Jason Bardi, American Institute of Physics Researchers at Harvard-Smithsonian Center for Astrophysics Finger Silicon-Capped Hydrocarbons as Possible Source of Mysterious "Diffuse Interstellar Bands" Over the vast, empty reaches of interstellar space, countless small molecules tumble quietly though the cold vacuum. Forged in the fusion furnaces of ancient stars and ejected into space when those stars exploded, these lonely molecules account for a significant amount of all the carbon,...

Caltech's Cosmic Web Imager Directly Observes "Dim Matter"
2014-04-30 03:53:16

Cynthia Eller, California Institute of Technology Caltech astronomers have taken unprecedented images of the intergalactic medium (IGM)—the diffuse gas that connects galaxies throughout the universe—with the Cosmic Web Imager, an instrument designed and built at Caltech. Until now, the structure of the IGM has mostly been a matter for theoretical speculation. However, with observations from the Cosmic Web Imager, deployed on the Hale 200-inch telescope at Palomar Observatory,...

Exploring Hidden Milky Way
2013-08-01 08:48:11

John P. Millis, PhD for redOrbit.com - Your Universe Online Understanding how the Milky Way formed is one of the central scientific questions in astronomy. However, given the scale and complexity of the galaxy, there is a lot to consider. One of the ways researchers have found to tell the story of our galaxy's history is to create a detailed stellar census, analyzing spectra of large numbers of stars. "A star's spectrum is a powerful tool for learning about the star - it tells us key...

Quasar Radiation Influences Galaxy Growth
2013-07-25 05:58:07

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists writing in The Astrophysical Journal have shed some new light on the universe's brightest objects - quasars. The team from Dartmouth University published details about discoveries based on 10 quasar observations. They wrote about the power of quasar radiation, which can reach out for many thousands of light years to the limits of the quasar's galaxy. Astrophysicists Ryan Hickox and Kevin Hainline and colleagues used...

Project 1640 Imaging System Allows Astronomers To See Distant Exoplanets
2013-03-13 21:39:14

Brett Smith for redOrbit.com — Your Universe Online Using a state-of-the-art telescopic imaging system, astronomers are now able to see planets that orbit distant stars, known as exoplanets, more easily and in greater detail, according to a report in the Astrophysical Journal. Scientists gather information from distant planets via the light they radiate, referred to as their spectra, and previously, astronomers have only been able to analyze planets as they pass in front of, or...

Evidence Of Gas Flow As Galactic Fuel Found
2013-01-12 08:28:26

redOrbit Staff & Wire Reports — Your Universe Online Thanks to observations obtained using the Hubble Space Telescope, researchers have discovered direct, empirical evidence of the existence of gas flows that are consumed by galaxies as fuel. A team led by Nicolas Lehner, research associate professor at the University of Notre Dame, studied data collected by the telescope´s two ultraviolet spectrographs, the Cosmic Origins Spectrograph and the Space Telescope Imaging...

Astrochemistry Entering New Era As Technologies, Techniques Move Ahead
2012-09-20 12:59:12

[WATCH VIDEO] Lee Rannals for redOrbit.com — Your Universe Online A new field of chemistry is arising through the development of technologies, and it ensures that scientists do not just set their sights on things of this Earth. Astrochemistry is entering a new era with the development of the Atacama Large Millimeter/submillimeter Array (ALMA) telescope and new laboratory techniques. Scientists were able to improve and speed up the process of identifying the "fingerprints" of...

RIT professor co-authors Nature article and Gemini Observatory's 1,000th paper The discovery of 13 diffuse interstellar bands with the longest wavelengths to date could someday solve a 90-year-old mystery. Astronomers have identified the new bands using data collected by the Gemini North telescope of stars in the center of the Milky Way. Nature reports on its website today findings that support recent ideas about the presence of large, possibly carbon-based organic...

[ Watch the Video ] New VLT observations chart timeline of deionization Scientists have used ESO´s Very Large Telescope to probe the early Universe at several different times as it was becoming transparent to ultraviolet light. This brief but dramatic phase in cosmic history – known as deionization – occurred around 13 billion years ago. By carefully studying some of the most distant galaxies ever detected, the team has been able to establish a timeline for deionization...

As of 2009, JKCS 041 is a group of galaxies with the distinction of being the farthest away group from Earth ever observed. Seen at redshift 1.9, it is estimated to be 10.2 billion light years away. The cluster is located within the constellation Cetus at a photometrically determined redshift of z=1.9 at right ascension 2h 26m 44s declination -04° 41"² 37"³ (J2000.0).

Doppler Effect -- The Doppler effect is the apparent change in frequency or wavelength of a wave that is perceived by an observer moving relative to the source of the waves. For waves, such as sound waves, that propagate in a wave medium, the velocity of the observer and the source are reckoned relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from both motion of the source and motion of the observer. Each of these effects is analyzed...
