The Red Sprite and the Tree Credit & Copyright: Maxime Villaeys

Explanation: The sprite and tree could hardly be more different. To start, the red sprite is an unusual form of lightning, while the tree is a common plant. The sprite is far away – high in Earth’s atmosphere, while the tree is nearby – only about a football field away. The sprite is fast – electrons streaming up and down at near light’s speed, while the tree is slow – wood anchored to the ground. The sprite is bright – lighting up the sky, while the tree is dim – shining mostly by reflected light. The sprite was fleeting – lasting only a small fraction of a second, while the tree is durable – living now for many years. Both however, when captured together, appear oddly similar in this featured composite image captured early this month in France as a thunderstorm passed over mountains of the Atlantic Pyrenees.

The Gargoyles’ Eclipse Image Credit & Copyright: Bertrand Kulik

Explanation: In dramatic silhouette against a cloudy daytime sky over Paris, France, gargoyles cast their monstrous gaze outward from the west facade of Notre Dame Cathedral. Taken on March 29, this telephoto snapshot also captures the dramatic silhouette of a New Moon against the bright solar disk in a partial solar eclipse. Happening high in Parisian skies, the partial eclipse was close to its maximum phase of about 23 percent. Occurring near the end of the first eclipse season of 2025, this partial solar eclipse followed the total eclipse of the Full Moon on March 13/14. The upcoming second eclipse season of 2025 will see a total lunar eclipse on September 7/8 and partial solar eclipse on September 21. The partial solar eclipse will be seen only from locations in planet Earth’s southern hemisphere.

A personal item was found on the observatory decks the day after our public night. If you lost something, check with the Dean's office in the DMF Science and Math Center!

Wed. Oct. 22: We'll be open tonight from 7 - 8 pm. We expect some clouds, but we should still be able to catch some nice glimpses of the sky. Saturn is still the star of the show!

I think the moons in this image could be Titania, Umbriel, Ariel, and Oberon, tho which points of light they are is hard to say

Wed. 11/13: We expect gorgeous, clear skies tonight! We'll be open, 6 -7 for public night and from 7 - 9 for attendees of Open Lab Night.

Please be aware the elevator which goes to the 5th floor (observatory) is out of order. We will only be accessible by stairs tonight, though you can still take the other elevator to the 4th floor.

An Eclipse Tree Image Credit & Copyright: Shawn Wyre

Explanation: Yes, but can your tree do this? If you look closely at the ground in the featured image, you will see many images of yesterday’s solar eclipse – created by a tree. Gaps between tree leaves act like pinhole lenses and each create a small image of the partially eclipsed Sun visible in the other direction. The image was taken in Burleson, Texas, USA. Yesterday, people across the Americas were treated to a partial eclipse of the Sun, when the Moon moves in front of part of the Sun. People in a narrow band of Earth were treated to an annular eclipse, also called a ring-of-fire eclipse, when the Moon becomes completely engulfed by the Sun and sunlight streams around all of the Moon’s edges. In answer to the lede question, your tree not only can do this, but will do it every time that a visible solar eclipse passes overhead. Next April 8, a deeper, total solar eclipse will move across North America.
