Professional And Amateur Astronomers Join Together

NASA Long before the term "citizen science" was coined, the field of astronomy has benefited from countless men and women who study the sky in their spare time. These amateur astronomers devote hours exploring the cosmos through a variety of telescopes that they acquire, maintain, and improve on their own. Some of these amateur astronomers specialize in capturing what is seen through their telescopes in images and are astrophotographers. What happens when the work of amateur...

Observations by two of the European Space Agency's space observatories have provided a multi-wavelength view of the mysterious galaxy Centaurus A. The elliptical galaxy Centaurus A at visible, far-infrared and x-ray wavelengths. In visible light the galaxy appears as a ball of stars, with a thick lane of dust running across it. The far-infrared light shows the glow from jets of material emanating from near the black hole in the galaxy´s core. Also visible is a twisted disc of dust,...

The Star Factory: Observing Arp 220

The galaxy Arp 220 is home to several giant star clusters–about 10 million solar masses–that are twice as massive as any comparable star cluster in the Milky Way Galaxy. McMaster University's Christine Wilson is captivated by this turbulent galaxy that provides such a target-rich environment for watching stars form. The reason that star formation is going wild is that the galaxy is in the late stages of a merger between two larger galaxies. "This is a nearby look at a...

Image 1 - Astronomers Find Link To Early Universe And Today's Massive Galaxies

[ Video 1 ] | [ Video 2 ] Astronomers have found the strongest link ever between the most powerful bursts of star formation in the Universe, and the most massive galaxies found today. The galaxies saw the birth of new stars cut short, leaving them as massive galaxies of aging stars today, according to the new research. The astronomers also found that the emergence of supermassive black holes played a role in causing the sudden end to the starburst. Astronomers used the LABOCA...

Image 1 - Fermi Census Highlights Cosmic Mysteries

  Every three hours, NASA's Fermi Gamma-ray Space Telescope scans the entire sky and deepens its portrait of the high-energy universe. Every year, the satellite's scientists reanalyze all of the data it has collected, exploiting updated analysis methods to tease out new sources. These relatively steady sources are in addition to the numerous transient events Fermi detects, such as gamma-ray bursts in the distant universe and flares from the sun. Earlier this year, the Fermi team...

NASA's Wide-field Infrared Survey Explorer has captured a new view of two companion galaxies -- a somewhat tranquil spiral beauty and its rambunctious partner blazing with smoky star formation. The unlikely pair, named Messier 81 and Messier 82, got to know each other a lot better during an encounter that occurred a few hundred million years ago. As they swept by each other, gravitational interactions triggered new bursts of star formation. In the case of Messier 82, also known as the Cigar...

A new Chandra X-ray Observatory image of Messier 82, or M82, shows the result of star formation on overdrive. M82 is located about 12 million light years from Earth and is the nearest place to us where the conditions are similar to those when the Universe was much younger with lots of stars forming. M82 is a so-called starburst galaxy, where stars are forming at rates that are tens or even hundreds of times higher than in a normal galaxy. The burst of star birth may be caused by a close...

Every cook knows the ingredients for making bread: flour, water, yeast, and time. But what chemical elements are in the recipe of our universe? Most of the ingredients are hydrogen and helium. These cosmic lightweights fill the first two spots on the famous periodic table of the elements. Less abundant but more familiar to us are the heavier elements, meaning everything listed on the periodic table after hydrogen and helium. These building blocks, such as iron and other metals, can be found...

Back in June 1991, just before the launch of NASA's Compton Gamma-Ray Observatory, astronomers knew of gamma rays from exactly one galaxy beyond our own. To their surprise and delight, the satellite captured similar emissions from dozens of other galaxies. Now its successor, the Fermi Gamma-ray Space Telescope, is filling in the picture with new finds of its own."Compton showed us that two classes of active galaxies emitted gamma rays -- blazars and radio galaxies," said Luigi Foschini at...

ESA's space-borne X-ray observatory, XMM-Newton, has carried out an exclusive observation of the galaxy Messier 82, for the "˜100 Hours of Astronomy' cornerstone project for the International Year of Astronomy 2009. The observatory was featured in the "˜Around the World in 80 Telescopes' live webcast last week. This European space telescope has been studying the sky in X-ray, optical and ultraviolet wavelengths simultaneously, since its launch in December 1999. The image...

Word of the Day
  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
