Image description: At the end of August, a filament from the sun suddenly erupted into space. The filament had been held up for days by the Sun’s ever changing magnetic field and the timing of the eruption was unexpected. Learn more about the eruption.

Image description: Should you put sunscreen on infants? Not usually. The best approach is to keep infants under 6 months out of the sun, especially between 10:00 AM and 2:00 PM.
But when you are outside together, here are some of the most important ways to protect your infant from the harmful rays of the sun: an umbrella and brimmed hat for shade, a cooler for liquids, a bottle for hydration, and clothing for covering the skin.

Image description: These images show a solar flare as observed on January 23. You can see the sun’s surface brighten as gas was superheated and magnetically supercharged. In the far right image, there is a stream of solar material flowing into space, likely solar protons and a coronal mass ejection.
Solar flares and coronal mass ejections are not a danger to humans on Earth. The planet’s magnetic field and atmosphere deflect and absorb the energy. Sun storms can pose some risks to astronauts, and upset science, military, and communications satellites.

Image description: This photograph of the corona of the sun was taken during a solar eclipse in 1900 by Smithsonian photographer Thomas Smillie. A team from the Smithsonian Astrophysical Observatory loaded several railroad cars with scientific equipment and headed to Wadesboro, North Carolina. Scientists had determined that this small town would be the best location in North America for viewing an expected total solar eclipse, and the expedition hoped to capture photographic proof of the sun’s corona. Smillie rigged cameras to seven telescopes and successfully made eight glass-plate negatives. At the time, Smillie’s work was considered an amazing photographic and scientific achievement.
