Le mât est soumis à des contraintes thermiques importantes lors du passage du télescope du côté jour au côté nuit de son orbite qui induisent des déformations de la géométrie de l'ensemble constitué par l'optique et les détecteurs situés au plan focal. Part of HuffPost Science. As the matter is dragged onto the neutron star, it heats up and glows with X-rays. The newly discovered Jupiter-size object may have arrived long after the star died. "Now, we find that the second source of bright X-rays in M82 isn't a black hole at all. Pour cette raison les rayons X, qui arrivent sur une surface réfléchissante, ne sont pas renvoyés par celle-ci comme la lumière visible mais la traversent. The research appeared Aug. 20 in the Astrophysical Journal. Copyright 2013 SPACE.com, a TechMediaNetwork company. NuSTAR did not initially set out to study the two ULXs in M82. But your state may let you vote during a designated early voting period.

"We took it for granted that the powerful ULXs must be massive black holes," said lead study author Matteo Bachetti, of the University of Toulouse in France. Until now, all ULXs were thought to be black holes. The NuSTAR (Nuclear Spectroscopic Telescope Array) mission has deployed the first orbiting telescopes to focus light in the high energy X-ray (3 - 79 keV) region of the electromagnetic spectrum. Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. En novembre de la même année, la NASA sélectionne NuSTAR et quatre autres propositions pour une première étude de faisabilité de cinq mois. The NuSTAR Telescope Is Rapidly Changing What We Know About the Universe.
WASHINGTON, Oct. 8, 2014 /PRNewswire-USNewswire/ -- Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. Plus le rayon X est dur, c'est-à-dire énergétique, plus l'incidence doit être faible. Astronomers had been observing a recent supernova in the galaxy when they serendipitously noticed pulses of bright X-rays coming from the ULX known as M82 X-2. L'observation des sources de rayons situées à l'extérieur de notre galaxie en particulier de la zone XBoötes (8,5 deg²) det de la zone GOODS (300 arc-minutes²). Like black holes, neutron stars are the burnt-out cores of exploded stars, but puny in mass by comparison.

In the instruments' combined data, this nearby dwarf galaxy looks like a fiery, circular explosion. NuSTAR a comme objectif secondaire l'étude des rayons X durs émis par la couronne solaire durant les éruptions solaires ainsi que la détection des axions, particules hypothétiques qui peuvent être émises par le Soleil[9].
