“Called the Habitable Worlds Observatory (HWO) and targeted for launch around 2040, this would be by far the most ambitious and sophisticated telescope yet built. But its primary goal is almost childishly simple—to hunt for life on 25 Earthlike worlds.” 🔭🪐
In the Search for Life beyond Earth, NASA Dreams Big for a Future Space Telescope
Astronomers are moving ahead in planning NASA’s Habitable Worlds Observatory, a telescope designed to answer the ultimate question: Are we alone in the universe?

#JWSTCycle3 will officially be the most number of proposals received for any one ground- or space-based proposal cycle in the history of astronomy, beating ALMA Cycle 6 by ~100 proposals. Unofficial number is ~1,937 JWST Cycle 3 proposals.

As Project Scientist, I’m proud that JWST is the most in-demand telescope the world has ever seen.
As a fellow proposer, my thoughts and prayers are with the panelists who have to wade through all ~1900 proposals, and with all those great ideas that won’t get time.

Good luck to all who submitted JWST Cycle 3 proposals! Don't forget to take a break, enjoy a glass of wine, and get a good night's sleep!

A good reminder that stars are not actually perfectly uniform disks! Will be interesting to see how the community deals with stellar contamination in future observations of rocky planets around cool dwarfs 🔭
🚨 Attention TRAPPIST-1 fans 🚨
We just published the first JWST spectrum of one of the TRAPPIST-1 planets, so I'm excited to share in this thread what we saw!
Our findings could have important implications for the TRAPPIST-1 planets in the habitable zone.
Read on!

Spent days trying to debug this silly code only to realize that all the synthetic stellar spectra I downloaded are just... empty FITS files for some reason?

The exoplanet, called K2-18 b, could be a Hycean planet – meaning it has a hydrogen-rich atmosphere and an ocean.
