✨You know together we're glowin' / Gonna be, gonna be golden ✨ @NASAHubble captured an image of a newly-forming star in the constellation Orion, also known as the HUNTR/X – er, we mean "the hunter." Intense stellar winds from this developing star, shining bright to the left of the image, have carved out a cavity in the surrounding cloud of gas and dust. It’s part of the Orion Molecular Cloud complex, which lies within the constellation's “sword” roughly 1,300 light-years from Earth. Image description: A single developing star with four beams of light emanating from it stands out to the top left of this golden-tinted image. A cloud of gas and dust swirls around it. The cloud clears to the top right and bottom left of the image, revealing hundreds of background stars. Credits: NASA, ESA, and T.

Must be a full moon, feels like one of those nights 🎵⁣ If you’re in search of something to do this weekend, look up! The next full moon will be on Sunday, Feb. 1. What you see on the Moon with just your eyes will vary depending on your eyesight. Give yourself plenty of time for your eyes to adjust and look carefully.⁣ Without binoculars, you’ll be able to see a few landmarks like Aristarchus Plateau, Mare Serenitatis (the “Sea of Serenity,” where the Apollo 17 astronauts landed), and Mare Fecunditatis. Using binoculars or a telescope will reveal more details, like cliffs. Visit go.nasa.gov/moonguide to learn more about them!⁣ Image description: The Moon is a big, round ball with a beige tint to its actual gray color. The Moon is light gray with large, darker gray areas.⁣ Credit: NASA/Bill Ingalls⁣ #NASA #Moon #Space #Skywatching #Astrophotography
Red light, green light 🚦 On Jan. 19, 2026, NASA astronaut Chris Williams snapped this photo of an aurora borealis as the @ISS passed over Europe. The Earth was shadowed by night, but aglow with more than just city lights. An aurora occurs when energized particles in space collide with particles in Earth’s atmosphere, resulting in a bright and colorful light show. When it happens in the Northern Hemisphere, it’s called an aurora borealis, or the northern lights. In the Southern Hemisphere, it’s called an aurora australis, or southern lights. These light shows are typically found close to Earth’s northern and southern poles. But when Earth is hit with a huge flow of energized particles, like during a solar storm, auroras can stretch farther toward the equator. Image description: An image of shadowed Earth, lit up by the city lights of Europe and an aurora around its rim. The city lights appear as dense dots of warm light that outline the land’s shape. The aurora appears as two bands of light—one green and one red—outlining the planet. Credit: NASA/Chris Williams #NASA #ISS #Astrophotography #RedGreen
Who would you take with you on a trip around the Moon? As we prepare to send our Artemis II astronauts around the Moon, we’d love to know who’s on your #NASAMoonCrew. Who is packing the snacks? Who is making the lunar playlist? Who is driving?! Share your photos, art, videos—anything depicting your crew—with the world! Do a photoshoot decked out in your favorite NASA gear. Write a song about what your favorite TV show characters would be like on the journey. Make a stop motion animation of you and your besties flying around the Moon. Use the hashtag #NASAMoonCrew for a chance to be featured on our social accounts or on the Artemis II launch broadcast. Check the link in our bio for more.

Say hello to Phobos! In this photo snapped by @NASAHubble, we were able to catch the tiny Martian moon right next to its planet, illustrating their massive size difference. Mars is about half the size of Earth, with a diameter of around 4,200 miles. Phobos is minuscule in comparison, however, measuring 17 miles in diameter at its widest point. Unfortunately for this little friend of Mars, you cannot spell “friend” without “end.” Like Icarus flying too close to the Sun, Phobos is moving a little too close to the Red Planet, approaching at a rate of six feet every hundred years. This means that it is set to crash into Mars in 50 million years, or break up into a ring like the ones that Saturn and Uranus have. But no matter what happens, Mars will not be doomed to loneliness. Mars has another moon in addition to Phobos, named Deimos. Both are thought to be captured asteroids and have a lumpy, irregular shape—unlike larger, spherical moons. Out of the two tiny Martian moons, Phobos is the largest, with Deimos only measuring nine miles at its widest diameter. Image description: An image of Mars next to its tiny moon against the backdrop of black space. The brown and red body of Mars dominates the right half of the photo, cut off so that only about a quarter of the full planet is visible. The single star-like dot next to Mars is Phobos.

Welcome to my crib 🌟 In this image taken by @NASAHubble, you’re looking at a high-mass star-forming region called Cepheus A. It’s located about 2,400 light-years away in the constellation Cepheus—hence its name. It’s home to a collection of baby stars and a large protostar, which is an actively-forming star. Cepheus A’s protostar is responsible for half of the region’s brightness. Image description: A dramatic cloud in space, with high contrast between the dark zones of dense, light-blocking dust and the vivid, colorful light shining out from the openings. The light glows in orange, lavender, and deep, steely blue. The dust is studded with four-pointed stars of variable color and brightness. Credit: NASA, ESA, and R.

Catch a glimpse of this celestial meetup! On Jan. 23, the Moon and Saturn will form a conjunction in the night sky. This means they’ll look close together despite being far apart in space. This conjunction will give us an opportunity to easily spot Saturn in the sky. To spot Saturn, look to the western night sky on the 23rd, just below the Moon. Happy skywatching!

Every January, we pause to honor members of the NASA family lost in our space exploration program – including the crews of Apollo 1, Challenger STS-51L, and Columbia STS-107 – by celebrating their lives, their bravery, and their contributions to human spaceflight.⁣ Safety is a key value at NASA. It’s the cornerstone that we build mission success on. As we push forward to the Moon and Mars, continue missions to the International Space Station, and work with commercial companies and international partners, it is vital that we always remember and implement the lessons of the past in our preparations.⁣ Image descriptions:⁣ 1.

NASA’s @250_freedom Commemorative Patch has officially launched! 🇺🇸🚀 Honoring America’s 250th anniversary, the Artemis II crew will wear this patch during their historic launch. The theme, “Rocket’s Red Glare,” draws inspiration from the iconic lyric in The Star-Spangled Banner symbolizing perseverance, innovation, and the enduring spirit of exploration that defines our nation.
Galactic upcycling ♻️ @NASAWebb captured a new close-up of an old favorite, the Helix Nebula. We've seen this region before with telescopes like @NASAHubble and the retired Spitzer Space Telescope, but Webb zooms into this dying star with a deeper, more detailed view. The first image shows Webb's view of the blistering winds of hot gas from a dying star crashing into colder shells of dust and gas that were shed earlier in the star's life. Like oil trying to push through water, the differences in density (and speed) of the material give the nebula this incredible structure. Leftover cores of dying Sun-like stars like this one are called white dwarfs. While out of the frame, this white dwarf lies right at the heart of the nebula. Its radiation lights up the surrounding gas, creating an environment for complex molecules to form within dust clouds. This interaction is the catalyst for the raw material from which new planets may one day form in other star systems. It reminds us how stars recycle their material back into the cosmos. Slide two shows a 2003 composite image of the planetary nebula blending Hubble images with the wide view of the Mosaic Camera on the National Science Foundation's 0.9-meter telescope at Kitt Peak National Observatory. Slide three shows the retired Spitzer Space Telescope's infrared snapshot from 2007. Image descriptions: 1.
