Meet the James Webb Space Telescope (JWST)—the most powerful space observatory ever launched. A collaboration between NASA, ESA, and CSA, Webb specializes in catching infrared light, making it possible to view galaxies and stars as they were billions of years ago. Since becoming operational in 2022, JWST has already rewritten the textbooks: it’s spotted some of the earliest galaxies, revealed the chemistry of alien worlds’ atmospheres, and explored cosmic events at the edge of time. Why does it matter? In short, Webb isn’t just snapping pretty pictures—it’s decoding how galaxies, stars, and planets first formed. The telescope’s golden mirror and deep-space perch let it peer through cosmic dust that blinds even its legendary predecessor, Hubble. Expect ongoing breakthroughs in everything from the search for habitable planets to unraveling the universe’s expansion. If you’re even a little curious about our origins, JWST is worth watching.

3. Mars Sample Return: Fetching Red Planet Relics

Mars might be the only planet in our neighborhood that’s kept us fascinated for decades. NASA and ESA are teaming up for the Mars Sample Return mission, the first-ever attempt to bring Martian soil and rock samples back to Earth. The journey begins with NASA’s Perseverance rover, which is already roaming Jezero Crater while tucking precious samples into sealed tubes. Upcoming spacecraft will play relay: a lander to grab the samples, a rocket to blast them off Mars, and an orbiter to catch and return them home. Why all this effort? Only on Earth can we truly unlock Mars’ secrets—potential ancient life, underground water, and the processes that shaped both planets. The mission is set for launch later this decade. If all goes well, Martian rocks could be on lab benches in the early 2030s, waiting to reveal whether our red neighbor ever hosted life.

4. Euclid Space Telescope: The Dark Universe Surveyor

If you’ve ever wondered what holds the universe together (and what’s racing it apart), Euclid is the mission to watch. Spearheaded by the European Space Agency, Euclid launched in 2023 to map the mysterious dark matter and dark energy that make up the bulk of our universe. Its advanced instruments are capturing light from billions of galaxies, stretching across over a third of the sky. Scientists hope this grand cosmic survey will help explain how these hidden forces have shaped galaxies and the web of cosmic structure we see today. For the rest of us, Euclid’s work is about unlocking the biggest puzzle pieces of existence. What are dark matter and dark energy, really? How do they influence everything from galaxy clusters to the ultimate fate of the cosmos? Stay tuned—Euclid could provide clues that have eluded astronomers for generations.

5. Vera C. Rubin Observatory: The Living Sky Movie

Imagine a time-lapse movie of the entire night sky—night after night, year after year. That’s what the Vera C. Rubin Observatory, currently under construction in Chile, is set to deliver. Home to the Legacy Survey of Space and Time (LSST), Rubin will scan the southern sky every few nights, capturing everything from fleeting supernovas to lurking asteroids. The aim? To help scientists unravel mysteries surrounding dark matter, dark energy, and even the asteroid threats to our own planet. Rubin’s all-seeing eye will turn the cosmos into a living, breathing tapestry, mapping cosmic events as they unfold. Designed to be a resource for both researchers and everyday stargazers, this observatory is setting the stage for discoveries nobody’s even imagined yet. The sheer scale of its survey is staggering—and it promises to add thrilling new chapters to our cosmic story.

That question is at the heart of the European Space Agency’s JUICE (Jupiter Icy Moons Explorer) mission. Launched in 2023, JUICE is on an eight-year journey to Jupiter, with a particular focus on Ganymede, Europa, and Callisto. These moons aren’t just cold rocks; they’re some of the solar system’s most promising candidates for subsurface oceans and, just possibly, the building blocks for life. JUICE will orbit Ganymede and make close passes by the others, analyzing magnetic fields, surface chemistry, and more. Scientists hope the findings will shed light on whether alien life could thrive in such extreme environments. It’s a long wait until JUICE reaches Jupiter in 2031—but the discoveries could be worth every second.

7. Psyche Mission: The Metal World Explorer

Rocks and ice aren’t the only things floating between Mars and Jupiter—there’s a giant, metal-rich asteroid named Psyche, too. NASA’s Psyche mission is heading right for it, aiming to explore a hunk of exposed planetary core up close. Scheduled to arrive in 2029, the spacecraft will help scientists figure out how planets like ours are born from chaos and collisions. What makes 16 Psyche special? It’s mostly nickel and iron, unlike any other asteroid we’ve studied. By scanning its surface and innards, Psyche could reveal what our own planet’s core looks like—and why some worlds end up rocky, some gassy, and some stuck in between. For geology buffs and daydreamers alike, there’s a certain thrill in finally visiting this mysterious metal world.

8. Tianwen-2: China’s Comet & Asteroid Collector

China’s deep-space ambitions are scaling up fast, and Tianwen-2 is the proof. Following the success of Tianwen-1 (which landed on Mars), the China National Space Administration (CNSA) is aiming for both a near-Earth asteroid and a comet. Scheduled for launch in 2025, Tianwen-2’s mission is two-fold: grab samples from a small, fast-moving asteroid, then swing deeper into space to chase a comet. By analyzing these untouched relics, scientists hope to learn more about the building blocks of the early solar system—and maybe, down the line, protect Earth from cosmic threats. For a world increasingly reliant on global science partnerships, Tianwen-2 is a milestone: it shows just how interconnected our pursuit of the universe has become.

9. SPHEREx: Mapping the Infrared Universe

Think of SPHEREx as the universe’s ultimate mapping project—only instead of roads and cities, it’s charting galaxies, dust, and water across the cosmos. Set for launch in 2025, this NASA infrared telescope will create a detailed 3D map of the entire sky, aiming to reveal secrets about cosmic inflation, the history of galaxy formation, and even the ingredients for planets. What’s unique? SPHEREx will scan in over 100 different colors of infrared light, spotting phenomena invisible to ordinary telescopes. These insights are expected to fuel discoveries about where water (and maybe life) might form in planetary nurseries far from Earth. The results? New clues about the birth and fate of the universe, all delivered in vivid infrared detail.

10. Nancy Grace Roman Space Telescope: The Exoplanet & Dark Energy Hunter
