European Space Agency Selects Athena Advanced Telescope For Study Of High-Energy Astrophysics
2014-06-27 09:41:59

The European Space Agency (ESA) is in the process of launching a second “Large-class” mission to explore the universe for high-energy astrophysics and selected the Athena advanced telescope for the task.

Sun Has Bad Weather Just Like On Earth
2014-06-26 03:31:08

Just like on Earth, the Sun has spells of bad weather, with high winds and showers of rain. But unlike the all-too-frequent storms of the UK and Ireland, rain on the Sun is made of electrically charged gas (plasma) and falls at around 200,000 kilometers an hour from the outer solar atmosphere, the corona, to the Sun's surface.

Astronomers Use AKARI Orbiting Observatory To Map Space’s Icy Wastes
2014-06-26 03:40:16

Using the AKARI orbiting observatory, astronomers from the Open University have made the first large-scale maps of icy material where stars are forming.

Dark Energy Survey Discovers Exotic Supernova
2014-06-26 03:28:35

The first images taken by the Dark Energy Survey (DES) after the survey began in August 2013 have revealed a rare, ‘superluminous’ supernova that erupted in a galaxy 7.8 billion light years away.

Astronomers using NASA’s Solar Terrestrial Relations Observatory (STEREO) have discovered that the atmosphere of solar particles surrounding the sun is larger than previously believed, extending out some five million miles above the surface.

Star Measurement Made Easier With A Novel Spectral Ruler
2014-06-23 14:32:00

Being hailed as a critical first step in a massive attempt to map the Milky Way, a team of European astronomers has devised a novel way to categorize stars based on their metallic composition

A suite of Sun-gazing spacecraft, SOHO, STEREO and Solar Dynamics Observatory (SDO), have spotted an unusual series of eruptions in which a series of fast 'puffs' force the slow ejection of a massive burst of plasma from the Sun's corona.

Earth's Magnetosphere Doesn't Stop All Solar Wind From Breaking Through
2014-06-11 14:41:29

Using data from four European Space Agency satellites that fly in formation in the Earth's magnetic field, researchers have uncovered new information on how the solar wind can break through the Earth’s magnetosphere and disrupt modern life.

3 x-class flares
2014-06-11 08:40:19

The sun emitted a significant solar flare, peaking at 7:42 a.m. EDT on June 10, 2014. NASA's Solar Dynamics Observatory (SDO) – which typically observes the entire sun 24 hours a day -- captured images of the flare.

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...

bretelles
  • In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
The word 'bretelles' comes from a French word meaning 'braces'.
