Thales Alenia Space Leads Euclid Construction
2013-07-08 11:23:02

ESA The construction of ESA's Euclid space mission to explore the 'dark Universe' will be led by Italy's Thales Alenia Space as prime contractor, beginning the full industrial phase of the project. The announcement follows that of last month when Astrium Toulouse was confirmed to build the payload module - the telescope and optical bench carrying the science instruments. Euclid will be launched in 2020 to explore the roles played by dark energy and dark matter in the evolution of the...

Euclid Dark Matter Mission Now In Development
2013-06-11 13:13:58

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency's (ESA's) Euclid module under development in France will be helping to explore dark energy and dark matter in the universe. Euclid will be launching in 2020 to help scientists better understand the evolution of the Universe since the Big Bang and its present accelerating expansion. Dark matter is invisible to normal telescopes, making it hard to study. However, the elusive subject plays a vital role in...

Black Holes Can Help Determine The Universe's Rate Of Expansion

Alan McStravick for redOrbit.com - Your Universe Online In 2011, the Nobel Prize for Physics was awarded to a trio of researchers. Adam Riess, Saul Perlmutter and Brian Schmidt were able to determine that the speed and scope of the expansion of the universe is not so uniform as once believed. This simple discovery threw the whole prospect of dating and measuring time in galaxies far from our own. However, this week saw a multi-national collaboration come together to detail just how we...

ESA's Planck Space Mission Creates Highly-Detailed Map Of The Universe
2013-03-21 12:44:54

Lee Rannals for redOrbit.com — Your Universe Online Using technologies contributed by NASA, the European Space Agency's (ESA) Planck space mission has provided the most accurate and detailed map made of the oldest light in the Universe. Results from Planck are giving a more detailed look into our Universe's history than ever before. The map suggests that the Universe is expanding more slowly and is 100 million years older than scientists previously thought. The data also shows...

Astronomers Create 3D Image Of Quasar
2013-02-19 04:09:56

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the Subaru Telescope recently obtained a three-dimensional view of a distant gravitationally-lensed quasar and discovered complex structures inside outflows coming from the nucleus. The team used the large telescope to observe quasar SDSS J1029+2623, which sits 10 billion light-years away from Earth in the constellation Leo. By using the gravitational lensing technique, astronomers were able to look at this far away...

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online In order to illuminate the darkness we turn to the light. Whether the sun, a lamp, or a candle, we rely on electromagnetic radiation to reveal the world, and indeed the Universe, around us. Everything that we see - every tree, every planet, and every star - we see because it emits, reflects, bends and focuses light to our eyes. Without the interaction of matter with light, we are blind. But what about matter that...

Dark Energy Theory Challenged
2013-01-10 09:15:38

[ Listen to the Podcast “The Search For Dark Energy” ] redOrbit Staff & Wire Reports - Your Universe Online A popular theory that relies on dark energy, thought to be the main contributor to the accelerating expansion of the Universe does not fit newly obtained data with regards to one fundamental constant — the proton to electron mass ratio. Rodger Thompson, a University of Arizona astronomy professor, disclosed his findings Wednesday at the American...

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Starting in early 2013 redOrbit will be launching a new podcast series called Your Universe Today, where we interview leading scientists about cutting-edge research in everything from space travel to the origins of our Universe. But we´re in the holiday spirit and couldn´t wait until January to unveil our new podcast project, so we´ve decided to give you a sneak peak of what´s to come. In the...

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

Cosmology -- area of science that aims at a comprehensive theory of the structure and evolution of the entire physical universe. Modern Cosmological Theories Present models of the universe hold two fundamental premises: the cosmological principle and the dominant role of gravitation. Derived by Hubble, the cosmological principle holds that if a large enough sample of galaxies is considered, the universe looks the same from all positions and in all directions in space. The second point...

Redshift -- Redshift is the phenomenon that the frequency of light when observed, under certain circumstances, can be lower than the frequency of light when it was emitted at the source. This usually occurs when the source moves away from the observer, as in the Doppler effect. More specifically, the term redshift is used for the observation that the spectrum of light emitted by distant galaxies is shifted to lower frequencies (towards the red end of the spectrum, hence the name) when...

Accelerating universe -- In the late 1990s, observations of type I supernova produced the unexpected result that the expansion of the universe appears to be accelerating. These observations appear more firm as new data has appeared. This means that the speed with which a distant galaxy recedes from us increases over time. If this trend continues, eventually we won't be able to see any other galaxies any more. This new theory of the end of the Universe has been called the Big Rip....

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
