Flush with #JWST’s success, NASA is now planning an optical telescope that would be just as big and have a grand new goal: looking for signs of life on Earth-like planets, perhaps by the early 2040s. scim.ag/19c

Discovery Alert! 📣 A second Earth-sized exoplanet is found hiding in a star’s habitable zone! A year there, one orbit, takes 28 days. It joins three other worlds in the system 100 light-years from Earth. go.nasa.gov/3k8JHns

“The Habitable Worlds Observatory is the highest priority astrophysics space facility of the future!” — Thomas Zurbuchen (Former NASA science chief)

A massive star has a beautiful destiny — on its way to becoming a black hole or neutron star, it’ll shed its outer layers in a brilliant supernova explosion. This week, we’ll be talking about these powerful cosmic events, how we study them, and how we’re connected to them.

The universe is full of wonders. It is a never-ending source of inspiration, reminding us there's always something new to learn, discover, and appreciate. From the intricate dance of the planets to the explosive birth of stars, every moment is a reminder of its beauty.

This Saturday, July 1, @ESA's Euclid spacecraft is scheduled to lift off, shedding light on dark matter and dark energy—two of the biggest modern mysteries about our universe. We'll stream ESA's broadcast live on NASA TV starting at 10:30am ET (1430 UTC): go.nasa.gov/3PE1IaY

Building on the legacies of the Hubble, James Webb and Nancy Grace Roman space telescopes, the Habitable Worlds Observatory would search for and characterize habitable planets beyond our solar system. 🔭 🧪 ☄️ #HWO2025 #HWO25 youtu.be/tfJOkeOHnTw
