The sun's surface is blisteringly hot at 10,340 degrees Fahrenheit -- but its atmosphere is another 300 times hotter. This has led to an enduring mystery for those who study the sun: What heats the atmosphere to such extreme temperatures? Normally when you move away from a hot source the environment gets cooler, but some mechanism is clearly at work in the solar atmosphere, the corona, to bring the temperatures up so high.

Peering into the heart of the Milky Way galaxy, NASA's Nuclear Spectroscopic Telescope Array has spotted a mysterious glow of high-energy X-rays that, according to scientists, could be the "howls" of dead stars as they feed on stellar companions.
News Release • February 19, 2015
NASA's Nuclear Spectroscopic Telescope Array and ESA’s XMM-Newton telescope are showing that fierce winds from a supermassive black hole blow outward in all directions -- a phenomenon that had been suspected, but difficult to prove until now.

The 2015 Rossi Prize has been awarded to Fiona Harrison, a professor at the California Institute of Technology in Pasadena, California, for her "groundbreaking work on supernova remnants, neutron stars and black holes enabled by NuSTAR".
News Release • January 8, 2015
A new high-energy X-ray image from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has pinpointed the true monster of a galactic mashup. The image shows two colliding galaxies, collectively called Arp 299, located 134 million light-years away. Each of the galaxies has a supermassive black hole at its heart.

For the first time, a mission designed to set its eyes on black holes and other objects far from our solar system has turned its gaze back closer to home, capturing images of our sun. NASA's Nuclear Spectroscopic Telescope Array has taken its first picture of the sun, producing the most sensitive solar portrait ever taken in high-energy X-rays.

The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos. If confirmed, this would be the first time that scientists have traced neutrinos back to a black hole. The evidence for this came from three NASA satellites that observe in X-ray light: the Chandra X-ray Observatory, the Swift gamma-ray mission, and the Nuclear Spectroscopic Telescope Array.

NuSTAR featured in Discovery Channel documentary called 'The Science of Interstellar'. Matthew McConaughey narrates this behind-the-scenes look at the epic voyage to deep space depicted in the movie Interstellar. Director Christopher Nolan worked with top physicists to create a realistic trip to distant solar systems.

Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar - a dense stellar remnant left over from a supernova explosion - ever recorded. The discovery was made with NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR.
Announcement • October 6, 2014
NASA will host a news teleconference at 10 a.m. PDT (1 p.m. EDT) Wednesday, Oct. 8, to announce new findings from its Nuclear Spectroscopic Telescope Array (NuSTAR) mission. The results describe an unusual source of X-rays that will leave theorists scratching their heads, but also will help astronomers learn more about how black holes and galaxies are formed.

Peering into supermassive black holes and picking through the remains of exploded stars is among the detective work the NuSTAR telescope performs. Launched in June 2012, the comparatively small telescope uses high energy x-rays to penetrate dust and gas to get a clear look at some of the densest, hottest regions of the universe, says Fiona Harrison.
News Release • August 12, 2014
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding a supermassive black hole. A compact source of X-rays that sits near the black hole, called the corona, has moved closer to the black hole over a period of just days.

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, a premier black-hole hunter among other talents, has finished up its two-year prime mission, and will be moving onto its next phase, a two-year extension.

Astronomers have discovered strange and unexpected behaviour around the supermassive black hole at the heart of the galaxy NGC 5548. The international team of researchers detected a clumpy gas stream flowing quickly outwards and blocking 90 percent of the X-rays emitted by the black hole. This activity could provide insights into how supermassive black holes interact with their host galaxies.

The 2014 NASA astrophysics division senior review panel has ranked NuSTAR second among the nine operating missions that were considered for extended operations. NASA has responded to the independent panels recommendations by approving continued operations through 2016 including the implementation of a Guest Observer Program that will begin in 2015. Details about the program will be available this summer.
