Mathematicians find one pi formula to rule them all A mixture of AI and algorithms uncovered a hidden structure spanning 2,000 years of equations for pi

Happy π Day! To prep, feast on this article on a brand new discovery for the ancient constant. My latest slice for SciAm! It's irrationally enjoyable... 🥧

Attending #LPSC2026? And do you like board games? I’ll be hosting 1-2 game nights. Monday night I’m trying to get 2 more for SETI (the current best space game out there… does take 3 hrs). And Wednesday night. Message me/ comment if interested.

SuperCam : 5 ans de coopération scientifique et technique pour percer les secrets de Mars | CNES Depuis 5 ans, SuperCam, instrument français du rover Perseverance, étudie la géologie et l’atmosphère de Mars. Une quête collective, racontée ici par deux scientifiques et une ingénieure du CNES.

Un article super intéressant sur les activités de l'instrument SuperCam de Perseverance, qui illustre la collaboration entre l'IRAP et le @cnes.fr, avec les interviews de Agnès Cousin, Olivier Gasnault et Magali Bouyssou.

A large outcrop of rock, overshadowed by part of the rover, exhibits a fresh abrasion on one of its dark uneven sloping surfaces - light toned debris dust has fallen across the rock surface beneath it.

A cover of the Nature journal, dated 12 March 2026. Cover image features an artist's view of a supernova model with a magnetar, or highly magnetized neutron star, at its center, surrounded by a wobbling an spinning disk of accreting matter. In detail, superluminous supernovae are at least ten times brighter than their regular counterparts, but astronomers have remained in the dark about what exactly powers these phenomena. In this week’s issue, Joseph Farah and colleagues confirm that magnetars - highly magnetized neutron stars formed by a supernova - are a driving force of these explosions. The researchers analysed light emitted by a superluminous supernova more than a billion light years from Earth. Using a new model of the supernova, they determined that a rapidly rotating magnetar is at the centre of the explosion, and that the massive amounts of energy deposited into the supernova ejecta is the cause of the superluminous glow. A disk of accreting matter spins around the magnetar (as pictured on the cover) and this disk ‘wobbles’ owing to an effect predicted by Einstein’s general theory of relativity. This results in the amount of energy being deposited fluctuating, accounting for the unique rise and fall in the supernova’s brightness observed from Earth. Main title reads "Power Sourced".

Bridging the 1970s: Lunar Viking (1970) The story of spaceflight told through missions and programs that did not happen - that is, the great majority of them.

I have a question for all you Mars rover aficionados - could the Curiosity and Perseverance rovers operate on the Moon?

This study I wrote about assumed that the Viking Mars lander could be used at the Moon, which got me to thinking.

Nebulous blue gas surrounded by red gas against a sea of stars. Looks a bit like a galactic flower.
