Ribbons and pearls 🎀 Ribbons of gas & dust wrap around the pearly centre of the galaxy NGC 1398.  NGC 1398’s spiral arms do not begin at its very middle, but stem from a straight bar instead. How many spiral galaxies share this feature? Find out: www.eso.org/public/images/potw1801a 🔭

Airborne diseases like Covid are so tricky because transmission depends on so many crazy factors. One person with Covid may not have any detectable viruses in their breath. A single swab from another person may pick up 10 billion viruses! Review: paijournal.com/index.php/pa...

Story time! Six years ago, my first book, The End of Everything (Astrophysically Speaking), came out. It was fun to write! I got to share all my cosmology fun facts and dig deep into all the ways the universe might end. I had SO much fun with it, I thought, "maybe I should write another book?" 1/?

Talk of terraforming Mars before we understand whether it holds clues to the presence of past life is irresponsable. Mars is a window into the geological past, and if there is even the slightest chance that it could contain evidence of ancient biology, we should not be meddling with it.

NASA absorbs but a tiny fraction of the federal budget, yet produces astounding scientific and technological achievements. The current administration wants (once again) to significantly reduce NASA’s budget. That achieves no savings, but it badly damages US space science.

You are here. We've breached 430 ppm CO2. #climatechange
Graph of CO2 concentrations for the past 800,000 years from the Antarctic ice cores, showing current CO2 levels of 430 ppm are far, far higher than any level over this period, which never exceeded 300 ppm. Also shown is the emergence of Homo sapiens around 200,000 years ago -- so CO2 levels are higher than we've ever experienced.

On the left, 24 amber colored debris disks are shown in six rows of four disks. They are ringed structures of various densities and inclinations. On the right, a column of blue disks matches the last column of amber ones, revealing the location of gas in the dusty structures.
