Notes: all images above are colorised and are a single shot, not a composite. More info on the related links.

An image taken from orbit shows the potato-shaped satellite Phobos orbiting above Mars. The perspective shows Phobos very close to the Martian limb. Phobos appears predominantly grey, while the surface of Mars displays tones ranging from rusty red to the bluish hue of its external atmosphere layer. Craters on Mars are larger than those on Phobos.

Happy birthday to Caroline Herschel (1750 – 1848) a trail blazing woman in #astronomy. Hers was a real life Cinderella story, where rather than marrying a prince, she made a life and career for herself. Marriage her expected role but she was deemed unmarriageable, since a childhood bout of typhus stunted her growth. Her mother thought she should train to be a servant, & purposely stood in the way of her learning French, or music,🧵

A couple years ago #NASA had an article answering a common question about how many digits of pi they use for their calculations. While pi can be computed (with ever-increasing amount of effort) to almost any number of digits, for navigation of space probes they only need 16. jpl.nasa.gov/edu/news/how-many #PiDay #space #math #astronomy #tech

NASA JPL EducationHow Many Decimals of Pi Do We Really Need? – News | NASA JPL EducationWhile world record holders may have memorized more than 70,000 digits of pi, a JPL engineer explains why you really only need a tiny fraction of that for most calculations – even at NASA.

The debate over definition of planets can become relevant back home. By some definitions, the Moon could be considered a planet. It's a round planetary body. Since it orbits the Earth, it's obviously just a moon. Except it's big enough that as it gets farther away (a few cm each Earth year), there's a point where their center of gravity can go outside the Earth. Any definition that makes the Moon a planet, makes the Earth-Moon system a binary planet. #astronomy

I will share more information soon regarding the site visit to #SURF, a sister underground laboratory to #SNOLAB. I want to share now that the "Deep Talk" lecture I delivered last night at the SURF Visitor Centre was an incredible experience. I was especially excited to be able to personally interact with over a dozen audience members. This included an awesome small-group Q&A session after the formal event.

Watch the lecture online:
