This isn't all I'd hoped it would be, due to less than ideal sky conditions and an equipment issue. But this is the transit of Titan and its shadow on Saturn. Ideally the photograph would resolve the moon from its shadow, but I'm still hoping for points for effort. #Astronomy #Astrophotography

Captured. Someone did manage to catch the penultimate shadow transit of Saturn’s large moon Titan early this AM. Robert Lunsford was able to nab the event from southern California, seen in this sequence: spaceweathergallery2.com/indiv_upload...

What a shot! 💫

Gorgeous! 🌓✈️

Wow! These are beautiful and also really interesting - look at the clouds (dust storm?) in the second image. And the volcanoes are 🤌 #mars

That was a GAME. And this guy (41-yr old Matt Prater) kicked the game winner as time expired in his first outing as a Buffalo Bill! 🏈 #BuffaloBills

This is a new image of comet 3I/ATLAS, showing the development of a long tail of dust and gas as the object gets closer to the Sun. As a reminder, the "I" in 3I/ATLAS stands for "interstellar". Because this comet formed around a different star and is OLDER THAN THE SOLAR SYSTEM

There are 25 days left in September. Thanks to Patreon + Twitch + podcast ads + one-time donations, we are within $1,288 of hitting our $116k budget for the year (FY25). Can you please donate today so we can end the year in the black? planetaryscienceinstitute.kindful.com?campaign=132...

Yes, but this driver wouldn’t have seen a dump truck driving through a nitroglycerin plant. Terrifying!

CHEESES (Palindrome) Decide "No edam," I did. I ate feta, I did. I made one diced.

☄️ News from the @esa.int Planetary Defence Office: The number of known near-Earth asteroids has just passed 39,000! This figure is particularly impressive when we consider that 25 years ago we only knew of around 1000.

Where to begin… am seeing lots of flap around ye’ ole web around today’s New Moon as a ‘Black Moon’… yes, today’s New Moon occurs at 6:06UT/2:02 AM EDT. This happens every 29.5 day lunation, as the Moon laps the Sun in the sky. Let me break down the whole ‘Black Moon’ backstory.

If you think trusting the experts is bad, wait until you trust the amateurs…

Portrayed so well by Tom Hanks in 1995, the real Jim Lovell led a pretty amazing 97 years on Earth and in space. He was the first to visit space 4 times and got to see the moon up close twice - the only person to do so without ever landing. 🚀 🌕

More observations needed but this would be a very cool discovery with potential moons in the habitable zone! 🪐🌑

13 years of roving Mars had taken its toll! Image captured 12 hours ago by Curiosity. #Mars Aug. 6, 2025 - Sol 4621 🧪🔭 Credits: NASA/JPL-Caltech/MSSS

In addition to the cool glory, this clip reminds me how flying through clouds/contrails always looks so “3D”!

Look at this photo taken by astronaut Don Pettit! 😮 “3 galaxies at once! I photographed the Milky Way and both Magellanic Clouds in this star field from the SpaceX Crew 9 Dragon, on my new mission to the ISS.”

It’s not aliens. It’s never aliens.

This is a type of rock called a banded iron formation. It's made of alternating layers of iron oxides (magnetite and haematite) and silica (chert and chalcedony). It's 3.2 billion years old. And it formed before life had oxygenated Earth's seas and atmosphere. It's almost from another planet.

Oh my

Wow! Betelgeuse is a double star! Its companion has been discovered by the Gemini North telescope, of which Canada is a partner.

Oh no! Very sad to hear this.

Wiggly aurora in Churchill, Manitoba. One of the coolest formations I’ve seen.

Oh no! His jump in 2012 was incredible to watch live.

Beautiful Martian closeup!

Call to backyard astronomers: if you were recording Saturn July 5th check your videos for a potential impact flash! #saturn

King of palindromes.

That small dot moving left to right is 3I/ATLAS. It's a comet that was discovered on 1 July 2025. It's travelling at 58 km PER SECOND and isn't gravitationally bound to the Sun. Which means you're looking at a comet that formed around another star, passing through the Solar System.

Hi, moon! Taken with an iPhone 14 Pro Max. 🌓📱

We have a visitor! This is only the third-known comet to come from outside our solar system. Almost impossible to imagine how long and boring its journey has been until now! ☄️

Astronomy news always breaks over morning coffee. A new object, given the provisional name A11pl3Z discovered by ATLAS on July 1st is the 3rd such interstellar interloper known. @universetoday.com - www.universetoday.com/articles/inb... Thx @filipp-romanov.bsky.social @astrafoxen.bsky.social

Look at all those galaxies!

Absolutely stunning video of a Antarctic gonate squid captured during an expedition aboard the R/V Falkor (Too). It's never been seen alive before! Read more in the New York Times: www.nytimes.com/2025/06/11/s... Video: ROV SuBastian/Schmidt Ocean Institute, courtesy of National Geographic 🦑🌊🧪

Nearly all of Atlantic Canada visible!

In 2001 an astronaut asked me for directions. (It was the wonderful Chris Hadfield and he asked me for the best way to get from where we were to downtown Ottawa)

God only knows what pop music would have sounded like without Brian Wilson. A gentle giant who created so many classics and influenced countless artists. 💔

Canada’s wildfire smoke has now made it to Europe! Gives you a sense of how massive these fires are!

Everything that’s happened over the past six months has been a response to an imaginary crisis. There is no immigrant invasion. No trade crisis. No scientific or governance crisis. Just people completely high off their own supply trying to fundamentally reorder society. None of this had to happen.
