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.

Reversing Prominence. A prominence rose up above the sun, sent an arch of plasma to link up magnetically with an active region over a one-day period (Jan, 9-10, 2017). Then the flow of plasma seemed to largely change direction and head back where it came from. Finally, amidst the confused patterns of movement, it dissipated and fell away. Prominences are cooler clouds of charged particles tenuously tethered to the sun by magnetic forces. Images were taken in a wavelength of extreme ultraviolet light.

03/06/18: 70-year-old mystery of how magnetic waves heat the Sun cracked. Scientists at Queen's University Belfast have led an international team to the ground-breaking discovery that magnetic waves crashing through the Sun may be key to heating its atmosphere and propelling the solar wind.

03/01/18: Sounding Rocket Mission Will Trace Auroral Winds. Understanding the contribution that aurora make to the total amount of energy that enters and leaves Earth’s geospace system — referred to as auroral forcing — is one of the major goals of the NASA-funded Auroral Zone Upwelling Rocket Experiment, or AZURE. AZURE is the first of eight sounding rocket missions launching over the next two years as part of an international collaboration of scientists known as The Grand Challenge Initiative – Cusp.

02/26/18: Proxima Centauri's no good, very bad day. A team of astronomers led by Carnegie’s Meredith MacGregor and Alycia Weinberger detected a massive stellar flare—an energetic explosion of radiation—from the closest star to our own Sun, Proxima Centauri, which occurred last March. This finding raises questions about the habitability of our Solar System’s nearest exoplanetary neighbor, Proxima b, which orbits Proxima Centauri.
02/14/18: Scientists directly observe electron dynamics of the Northern Lights. The shower of electrons bouncing across Earth's magnetosphere -- commonly known as the Northern Lights -- has been directly observed for the first time by an international team of scientists. While the cause of these colorful auroras has long been hypothesized, researchers had never directly observed the underlying mechanism until now. [Auroras]
02/09/18: Astrophysicists settle century-old cosmic debate on magnetism of planets and stars. Using one of the world's most powerful laser facilities, a team of scientists experimentally confirmed a long-held theory for cosmic magnetic field generation: the turbulent dynamo. By creating a hot turbulent plasma the size of a penny, that lasts a few billionths of a second, the researchers recorded how the turbulent motions can amplify a weak magnetic field to the strengths of those observed in our sun, distant stars, and galaxies.

02/08/18: Towards a better prediction of solar eruptions. Just one phenomenon may underlie all solar eruptions. Researchers have identified the presence of a confining 'cage' in which a magnetic rope forms, causing solar eruptions. It is the resistance of this cage to the attack of the rope that determines the power and type of the upcoming flare. This work has enabled the scientists to develop a model capable of predicting the maximum energy that can be released during a solar flare. [Solar Flares]
01/30/18: Stellar magnetism: What's behind the most brilliant lights in the sky?. Space physicists at University of Wisconsin–Madison have just released unprecedented detail on a bizarre phenomenon that powers the northern lights, solar flares and coronal mass ejections (the biggest explosions in our solar system).The data on so-called “magnetic reconnection” came from a quartet of new spacecraft that measure radiation and magnetic fields in high Earth orbit. [Magnetic Fields]
01/17/18: Parker Solar Probe Enters Thermal Vacuum Chamber. Parker Solar Probe is slowly lifted and carried to the top of the thermal vacuum chamber, which will simulate the airless environment of space, in addition to conducting intense hot and cold temperature testing.Credit: NASA/JHUAPL/Ed Whitman.
12/11/17: Eclipse 2017: Science from the Moon’s Shadow. On Dec. 11, 2017, six researchers discussed initial findings based on observations of the Sun and on Earth gathered during the solar eclipse that stretched across North America on Aug. 21, 2017
11/28/17: TSIS: Total and Spectral Solar Irradiance Sensor. In terms of climate change research, scientists need to understand the balance between energy coming in from the Sun and energy radiating out from Earth. In December 2017, NASA is launching a new instrument to measure half of that equation – the total amount of Sun’s energy input to Earth, known as total solar irradiance. Scientists will use NASA's Total Solar and Spectral Irradiance Sensor (TSIS-1) to measure to quantify variations in the sun’s total amount of energy and help improve models simulating Earth’s climate. [Solar Observation]
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. [solar 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]

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.
