Some have argued to me strongly that even if Loeb is wrong, he’s getting people interested in 3I/ATLAS and that’s a good thing for science. But Loeb isn't just wrong, he's recklessly following an old playbook that got 39 people killed in 1997. sites.psu.edu/astrowright/...

This weekend, especially on Friday and Saturday nights, the universe is expected to deliver an amazing show, in the form of the annual #Geminid meteor shower. #space #NightSky #astronomy www.theweathernetwork.com/en/news/scie...

A microphone on NASA's Perseverance rover has recorded the sounds of Martian dust devils whirling by, but also picked up a surprise — distinct snaps and pops indicating that tiny sparks of lightning were discharging from the dusty vortices as they passed. www.theweathernetwork.com/en/news/scie...

A spiral galaxy, observed with the Hubble Space Telescope in the GEMS survey. It is at redshift 0.65 (lookback time 6.21 billion years) with coordinates (52.86526, -27.96688). 136 volunteers classified this galaxy in Galaxy Zoo: Hubble.

Life can be extremely difficult to navigate. I'm lucky enough to have found my way. Maybe I can help you figure out how to find yours. badastronomy.beehiiv.com/p/what-works...

Spectacular aurora displays were seen across the Prairies and northern U.S. this week, including right over Winnipeg, where the night sky lit up in waves of green, purple and pink. https://ow.ly/84TU50Xo5vS

A volatile region of the Sun, crackling with flares and blasting solar storms into space, is setting us up for some intense space weather tonight, and in the nights ahead! #auroraborealis #northernlights www.theweathernetwork.com/en/news/scie...

My best shot of the Super Hunter's Harvest Moon from last night. I think this might be the best pic of the Moon my phone camera has ever taken, and yet, it's still not great. 😅

Despite the name, equal night and day does not happen on the #equinox. So, when does #equilux occur and why? www.theweathernetwork.com/en/news/scie...

The ringed planet, #Saturn, reaches "Opposition" this weekend, when it will be positioned on the exact opposite side of Earth from the Sun, and we will see the planet at its brightest in the sky since 2010! #NightSky #Astronomy www.theweathernetwork.com/en/news/scie...

Pythagorean Triple Square Day, as one man affectionately calls 9/16/25, is a day like no other this century.

Final reminder for early risers or late nighters, tomorrow morning the Waning Crescent Moon appears close to Jupiter. Will be a beautiful sight with Castor and Pollux too. Great photographic opportunity. 🔭 🧪 #astrophotography

As we approach the Fall Equinox, magnetic connections between the Sun and Earth ramp up the #NorthernLights, and we just witnessed a perfect example of this as brilliant #auroras lit up the skies. Plus, another round of auroras may shine tonight. www.theweathernetwork.com/en/news/scie...

An edge-on disk galaxy, observed with the Apache Point 2.5m Telescope in the SDSS survey. It is at redshift 0.008 (lookback time 114.4 million years) with coordinates (170.64746, 20.70392). 39 volunteers classified this galaxy in Galaxy Zoo 2.

A barred spiral galaxy in a merger, observed with the Apache Point 2.5m Telescope in the SDSS survey. It is at redshift 0.070 (lookback time 964.3 million years) with coordinates (230.03091, 11.86759). 43 volunteers classified this galaxy in Galaxy Zoo 2.

Why Canada is missing out on Sunday's Total Lunar Eclipse (and how to see it anyway) - hint, it happens Sunday _afternoon_ for us. Read the article for more info and a livestream of the event! #TotalLunarEclipse #Canada #astronomy www.theweathernetwork.com/en/news/scie...

New research appears to confirm lightning's extraterrestrial origin, due to cosmic rays hitting the top of the atmosphere. #weather #thunderstorms #lightning #science www.theweathernetwork.com/en/news/scie...

I've just added instructions for my #LEGO NASA InSight Lander to the Rebrickable site: #space #Mars #science rebrickable.com/mocs/MOC-229...

There's an article in EOS about my friend Tanya Harrison (@tanyaofmars.bsky.social) about her time 'roving on Mars'. 😁 eos.org/features/tan...

NASA's eye on the Sun, the Solar Dynamics Observatory, took a little break on Friday, to watch two different solar eclipses throughout the day. #space #solareclipse www.theweathernetwork.com/en/news/scie...

By the way... those overlapping #meteorshowers at the end of July? There's not two, but THREE of them! #Perseids #deltaAquariids #alphaCapricornids #space #astronomy www.theweathernetwork.com/en/news/scie...

It's #TaliTuesday, when I share pics of our Shepherd/Huskey/Heeler(?), Tali'Zorah! Here she is contemplated life's mysteries, her setting ambitious goals for herself, and her not being afraid to put herself out there.

The delta Aquariid and Perseid meteor showers are ramping up towards the end of July, producing overlapping displays in the sky. #astronomy #space #meteorshower www.theweathernetwork.com/en/news/scie...

Interstellar Comet 3I/ATLAS could be older than our Sun! #space #astronomy www.theweathernetwork.com/en/news/scie...

NASA is more than rockets and moonwalks. NASA is behind much of our everyday technology. From space discovery, to Air Jordans, to CAT scans, NASA has played a role. We get it all on less than a penny of every federal dollar. Now their science may be gutted by 50%. #NASADidThat

Sparklers hiss and pop with light. Firecrackers go bang. But when these two components are combined, that's when the real show begins: #Canada #CanadaDay #fireworks #science www.theweathernetwork.com/en/news/scie...

We are now seeing the very first images from the nearly completed Vera C. Rubin Observatory, and the results are truly mind-blowing. #astronomy #space www.theweathernetwork.com/en/news/scie...

"Atmospheric Warming & Planetary Wave Amplification" | I discuss our (@xuekeli.bsky.social et al) new article in @pnas.org demonstrating for the first time, an increase in incidence of the stuck & wavy jet stream patterns behind persistent summer weather extremes. michaelmann.net/atmospheric-...

My latest for American Scientist Magazine helps give scientists the tools to fight back against politicized charges that our research is silly or pointless- tools that will work whether you’re asked “why are we funding this” from your asshole uncle at Thanksgiving or an asshole US Senator. 🧪🌎

WIldfire smoke might cause this #FullMoon to look more like its namesake tonight. www.theweathernetwork.com/en/news/scie...

The Sun really went from 😟 to 😛

Another nice one!

One more share for the late night crowd 🧪

Oooo, that's a beaut!

No reason to leave the credit out of an image post, imo. There’s plenty of space to say that the bright blue dot is Earth seen from Saturn, and also credit the folks with the attribution they requested. CREDIT: NASA/JPL-Caltech/Space Science Institute

For the #LEGO fans out there, I now have instructions for 4 of my custom models on Rebrickable - City of Toronto, Sabine's speeder bike, my update to the Curiosity rover, and the MER Opportunity rover (scaled to Curiosity). All are free to download! rebrickable.com/users/Atonin...

Might be a good time to re up this old PopSci piece I wrote about how dirt cheap NASA missions are. www.popsci.com/real-cost-na...

My good friend (and one of the best DMs I've ever played D&D and other TTRPGs with) has a cool new game called Slay to Win on Kickstarter. Check it out! #gaming #ttrpg

The #Kosmos482 probe likely crashed down somewhere on Earth early Saturday morning. There is some idea where it may have come down, but no definite reports or sightings yet. www.theweathernetwork.com/en/news/scie...
