Earth is about to see three total solar eclipses in just under two years, with each successive path of totality moving west to east across the globe. Here's everything you need to know to plan an exquisite triple-header.
The discovery of Gravitational Waves (GWs) in 2015 confirmed a prediction made by Einstein's Theory of General Relativity and led to a revolution in astronomy. These waves are produced when massive, compact objects (such as black holes and neutron stars) merge, creating ripples in spacetime that can be detected millions of light-years away. A decade later, researchers from the University of Amsterdam (UvA) have proposed how GWs could be used to investigate an enduring cosmological mystery - the existence of Dark Matter.
