M93 is an open cluster located about 3400 ly away in the constellation of Puppis. Open clusters are found in the Galactic plane and are the result of relatively recent star formation in the arms of our Galaxy. #astronomy

M40 is an optical double star located in the constellation of Ursa Major. It is an optical double because the stars are only close in our line of sight. One star is 470ly away while the other is 1010 ly away. The stars themselves are not associated. #astronomy

M105 (centre right) is an elliptical galaxy located about 36.6 Mly away in the constellation of Leo. Unlike spirals which are disk shaped, elliptical galaxies are balls with no defined internal structure. The can vary in shape from spherical to a flattened ellipse. #astronomy

M17 is an emission nebula located about 5500ly away in the constellation of Sagittarius. Emission nebulae usually glow due to hot stars inside them that have recently formed. The UV light causes the gas of the nebula to glow. #astronomy

NGC 7662 is a planetary nebula located about 5700 ly away in the constellation of Andromeda. It is the remnant of a low to intermediate mass star (1-6 solar masses) having blown off its outer layers, forming the nebula. #astronomy

M46 is an open cluster located about 4900 ly away in the constellation of Puppis. The cluster contains about 500 stars spread over a radius of about 37 ly. The planetary nebula NGC 2438 is not a member of the cluster as it is only about 1400ly away so it a foreground object. #astronomy

M95 is a barred spiral galaxy located about 33 Mly away in the constellation of Leo. The central bar of stars is common amongst spiral galaxies. Our own Milky Way galaxy is a barred spiral.

Abell 2666 is a cluster of galaxies about 340 Mly away in the constellation of Pegasus. Most galaxies tend to be in clusters, gravitationally influencing each other. The larger galaxies in the image are part of the Abell cluster. #astronomy

The Double Cluster is a pair of open clusters (NGC 884, left, and NGC 869, right) located about 7500 ly away in the constellation of Perseus. #astronomy

Comets are icy messengers from the farthest reaches of the solar system. The short period comets (p<200 years) originate in the Kuiper belt past the orbit of Neptune. The long period comets originate from the Oort cloud, which extends to nearly a light year away from the Sun. #astronomy

Trump-loving Alberta Conservatives take note. US access to Venezuelan oil will kill your industry with raw product cheaper to transport and no technical processing changes. #cdnpoli #ableg

Extremely funny to call the pope “holier-than-thou”

I'm sure #TeamVeggie who called for more CO2 will be happy to update their position on this critical issue, now that they have this information... Perhaps not.

M11 is an open cluster located about 61oo ly away in the constellation of Scutum. Open clusters are groups of stars that were formed more or less at the same time in the same star forming nebula. This makes them useful in the study of how stars evolve through their lives. #astronomy

The one where we showed the world what Rubin can do...and, wow 🤩 On June 23, NSF–DOE Rubin Observatory unveiled its First Look images! These large, detailed images showed why Rubin's 10-year survey will revolutionize our understanding of the Universe. 🌌 #RubinRecap2025 🔭🧪

No big deal, but the Alberta government just increased the fee to submit a citizen initiated petition from $500 to $25, 000. After the separatism initiative was approved, but before Corb Lund's coal mining petition gets re-approved. No political shenanigans going on here.

M1, the Crab nebula, is a supernova remnant located about 6500ly away in the constellation of Taurus. The supernova that created M1 was observed and recorded by Chinese astronomers in 1054. The actual explosion would have happened 6500 years earlier. #astronomy

A wee bit blizzard-y outside.

M24 is a star cloud located about 10kly away in the constellation of Sagittarius. Not an object per se, but a hole in the dust and gas of our Galaxy. We are seeing millions of stars deep into the Galaxy. #astronomy

M26 is an open cluster located about 5200 ly away in the constellation of Scutum. It is a relatively young cluster at only 83 million years old. #astronomy

M30 is a globular cluster located about 27 kly away in the constellation Capricornus. Though globulars are common (at least 150 around our Galaxy) and orbit other galaxies, we don't have a clear idea of how they were formed. #astronomy

NGC 5826 is a planetary nebula located about 2000 ly away in the constellation Cygnus. It contains FLIERs (Fast Low Ionization Emission Regions) which can be seen going down and left and up and right. #astronomy

M109 is a barred spiral located about 67 Mly away in the constellation of Ursa Major. It is the largest galaxy in the M109 group of galaxies which contains about 50 galaxies. #astronomy

NGC 2438 is a planetary nebula located about 1400 ly away in the constellation of Puppis. At first glance NGC 2438 appears to be part of the open cluster M46, however M46 is about 5000 ly away so the PN is very much a foreground object. #astronomy

M9 is a globular cluster located about 26 kly away in the constellation of Ophiuchus. Though 26 kly from us, it is only 5.5 kly from the centre of our Galaxy making it one of the closer globular clusters to the Galactic core. #astronomy

M51 is an interacting galaxy pair located about 24 Mly away in the constellation Cannes Venatici. The main spiral is interacting with a smaller galaxy located at the end of one of the spiral arms. #astronomy

"Even Carrington would be impressed" 😬 https://spaceweather.com/archive.php?view=1&day=02&month=12&year=2025 Hopefully we just get "someone should check on our satellites" levels of auroras and not "A bunch of open questions in solar-terrestrial physics are about to be answered"

M6 is an open cluster located about 1600 ly away in the constellation Scorpius. The cluster contains about 120 members, which as a an open cluster means they were all formed about the same time in the same nebula. #astronomy

Stephan's quintet is a cluster of galaxies located in the constellation Pegasus. Of the 5 galaxies, NGC7320 (lower right galaxy) is only 39 Mly away, while the others are on the order of 300 Mly away. #astronomy

NGC 6058 (blue object, centre) is a planetary nebula located about 11 kly away in the constellation of Hercules. Planetary nebulae are the penultimate stage of evolution of stars like our Sun. The star has blown off its outer layers and the remnants of the core cause that gas to glow. #astronomy

Uranus is the 7th planet from the Sun in our Solar System. About 4 times the diameter of the Earth, Uranus is classified as an Ice giant as it is made primarily of ices of gases like methane and ammonia. #astronomy

M13 is a globular cluster located about 24 kly away in the constellation of Hercules. One of the more spectacular globular clusters visible in the northern hemisphere, it is relatively easy to find once you find the constellation Hercules. Looks good even in binoculars. #astronomy

M28 is a globular cluster located about 18 kly away in the constellation of Sagittarius. As with most globular clusters there appears to be no active star formation as the stars in the cluster are all cool, older red stars with no young blue stars. #astronomy

M78 is a reflection nebula located about 1350 ly away in the constellation of Orion. We see reflection nebulae because the light from a nearby star is bouncing off the gas and dust of the nebula. #astronomy

The Milky Way is a glowing band seen across the sky. This band is made up of untold millions of stars in our own Galaxy. Since our Galaxy is a spiral or disk galaxy and we live in the disk we see it as a band across the sky. #astronomy

M104 is a spiral galaxy located about 9.5 Mly away in the constellation of Virgo. M104 is known for its prominent dust lane, visible across the galaxy image. We can see this as the galaxy is nearly edge-on to our view. #astronomy

IC 1747 (blue dot in the line of stars at centre) is a planetary nebula located about 9800 ly away in the constellation of Cassiopeia. IC stands for Index Catalog, a supplemental catalog to the NGC catalogue, released about 15 years after the NGC. 1747 is the PN's number in the catalog. #astronomy

What could possibly go wrong with AI designing and operating nuclear power plants…

NGC 4647 (smaller of the two galaxies at centre) is a spiral galaxy located about 57 Mly away in the constellation of Virgo. It seems to be starting to interact with M60 (larger of the two) which is only about 600 kly away from it. #astronomy

@djclimenhaga.bsky.social: Trying to challenge the UCP government’s misuse of the Charter’s notorious notwithstanding clause may be a waste of time and money, but using the UCP’s ridiculous recall legislation as a strategy against the perpetrators is clearly rattling Premier Smith. #abpoli

NGC 3384 (galaxy at top of triangle of galaxies) is an elliptical galaxy located about 35 Mly away in the constellation of Leo. As with most elliptical galaxies, NGC 3384 is made up of mostly older Population II stars. These stars are cool red stars that have very long lives. #astronomy

They shall grow not old, as we that are left grow old: Age shall not weary them, nor the years condemn. At the going down of the sun And in the morning We shall remember them.

108 is a barred spiral galaxy located about 46 Mly away in the constellation of Ursa Major. It has been observed to have over 200 globular clusters in orbit about it. #astronomy

Well this is interesting: evl.link/t6

Saturn is the 6th planet in our solar system, famed for it's spectacular ring system. As the rings are inclined to the plane of Saturn's orbit, we see them at different angles through the years. Here we see the change from 2019 (L) to 2025 (R). #astronomy

Mars is the fourth planet from the Sun in our solar system. It's red appearance is due to a large amount of iron oxide dust on its surface. #astronomy

M41 is an open cluster located about 2400 ly away in the constellation of Canis Major. Open clusters are great natural laboratories for stellar evolution. Since the stars were formed roughly at the same time, we can see how different stars evolve over time. #astronomy

Scientists say the return to "standard time" is good for our health. But the time change can be disruptive and we must also adjust to more winter darkness. Syncing our habits to our body clock helps.

M60 (bright galaxy centre) is an elliptical galaxy located about 56.7 Mly away in the constellation of Virgo. It is one of the brightest galaxy in the Virgo cluster. The smaller spiral galaxy beside it is NGC 4647. The pair are listed as Arp 116 in the Atlas of Peculiar Galaxies. #astronomy
