Space telescopes uncover supermassive black hole winds

By - February 21, 2015 3 Pictures
Supermassive black holes are titanic oddities. Usually sited at the core of galaxies and various high-energy phenomena such as quasars, their mass can be anywhere from that of a hundred thousand to billions of suns. Now observations from NASA and ESA space telescopes are shedding light on the incredibly powerful cosmic winds they produce, which can have more energy than an entire galaxy. Read More

Supermassive black hole found to rotate near speed of light

By - March 6, 2013 6 Pictures
The rotation of a supermassive black hole (SBH) has been definitively measured for the first time by combining x-ray data obtained by the x-ray space telescopes XMM-Newton (soft x-rays) and NuSTAR (hard x-rays). The SBH at the center of a galaxy called NGC 1365 was found to be spinning at 84 percent of the maximum speed allowed by general relativity – or roughly speaking, the edge of the black hole is rotating at 84 percent of the speed of light.

Blazing black holes: NuSTAR provides a fresh view of the Universe

By - January 14, 2013 11 Pictures
Black holes, which abound in the Universe, convert matter into geometry – the larger the amount of matter that disappears through the event horizon, the larger they grow, with the only external sign of their presence being the warping of space due to their gravity. In the process, a great deal of extremely hot gas is generated, and that gas emits hard x-rays. Now NASA's NuSTAR space telescope can find black holes by forming high-resolution images of the cosmos in hard x-rays. Read More
