SpaceX’s Crew Dragon capsule experienced an “anomaly” during a rocket test on Saturday that sent smoke drifting high over its launchpad at the Kennedy Space Center in Florida. Elon Musk and SpaceX have been short on details so far, but unconfirmed video footage shows the spacecraft being destroyed. The same Crew Dragon capsule completed a flawless flight to the Internat...

Mercury has a heart of iron; literally

Using sophisticated software to precisely analyse how Mercury’s gravity affected the trajectory of NASA’s MESSENGER spacecraft during multiple low-altitude orbits, researchers have been able to show the small planet must have a large, solid-iron inner core measuring some 2,000 kilometres (1,260 miles) across, almost as large as Earth’s. Including its molten metal outer layer, Me...

Astronomers Find Stars Streaming from Our Galaxy’s Biggest Cluster

Most such clusters can be found out in the galaxy’s nearly empty halo; it’s likely they formed before our galaxy did. But one of these is not like the others. A view of the iconic Omega Centauri globular cluster.ESO / INAF-VST / OmegaCAM; Acknowle...

Astronomers Find Second Galaxy with No Dark Matter

“Discovering a second galaxy with very little to no dark matter is just as exciting as the initial discovery of DF2,” Yale University’s Professor Pieter van Dokkum. “This means the chances of finding more of these galaxies are now higher than we previously thought. Since we have no good ideas for how these galaxies were formed, I hope these discoveries will encourage more...

A new neutron star merger is caught on X-ray camera

In October 2017, astronomers announced the first detection of gravitational waves from the merger of two neutron stars earlier that year. The event also rung in the era of multi-messenger astronomy, as more than 70 telescopes observed the event’s afterglow in optical light, X-rays, gamma rays, and more. Now, an X-ray signal dubbed XT2 from a galaxy 6.6 billion light-years away has revealed...
