Nature’s magnifying glass 🔎
Galaxies in these images might look stretched or warped. That’s due to gravitational lensing, a tool that allows us to peer even further into the universe! https://go.nasa.gov/3KLgN9Y https://pbs.twimg.com/media/G2GJ7ibW0AA2ZMm.jpg

Webb took a look at the Sagittarius B2 molecular cloud, the most massive, and active star-forming region in our galaxy, located only a few hundred light years from our central black hole. Why is it so much more active than the rest of the galactic center? https://go.nasa.gov/46lurcz https://pbs.twim

The 1st exoplanet was found just a few decades ago; now we know they are the rule, not the exception. Celebrate the 6000th confirmed exoplanet, with @NASAJPL's Dr. Eric Mamajek and the Small Steps, Giant Leaps podcast. https://go.nasa.gov/3W1vQPj https://pbs.twimg.com/media/G1eLCs7WcAEoWCG.jpg

Are we alone in the universe?
With Webb’s unprecedented infrared sensitivity, we can detect exoplanet atmospheres and study their chemical compositions in an attempt to answer that question.
But what would it take to be able to say that we found life? We asked a NASA scientist.

Webb is solving mysteries it created. Remember “little red dots?” They seemed too big to exist in the early universe... and maybe theory couldn’t account for them. It turns out they may be a new class of galaxy containing growing supermassive black holes. https://t.co/OXo6TzNgus https://t.co/Y

Like images of broken light, Webb captured these carbon-rich dust shells around a binary star system. Drifting swiftly outwards, they are seeding their surroundings with carbon - one way elements spread across the universe. https://t.co/gjfLhdaP1x https://t.co/rbFjcpKjgm

Webb’s mid-infrared observations show star-forming regions and dust, as well as the large spiral galaxy’s bright nucleus. Near-infrared data (this image) highlights the stars within the colliding galaxies, as well as the translucent bridge of stars being pulled from them both.
