John P. Millis, Ph.D. for redOrbit.com - Your Universe Online In the normal course of evolution, galaxies initially formed stars as clouds of hydrogen and helium collapsed. Eventually the density and temperature of the cores would ignite nuclear fusion, allowing them to shine during what we call the main sequence phase of their lives. Eventually, stars will fuse heavier and heavier elements, with stars like our sun eventually culminating as balls of carbon and oxygen – in varying...

WASHINGTON, May 1, 2014 /PRNewswire-USNewswire/ -- Distant exploding stars observed by NASA's Hubble Space Telescope are providing astronomers with a powerful tool to determine the strength of naturally-occurring "cosmic lenses" that are used to magnify objects in the remote universe. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Two teams of astronomers, working independently, observed three such exploding stars, called supernovae. Their light was amplified by the immense...

Gamma-ray Burst
2014-05-01 04:41:32

redOrbit Staff & Wire Reports - Your Universe Online An international team of astronomers has for the first time measured circular polarization in the afterglow of gamma-ray bursts, the powerful flashes of radiation originating from massive dying stars as they collapse into black holes. A massive star explodes as a supernova when it dies, and its core collapses into a black hole, scientists from the Niels Bohr Institute explained in a statement Wednesday. In rare instances, a jet is...

Artist’s impression of the planet Beta Pictoris b
2014-04-30 12:55:00

European Southern Observatory VLT measures the spin of Beta Pictoris b Observations from ESO’s Very Large Telescope (VLT) have, for the first time, determined the rotation rate of an exoplanet. Beta Pictoris b has been found to have a day that lasts only eight hours. This is much quicker than any planet in the Solar System — its equator is moving at almost 100,000 kilometers per hour. This new result extends the relation between mass and rotation seen in the Solar System to...

elliptical galaxy M87
2014-04-30 12:25:17

Harvard-Smithsonian Center for Astrophysics The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher. It has thrown an entire star cluster toward us at more than two million miles per hour. The newly discovered cluster, which astronomers named HVGC-1, is now on a fast journey to nowhere. Its fate: to drift through the void between the galaxies for all time. "Astronomers have found runaway stars before, but this is the first time we've found a runaway star...

Caltech's Cosmic Web Imager Directly Observes "Dim Matter"
2014-04-30 03:53:16

Cynthia Eller, California Institute of Technology Caltech astronomers have taken unprecedented images of the intergalactic medium (IGM)—the diffuse gas that connects galaxies throughout the universe—with the Cosmic Web Imager, an instrument designed and built at Caltech. Until now, the structure of the IGM has mostly been a matter for theoretical speculation. However, with observations from the Cosmic Web Imager, deployed on the Hale 200-inch telescope at Palomar Observatory,...

Search For Life On Exoplanets May Be More Difficult Than Previously Thought
2014-04-30 03:25:19

Don Campbell, University of Toronto Scarborough A new study from the University of Toronto Scarborough suggests the search for life on planets outside our solar system may be more difficult than previously thought. The study, authored by a team of international researchers led by UTSC Assistant Professor Hanno Rein from the Department of Physical and Environmental Science, finds the method used to detect biosignatures on such planets, known as exoplanets, can produce a false positive...

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

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.

This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...

Tropic of Capricorn
2013-02-21 13:31:57

The Tropic of Capricorn, alternately called the Southern Tropic, is a marker of the most southerly latitude on the Earth at which the Sun can be directly overhead. This occurs at the December solstice, when the southern hemisphere is tilted towards the sun at its maximum degree. It is one of the five major circles of latitude that mark maps of the Earth. It presently lies 23 degrees 26’ 16’’ south of the Equator. Currently, the Tropic of Capricorn is drifting towards the north at...
