16-06-27 Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of structure in it. One hundred years after Einstei...

16-01-03 Researchers have found a new way to measure the pull of gravity at the surface of a star. For distant stars with planets orbiting them, this information is key in determining whether any of those planets can harbour life. The new method is described...

15-10-22 When a star comes too close to a black hole, the intense gravity of the black hole results in tidal forces that can rip the star apart. In these events, called tidal disruptions, some of the stellar debris is flung outward at high speeds, while the...

15-06-26 A new NASA computer simulation shows that dark matter particles colliding in the extreme gravity of a black hole can produce strong, potentially observable gamma-ray light. Detecting this emission would provide astronomers with a new tool for unders...
