Webb’s latest data gives us the first molecular and chemical profile of a distant world, gas giant WASP-39 b. This bodes well for its ability to probe the atmospheres of small, rocky planets like in the TRAPPIST-1 system: go.nasa.gov/3i3Tlql

lovely data! JWST is an impressive feat. I hope it can get something remotely close to this for earth-like planets!

👇 WASP-39 b is an old friend! In August, Webb showed the first clear evidence of carbon dioxide in a planet outside our solar system. New data from the same planet also shows water, sulfur dioxide, carbon monoxide, sodium and potassium.

Exoplanet spectroscopy is the most impressive thing JWST has done to me, and the thing I highlighted in my presentation to my intro astronomy class about JWST!


We're working with @ESA to plan one of the most ambitious feats ever attempted in space—bringing a Mars sample to Earth. The Mars Sample Return campaign could help answer a question rovers alone cannot: Was there life on Mars?

Here's how we plan to do it: mars.nasa.gov/msr/

You all should know that now, 20 years into teaching astronomy, I open every single class with that day's APOD. Sometimes it is spot-on for what we are studying at the time. At other times it opens doorways into new lines of discussion and thinking. Thank you.


Does anything orbit the Moon?

Yes! A handful of satellites currently orbit the Moon and, now, so does #CAPSTONE! This microwave oven-sized satellite will test a unique halo-shaped orbit to support @NASAArtemis & @NASA_Gateway missions: go.nasa.gov/3URKmHc

The Butterfly Nebula from Hubble
Stars can make beautiful patterns as they age -- sometimes similar to flowers or insects. NGC 6302, the Butterfly Nebula, is a notable example. Though its gaseous wingspan covers over 3 light-years and its estimated surface temperature exceeds 200,000 degrees C, the aging central star of NGC 6302, the featured planetary nebula, has become exceptionally hot.
