Latest Sun Stories
Scientists have now spotted at planet Mercury, for the first time, a classic space weather event called a hot flow anomaly, or HFA, which has previously been spotted at Earth, Venus, Saturn and Mars.
Dating the formation of the Earth is a difficult process, because usually geological dating methods do not work as well.
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 1.6 meter telescope at Big Bear Solar Observatory (BBSO) in California has given researchers unparalleled capability for investigating phenomena such as solar flares.
OTTAWA, June 3, 2014 /CNW/ - The Canadian Dermatology Association (CDA) is challenging young people across Canada to put their creativity to work and make a short video about sun safety as part
A coronal mass ejection, or CME, surged off the side of the sun on May 9, 2014, and NASA's newest solar observatory caught it in extraordinary detail.
How do solar systems form? Specifically, why do some systems form smaller rocky worlds, while others are dominated by gas giants? A recent study led by Trey Mack, a graduate student in astronomy at Vanderbilt University, may have found the answer.
Previous research has found that the electrical bolts are caused by cosmic radiation and a new study has found that streams of high-energy particles from the Sun accelerated by the solar wind also play a role.
This article is the latest installment in a new series where redOrbit's in-house experts will answer questions submitted by you, the reader. This week's question: "Why does earth rotate?" Our resident expert explains.
A team of astronomers have identified what is believed to be the sibling of our sun – a star thought to have been born from the same cloud of gas at the one that provides our solar system with light and warmth.
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...
