    New paper! Allow me to introduce TARS = Torqued Accelerator using Radiation from the Sun. TARS (yes inspired by Interstellar!) is a rotating light sail that's capable of launching chip sats into interstellar space using only radiation from the Sun, so let's dive into how it works

    The Moon made a guest appearance in our satellite images of the Sun on Feb. 23-24! The Moon appears to reverse course partway through 🌑↩️ — but that’s an effect caused by the relative motion between the Moon and our Solar Dynamics Observatory satellite, which took the images.

    I hope this one holds, my heart can’t take any more spurious claims of life…

    After a year of scientific scrutiny, a rock sample collected by the Perseverance rover has been confirmed to contain a potential biosignature. The sample is the best candidate so far to provide evidence of ancient microbial life on Mars. go.nasa.gov/4n35lVM
    A self-portrait photo of the Perseverance rover on the surface of Mars, taken with a camera on its robotic arm. The six-wheel rover sits in a rocky desert landscape. Its robotic "head" is pointed down to one rock where there is a small hole drilled, along with a small pile of light-colored tailings from the drill.
    A close-up photo of layered rocks. Between two layers, in reddish mudstone, are small, dark spots, slightly lighter at the middle of each spot.

    It’s October which means this is the month JWST will observe Kepler-167e looking for moons - this is the most Jupiter like exoplanet found to transit its star and I can’t wait to see what JWST finds! LET’S GOOOOOOO!!!

    I spoke to two different high flying scientists in other fields this week that thought artist’s impressions of exoplanets were real images. These are literally geniuses in their fields! This really worries me and perhaps we need to re-evaluate this practice.
