A Personal Item Was Found On The Observatory Decks The Day After Our Public Night. If You Lost Something,

Picture of the Day!

This image is composed of consecutive shots taken near Llers in Spain’s Girona province, showing Comet Pons-Brooks. After passing closest to the Sun, it is now fading as it moves into the southern skies toward the outer Solar System.

How Gravity Warps Light - NASA Science

Gravity is obviously pretty important. It holds your feet down to Earth so you don’t fly away into space, and (equally important) it keeps y

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.

3/26: Public night is cancelled tonight due to clouds. We'll try again next week.

Every February 2, we wonder if Punxsutawney Phil will see his shadow.

In Saturn’s case, astronomers know some of Saturn’s moons will cast shadows across the planet’s iconic rings every 15 years. This effect only occurs when the planet’s rings are perpendicular to the Sun. The next time this will happen is in May 2025.

Watch as four of Saturn’s moons orbit the planet, based on images taken by the Hubble Space Telescope over a 9.5-hour span in 1995. Enceladus is first and Mimas is close behind. Both of these moons cast small shadows on Saturn, but among the two, only Enceladus’ shadow cuts across the rings. Dione follows next and casts a long shadow across the planet’s rings. About 12 seconds in, the moon Tethys moves swiftly behind the planet toward the right.

If galaxies could talk, we’d want to ask for this galaxy’s skincare routine!

Meet I Zwicky 18, a galaxy lying 60 million light-years away in the constellation Ursa Major.

The bluish-white knots in the center are regions where stars are forming at a rapid rate. These large hubs of stellar creation and the lack of heavy elements in the surrounding gas caused astronomers to think that this dwarf irregular galaxy was very young, since it resembles galaxies in the early universe.

However, the Hubble Space Telescope revealed that I Zwicky 18 is more mature than it first appears. Hubble found faint, older stars within the galaxy, indicating that I Zwicky 18 has been forming stars for more than a billion years.

ALT TEXT: A bright white and blue oval-shaped area takes up most of the view and is largely centered. Cloud-like wisps of blue material surround the bright-white center, forming a fluffy wreath-like shape. The fluffy material begins as light blue near the center and gradually darkens moving outward. Stars, seen as many bright white and yellow small points of light, are densely grouped in the white and light blue region, forming two roughly circular clumps, one in the upper left and one in the lower right. The corners of the image are dark and mostly empty, with a few larger, fuzzy yellow points of light scattered infrequently throughout.

We're not yet sure about tonight's weather - it depends on whether these clouds move north or south. Check back in a few hours!

4/2/25: We'll be closed tonight due to clouds and rain. We'll try again next week.

We sure have been experiencing this around here. Not only has it affected temperatures, but the percentage of time the sky is cloudy. Our observatory takes images and hosts events less often in part because of the conditions of our sky.

So many people do not understand the relationship between climate change and cold weather.

We'll be open tonight, Wed. 4/23, 8:30 - 9:45 pm! We expect lovely skies.
