Optical images from the Dark Energy Survey (DES) are amazing, ... so much happening in the galaxy group. Exploring the sky never gets boring 🤩 #extragalactic #AstroSci #astronomy #galaxies
This is very sad and shocking. I remember Carl from Mount Stromlo as we overlapped as grad students. He was really nice, and I even remember his dog named Yukon. So sad …
6 décembre 2025 – 36 ans après – Souvenir et recueillement
1/2 Nous continuons à nous souvenir des treize étudiantes et d'une membre du personnel de Polytechnique ayant perdu la vie le 6 décembre 1989 et des personnes qui en sont restées meurtries.

La recrudescence du discours masculiniste devrait-elle faire nous faire craindre un autre attentat contre les femmes?
We remember them always.

Two observations of the Sombrero galaxy are split diagonally, with Webb’s near-infrared observation at the left and Webb’s mid-infrared observation on the right. The galaxy is a very oblong disk that extends from left to right at an angle, from about 10 o’clock to 5 o’clock. The galaxy’s core is in the center. In the near-infrared image at left, the galaxy’s center glows white and extends above and below the disk. The outer edge of the disk is mottled brown clumps. In the mid-infrared image, the galaxy is light blue and clumpy, like clouds in the sky. There is an inner disk that is clearer, with speckles of stars scattered throughout. The background of space is black, scattered with tiny dots in a range of colors.
NEW: #NASAWebb has revisited the iconic Sombrero galaxy, this time in near-infrared light. The galaxy is strikingly different than the recently released mid-infrared view: webbtelescope.pub/4jrp4eW 🔭 🧪

Every student suicide is a tragedy, but it is a mistake to put the burden of preventing it on universities. Young people who aren’t students deserve to be supported too; they already have a much higher suicide rate. We need a joined-up societal approach.

One of the biggest issues I faced when trying to help students with mental health issues was the discontinuity in their support when they went home; placing more of the burden on universities rather than national health services just amplifies this issue.
Awesome talk, thank you Dr Hammel! 💫

Welcome back to Earth’s gravity Don Pettit! What a brutal way to celebrate your 70th birthday after 220 days off-planet.
Me in a flight suit, carrying a headset, walking across an airport apron, looking to the side at a yellow tailwheel airplane (a DHC-1 Chipmunk — a post-war trainer plane for the RCAF).
Had fun today doing some solo flying of the Chipmunk at the Canadian Aviation Museum in Windsor. Weather wasn’t good for anything but circuits but there were enough gusts to keep it interesting. (Photo courtesy of kind museum visitor Ani.) #flying #warbirds

Most of us watch the Moon at night. But the Moon spends nearly as many daylight hours above our horizon, though in bright daytime skies the lunar disk looks pale and can be a little harder to see. Of course in daytime skies the Moon also appears to cycle through its phases, shining by reflected sunlight as it orbits our fair planet. For daytime moonwatchers, the Moon is probably easier to spot when the visible sunlit portion of the lunar disk is large and waxing following first quarter or waning approaching its third quarter phase. And though it might look unusual, a daytime moon is often seen even in urban skies. Captured here in a telephoto snapshot taken on March 12, a waxing daytime Moon is aligned near the edge of a popular observation deck that overlooks New York City's borough of Manahattan.
