Sunspots Moving Across The Sun
2013-11-14 14:28:37

[ Watch The Video: Sputtering Spot – The Last Days of AR11890 ] NASA Two large, complex sunspots are moving across the face of the sun. One, which produced considerable solar activity in the past weeks, has almost rotated off completely. A new sunspot rounded into view on Nov. 11, 2013 and is now making its way across the Earth-side of the sun. An active region can contain one or more sunspots. The National Oceanic and Atmospheric Administration numbers active regions consecutively as...

Spectacular Stellar Landscape Painted With Young Stars
2013-11-13 13:50:28

[ Watch The Video: Zooming in on the Star Cluster NGC 3572 ] ESO Astronomers at ESO have captured the best image so far of the curious clouds around the star cluster NGC 3572. This new image shows how these clouds of gas and dust have been sculpted into whimsical bubbles, arcs and the odd features known as elephant trunks by the stellar winds flowing from this gathering of hot young stars. The brightest of these cluster stars are much heavier than the Sun and will end their short...

Sun Emits Seventh Significant Flare Since Oct. 23, 2013
2013-11-11 07:51:25

NASA The sun emitted a significant solar flare that peaked at 1:14 a.m. EST on Nov. 10, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. To see how this event may impact Earth, please visit NOAA's Space Weather Prediction Center at...

Revealing New Information On Strength Of Black Hole Mergers
2013-11-08 07:13:10

Lee Rannals for redOrbit.com - Your Universe Online The Commonwealth Scientific and Industrial Research Organization (CSIRO) in eastern Australia has helped reveal new information about the strength of black hole mergers. Giant black holes throughout the universe sometimes pair up and merge, sending out gravitational waves that ripple across space and time. Albert Einstein predicted that these waves exist, but scientists have yet to directly detect one. Astronomers were able to...

Astronomers Say Supernova Will Be Visible From Earth Within 50 Years
2013-10-31 16:04:47

[ Watch the Video: Is There A Supernova In Your Future? ] Brett Smith for redOrbit.com - Your Universe Online A supernova is one of the most brilliant events to take place in the universe and astronomers at The Ohio State University have determined we will see one in the Milky Way Galaxy within the next 50 years. While the odds of actually seeing a star explode with the naked eye is very low during that time span, a supernova would be visible to specialized telescopes in the form of...

VANCOUVER, Oct. 31, 2013 /PRNewswire/ - Sierra Metals Inc. (TSX:SMT)(BVL:SMT) ("Sierra Metals" or the "Company") announces the filing of Sociedad Minera Corona S.A.'s ("Corona") unaudited Financial Statements and Management Discussion and Analysis ("MD&A") for the third quarter of 2013. The Company holds an interest of 81.8% in Corona. All amounts are presented in thousands of US dollars unless otherwise stated and have not been adjusted for the 18.2% non-controlling interest....

Violent Youth Seeded The Universe With Iron
2013-10-31 05:07:20

April Flowers for redOrbit.com - Your Universe Online The universe underwent a turbulent and violent youth more than 10 billion years ago, as evidenced by iron spread evenly between galaxies in one of the largest galaxy clusters in the Universe. This violent youth was responsible for seeding the cosmos with iron and other heavy elements that are critical to life itself, according to the new study published in Nature. Scientists from the Kavli Institute for Particle Astrophysics and...

Sun Produces Fourth X-class Flare In A Week
2013-10-30 11:04:01

NASA The sun emitted a significant solar flare – its fourth X-class flare since Oct. 23, 2013 -- peaking at 5:54 p.m. on Oct. 29, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This disrupts the radio signals for as long as the flare is ongoing,...

Third Solar Flare Emitted By The Sun In Two Days
2013-10-25 12:12:19

NASA [ Watch The Video: Experimental NASA Research Model of Path for Oct. 22-23 CMEs ] The M9.4 flare on Oct. 23, 2013, was associated with a coronal mass ejection or CME, a solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. Another solar flare erupted from the same area...

Coldest Known Object In Space Reveals Its Ghostly Figure
2013-10-25 06:25:12

April Flowers for redOrbit.com - Your Universe Online The Boomerang Nebula, at a crisp one degree Kelvin (-458 degrees Fahrenheit), is the coldest known object in the Universe. In fact, the Boomerang Nebula is colder than the faint afterglow of the Big Bang, which is the natural background temperature of space. To learn more about this intriguing object, a team of astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) telescope to investigate its frigid properties and...

Stellar Astrophysics

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: NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light-years in diameter and approximately 60 million light-years distant. Credit: NASA/ESA/Wikipedia What is Astrophysics? For much of the modern age the term Astrophysics has been used synonymously with Astronomy. 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...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...

Physics
2014-01-12 00:00:00

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Astronomy and Astrophysics Review
2012-04-25 09:55:47

The Astronomy and Astrophysics Review is a peer-reviewed scientific journal published quarterly by Springer Science Business Media. The editor-in-chief is Thierry Courvoisier. It was first published in April 1989. The journal covers all areas of astronomy and astrophysics, including cosmic ray physics, studies in the solar system, astrobiology, developments in laboratory or particle physics relevant to astronomy, instrumentation, computational or statistical methods with specific...
