Latest Sagittarius constellation Stories
Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency's (ESA) Herschel spacecraft has revealed that the supermassive black hole in the center of our galaxy is about to get a taste of some hot molecular gas. Sagittarius A has a mass of about four million times that of our Sun and sits about 26,000 light-years away from us. It is a few hundred times closer to us than any other galaxy with an active black hole at its center, making it ideal for studying these...
WATCH VIDEOS: [Panning Across NGC 6559] | [Zooming In On NGC 6559] John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The Danish 1.54-metre telescope located at ESO’s La Silla Observatory in Chile has released a new image of the star-forming region NGC 6559. Located relatively nearby, a mere 5000 light-years from Earth, NGC 6559 is found in the constellation of Sagittarius (The Archer). The nebula is only a few light years across, a stark contrast to its more well-known...
[ Video 1 ] | [ Video 2 ] | [ Video 3 ] Lee Rannals for redOrbit.com - Your Universe Online A new image released by the European Space Observatory (ESO) illustrates the bright star cluster NGC 6520, located in one of the richest star fields in the sky. Astronomers using ESO's La Silla Observatory in Chile took advantage of the Wide Field Imager on the telescope to snap the image. The image not only shows off NGC 6520, but also its neighbor, the strange dark cloud known as Barnard...
Rayshell Clapper for redOrbit.com - Your Universe Online Astronomers may now have a way to image the center of the Milky Way galaxy, which has posed problems to scientists trying to image all of its exotic features. Soon they may be able to learn more about the features of the center of the Milky Way and learn more about where they are located in the galaxy by use of radio waves. Prior to the discovery of radio waves, astronomers primarily used optical waves like the X-ray and infrared...
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 150...
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 principal...
WASHINGTON, Oct. 23, 2012 /PRNewswire-USNewswire/ -- NASA's newest set of X-ray eyes in the sky, the Nuclear Spectroscopic Telescope Array (NuSTAR), has caught its first look at the giant black hole parked at the center of our galaxy. The observations show the typically mild-mannered black hole during the middle of a flare-up.

Lee Rannals for redOrbit.com - Your Universe Online Scientists have determined that the black hole in the middle of the Milky Way is getting ready to devour an approaching cloud of dust and gas. The researchers used a supercomputer simulation to determine that the cloud, known as G2, could possibly survive the encounter with the black hole, but its surviving mass would be torn apart and shaped differently. They came up with six simulations using Cosmos++ computer code, requiring more...
Lee Rannals for redOrbit.com – Your Universe Online Astronomers, using the Keck Observatory, have found the star they need to test Einstein's theory about the fabric of space-time. UCLA astronomers said they have discovered a star that orbits the enormous black hole at the center of our Milky Way that will help discover whether Albert Einstein was right in his fundamental prediction of how black holes warp space and time. The star, S0-102, orbits the black hole every 11-and-a-half...
[ Watch the Video ] Lee Rannals for redOrbit.com According to a post by the European Research Media Center, the black hole in the center of our galaxy is about to meet up with a giant gas cloud in 2013. The celestial spectacle will provide astronomers with a prime front-row seat of Sagittarius A passing by a gas cloud at only 36 light-hours, or about 24 million miles. Although the distance between the two celestial objects seems far, it is extremely close in astronomical...

Trifid Nebula -- Discovered by Charles Messier in 1764. Charles Messier discovered this object on June 5, 1764, and described it as a cluster of stars of 8th to 9th magnitude, enveloped in nebulosity. The Trifid Nebula M20 is famous for its three-lobed appearance. This may have caused William Herschel, who normally carefully avoided to number Messier's objects in his catalog, to assign four different numbers to parts of this nebula: H IV.41 (cataloged May 26, 1786) and H V.10, H V.11,...
Lagoon Nebula -- The Lagoon Nebula was discovered by Le Gentil in 1747. As often for diffuse nebulae, the cluster of young stars which has formed from the nebula's material was discovered first. In this case the young open cluster NGC 6530 in the Eastern half of M8 was discovered by Flamsteed about 1680, and again seen by De Ch'seaux in 1746, before Le Gentil found the nebula in 1747. Abbe Nicholas Louis de la Caille has cataloged it in his 1751-52 compilation as Lacaille III.14....
