using today’s instruments. A new study suggests that if geostationary satellites are thick enough around an alien world, they could be spotted with telescopes already hunting for undiscovered planets. Both governments and private...

Satellites are, to some degree, “mysterious” objects. They travel in space, which feels like an exotic place because most of us have never been there. They are so far away that we cannot see them. They usually cost millions or billions of dollars, which means...

Already boasting scores of satellite launches, a handful of crewed orbital missions and two lunar probes, Red China now stands poised to assume a leading role in the Big Black. Since kicking off in 1992, China’s space program has chalked up modest but steady progress,...

Scientists are offering social media users the chance to name 5 of Jupiter’s most recently discovered moons. Last summer a team lead by Scott Sheppard from the Carnegie Institution for Science discovered a total of 12 new moons around the gas giant, bringing Jupiter’s total...

Three NASA satellites helped researchers to produce new models to see how shocks associated with coronal mass ejections, or CMEs, propagate from the Sun. Much the way ships form bow waves as they move through water, CMEs set off interplanetary shocks when they erupt from...

Two satellites will track the continuous movement of water and other changes in Earth’s mass on and beneath the planet’s surface . A joint U.S./German space mission – the twin spacecraft of the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) – successfully launched at 12:47...
