Did gravitational wave detector find dark matter?

A matter of scientific speculation since the 1930s, dark matter itself cannot yet be detected, but its gravitational effects can be. Now, eight scientists from Johns Hopkins University consider the possibility that the first black hole binary detected by LIGO could be part of this mysterious substance known to make up about 85 percent of the mass of the universe.

Gluttonous young star may hold clues to planet formation

In 1936, infant star FU Orionis began gobbling material from its surrounding disc of gas and dust with a sudden voraciousness, eating the equivalent of 18 Jupiters in the last 80 years. During a three-month binge, as matter turned into energy, the star became 100 times brighter, heating the disc around it to temperatures of up to 6,650 °C.

Extreme trans-Neptunian objects lead the way to Planet Nine

In the race towards the discovery of Planet Nine, scientists from around the world strive to calculate its orbit using the tracks left by the small bodies that move well beyond Neptune. Now, astronomers from Spain and Cambridge University have confirmed that the orbits of the six extreme trans-Neptunian objects that served as a reference to announce the existence of Planet Nine are not as stable as originally thought.

Scientists to provide update on the search for gravitational waves

This year marks the 100th anniversary of the first publication of Albert Einstein’s prediction of the existence of gravitational waves. With interest in this topic piqued by the centennial, researchers from UK universities in Glasgow, Birmingham, and Cardiff will discuss their ongoing efforts to observe and measure cosmic gravitational waves for scientific research in London on Thursday, 11 February.
