ESA Shutting Down Planck Space Telescope
2013-10-18 16:29:49

Brett Smith for redOrbit.com – Your Universe Online After for four years surveying the Universe for the European Space Agency (ESA), the Planck space telescope’s Low Frequency Instrument will be turned off on Saturday, having completed its science operations on October 3. The telescope’s High Frequency Instrument ended operation in January 2012, after conducting five all-sky surveys. With some operational loose ends still to tie up, Planck will finally be switched off next week....

Higgs Boson Dark Energy

John P. Millis, PhD for redOrbit.com - Your Universe Online For the better part of two decades, the greatest fundamental question facing physics and cosmology has been, quite simply, what is dark energy? Detailed observations of galaxies in our Universe reveal the expansion of the Universe is accelerating. Even after accounting for all of the normal matter, radiation, and even the theorized dark matter out there, there still simply isn't enough "stuff" to explain the dynamics of the...

3D Map Of The Large-Scale Structure Of The Universe Released
2013-08-08 13:58:29

Subaru Telescope An international team led by astronomers from Kyoto University, the University of Tokyo and the University of Oxford has released its first version of a 3D map of the Universe from its FastSound project (Note 1), which is surveying galaxies in the Universe over nine billion light years away. Using the Subaru Telescope's new Fiber Multi-Object Spectrograph (FMOS, Note 2), the team's 3D map includes 1,100 galaxies and shows the large-scale structure of the Universe nine...

Cosmic Microwave Background Radiation Data Allows Furthest Look Back Through Time
2013-08-08 04:23:16

April Flowers for redOrbit.com - Your Universe Online The best way to solve a mystery, as any detective can tell you, is to revisit the scene where it began and look for clues. Scientists, searching for the mysteries of our universe, are trying to go back as far as they can to the Big Bang. Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) conducted a new analysis of cosmic microwave background (CMB) radiation data to take the furthest look back yet. This look - 100...

Andromeda Galaxy Image Processed By The HSC Data Analysis Software
2013-08-06 11:44:39

Kavli Institute for the Physics and Mathematics of the Universe Today, researchers at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) released the first image of the Andromeda Galaxy (M31) processed with the data analysis software developed for the Subaru Telescope's Hyper Suprime-Cam (HSC). The HSC project's 'first light' was announced last week (A New View on the Origin of Dark Matter and Dark Energy - Image of M31 Heralds the Dawn of HSC). Researchers at...

New Weapon Hunt For Dark Matter Energy
2013-08-02 13:06:59

John P. Millis, PhD for redOrbit.com - Your Universe Online The search for dark matter - and the even more mysterious dark energy - has both captivated and frustrated the minds of cosmologists and astronomers. There are the obvious reasons: by definition these phenomenon are difficult, if not impossible, to observe directly, and their effects can often be so subtle that making precise enough measurements proves a technical challenge. To overcome these difficulties, a team from the...

“How to Understand the True Cosmos” aims to dispel misconceptions in astrophysics. Massachusetts (PRWEB) July 19, 2013 The rapid pace of scientific advancement in the field of astrophysics, and the new discoveries in the field and its sheer complexity has resulted in the obsolescence of many theories and models previously used to explain the nature of the universe and the celestial bodies within its expanse. With How to Understand the True Cosmos, Dr. Sol Aisenberg aims to improve the...

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...

Dark Energy Survey Will Look For Supernovae
2013-07-01 18:32:12

John P. Mills, Ph.D. for redOrbit.com - Your Universe Online The greatest cosmological puzzle of the 21st century continues to be to measure, characterize and understand the source of dark energy, the apparent force that is driving the accelerating expansion of the Universe. One of the problems is that in order to make accurate measurements of the expansion rate, astronomers must measure the motions of distant galaxies, some near the very edge of the known Universe. At such great...

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...

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.

Quintessence (Dark Energy) -- Quintessence or dark energy is a hypothetical form of energy postulated to exist in order to explain observations of an accelerating universe. This energy would act like a vacuum pressure, pushing things apart. Other attempts to explain these recent observations involve a non-zero cosmological constant, which has the same effect. Indeed, sometimes quintessence is said to result in a non-zero cosmological constant, and conversely a non-zero cosmological...

Wilkinson Microwave Anisotropy Probe (WMAP) -- The Wilkinson Microwave Anisotropy Probe (WMAP) was launched on June 30, 2001 at 3:46 p.m. EDT at Cape Canaveral Air Force Station, Florida, USA. The goal of WMAP was to map out minute differences in the Cosmic Microwave Background (CMB) radiation which would help test theories of the nature of the universe. On February 11, 2003, the public relations group from NASA made a press release regarding the age and composition of the universe....
