I study how planets form, both in our Solar System and around other stars. My blog is all about crazy planet-related ideas.

    Wow, when Betelgeuse blows it'll be quite a sight! Awesome plot showing just how bright it'll be and for how long, from a real simulation.

    Science feature Matt Clement & co's work on how the giant planet's instability may explain a lot of features of the inner Solar System, like why Mars is smaller than Earth and why there are few high-inclination asteroids in the inner main belt.

    So, a story I've been working on... The FCC may have wrongly ignored US environmental law in approving SpaceX's Starlink mega constellation (and other satellites). Were it to be sued, it would likely lose. Story below , and thread to follow (1/)

    Great plot to show that humans haven’t lived with an atmosphere like the one we’ve created before. CO2 isn’t just a greenhouse gas. It interacts with our bodies.

    How many "experts" are just the lucky ones who rolled heads a bunch of times?

    This is a great example of how there are so many biases in life. I can only imagine how much grit and determination it would take to toss heads 10 times in a row!

    Check out this sweet tool by & co. to explore how "Earth" would change as a function of the ocean coverage, orbit and other parameters.
