Karen C. Fox, NASA's Goddard Space Flight Center Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun's outer atmosphere so much hotter than its surface. The new observations of the small-scale extremely hot temperatures are consistent with only one current theory: something called nanoflares – a constant peppering of impulsive bursts of heating, none of which can be individually detected -- provide the mysterious extra heat. [ Watch:...

April Flowers for redOrbit.com - Your Universe Online University of Bristol’s professor of Aerospace Engineering Ashley Dale cautions that “solar super-storms” are going to cause “catastrophic” and “long-lasting” impacts if we continue to ignore the threat of such storms. Dale is a member of the international task force SolarMAX, which was designed to identify the risks of a solar storm and how humanity could minimize the risks. He believes that a particularly violent...

farthest cosmic lens

redOrbit Staff & Wire Reports - Your Universe Online A massive new elliptical galaxy unexpectedly discovered using NASA’s Hubble Space Telescope is the most distant lensing galaxy ever discovered, officials from the US space agency confirmed in a statement Thursday. Lensing galaxies essentially act as a cosmic magnifying glass, and are large enough that their gravity can bend and distort light in such a way that they can make it easier to detect more distant objects in space....

Lifetime Of Gravity Measurements Brings New Beginning
2014-08-01 03:08:45

ESA Although ESA’s GOCE satellite is no more, all of the measurements it gathered during its life skirting the fringes our atmosphere, including the very last as it drifted slowly back to Earth, have been drawn together to offer new opportunities for science. Carrying the first 3D gravity sensor in space, this state-of-the-art satellite measured Earth’s gravity with unprecedented accuracy. GOCE’s four years in orbit resulted in a series of four gravity models, each more...

redOrbit Staff & Wire Reports - Your Universe Online More than four decades after US astronauts first visited the lunar surface, scientists have finally determined both the actual shape of the moon and the forces responsible for giving it that form, according to a new study published this week in the journal Nature. As it turns out, the moon is somewhat flattened with a bulge on one side, the authors told Douglas Quenqua of the New York Times. University of California, Santa Cruz...

Nuclear Fallout
2013-04-01 10:26:30

Nuclear fallout, or just simply fallout, known also as Black Rain, is the residual radioactive material that is propelled into the upper atmosphere after a nuclear black or a nuclear reaction that is conducted in an unshielded facility. It is so called because it "fall out" of the sky after the explosion and the shock wave have passed. It most commonly refers to the radioactive dust and ash that is created when a nuclear weapon explodes, but such dust can also come from a damaged nuclear...

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.

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...

Basic Ocean Terms
2013-02-05 12:52:11

Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...

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...

  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
