April Flowers for redOrbit.com - Your Universe Online On July 14, NASA will launch a sounding rocket from White Sands Missile Range in New Mexico. A little before noon, the rocket will streak 180 miles into the atmosphere, sending it into the thermosphere layer, beyond the ozone's ability to block the sun's high energy light. Sounding rockets are small payload, scientific research rockets. Named for the nautical term "to sound," which means to take measurements, the rockets have been...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The holy grail of planetary astronomy is to find a solar system that mirrors our own. While a lot of effort has been placed on finding a planet with Earth-like properties – the right size, an atmosphere, the right temperature – are of equal importance in the search for a Sun-like star. Such a glowing orb would need to have a similar mass, temperature, and spectral type. These parameters are somewhat easy to measure, but...

far side solar flare
2014-07-10 07:19:47

redOrbit Staff & Wire Reports - Your Universe Online In order to better understand what powers solar flares, NASA officials announced on Thursday that they were turning to the MESSENGER spacecraft orbiting Mercury in order to get a closer look at these intense bursts of radiation resulting from sunspot-related magnetic energy release. As the US space agency explained, it can be difficult understanding some of the processes on the sun when you are forced to rely solely upon the...

summer flare
2014-07-09 04:00:48

Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a mid-level solar flare, peaking at 12:20 p.m. EDT on July 8, 2014, and NASA's Solar Dynamics Observatory captured images of the event. 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...

SETI Institute A team of researchers in the U.S. and Germany has measured the highest level of ultraviolet radiation ever recorded on the Earth's surface. The extraordinary UV fluxes, observed in the Bolivian Andes only 1,500 miles from the equator, are far above those normally considered to be harmful to both terrestrial and aquatic life. The results are being published in the open-access journal Frontiers in Environmental Science. "These record-setting levels were not measured in...

Voyager 1 Entering Interstellar Space
2014-07-08 03:45:14

redOrbit Staff & Wire Reports - Your Universe Online A new “tsunami wave” generated by the sun has helped NASA scientists confirm that Voyager 1 is currently traveling through interstellar space, or the area between the stars that is filled with charged particles known as plasma, the US space agency reported on Monday. Waves like these are what initially led astronomers to conclude that the spacecraft had escaped the magnetic bubble surrounding the sun and planets known as the...

NASA's STEREO Mission Being Prepped For Upcoming Orbital Phase
2014-07-04 10:27:41

[ Watch the Video: STEREO Solar Conjunction ] Gerard LeBlond for redOrbit.com - Your Universe Online NASA’s STEREO mission began in 2006 and has been providing scientists with images from the far side of the sun since February 2011. The spacecraft duo that were placed in orbit around the sun are now about to embark on the next phase of their mission. The two STEREO (Solar Transfer Relations Observatory) probes orbit the sun at different speeds and different locations. “Both...

IRIS Solar Observatory After 1 Year In Space

[ Watch The Video: A First For IRIS: Observing A Gigantic Solar Eruption ] Karen C. Fox, NASA On June 27, 2013, NASA's newest solar observatory was launched into orbit around Earth. The Interface Region Imaging Spectrograph, or IRIS, observes the low level of the sun's atmosphere -- a constantly moving area called the interface region -- in better detail than has ever been done before. During its first year in space, IRIS provided detailed images of this area, finding even more...

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

Royal Astronomical Society 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. And the thousands of droplets that make up a 'coronal rain' shower are themselves each as big as Ireland. Now a team of solar...

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...

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...

Being a meteorologist for over thirteen years you start to take note of many things in the atmosphere and how they repeat themselves. Our Climate is no different. The definition of climate is stated as: the collective weather data in regards to moisture and temperature for over 30 years for the same location. So to better understand our climate we need to look at this. First, we have average temperatures for given places based on the 30 year average. Some years the temps are warmer or...

Solar Physics is a journal for solar and solar-stellar research and the study of solar terrestrial physics. Founded in 1967 by solar physicist Cornelis de Jager and publisher D. Reidel, the journal treats all aspects of solar physics, ranging from the internal structure of the Sun and its evolution, to outer corona and solar wind in interplanetary space. Solar Physics has four more than forty years been the principal journal for publications of fundamental research on the Sun. It is...

The spectroheliograph captures a photographic image of the Sun at a single wavelength of light. The wavelength chosen usually coincides with a spectral wavelength of one of the chemical elements present in the Sun. George Ellery Hale and Henri-Alexadre Deslandres developed I independently in 1890 and was further refined in 1932 by Robert R. McMath to take motion pictures. It operates by using a prism together with a narrow slit that passes a single wavelength. The light focuses on a...
