Newly Developed Holographic Process Uses Image-stabilized X-ray Camera
2014-01-07 11:40:04

Helmholtz-Zentrum Berlin A team headed by Stefan Eisebitt has developed a new X-ray holography method that will enable snap-shots of dynamic processes at highest spatial resolution. The efficiency of the new method is based on a X-ray focusing optics being firmly fixed to the object to be imaged. While this approach initially provides a blurry image, this can be focused in the computer based on the hologram information. At the same time, the rigid connection between the object and the...

Astronomers Search For Cause Of Massive Star Formation
2013-12-21 04:25:12

redOrbit Staff & Wire Reports - Your Universe Online In an attempt to determine why massive stars – those with at least eight times the mass of our Sun – grow so much larger than most other stars in our galaxy, astronomers used the ALMA telescope to examine the cores of Infrared Dark Clouds roughly 10,000 light-years away. Infrared Dark Clouds are located in the direction of the constellations of Aquila and Scutum, and they are among the darkest, densest and coldest clouds in...

New Star Counting App Asks Citizen Scientists To Map The Skies
2013-12-20 15:46:51

Lee Rannals for redOrbit.com - Your Universe Online German researchers are asking citizen scientists to use an app to help them count the stars in their city to see how light pollution affects what shows up in the night sky. Scientists developed the “Loss of the Night" app to measure how the brightness of the sky changes over time, as lighting technologies change. The app has been expanded to support 11 languages to gather data from as many regions as possible. “Since the app...

New Insights Into Cosmic Phenomena Provided By Swift Satellite
2013-12-17 05:07:02

redOrbit Staff & Wire Reports - Your Universe Online By analyzing data collected by NASA’s Swift robotic spacecraft, astronomers from the University of Leicester have reportedly discovered the location of nearly 100,000 previously unknown cosmic X-ray sources. The research team studied eight years’ worth of observations collected during the Swift Gamma-Ray Burst Mission to compile a catalog of major celestial X-ray sources – a list that includes more than 150,000 high-energy...

DARPA Is At Work Developing The Latest High-Tech Spy Satellite
2013-12-10 13:19:11

[ Watch the video: DARPA MOIRE Concept Video ] Lee Rannals for redOrbit.com - Your Universe Online DARPA says it has plans to develop an ultimate spy satellite capable of viewing 40 percent of the Earth’s surface at once. The Membrane Optical Imager for Real-Time Exploitation (MOIRE) space telescope will be launched as a tightly packed cluster of petals 20 feet in diameter, helping it stretch out to 68 feet across. It will record the Earth’s surface with high resolution imagery,...

Starburst Galaxy M82 - An Up Close And Personal Look
2013-12-10 04:23:24

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have managed to get an up close and personal look at the nearby starburst galaxy M82, detecting concentrations of dense molecular gas surrounding regions of intense star formation and streams of material exiting the galaxy’s disk, the National Radio Astronomy Observatory (NRAO) announced Monday. The new data comes courtesy of the high-frequency Robert C. Byrd Green Bank Telescope (GBT), the world's largest,...

2013-12-09 19:29:17

ESO The ESO Council, at its meeting this week in Garching, has approved the appointment of Rob Ivison as the next ESO Director for Science. Ivison will take up his post on 31 March 2014. Ivison is currently a Senior Research Fellow at the University of Edinburgh's Institute for Astronomy, based at the Royal Observatory Edinburgh, and holds an Advanced Grant from the European Research Council. He has a strong and broad track record in astronomy, with expertise covering optical, infrared,...

Research Quality X-rays Could Have Widespread Applications
2013-11-25 08:27:00

University of Nebraska-Lincoln Using a compact but powerful laser, a research team at the University of Nebraska-Lincoln has developed a new way to generate synchrotron X-rays. Although the high quality of synchrotron X-rays make them ideal for research ranging from the structure of matter to advanced medical images, access to the technology has been limited until now. Most traditional synchrotron X-ray devices are gigantic and costly, available only at a few sites around the world....

Cosmic Deception: One Galaxy Is Actually Two

Alan McStravick for redOrbit.com - Your Universe Online My fifth grade teacher, Elizabeth Titterton, was responsible for teaching me the order of the planets in our solar system. A simple pneumonic ingrained in me an immutable truth that I carry to this day. "My Very Excellent Mother Just Served Us Nesselrode Pie." Of course, the ‘P’, representing Pluto, has been recast as simply a ‘minor’ planet, somehow stripping me of the concept of absolute truth for the rest of my life. And...

Throes Of Stellar Birth Revealed As Never Before
2013-11-12 04:04:45

April Flowers for redOrbit.com - Your Universe Online The bubbly birth of a bouncing baby star has been revealed by observations from NASA's Spitzer Space Telescope and the newly completed Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. For the well-studied object known as HH 46/47, the observations have revealed the mechanisms of stellar birth as never before seen. HH, or Herbig-Haro, objects form when jets pushed out by newborn stars collide with material surrounding...

Radio telescopes, used in tracking and collecting data from satellites and space probes, are a form of directional radio antenna used in radio astronomy. They operate on the radio frequency portion of the electromagnetic spectrum where they detect radio sources. Radio telescopes are large parabolic antennas used singly or in an array and are located far from major centers of population in order to avoid electromagnetic interference. Karl Guthe Jansky built the first radio antenna used to...

A telescope, designed to aid the observation of remote objects, collects some form of electromagnetic radiation (such as visible light). The Netherlands developed the first known practical telescope in the 17th century. The term "telescope" was termed in order to describe Galileo's instruments in 1611. However, Galileo was not the inventor of the telescope. It was Hans Lippershey, Zacharias Janssen, and Jacob Metius who are credited with the creation of the telescope. In 1668, Isaac Newton...

Sample Entry: Astronomy is the scientific study of stars, planets, comets, galaxies, and other phenomena that occur outside Earth's atmosphere (e.g. cosmic radiation). Astronomy deals with the evolution, physics, chemical makeup, meteorology, and motion of celestial objects, and also the formation of the universe. The word Astronomy comes from the Greek words astron (meaning "star") and nomos (meaning "law"). Astronomy is one of the oldest sciences. Since the dawn of man, people always...
