What are Solar Glasses Made of and How Do They Work
By Eric Gentry Solar glasses typically need to meet two constraints: You need something which will block most of the light, and you need something that can provide structural support, so it won’t fall apart while you’re staring at the sun. Thanks to modern chemistry, most of the ‘solar eclipse […]
Time-Lapse Of the Sun and Sunspots
The NOAA hasan amazing video showing the time-lapse off the Sun and sunspots starting from the beginning of Solar Cycle 25. As the NOAA team notes in a recent article, “In case you missed it, Solar Cycle 25 has ramped up much faster than scientists predicted producing more sunspots and eruptions […]
