Supernova Remnant Powered By Radioactive Decay Of Titanium
2012-10-18 04:20:39

April Flowers for redOrbit.com - Your Universe Online Radioactive titanium associated with supernova remnant 1987A has been directly detected by ESA's Integral space observatory. The glowing remnant around the exploded star has likely been powered by the decaying from this titanium for the last 20 years. The first space observatory that can simultaneously observe objects in gamma rays, X-rays and visible light, Integral's principal targets are violent explosions known as gamma ray...

Students from across Europe have been selected as the winners of the ESA´s ℠Explore the high-energy Universe´ competition. Secondary school students were invited to choose from four projects relating to ESA´s Integral gamma-ray observatory in which they were challenged to Observe, Research, Design, or Build. To participate, students took on the roles of engineers, scientists, and astronomers to explore the extreme and ever-changing high-energy Universe, including...

Image 1 - New Facets Of The Vela Pulsar Wind Nebula
2012-01-26 05:28:55

Astronomers studying the Vela pulsar wind nebula with ESA's INTEGRAL observatory have successfully resolved its morphology in the hard X-ray band, for the first time. This pulsar-powered nebula is the most extended individual source yet observed at these energies. The study exploited a special imaging technique to reveal a new component of the source that likely consists of highly energetic electrons that have escaped from the core of the nebula in the last few thousand years. One of the...

INTEGRAL Deciphers Diffuse Signature Of Cosmic-ray Electrons
2011-12-22 04:22:00

Astronomers exploiting six years worth of data from ESA's INTEGRAL mission have pinned down the individual processes contributing to the high-energy Galactic interstellar emission produced by cosmic-ray electrons. Deciphering each of the different physical mechanisms at play at hard X-ray and soft gamma-ray wavelengths represents a crucial step towards an increasingly detailed picture of the population of high-energy particles permeating the Milky Way. Cosmic rays are highly-energetic...

Vega To Fly ESA Experimental Reentry Vehicle
2011-12-17 05:30:41

The launch of ESA´s IXV Intermediate eXperimental Vehicle on Europe´s new Vega rocket is now in detailed planning, a major step towards the craft´s flight in 2014. Launched into a suborbital trajectory from Europe´s Spaceport in French Guiana, IXV will return to Earth as if from a low-orbit mission, to test and qualify new critical technologies for future reentry vehicles. It will attain an altitude of around 450 km, allowing it to reach a velocity of 7.5 km/s on...

Sentinel-2 Shapes Up For Testing
2011-11-30 12:19:29

An important milestone has been reached in the development of Sentinel-2. The satellite platform has been delivered to Germany where it will be integrated and tested with the various components that make up this sophisticated new craft to monitor Earth´s land surfaces. Manufactured by CASA in Spain, the platform has now been installed in the cleanroom at Astrium´s facilities in Friedrichshafen. The platform provides the structure on which to mount the payload instruments and...

Image 1 - Proba-1 Celebrates 10 Years Of Charting Earth's Radiation Belts
2011-11-08 08:43:43

ESA´s Proba-1 recently celebrated its tenth birthday in orbit. Kept busy as an Earth-observing mission, the microsatellite has also been building a detailed picture of changes in our planet´s radiation belts. Smaller than a cubic meter, the technology-testing Proba-1 was launched on 22 October 2001. Among the payloads was ESA´s SREM standard radiation environment monitor, which was turned on a week later. The size of a shoebox, the monitor records high-energy charged...

Gamma-Ray Astronomy -- Gamma-ray astronomy is the astronomical study of gamma rays. Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. Work by Feenberg and Primakoff in 1948, Hayakawa and Hutchinson in 1952, and, especially, Morrison in 1958 had led scientists to believe that a number of different processes which were occurring in the universe would result in gamma-ray emission. These...
