Latest Sun Stories
LONDON, July 28, 2014 /PRNewswire/ -- Reportbuyer.com has added a new market research report:
Two years ago today, Earth experienced a close shave just as perilous as an asteroid, but most newspapers didn't mention it. The "impactor" was an extreme solar storm, the most powerful in as much as 150+ years.

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.
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 – of equal importance is the search for a Sun-like star.
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.
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.
Researchers have measured the highest levels of ultraviolet radiation ever recorded on the Earth's surface in the Bolivian Andes only 1,500 miles from the equator that are far above those normally considered to be harmful to both terrestrial and aquatic life.
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.
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 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...
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...
