Comet C/2025 A6 (Lemmon) is currently in the constellation Ophiuchus, the serpent-bearer. It approaches the Sun (perihelion) on November 8.
⏲️ Use binoculars to look west after 7PM,
🌌 For the best chance of seeing it, go to regions that are darker and away from city lights.

2nd Nov. 2025 marks the 25th anniversary of the ongoing human presence off-world.

That is, humans have continuously occupied the ISS for exactly 25 years today.

So if you're <= 24 years old, you've never lived in a world where humans were *only* terrestrial-based.

Hubble Space Telescope images of interstellar comet 3I/ATLAS are out! These were taken 5 hours ago. Plenty of cosmic rays peppering the images, but the comet's coma looks very nice and puffy. Best of luck to the researchers trying to write up papers for this... archive.stsci.edu/proposal_sea... 🔭

We are excited to screen a kids show "321 Liftoff!" starting 9 August 2025.

Alan is a hamster who finds a robot which fell from the Earth’s orbit, and the robot’s spaceship is going to leave soon. Will Alan manage to get the robot back on their ship in time?

A significant new result about the structure of the Oort cloud came from visualizing simulation data a planetarium. Congratulations to the AMNH team!
coreyspowell.bsky.social Corey S. Powell @coreyspowell.bsky.social · Feb 23
Far beyond Pluto, trillions of cold comets circle the sun in a lazy swarm called the Oort Cloud. A new simulation indicates what this comet-cloud looks like: a loose spiral that resembles a miniature galaxy. 🧪🔭

arxiv.org/abs/2502.11252
The spiral structure in the inner Oort cloud viewed by a distant observer along the Galactic node direction (intersection of the Galactic and ecliptic planes). The distribution of bodies was obtained from the Galaxy simulation in Nesvorny ́ et al. (2023). To show things clearly, here we isolated the inner Oort cloud from the more spherical outer Oort cloud by plotting bodies, 34,000 in total, with a < 5,000 au. If the outer Oort cloud were plotted in the figure, it would appear as a large, roughly spherical envelope of the spiral. The classical Kuiper belt with r < 100 au is not shown here – it would appear as a doughnut-like central concentration of bodies aligned with the ecliptic plane.
