Latest Solar cycle Stories
The RHESSI (Ramaty High Energy Solar Spectroscopic Imager) satellite focuses on the highest energy x-rays and gamma-rays produced by the sun, helping to observe solar flares of all shapes and sizes.
New research shows that other sun-like stars in the universe can send off flares much larger than those seen on our sun.
Researchers are investigating a link between the massive solar minimum that occurred around 2800 years ago and the effects that it had on the climate of Europe.
Approximately every 11 years the magnetic field on the sun reverses completely – the north magnetic pole switches to south, and vice versa.
What is actually happening on Earth? Here are some things that you need to understand before we go on. First are terms such as Solar Cycle, Solar Maximum, and Solar Minimum. By understanding these terms, the rest will make more sense.
Hydrogen molecules may act as a kind of energy sink that strengthens the magnetic grip that causes sunspots, according to scientists from Hawaii and New Mexico using a new infrared instrument on an old telescope.
According to a study published Monday, the slightly weaker activity of the sun expected in the coming 90 years will not be enough to significantly curb rising global temperatures.
Given a legitimate need to protect Earth from the most intense forms of space weather – great bursts of electromagnetic energy and particles that can sometimes stream from the sun – some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth.
NASA's Solar Dynamics Observatory (SDO) spotted one of the largest new sunspots to have appeared on the surface of the sun in years.
One hundred and fifty two years ago, a man in England named Richard Carrington discovered solar flares.
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...
Solar Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...
