NuSTAR Stares Deep into Hidden Lairs of Black Holes

Feature Story • July 6, 2015

Some of the "biggest and baddest" black holes around are buried under thick blankets of gas and dust. These monsters in the middle of galaxies are actively devouring material, but their hidden nature makes observing them a challenge. NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) recently caught a glimpse of five of these secluded beasts.

Star Explosion is Lopsided, Finds NASA's NuSTAR

News Release • May 7, 2015

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has found evidence that a massive star exploded in a lopsided fashion, sending ejected material flying in one direction and the core of the star in the other.

Strong Evidence For Coronal Heating Theory Presented at 2015 TESS Meeting

News Release • April 30, 2015

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.

NASA's NuSTAR Captures Possible 'Screams' from Zombie Stars

News Release • April 29, 2015

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.

Will the Real Monster Black Hole Please Stand Up?

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.

Sun Sizzles in High-Energy X-Rays

Feature Story • December 22, 2014

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.

NASA X-ray Telescopes Find Black Hole May Be a Neutrino Factory

News Release • November 13, 2014

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.

NASA's NuSTAR Telescope Discovers Shockingly Bright Dead Star

News Release • October 8, 2014

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.

Pulse of a Dead Star Powers Intense Gamma Rays

Feature Story • September 16, 2014

When the most massive stars explode as supernovas, they don't fade into the night, but sometimes glow ferociously with high-energy gamma rays. What powers these energetic stellar remains?

Science Friday Podcast | Unraveling the Mysteries of Black Holes

Podcast • August 29, 2014

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.

NASA's NuSTAR Sees Rare Blurring of Black Hole Light

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.

Swiftly Moving Gas Streamer Eclipses Supermassive Black Hole

Feature Story • June 19, 2014

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.
