NuSTAR : NASA’s black hole hunter
NuSTAR is the first focusing hard X-ray telescope to orbit Earth. How are black holes distributed through the cosmos? To answer this question and to find more and more about the Black Hole NASA created a X-ray telescope which allows astronomers to study the universe in high energy X-rays. Nuclear Spectroscopic Telescope Array formally known as the NuSTAR launched in July 2012.
NuSTAR telescope uses a conical approximation to focus high energy X-rays from astrophysical sources, especially for nuclear spectroscopy. NuSTAR studies how the black holes generate and how it grow, how these processes affect to other host galaxies. NuSTAR study some of the hottest, densest and most energetic phenomena in the universe such as explosions of massive stars.
This mission delayed 5 times.
Telescope can examine space objects with unprecedented sensitivity by studying short-wavelength X-ray range and light in the high-energy. Images beamed back from NuSTAR will be 10 times sharper than current X-ray observatories in orbit. NuSTAR captured most sensitive solar portrait ever taken of our sun in high-energy X-rays. In addition it also captured the rare blurring of black hole light. It created the first map of radioactive material in a supernova remnant. And one of the recent phenomena it measured the spin rate of a black hole with a mass 2 million times that of our sun.
NuSTAR studies the origin of cosmic rays and the extreme physics around collapsed stars while responding to targets of opportunity including supernovae and gamma-ray bursts.
NASA’s this mission is opened a new window on the universe. However it was successfully completed its primary mission on July 31, 2014 and is now in its extended mission phase. It is expected to greatly exceed the performance of the largest ground-based observatories that have observed this region of the electromagnetic spectrum. NuSTAR complements astrophysics missions that explore the cosmos in other regions of the spectrum.
Hopefully one day it will answer several fundamental questions about the Universe including: How are black holes distributed through the cosmos? How were heavy elements forged in the explosions of massive stars? What powers the most extreme active galaxies? When did they start and stop feeding? What is the distribution of the gas and dust that both feed and hide the black holes?
The team expects to resolve more of the high-energy X-ray background over time.
