I was asked to join in a series of blog posts about the importance of public lands, so I wrote about how the Grand Canyon, and the Solar System, is so much more than a checklist of things to see. It inspires us to ask questions, learn, and grow: www.grandcanyon.org/about/news/g...

Oh hey, happy equinox. For me it's always a nice reminder to ponder the interrelatedness of everything on Earth. The cosmos is lots bigger than us, but this is still the only home we know. What we do here matters.

Due to a few cancellations, we have some last-minute availability for Astronomy Nights over the next week. Three tickets are available for Thursday, March 13, and two for Tuesday, March 18th. Book your visit today! www.denverastro.org/public-night... @chamberlin-obs.bsky.social

Astronomers discover 128 new moons orbiting Saturn

What’s Up in Denver? March 10th through 16th, 2025 Total Lunar Eclipse, 3 Virtual Lectures, DAS Astronomy 101 begins, DAS Spring Banquet, the Gibbous moon makes its way across the sky, and more. www.denverastro.org/whats-up-in-... #denverastro #das #astronomy #eclipse

TONIGHT!!! The planets await!

Hello, Mercury! 🪶 #planets #astronomy

Hey! All the planets are still visible tonight, and will be for one or two more (Saturn is getting lower and more difficult but Mercury is still getting higher, closer to Venus every night) so go out and look after sunset!

Good news about viewing the #planets from #Denver (or anywhere): the #alignment or #parade is not over! 🪐 You'll still be able to see multiple planets for several more weeks! Come to our open house / planet-gazing event on SATURDAY MARCH 8 to catch some of them through a telescope! 🔭

Hi friends, here is a script for calling your representatives to express support for the federal indirect grant costs that support the observatory. Recommend contacting your 2 Senators, 1 Congressperson, and the state Attorney General.

#Denver #astronomy fans, come on over to Chamberlin Observatory for our open house tonight! It may be cloudy, but we still have a chance of seeing the Moon 🌓 and Venus 🟡. You can also tour the historic building! FYI, we are partly supported by federal grant funding. 💖

Particularly good evenings to look up: 1/31 and 2/1: crescent Moon 🌒 is near Venus and Saturn 2/6 through 2/9: waxing Moon 🌔 is near Jupiter and Mars #Denver folks, join us on 2/8 for our next open house event and telescope viewing! We may also spot Uranus 🔵 and Neptune 🟢!

In light of this deeply illegal activity at NSF and the ongoing attack on American science, I'm posting the slides from my 2017 talk at the American Physical Society about the Nazi take over of German physics/why German is no longer science's lingua franca 🧪 🧵 1/26 drive.google.com/file/d/1_MCm...

Hey, I recognize that star! Go to the link to see the shells move! (h/t @emmalieb.bsky.social)

Keep your eyes open for lots of #planets in the night sky over the next several weeks (not just tonight)! Venus 🌟 and Saturn 🪐 are in the SW at sunset. Jupiter 👑 and Mars 🔴 are rising in the east at dusk and up all night. All are easy to see, and Saturn & Jupiter look great through binoculars!

Paper (and press release) week! 🧪🔭 I'm so excited to share this awesome research result from @emmalieb.bsky.social and me, in a collaboration between @uofdenver.bsky.social and @noirlabastro.bsky.social. We made a JWST time lapse to watch the dust shells around WR140 expand!

#Denver, did you see Mars 🔴 blink out behind the Moon 🌕? Watch for it to reappear in an hour, just before 8pm!

More fun astro-news: the Moon will occult Mars tonight for folks across the US! No special equipment required, just go out and watch the red planet disappear! 🔴🌕 www.space.com/stargazing/t...

Super cool news from @uofdenver.bsky.social astronomers!

Sorry, #Denver #astronomy fans, we had to cancel tonight's open house and stargazing event because of incoming winter weather. You get snow tonight instead of stars! ❄️❄️❄️ Next open house event is Saturday, February 8. Hope to see you there!

Think twice before gifting someone an M dwarf this holiday season

just remember this isn’t earth… it’s a COMET!!

It pays to know your constellations! 😎
