May’s edition of Ask An Astronomer (CTV News with @ginamartin.bsky.social) is up! Dr. Phil Langill and @astrogeo.bsky.social (Don Hladiuk) sit down with Gina to talk about Lunar Nuclear Reactors, Planet 9 and Artemis Il Up Close! Link to watch! 📺✨👀 youtu.be/GBKv_zu1UHc?...

I'm on the lastest episode of NPR's @outsideinradio.bsky.social this week talking about darkness and light pollution. 🌌✨ outsideinradio.org/shows/in-def...

Tonight’s Solar System grouping in the evening sky. The #Moon and #Venus formed a relatively tight pair while Jupiter far to their upper left was hanging out with Castor and Pollux, the brightest stars in Gemini. #astronomy

Tonight’s #sunset with a bonus #Moon and #Venus pairing. #timelapse #Abstorm #astronomy

This is a composite of the Moon, Mars, and Earth I made. The Moon and Earth are from Artemis II, and Mars is from the Psyche mission. Each image was taken *in the last six weeks*

A visit to Medicine River Wildlife Centre near Caroline AB and their bird patients and bird-friendly windows was part of the AstronoMay Star Party

Take a couple of minutes out to enjoy an aurora, from May 15, 2026. Two hours of Northern Lights compressed into two minutes! This was from Alberta. Details in the video description on YouTube. Enjoy! youtu.be/UxwEzulYsa0?...

The scale at which birds are directly killed by our built environment and the animals we surround ourselves with is hard to comprehend. ~2.4 BILLION birds killed by cats every year in the US, and ~600 MILLION killed by window strikes. repository.si.edu/bitstream/hand…

The first building to gain widespread attention for killing birds was Philadelphia's City Hall, which was the world's tallest building when it was completed in 1897. The architect / ornithologist William Baily started the first regular survey of window strikes at the building. 🪶🗃️

Fortunately there are ways to dramatically reduce bird deaths from building collisions! Turning lights off at night and using bird-friendly glass can reduce mortality by 60 to 90%. We don't need to be "content with fewer birds." birdhistory.substack.com/p/a-history-...

Last night’s ISS / Space Station pass was directly above our AstronoMay Star Party. It’s remarkable and sad how many other satellites photobombed this time exposure. 🔭

Wildfire season in Alberta. As devastating as it is, it does yield the most beautiful sunsets. #WildfireSeason #Alberta

Four a.m. this morning on Sunset Pass Road in Hansel Valley, Utah. This is the proposed site of the world-infamous Stratos hyperscale data center, which its builders estimate will require about double the energy currently used by the entire state of Utah. 1/2

‼️Help protect nocturnally migrating birds as they pass through your region by turning off all non-essential lighting from 11:00PM tonight until 6:00AM ‼️✊🐤🙌 high bird migration is expected in Chicago area next 3 nights, please keep lights out for birds, bats and insects

Forest fire smoke now visible from #Calgary

Forest fire smoke visible on radar near Burnstick Lake, west of Sundre this afternoon. This weekend’s predicted rainy (snowy?) weather should dampen things down. #abstorm

We’re super stoked for this event and Q&A with Colonel Joshua Kutryk (CSA Astronaut) hosted by @telus-spark.bsky.social! We’ll be there with our space loving shenanigans and some solar telescopes to add to the experience after the talk! ☀️🔭😎 More information: www.sparkscience.ca/csa-astronau...

#Astronomy #Skylights for this week, with worldwide content. Clear skies! (image by Claudio Oriani) astrogeo.ca/evening-venu...

Canvas & paper prints are available.

M44 is an open cluster located about 610 ly away in the constellation of Cancer. As it is so close it is best viewed with binoculars or wide-field telescope. It does appear to the unaided eye as a fuzzy patch in the sky. #astronomy

You're never too old to be a #WomanAstro. Went to the local science museum with a senior MeetUp group this weekend. My new friend looked at the Sun through a telescope for the first time. I ❤️ sharing the sky with others. 🔭🚀 #WomeninSTEM #WomeninScience

Following up on the news of the Tracy Arm landscape tsunami in 2025 had me looking into my archives. Turns out its been 20 years since I photographed the South Sawyer Glacier that was holding up the rock face. www.science.org/doi/10.1126/...

Extraordinary #WomanAstro! 🔭🚀 #WomeninSTEM #WomeninScience

Registration closes for this toward the end of this upcoming week. Grab your spot! ⛺️✨🔭

I can cross this item off my bucket list. I'm on CBC's Quirks and Quarks talking about our new paper in @science.org on the #TracyArm landslide tsunami (www.science.org/doi/10.1126/...). Tune in Saturday May 9, or listen here: www.cbc.ca/radio/quirks...

Solar rotation from Feb 23 to May 6th. Animation created automatically on SpectroSolHub, using the images I captured using an SHG 700, stacked with JSol'Ex. Jumps are because of missing observation days. Yet, you have more than 2 months of rotation here! #solar #astronomy #jsolex #spectrography

👀 As soon as the clouds cleared, I got these migrating birds on camera. #birds

Birds migrate through Colorado primarily at night, beginning 30 - 45 minutes after sunset, with peak activity between midnight and 5am. The vast majority of nocturnal migrants take flight shortly after dusk, navigating by starlight, and continue through the early morning hours. (Birdcast.org)

Some dramatic migratory #bird activity in the Worsley, Alberta region this afternoon. @calgaryresponse.bsky.social @fisherspeaks.bsky.social

Love the morning moon.

Some dramatic lighting and backdrop for the #Calgary Tower

We were down near Rochon Sands and heard snow geese all afternoon.

The #birds were migrating en masse in the Edmonton area this afternoon. (1/3)

Another Milky Way panorama, because some of this light traveled thousands of years across the abyss, only to land on my camera sensor. We might as well have a look at it.

#sciart Original is still available.

NGC 2024, the Flame Nebula, is an emission nebula located about 1350 ly away in the constellation of Orion. The very bright star in the image is Alnitak, the easternmost star in Orion's belt. #astronomy

I have a really nice (horrifying) image stack that one of my research team members made, that powerfully demonstrates what a huge problem satellite streaks are for wide-field imaging. This is a 3 hour stack of star-subtracted 5 minute exposures using the […] [Original post on mastodon.social]

Design tips for a night-friendly garden that will welcome moths, bats, beetles, fireflies, and other nocturnal species that emerge to feed, pollinate, and move through the landscape at night

I'm on this week's Light Pollution News podcast talking about all sorts of nocturnal topics! lightpollutionnews.com/podcast/reve...

On ‘Star Wars day’, researchers more than double the number of potential known ‘circumbinary’ planets like the fictional Tatooine, home to Luke Skywalker. www.theguardian.com/science/2026... #MayThe4thBeWithYou #STEM #SciChat #science #astronomy

Meet BatBot 🦇 - our new AI assistant at albertabats.ca! Find it under “FAQs & AI Assistant” on the homepage. Unlike general AI, BatBot uses trusted bat resources we’ve curated - so it’s tailored for western Canada. Ask it anything: bat houses, WNS, even advocacy tips! #HappyBaturday #BatBot

Birdathon kicks off today, and there’s never been a better time to join in and make a difference for bird conservation. Not sure where to start? This 6-step guide has you covered. Sign up and get started: www.birdscanada.org/birdathon #Birdathon #Birdathon50 #birdingforconservation

Here's an animated gif showing supernova SN2026kid in the edge-on spiral galaxy NGC 5907. Look for the star that winks on and off to the right of the center of the galaxy. I shot the galaxy back in March and earlier this week under bright moonlight. 🔭 Tip of the hat to @rami.spaceaustralia.com

Once the sky is dark enough, find Spica about two fists upper right of the Moon, and brighter Arcturus about four fists to the Moon's upper left. Meanwhile, Venus shines in the western sky in twilight. Now it's above Aldebaran and the delicate Pleiades. skyandtelescope.org/astronomy-ne...
