The Solar Dynamics Orbiting Observatory continuously monitors the sun in 10 wavebands, mostly in the extreme ultraviolet part of the spectrum. These UV emissions correspond to super-heated gas in the million-degree range. Our full-featured video is linked below. When observing the sun in visible light, it seems benign enough and is something we’re used to[…]
The sun as recorded in the extreme ultraviolet part of the spectrum by NASA’s Solar Dynamics Observatory (SDO) between July 6 and July 10. Pay particular attention to the bright orange-pink outburst that occurs on July 8 at the 10:00 position on the solar disk. This was a magnitude 2.6 M-Class flare, a classification one[…]
Video link below We were reminded of the enormous power of our home star on November 29 of last year (2020), when NASA’s Solar Dynamics Observatory recorded a powerful Solar Flare, entitled the ‘Anemone’ Eruption’! In this video, Dr. James Daly presents and discusses our sun and the spectacular display witnessed on November 29, 2020.[…]

How does the sun and other stars shine? In this, the first of a multi-part series, Dr. James Daly of Astronomy For Change (https://astronomyforchange.org) teaches us and illustrates how stars, incredibly dynamic and self-regulating, shine and evolve. With this video, we start with the sun as a model and an up-close and personal laboratory to[…]
The cover image for the feature video (also above) was produced from Dr. Daly’s composite image of the totally eclipsed sun as observed during his eclipse expedition to Cabo San Lucas, Mexico, 11 July 1991. We hosted a live event via YouTube today, 2 July, 2019 presenting the Great Latin American Eclipse of 2019. Decribing[…]
This Tuesday, July 2nd, observers in Chile, Argentina and Uruguay will be witness to one of nature’s most awesome spectacles, a Total Eclipse of the Sun. A total eclipse of the sun occurs when the moon, at “New” Phase, perfectly covers the disk of the sun. Since the moon is 400x smaller than the sun,[…]
Every year on the 29th of May, the anniversary of the famous 1919 Total Solar Eclipse, we celebrate Einstein’s Triumph, the experiment that provided incontrovertible evidence for the veracity of his theory on Gravity, the General Theory of Relativity. Up until the turn of the 20th century, the natural universe was governed by Newton’s Laws;[…]
As the last vestiges of the winter sky are low in the west at twilight, we look forward to the late spring and early summer sky. With Lyra the celestial harp ascending the northeastern sky towards midnight along with Cygnus and the rich summer Milky Way following close behind, we’re certain that spring is here[…]
Composite video of the sun as imaged by the Solar Dynamics Observatory in three false-color, high-energy wavebands between 5 September and 7 September of this year showing the magnitude 9.3 X-class solar flare as a bright pink outburst. Link to original HD video available here and on our YouTube channel here. What would happen if[…]
Reposted from The Class Dismissed Podcast, Inspiring Educators Through Story Original article Published by Ortego Communications Astronomer Glenn Schneider has been chasing total eclipses since he was 14 years old. In all, he’s witnessed 33, an accomplishment that only two other people in history can put on their resume. Credit: Dr. Glenn Schneider August 21, Schneider will[…]
Update to this topic: The Ten Brightest Stars (and where they are, with video) – 1. Arcturus Going out to look up at the stars on a clear, dark night can be daunting, if not for its beauty and majesty but for what may seem like an uncountable number of stars; you often hear the[…]
Note: Following observations of the 2 August Transit of the moon across the sun, SDO failed to return to Science mode, hence the blank video composites below. Daily, Dynamic Video Composite Loops of the Sun in the light of Extreme UltraViolet and soft X-Rays High-Definition Movies of the Raging Sun 24/7 Be the first to[…]
A relatively strong, C-class solar flare was observed on Sunday, July 17th by NASA’s Solar Dynamics Observatory. The flare is noteworthy in that the sun has been relatively quiescent, on its way to solar minimum. The image and the accompanying video below are composites, compiled from hard Ultraviolet and X-ray images obtained by the SDO,[…]
