The scale of the New Glenn explosion is a reminder of the staggering amount of energy locked up within a rocket, and the extreme engineering it takes to release that energy in a precisely controlled way. 🧪

I'm flat-out amazed that we can monitor the currents of molten metal in Earth's outer core, 2200 kilometers underground--but we can. Lately, part of that flow has reversed direction, for reasons unknown. There's a whole other dynamic world inside the world we see. 🧪🔭 www.esa.int/Applications...

And on the surface of Mars, the Perseverance rover took a blazing, backlit selfie. It took a lot of planning to make this work... 🧪🔭 science.nasa.gov/photojournal...

From 2006-2024, the USMTArray project placed 1,700 sensors on a grid stretching across the U.S. Now we have the results of this exhaustive effort: a 3D map of the electrical architecture of the underlying crust, down to a depth of 60 kilometers. 🧪 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Amazing sequence of images from Artemis II. Look at all the action on and around the Earth: lightning, aurorae, satellites... Image processing via Riccardo Rossi. 🧪🔭

A wave of darkness is spreading across Mars. These images show dramatic changes to the Martian surface over the past 50 years, as volcanic dust blows through an ancient impact basin. 🧪🔭 www.esa.int/Science_Expl...

Comparing old & new images of the Trifid Nebula, we can see how this gas cloud has changed over three decades. Newborn stars are shooting out jets of plasma, stirring the nebula, and the stars are drifting through our galaxy. Cosmic evolution before our eyes! 🔭🧪 esahubble.org/videos/heic2...
