Author Richard Panek Wins 2012 AIP Science Communication Awards For Science Writing
2012-10-11 08:12:40

The American Institute of Physics (AIP) has selected author Richard Panek as winner of this year´s AIP Science Communication Award in the Science Writing category for his book The 4% Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality. The selection committee praised the book for its excellent writing and accurate depictions of the process of scientific investigation. “The mysteries of cosmology easily capture the imagination,” said...

New Hubble Data Reveals Ancient Dusty Galaxies
2012-10-10 09:08:37

April Flowers for redOrbit.com - Your Universe Online Dust can be the bane of any good housekeeper or computer technician. However, it is an important building block for stars and planets, and astronomers need to understand how cosmic dust forms over time. This understanding is an integral step in figuring out the evolution of galaxies and the stars and planets that they´re made of. Assistant professor Steven Finkelstein, of the University of Texas at Austin, and his colleagues are...

Milky Way Larger Than Previously Thought
2012-10-06 07:49:29

redOrbit Staff & Wire Reports — Your Universe Online The mass of the Milky Way is approximately 20% larger than previously believed, scientists from the National Astronomical Observatory of Japan (NAOJ) have discovered. The NAOJ team, led by associate professor Mareki Honma, used measurements from radio telescopes, including Japan's VLBI (Very Long Baseline Interferometry) Exploration of Radio Astrometry or VERA device, to determine that the distance from the sun to the center...

The winners of a contest that encourages scientists and students across the globe to explore fundamental, big questions in astronomy and cosmology will present their proposals and essays in a joint conference Oct. 12-13 at the Franklin Institute in Philadelphia. The New Frontiers in Astronomy & Cosmology International Grant and Essay Competition, led by Donald G. York, the Horace B. Horton Professor in Astronomy & Astrophysics at the University of Chicago, will award more than $4...

“New Frontiers” Award For Work On “Origami Universe” Received By JHU Cosmologists
2012-10-04 14:36:08

Two Johns Hopkins University research scientists who use the Japanese art of paper folding, known as origami, as a metaphor for understanding the complexity of the cosmos have been named winners of an award through the “New Frontiers in Astronomy & Cosmology International Grant and Essay Writing Competition,” funded by the John Templeton Foundation. Mark Neyrinck and Miguel Aragón-Calvo, both of the Henry A. Rowland Department of Physics and Astronomy at the...

Spitzer Helps Measure The Universe
2012-10-03 20:20:38

Lee Rannals for redOrbit.com — Your Universe Online NASA's Spitzer Space Telescope has allowed astronomers to make the most precise measurement yet of the rate at which our universe is expanding. This expansion rate, also known as the Hubble Constant, is critical for understanding the age and the size of the universe. In the latest research, Spitzer took advantage of long-wavelength infrared light to make its new measurement. The newly refined value for the Hubble Constant,...

WASHINGTON, Oct. 3, 2012 /PRNewswire-USNewswire/ -- Astronomers using NASA's Spitzer Space Telescope have announced the most precise measurement yet of the Hubble constant, or the rate at which our universe is stretching apart. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The Hubble constant is named after the astronomer Edwin P. Hubble, who astonished the world in the 1920s by confirming our universe has been expanding since it exploded into being 13.7 billion years ago....

Hubble Reveals Deepest View  Ever Of The Universe
2012-09-26 05:09:28

April Flowers for redOrbit.com - Your Universe Online Researchers using the Hubble Telescope have assembled a new and improved portrait of our deepest-ever view of the Universe. The eXtreme Deep Field (XDF) photo was compiled by combining ten years worth of NASA and ESA Hubble Space Telescope observations taken of a patch of sky within the original Hubble Ultra Deep Field. The Hubble Ultra Deep Field is a small area of space in the Fornax (The Furnace) constellation created using Hubble...

Milky Way Surrounded By Halo
2012-09-24 19:28:01

Lee Rannals for redOrbit.com — Your Universe Online The Milky Way Galaxy is known for its spirals, as well as Earth's home in the cosmos, but now it will also be known as a galaxy that features a halo. Astronomers using NASA's Chandra X-ray Observatory found evidence that the Milky Way Galaxy is embedded in a halo of hot gas that extends for hundreds of thousands of light years. Scientists estimated that the mass of the halo found is comparable to the mass of all the stars in...

Artificial Intelligence Maps The Universe
2012-09-24 11:48:59

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have developed an algorithm that is able to chart and explain accurately the structure and dynamics of the universe. The team developed a new algorithm based on artificial intelligence which provides results that are close to the observed distribution of motion and galaxies. It has been hard for astronomers to explain the distribution of galaxies. Five percent of the universe is made of normal matter, making up 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.

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...
