Bright Flare In A Black Hole
2012-11-06 19:14:34

Lee Rannals for redOrbit.com — Your Universe Online A team of scientists say they have detected the brightest flare ever observed in our galaxy's black hole. The astronomers used NASA´s Chandra X-Ray Observatory to detect the brightest flare ever observed from Sagittarius A*. The black hole is considered to be low-key, emitting very little energy for its size. It gives off about as much energy as the sun, despite it being 4 billion times as massive. The recent flare is...

Chandra Eyes Mini Supermassive Black Hole
2012-10-25 07:19:58

April Flowers for redOrbit.com - Your Universe Online NASA's Chandra X-ray Observatory, along with other observatories, has identified one of the lowest mass supermassive black holes ever observed in the middle of a galaxy that one would not expect to harbor this type of beast. This suggests that this black hole, while related to its supermassive cousins, may have a different origin. Located in the middle of the spiral galaxy NGC 4178, the black hole is shown in the image from the Sloan...

NuSTAR Picks Up First Black Hole X-ray Flare Up
2012-10-24 10:43:45

Lee Rannals for redOrbit.com — Your Universe Online NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has spotted its first flare from Milky Way's black hole. The new telescope, launched June 13, is the only telescope capable of producing focused images of the highest-energy X-rays, and NASA said it has caught its first look at the black hole. "We got lucky to have captured an outburst from the black hole during our observing campaign," Fiona Harrison, the mission's...

Planetary Nebula Survey By Chandra
2012-10-11 05:21:48

April Flowers for redOrbit.com - Your Universe Online An international team of astronomers using NASA's Chandra X-ray Observatory has created a sweeping new survey of dying stars — or planetary nebula — in the neighborhood of the Sun. The resulting X-ray images shed light on the violent "end game" of a Sun-like star's life. Led by Joel Kastner from the Rochester Institute of Technology (RIT), the team won seven days of observation time with Chandra in 2011-2012 to survey and...

Cosmic Superbubble Shows Its Bright Side
2012-08-31 11:01:49

April Flowers for redOrbit.com - Your Universe Online NASA has released a hauntingly beautiful composite image showing a superbubble in the Large Magellanic Cloud (LMC). The LMC is a small satellite galaxy of the Milky Way located about 160,000 light years from Earth. A superbubble is a cavity, filled with 106 Kelvin gas blown into the interstellar medium by multiple supernovae and stellar winds, hundreds of light years across. These cavities are carved out of the surrounding gas by the...

Chandra Finds Young Supernova Remnant Spitting Out X-rays
2012-07-31 05:18:12

April Flowers for redOrbit.com - Your Universe Online In a galaxy not that far away, astronomically speaking at least, researchers using NASA's Chandra X-ray Observatory have detected the first x-rays emitted by the debris of a young supernova, SN 1957D. 15 million light years from Earth, in the M83 spiral galaxy, SN 1957D is one of only a few supernova located outside the Milky Way galaxy that is detectable in both radio and optical wavelengths, decades after the explosion itself was...

X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...

Chandra X-ray Observatory -- NASA's Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Columbia on July 23, 1999, is the most sophisticated X-ray observatory built to date. Chandra is designed to observe X-rays from high-energy regions of the universe, such as the remnants of exploded stars. The Observatory has three major parts: (1) the X-ray telescope, whose mirrors focus X-rays from celestial objects; (2) the science instruments which record the X-rays so...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
