Castor and Pollux lie above #Jupiter while the Crescent #Moon and #Venus glide over the horizon. #astronomy #astrophotography

Managed to capture #comet C/2025 R3 (PANSTARRS) on the eastern horizon during a narrow viewing window before sunrise. Its next pass will be in 170,000 years! #astronomy #astrophotography

Check out my 12 panel, 71 hour mosaic of the Large Magellanic Cloud in both broadband and narrowband: app.astrobin.com/i/7thh0y Go full screen & zoom in! I presented it at NEAIC/NEAF for the first time yesterday and it was the main subject of both of my talks. #astronomy #astrophotography #space

Splashdown!

Coming home soon!!! #artemis #splashdown #nasa

Galaxy season is here! Here’s an edge-on (NGC 4013) and face-on spiral galaxy (NGC 3938) combo. They are located near Ursa Major. @kat-astro-bot.bsky.social #galaxy #astronomy #astrophotography

I was on CBC-KW this morning to chat about #Artemis II and got a lovely view of the waning gibbous Moon on my way in to work afterward. We have such a pretty satellite 😍 BTW, did you know NASA has a Daily Moon Guide with Moon-viewing tips & info? science.nasa.gov/moon/daily-m...

“Amaze! Amaze!…” “Copy, Moonjoy…” — Artemis Mission Control to Integrity Great images from #NASA of impact crater Mare Orientale, now in full view. Blue line is a very rough estimate of where far and near side meet. Its position changes due to lunar libration. #artemis #astronomy #space

NASA #Artemis II flyby coverage schedule; all times in Eastern. You can follow along live on NASA+ (plus.nasa.gov) or on the NASA YouTube channel (www.youtube.com/@NASA). It should be amazing to watch!

There's a nice #Artemis II mission tracker here: artemis.cdnspace.ca LOTS of data about its current position, crew activities, and whether or not the toilet is currently "Go"

OK this is cool. The first time humans have seen the whole Mare Orientale on the far side of the Moon with their own eyes. See flic.kr/p/2s5HA2X 🧪🔭

The whole-Earth-at-night photo from the #Artemis II mission was brighter than many expected. That was mostly due to camera settings; here’s another pic taken just before with diff settings. Digital photography is always subjective—even before processing! (HT @swapnakrishna.com @jasonc0.bsky.social)

Let’s unpack the picture taken from NASA’s Orion after translunar injection by Reid Wiseman. See alt text. This shot was taken with a Nikon D5 DSLR at ISO 51,200 which is why it is grainy. See also @astrokatie.com’s video annotation. www.instagram.com/reel/DWryhfx... #artemis2 #astronomy #space

It’s #Artemis II day. Aptly, on the #Moon, a cat seems to lurk. #astronomy #astrophotography #felixthecat #artemis2

NSF–DOE Rubin Observatory has officially started releasing world-public alerts! 🎉 Here's what you need to know about these first alerts and what's coming up for Rubin ➡️ 🔭🧪☄️

The largest spot-the-difference effort EVER has begun!🚨 On the night of Feb 24, NSF–DOE Rubin Observatory officially released its first ~800,000 public alerts of detected changes in the night sky!🔍 A new era of discovery is here✨ 🔭🧪☄️ 🔗: rubinobservatory.org/news/first-a...

Eyes of Clavius and Rupes Recta are revealed tonight along the terminator of the waxing gibbous (69%) moon. Jupiter’s main bands also appear after stacking many frames taken at low exposure. #astronomy #astrophotography #moon #jupiter

The #SuperbOwl Nebula! 🏈 #astronomy #astrophotography

Regulus (alpha Leonis, magnitude 1.4), the brightest star in Leo, subtly reappears after its lunar occultation on Feb. 2, 2026. Video stacked with #seestar S50. #astronomy #astrophotography #occultation #moon

I have had my Orion ShortTube 80 refractor for 30 years. I used it a lot in the 90s with a film camera. Now it is relegated to guide scope duty attached to a ZWO ASI178MM camera. Last night I let them show what they can do on the waxing gibbous moon. Not bad! Details in ALT. #astrophotography

Two stars, two galaxies, two clusters: Canopus - 2nd brightest star (and the home star of Arrakis in Dune) Achernar - 9th brightest star Large and Small Magellanic Clouds - dwarf irregular galaxies NGC 2516 - open cluster 47 Tucanae - globular cluster #astronomy #astrophotography #arrakis #dune

Southern skies under Bortle 2 skies. Omega Centauri (green), Southern Cross (red), Alpha Centauri (yellow) in the Milky Way.The Large and Small Magellanic Clouds are also visible with the naked eye. #astronomy #astrophotography #southerncross #milkyway

The luminous red #nova (LRN) AT2025abao in the Andromeda #galaxy was discovered by Koichi Itagaki on 10/17/25. Here is M31 on 6/25 vs 11/14 this year imaged with a #Dwarf3 telescope. The lower right inset shows the bright nova after the merger of two stars. #astronomy #astrophotography

The brightest crater on the moon stands out during the waxing gibbous phase (~89%). The relatively young Aristarchus crater was formed 450 million years ago. #moon #astronomy #astrophotography #seestar

Timelapse of Two Travelers — Lemmon orbits with a majestic and dynamic tail spanning a few degrees. SWAN silently sails with almost no tail yet proudly marks its presence with a green glowing nucleus, a signature of diatomic carbon. #comet #astronomy #astrophotography #space

An H-alpha image of the #Sun on Aug. 30. Left: result from raw images aligned and stacked. Right: color rendering of the left image in Photoshop to bring out the prominences. On the disk are spicules or “fur”, filaments and plage (white regions near sunspots). #astronomy #astrophotography

Neptune and Saturn imaged with the #Dwarf3 telescope on August 12. Two of Saturn’s larger moons,Titan and Iapetus, were discernible. #astronomy #astrophotography

2 Pallas, the 3rd largest asteroid in the solar system, is now in the constellation Delphinus. It will be in opposition and at its brightest on 8/10. Currently, it is at magnitude 9.4. The brightest star in each image is Saulocin. #astronomy #astrophotography #dwarf3 #asteroid #minorplanet

Seyfert’s Sextet, found between Hercules and Serpens, consists of 5 galaxies and a long tail of stars of one of them. NGC 6027d is not gravitationally related and is actually 955 million LY away! The other 5 are only 190 million LY away. Such old photons! #dwarf3 #astronomy #astrophotography

The Crab Nebula (M1), the remnant of a supernova that exploded on July 4,1054. It is 6,500 light years away and found in the constellation Taurus. #astronomy #astrophotography #seestar #fourthofjuly

A night sky of wonder and beauty: a New Moon, a War God hounded by Bees (Mars and the Beehive Cluster), a Thousands Suns next to a seeming Obsidian Void (M9 and Barnard 64)

In the Great Hercules Cluster (M13), three relatively dark lanes nearly 120 degrees apart seemingly form a propeller. This was first reported by Bindon Stoney in 1850. Globular clusters may look the same but each has its own special traits. #astronomy #astrophotography #dwarf3

Happy #EarthDay, fellow space travellers!
