Black hole hunter launched by Nasa

Harrison, a professor at the California Institute of Technology in Pasadena, California, said it will be the “first telescope to focus high energy X-rays” and will make “images that are 10 times crisper and 100 times more sensitive than any telescope that has operated in this region of the spectrum.”

NuSTAR is more potent than its predecessors because of the way it focuses high-energy X-ray light by using nested shells of mirrors to prevent the light from reflecting off.

With 133 nested mirrors in each of two optical units, the telescope also uses state-of-the-art detectors and a long mast that connects the optical units to the detectors and allows enough distance for a sharp focus.

The 33-foot mast will launch in a folded-up position but will extend about a week after launch, bringing it to about the length of a school bus.

“It used to be thought that black holes were rare and exotic – that was just 20 years ago,” Harrison told reporters.

“Today we know that every massive galaxy, like our Milky Way, has a massive black hole at its heart.”

The new observatory aims to give a better view of the workings of a black hole, since the dust and gas that gets sucked into the gravity of a black hole becomes quite hot from speed and friction created as it circulates around the edge.

Its method of launch, from a rocket hitched to a plane, was less expensive than ground-based launches because it required less fuel to boost cargo away from the pull of Earth’s gravity, the US space agency said.

The jet took off from Kwajalein Atoll in the Marshall Islands.

The first data from the telescope is not expected for about 30 days.
