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...

Heavy Metal Stars
2013-08-01 14:00:20

Lee Rannals for redOrbit.com - Your Universe Online Astronomers from the Armagh Observatory in Northern Ireland say they have discovered two unusual, heavy metal stars. The team wrote in the journal Monthly Notices of the Royal Astronomical Society that they found the stars HE 2359-2844 and HE 1256-2738 to contain extremely high concentrations of lead in their atmospheres. Naslim Neelamkodan, Simon Jeffery, Natalie Behara and Alan Hibbert said these two stars have surfaces containing...

New Tool Uses Radio Waves To Predict Climate Change
2013-07-31 11:15:23

Lee Rannals for redOrbit.com - Your Universe Online Tel Aviv University (TAU) scientists developed a new tool to measure climate change by using radio waves. The ionosphere is a region in the upper atmosphere that plays a vital role for global communications. This region is used for the transmission of long wave communications, such as radio waves, and now scientists have found waves from the ionosphere offer valuable news about climate change. The team wrote in the Journal of...

Unraveling Galactic History Begins With A Black Hole's Spin
2013-07-30 14:11:38

Brett Smith for redOrbit.com - Your Universe Online A supermassive black hole is believed to sit at the center of each large galaxy, and a new technique designed to detect the dark abyss' spin could be the key to unraveling a galaxy's history. While black holes cannot be seen directly, their behavior can be determined by looking at how they affect nearby objects. A paper published in Monthly Notices of the Royal Astronomical Society describes a new technique that was developed by...

IRIS offers first images of sun atmosphere
2013-07-25 15:10:18

Lee Rannals for redOrbit.com - Your Universe Online NASA's Interface Region Imaging Spectrograph (IRIS) has provided scientists with their first look at the Sun's atmosphere. On July 17, an international team of scientists and engineers working on IRIS saw their hard work pay off when the telescope provided its first glimpse, showing unprecedented detail of a little-observed region of the sun. "These beautiful images from IRIS are going to help us understand how the sun's lower...

Quasar Radiation Influences Galaxy Growth
2013-07-25 05:58:07

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists writing in The Astrophysical Journal have shed some new light on the universe's brightest objects - quasars. The team from Dartmouth University published details about discoveries based on 10 quasar observations. They wrote about the power of quasar radiation, which can reach out for many thousands of light years to the limits of the quasar's galaxy. Astrophysicists Ryan Hickox and Kevin Hainline and colleagues used...

SUNNYVALE, Calif., July 23, 2013 /PRNewswire/ -- Cepheid (Nasdaq: CPHD) and the American Lung Association (www.Lung.org) today announced a partnership to promote tuberculosis-related awareness in the U.S. and the need for improved TB (tuberculosis) diagnostics. Details of the planned program will be announced at the American Association of Clinical Chemistry and Clinical Lab Expo show in Houston, Texas. The live announcement will take place at 10am on July 30(th) at Cepheid...

“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...

Scientists Study Magnetic Reconnection Effects On Space Weather
2013-07-16 16:03:08

Brett Smith for redOrbit.com - Your Universe Online Using observations from two different NASA spacecraft, scientists have shed new light on the process behind solar flares and eruptions: magnetic reconnection. Magnetic reconnection occurs when magnetic lines collide and break apart - snapping into new positions and releasing energy in the process. On the sun, magnetic reconnections can result in radiation and solar material being flung across the solar system. These reconnections also...

Stellar Astrophysics
2014-01-12 00:00:00

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...
