"Do you believe in aliens?" It's one of the top 10 astronaut questions. My answer: - belief is easy, real proof and understanding are hard - there's life on Earth and there are at least a septillion planets, so odds are there's life elsewhere too - we're incapable of visualising immense numbers, so time and distance fool us - we want to believe, so it biases our thinking - no one has conclusive evidence yet An excellent video - thanks @hankgreen for answering so well!

Can’t wait to see what’s next, my friend!! Feeling grateful today for my Artemis II crewmate and one of my closest friends @Astro_Jeremy. Jeremy and I have been on this journey together for 17 years. One thing that’s never changed is Jeremy’s character. He’s thoughtful, humble, steady under pressure, and the kind of person who makes everyone around him better. Those are the qualities that make him an incredible crewmate and an even better friend. As Jeremy transitions from a full‑time role at @csa_asc, I’m proud to watch this next chapter unfold.

Today, I am sharing a significant next step in my journey. This September, after 32 years of military service and 17 years as a Canadian Space Agency astronaut—culminating in the incredible privilege of flying around the Moon on Artemis II—I will be transitioning from my full-time role at the CSA. This is far from a departure. My commitment to seeing Canada thrive remains absolute. To ensure continuity in this mission, the Royal Canadian Air Force is enabling my transition into a Reservist role. This unique position is a deliberate launchpad designed to leave the door open for creative, ongoing ways to support and enable the vital work happening in Canada with respect to space, and I’m excited for the new challenges it will bring. Our future depends on a fierce continuation of Canadian innovation and exploration in space. The technological breakthroughs and economic benefits born from this sector are vital for our country and the world, and I am as determined as ever to push that work forward. To the Canadian Armed Forces, the CSA, NASA, our international partners, and my family: thank you. And to all Canadians: thank you for believing in what our country can achieve when we aim high. The mission continues. 🇨🇦

@NASAWebb @NASAHubble Tau ceti???

Though dust obscures background stars and galaxies, in @NASAHubble’s image of FS Tau (right) we can see protostar FS Tau b, its dusty protoplanetary disk, and its jet of matter (colored cyan). Compare to the Webb image on the left!

Gonna shine across that sky 🎶 In the infrared, Webb reveals bright protostars flowering from within the thick dust of the FS Tau star system. Set against a tapestry of background galaxies, this star-forming nebula is home to baby stars. science.nasa.gov/missions/webb/…
