A reminder that our public Spring events start this week!

Public nights are here!

The brown dwarf W1935 is a bit of a mystery. Astronomers using the James Webb Space Telescope picked up glowing methane—a sign that the object’s upper atmosphere is being heated. But the brown dwarf has no host star, so where could the heat be coming from?

In our solar system, Jupiter and Saturn show methane emission due to the presence of auroras—what we call the Northern Lights on Earth. W1935 might also have auroras, which could be powered by energetic particles from a nearby, active moon, like Jupiter’s Io: https://webbtelescope.pub/4aKMkBF

IC 4592: The Blue Horsehead Reflection Nebula Image Credit & Copyright: Antoine & Dalia Grelin

Explanation: Do you see the horse’s head? What you are seeing is not the famous Horsehead nebula toward Orion, but rather a fainter nebula that only takes on a familiar form with deeper imaging. The main part of the here-imaged molecular cloud complex is reflection nebula IC 4592. Reflection nebulas are made up of very fine dust that normally appears dark but can look quite blue when reflecting the visible light of energetic nearby stars. In this case, the source of much of the reflected light is a star at the eye of the horse. That star is part of Nu Scorpii, one of the brighter star systems toward the constellation of the Scorpion (Scorpius). A second reflection nebula dubbed IC 4601 is visible surrounding two stars above and to the right of the image center.

Happy fun fact Friday!

Did you know that the largest canyon system in the solar system is Valles Marineris on Mars? The image shows the Valles Marineris compared to the US coast to coast and the Grand Canyon!

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!

Wed. Nov. 15 - We will be closed tonight due to cloud cover.

Yuck:

Did you know that there are 5 known dwarf planets in our solar system? Everyone knows Pluto, but there is also Ceres, Haumea, Makemake and Eris.
