Happy vernal equinox! You may know this as one of 2 dates when the day and night are roughly equal length, or as the beginning of spring in the northern hemisphere and fall in the southern. But to astronomers, the vernal equinox has an additional fun significance... 🧪🔭 (1/8)

🚫 OPEN HOUSE CANCELLED FOR 1/24 🚫 Sorry, #Denver, no stargazing this Saturday due to unusually cold weather in the forecast! 🥶 Yep, even astronomers get cold feet sometimes. See below for an alternative indoor astro-event! Next open house is February 21 -- hope to see you there!

Denver Astronomical Society 🔭@denverastro.bsky.social · 7mo ago

Our Jan 24th Open House has been canceled due to bitterly cold temperatures with snow Friday night into Saturday. Instead, consider joining Standley Lake Stargazing from 5:30 - 6:30 PM for an indoor astronomy session. Details are here: www.arvadaco.gov/Calendar.asp...

A wintry nighttime view of a red brick observatory building topped with a silver dome. The sky is dark blue and starry, with the constellation Orion hanging above the dome. A welcoming yellow light illuminates the path and steps, and snowy pine trees frame the scene.

What to expect: 1) The show continues overnight 2) There’s a chance that tomorrow night’s northern lights show is even better than tonight’s (more below). (Disclaimer: I am not a space weather meteorologist, but the folks below are, and I did stay at a Holiday Inn Express)

🚨HEY DENVER, GO LOOK AT THE SKY!!! 🚨 Never seen aurorae this good before. 🤯 They were totally naked-eye around 9:45pm from south Denver, bright red and green. They're coming and going, so if you don't see anything at first, try again later! Pics with an iPhone 13, 3-sec exposures

#Denver stargazers: come on over for an open house and star party with @denverastro.bsky.social TONIGHT, starting around 5pm! www.denverastro.org/events/open-...

Wide-shot time-lapse photograph of DU's historic Chamberlin Observatory at night. Above the dome to the left is Polaris, the North Star, and the other stars of the night sky are circling around it. The building is dimly lit, and red light can be seen in the windows upstairs inside the dome, which is open to the south. Tall pine trees surround the building.

A bright comet seen against a dark starry background, taken with my Seestar smart scope. The head of the comet at lower left is fuzzy and faintly greenish; the tail extends to upper right and includes a brighter central streak. The caption labels it "C-2025 A6, 3 min" and gives the coordinates of the observing location.

Interior of the University of Denver's historic Chamberlin Observatory. A long white telescope stands on a black pillar in the center of a round room with brick red walls and a curved gray ceiling. The telescope is pointing out an opening in the dome toward a dark blue sky. People are standing around the room waiting their turn to climb a ladder at right that allows them to look through the telescope.
