With special filtered telescopes you can observe the sun safely without hurting your eyes.There's more to the sun than just a yellow ball. See for yourself what the sun's surface and atmosphere look like--93 million miles away.
Our educators can provide a Solar Astronomy Outreach for your community organization, classroom, school, homeschool association or scout troop. View our brochure for more details.

11/17/17: Solar Minimum Surprisingly Constant - More than Half a Century of Observation yields New Discovery. Using more than half a century of observations, Japanese astronomers have discovered that the microwaves coming from the Sun at the minimums of the past five solar cycles have been the same each time, despite large differences in the maximums of the cycles.

11/14/17: Proposed NASA Mission Would Investigate Where Space Weather Begins. A NASA team is advancing a mission to reveal unprecedented details about solar flares, powerful eruptions that explode with enough energy that each one could power all of Earth for 16,000 years, and which — when extreme — can interfere with radio communications and satellites near Earth.[Solar Observation]
11/07/17: Alma’s image of red giant star gives a surprising glimpse of the Sun’s future. A Chalmers-led team of astronomers has for the first time observed details on the surface of an aging star with the same mass as the Sun. ALMA:s (Atacama Large Millimetre/Submillimetre Array) images show that the star is a giant, its diameter twice the size of Earth’s orbit around the Sun, but also that the star’s atmosphere is affected by powerful, unexpected shock waves.
8/14/17: Cosmic Opportunity for Readiation Research at ESA. Cosmic radiation is considered the main health hazard to human spaceflight and space exploration of the Moon, Mars and beyond, which is why ESA has made cosmic radiation a focus of its research programme. [Health Effects]
6/27/17: Solar Minimum is Coming. Every 11 years or so, sunspots fade away, bringing a period of relative calm, known asthe Solar Minimum. [NASA Sciencecast] [Solar Cycles]
6/22/17: Scientists Uncover Origins of the Sun’s Swirling Spicules. At any given moment, as many as 10 million wild jets of solar material burst from the sun’s surface. They erupt as fast as 60 miles per second, and can reach lengths of 6,000 miles before collapsing. These are spicules, and despite their grass-like abundance, scientists didn’t understand how they form. Now, for the first time, a computer simulation — so detailed it took a full year to run — shows how spicules form, helping scientists understand how spicules can break free of the sun’s surface and surge upward so quickly.

5/8/17: Space Weather Model Simulates Solar Storms From Nowhere. An international team of scientists has developed a model that simulates the evolution of stealthy solar storms. The scientists relied upon NASA missions STEREO and SOHO for this work, fine-tuning their model until the simulations matched the space-based observations. Their work shows how a slow, quiet process can unexpectedly create a twisted mass of magnetic fields on the sun, which then pinches off and speeds out into space — all without any advance warning.

5/5/17: NASA-Funded Sounding Rocket Will Take 1,500 Images of Sun in 5 Minutes. On May 5, 2017, scientists launched a sounding rocket 200 miles up into the atmosphere, where in just five minutes, it will take 1,500 images of the sun. The NASA-funded RAISE mission is designed to scrutinize split-second changes occurring near the sun’s active regions — areas of intense, complex magnetic activity that can give rise to solar flares, which eject energy and solar material out into space.
4/24/17: NASA’s Cassini, Voyager Missions Suggest New Picture of Sun’s Interaction with Galaxy. New data from NASA’s Cassini mission, combined with measurements from the two Voyager spacecraft and NASA’s Interstellar Boundary Explorer, or IBEX, suggests that our sun and planets are surrounded by a giant, rounded system of magnetic field from the sun — calling into question the alternate view of the solar magnetic fields trailing behind the sun in the shape of a long comet tail.

4/19/17: Living with a Star: NASA and Partners Survey Space Weather Science. Last year, NASA scientists worked with scientists and engineers from research institutions and industry during a pair of intensive week-long workshops in order to assess the state of science surrounding this type of space weather. [Space Weather]
4/10/17: Solar Storms Can Drain Electrical Charge Above Earth. New research on solar storms finds that they not only can cause regions of excessive electrical charge in the upper atmosphere above Earth's poles, they also can do the exact opposite: cause regions that are nearly depleted of electrically charged particles. The finding adds to our knowledge of how solar storms affect Earth and could possibly lead to improved radio communication and navigation systems for the Arctic.
3/31/17: PPPL and Max Planck physicists reveal experimental verification of a key source of fast reconnection of magnetic fields. Magnetic reconnection, a universal process that triggers solar flares and northern lights and can disrupt cell phone service and fusion experiments, occurs much faster than theory says that it should. Now researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Germany’s Max Planck Institute of Plasma Physics have discovered a source of the speed-up in a common form of reconnection. Their findings could lead to more accurate predictions of damaging space weather and improved fusion experiments.
3/30/17: Rossby waves, large movement patterns in the atmosphere, have been found on the sun, and their discovery could help make better long-term space weather predictions.

Parker Solar Probe to launch summer of 2018
Parker Solar Probe. As NASA’s Parker Solar Probe spacecraft begins its first historic encounter with the sun’s corona in late 2018—flying closer to our star than any other mission in history—a revolutionary cooling system will keep its solar arrays at peak performance, even in extremely hostile conditions.
