Did you know ... tucked inside our new exoplanet explorer, Pandora, is a near-infrared detector originally built for @NASAWebb? Pandora will follow up on observations made by Webb and other telescopes of exoplanets' atmospheres and the stars they orbit. go.nasa.gov/4aDT5Wu

Spring into spring with this new image of the Cat's Paw Nebula from NASA's Chandra and @NASAWebb. We expect it to start knocking planets off the counter for sport any minute now. 🐾

Messier 58 … in a different light! Our retired Spitzer telescope revealed the galaxy’s stellar populations. In the representational colors chosen for this infrared view, reddish areas are the likely birthplaces of new stars, while blue light comes from mature stars.

At 5,500 light-years away, Messier 4 is the closest globular cluster to Earth. Globular clusters are spherical groups of stars, held together by gravity. This image spans the wide range of wavelengths that Hubble’s instruments are sensitive to: go.nasa.gov/4uChHZ2

The stars in constellations may look close together from our view on Earth, but they might actually be really far apart in space. This mind-blowing visualization shows the true shape of the Orion constellation in 3D. go.nasa.gov/3PKYVOY

Sometimes, the best science happens on accident. A team using Hubble studied a comet (not even their first-choice target!) and realized they were witnessing it in the act of breaking apart. Find out more about these ultra-rare observations: go.nasa.gov/4lUAdIl

Twinkle twinkle little star ✨ Most known exoplanets are wild and exotic compared to the worlds in our solar system. One of the best ways to find more familiar planets is a mind-bending method called microlensing. Learn how it works: go.nasa.gov/4bg6fe8

Decked out in stars! The Necklace Nebula glows brightly in this Hubble image. These are actually the remains of a dying, Sun-like star, with a ring that consists of dense knots of gas that look like jewels on a necklace. Learn more for #JewelDay: go.nasa.gov/3P6yC5S

Tomorrow is #PiDay – and while we love a good pie, our favorite flavor of pi is of the math variety. 🥧➗ Celebrate with us by solving some of the same problems @NASA scientists and engineers face every day: go.nasa.gov/4lsbEBW

Members of our Fermi mission team bake in their free time! While Fermi studies gamma-rays, not blueberries, it serves us a slice of the universe that includes some of its most extreme environments and events. What can pi(e) can teach us about the cosmos? go.nasa.gov/4lrLMX9

Grab a fork & get ready for Pi Day with some tasty knowledge bites!🍴🥧 What is pi? What makes pi so special? What's pi used for? How does @NASA use pi? The new "What Is Pi?" NASA Knows article for students has answers to these questions & more! nasa.gov/learning-resou…

Galaxies leave clues when they collide. Tails, shells, and faint streams of stars reveal past encounters, and Euclid telescope images are uncovering them in stunning detail. You can help scientists spot these cosmic signatures with Galaxy Zoo: Tidal Tales: go.nasa.gov/4b9QvcA

We're irrationally excited for Pi Day! 🥧 This week's NASA EXPRESS has a plate full of STEM resources to help you celebrate our favorite irrational number on 3.14. Dig in here: conta.cc/4un7pMg

Let's take a closer look 👁️ @NASAHubble teamed up with @ESA's Euclid for a new look at the Cat's Eye Nebula. This is a planetary nebula – so-called not because of any actual planets, but because the nebulae look round like planets from a distance. go.nasa.gov/40lGxOT

Wow, one year in space! 🎉 We can’t wait to see what SPHEREx helps us learn as it continues to map the sky.

This glittering cluster of stars orbits our galaxy's core like a satellite. M92 is a globular cluster – a roughly spherical group of stars held together by their own gravity. Our Milky Way is home to many such clusters, and M92 is one of its brightest: go.nasa.gov/46OR60B

What in the (out of this) world does that mean? We've got a brand new glossary of the universe, in case you also find yourself urgently needing to define "bremsstrahlung." science.nasa.gov/universe/gloss…

Astronomers have spotted an extreme collision between two neutron stars in a very odd place about 4.7 billion light-years from Earth. This result may help answer two different mysteries about stars and intergalactic space. More at: chandra.si.edu/photo/2026/nsm…

Next week, we’re celebrating 100 years of liquid-fueled rocket launches. When the namesake of our center, Robert Goddard, launched the first successful liquid-fueled rocket on March 16, 1926, it began the era of modern spaceflight. go.nasa.gov/4aZU5pp

Stars shine through fusion, which happens when atomic nuclei collide so fast that they stick together, emit energy, and make a new element. Every second, trillions of trillions of fusion events produce energy to balance a star’s own inward gravitational pull. #MondayMotivation
