Explore free tools to help you learn and teach more about the Universe that all of us inhabit. Our ability to tune in the more exotic radio waves has grown in recent decades. Chandra X-ray Observatory is one of the four NASA’s series of Great Observatory satellites. A new form of radiation was discovered in 1895 by Wilhelm Roentgen, a German physicist. Abell 2384.jpg 864 × 639; 476 KB. X-rays also have the ability to knock electrons loose from atoms. X-ray telescopes like Chandra can see superheated matter that is swirling toward the event horizon of a black hole. Instead of slowing down after the Big Bang, the expansion of the Universe was found to be accelerating. The NHFP is one of the highlights of NASA's pursuit of excellence in astrophysics. These bizarre objects are found across the Universe -- within double star systems and at the centers of galaxies where giant black holes grow. Chandra The Chandra X-ray Observatory is NASA’s flagship X-ray observatory, providing essential data on everything from the environment surrounding newborn stars … NASA's Chandra X-ray Observatory has taken space-based images of the universe in X-ray light since 1999. During each orbit of the Earth, Chandra travels one-third of the way to the Moon. Chandra's unusual orbit was achieved after deployment by a built-in propulsion system which boosted the observatory to a high Earth orbit. NASA's Chandra X-ray Observatory is a telescope specially designed to detect X-ray emission from very hot regions of the Universe such as exploded stars, clusters of galaxies, and matter around black holes. A substantial body of evidence indicates that it cannot be baryonic matter, i.e., protons and neutrons. The Chandra Source Catalog (CSC) is the definitive catalog of X-ray sources detected by the Chandra X-ray Observatory.Version 2.0 (CSC2) is the second major release of the catalog, and represents a significant improvement with respect to version 1.1 … The Chandra X-ray Observatory is the U.S. follow-on to the Einstein Observatory.

"Chandra X-ray Observatory" 1 An astronomical/telescope satellite somewhat similar to Chandra/CXO/AXAF is shown in an early-design stage , most likely due to the pre-launch date of these items, when the design was not finalized. 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 that X-ray images can be produced and analyzed; and (3) the spacecraft, which provides the environment necessary for the telescope and the instruments to work. The Chandra X-ray Observatory. Our ability to tune in the more exotic radio waves has grown in recent decades. Since the Earth's atmosphere absorbs the vast majority of X-rays, they are not detectable from Earth-based telescopes; therefore space-based tele… Because X-rays are absorbed by Earth's atmosphere, Chandra must orbit above it, up to an altitude of 139,000 km (86,500 mi) in space. The word light usually makes one think of the colors of the rainbow or light from the Sun or a lamp. For historical reasons having to do with measuring distances to nearby stars, professional astronomers use the unit of parsecs, with one parsec being equal to 3.26 light years. The Chandra X-ray Observatory (CXO), previously known as the Advanced X-ray Astrophysics Facility (AXAF), is a Flagship-class space telescope launched aboard the Space Shuttle Columbia during STS-93 by NASA on July 23, 1999. Chandra has traced the separation of dark matter from normal matter in the collision of galaxies in a cluster and is contributing to both dark matter and dark energy studies. The third of NASA’s four Great Observatories, Chandra launched on the Space Shuttle Columbia in July, 1999 and is currently operating well beyond its five-year expected lifetime. This orbit, which has the shape of an ellipse, takes the spacecraft more than a third of the way to the moon before returning to its closest approach to the Earth of 9,942 miles. The Chandra X-ray Observatory, with its Inertial Upper Stage and support equipment, is the largest and heaviest payload ever launched by the Space Shuttle. The Chandra X-Ray Observatory is a NASA telescope that looks at black holes, quasars, supernovas, and the like – all sources of high energy in the universe. In general the smaller the wavelength, the higher the energy of the radiation. The Chandra spacecraft carries a high resolution mirror, two imaging detectors, and two sets of transmission gratings. CHANDRA X-RAY OBSERVATORY CHANDRA X-RAY OBSERVATORY Spacey Maze Help Chandra fi nd the supernova. This mysterious radiation had the ability to pass through many materials that absorb visible light. Depending on which detector is used, very detailed images or spectra of the cosmic source can be made and analyzed. Listen to a Public Radio Hour special on Chandra The other three are Hubble Space Telescope, Compton Gamma Ray … The Chandra X-ray Observatorys operating orbit takes it 200-times higher than the Hubble Space Telescope. Data sonification allows users to be able to hear information from cosmic objects as well as see it. The enormous hot cloud of stellar debris stretches across 40 light The energy of the radiation depends on the distance between the crests (the highest points) of the waves, or the wavelength. This light, however, is only one type of electromagnetic radiation. The scientific instruments on-board the satellite include a high-resolution camera that records the X-ray images and a spectrometer that determines the energy level of the X-rays.

'shining or moon'), also known as Soma , is the Hindu god of the Moon, and is associated with the night, plants and vegetation. Chandra (Sanskrit: चन्द्र, romanized: Candra, lit. The favored model is that dark matter is mostly composed of exotic particles formed when the universe was a fraction of a second old. Such particles, which would require an extension of the so-called Standard Model of elementary particle physics, could be WIMPs (weakly interacting massive particles), or axions, or sterile neutrinos. At the close of the 20th century, our perception of the Universe was jolted. Chandra was formerly known as AXAF, the Advanced X-ray Astrophysics Facility, but renamed by NASA in December, 1998. Chandra has revealed how black holes impact their environments, how they behave, and their role in helping shape the evolution of the cosmos. The nature of dark matter is unknown. Electromagnetic Spectrum and Chandra X-Ray Observatory The electromagnetic spectrum, extends from radio waves to gamma waves, from very low frequencies to extremely high frequencies. Deep surveys with the Chandra X-ray Observatory should reveal the cause of this glow. Chandra has imaged the spectacular, glowing remains of exploded stars, and taken spectra showing the dispersal of elements.
