NASA Using NASA's Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away -- 10 times farther than previously possible. Astronomers have developed yet another novel way to use the 24-year-old space telescope by employing a technique called spatial scanning, which dramatically improves Hubble's accuracy for making angular measurements. The technique, when applied to the age-old method for gauging distances called astronomical...

Scientists Make The Most Precise Measurment Of Early Universe Yet
2014-04-08 07:50:37

Lawrence LeBlond for redOrbit.com - Your Universe Online Two recent studies of the early Universe using the Baryon Oscillation Spectroscopic Survey (BOSS), a component of the third Sloan Digital Sky Survey (SDSS-III), have made the most accurate measurement of the rate of expansion in the early Universe to date. BOSS has pioneered the use of quasars to map density variations in intergalactic gas at high redshifts to trace the structure of the young Universe. BOSS helps scientists chart...

WASHINGTON, April 3, 2014 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, catalogued as ACT-CL J0102-4915, and found it definitely lives up to its nickname -- El Gordo (Spanish for "the fat one"). http://photos.prnewswire.com/prnvar/20081007/38461LOGO By measuring how much the cluster's gravity warps images of galaxies in the distant background, a team of astronomers has calculated the cluster's mass to...

Dark Energy Hidden Behind Phantom Fields
2014-03-28 14:30:26

FECYT - Spanish Foundation for Science and Technology Quintessence and phantom fields, two hypotheses formulated using data from satellites, such as Planck and WMAP, are among the many theories that try to explain the nature of dark energy. Now researchers from Barcelona and Athens suggest that both possibilities are only a mirage in the observations and it is the quantum vacuum which could be behind this energy that moves our universe. Cosmologists believe that some three quarters of...

The Hubble Space Telescope IV Conference Celebrates With Unveiling Of New Artwork
2014-03-27 08:47:33

HUBBLE Last week researchers from around the world gathered at the Accademia dei Lincei in Rome for the Science with the Hubble Space Telescope IV conference. The event celebrated the history of Hubble’s extraordinary achievements, and looked to the future at what might yet be achieved and how the James Webb Space Telescope will build on our knowledge of the Universe. As part of this celebration artist Tim Otto Roth revealed a new artwork, Heaven’s Carousel, inspired by Hubble’s work...

Astronomers Discover The Earliest Echoes Of The Big Bang

Lee Rannals for redOrbit.com - Your Universe Online Astronomers publishing a paper in the journal Nature say they have found the first direct evidence that gravitational waves rippled through the early Universe during the inflation period. Scientists using the NASA-developed detector technology on the BICEP2 telescope at the South Pole found the strongest confirmation yet of cosmic inflation theories, which say the universe expanded by 100 trillion trillion times in less than the blink...

MONTREAL , March 7, 2014 /PRNewswire/ -- According to the Pantheory Research Organization, a new study of type 1a supernova data has concluded, for the first time, that dark energy probably does not exist. The paper is entitled "An Alternative Universe-Scale Analytic Metrology and Related Cosmological Model." The paper was published in the February 2014 issue of the journal of Applied Physics Research, by the Canadian Center of Science and Education. This new research study...

A Wide Range Of Masses Observed In Type Ia Supernovae
2014-03-04 13:06:14

Lee Rannals for redOrbit.com - Your Universe Online Astronomers, publishing a paper in the Monthly Notices of the Royal Astronomical Society, show how Type Ia supernovae have a range of masses. Scientists have been confident in knowing why Type Ia supernovae are all so much alike. Most of them assumed that carbon-oxygen white dwarf stars capture additional mass by stripping it from a companion star or by merging with another white dwarf. Scientists assumed this class of supernova were...

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.

The Virgo Cluster consists of galaxies at a distance of around 59 Mly away in the constellation Virgo. Containing between 1300 to 2000 galaxies the Virgo Cluster is the heart of the Local Supercluster. Its mass is estimated at 1.2 × 1015 M☉ out to 8 degrees of the cluster's center or a radius of about 2.2 Mpc. Most of the brighter galaxies in the cluster were discovered by Charles Messier in the late 1770's and early 1780's, including the giant elliptical Messier 87. Messier...

The Coma Cluster (Abell 1656), along with the Leo Cluster, is one of two major clusters compromising the Coma Supercluster. It contains over 1000 identified galaxies. Most of the galaxies in the center of the Coma Cluster are elliptical galaxies including both dwarf and giant. However the center is dominated by NGC 4874 and NGC 4889, two giant elliptical galaxies. The brightest galaxies are visible, a few degrees north of the galactic pole, with an amateur telescope larger than 20 cm. The...

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).

Sample Entry: Astronomy is the scientific study of stars, planets, comets, galaxies, and other phenomena that occur outside Earth's atmosphere (e.g. cosmic radiation). Astronomy deals with the evolution, physics, chemical makeup, meteorology, and motion of celestial objects, and also the formation of the universe. The word Astronomy comes from the Greek words astron (meaning "star") and nomos (meaning "law"). Astronomy is one of the oldest sciences. Since the dawn of man, people always...
