See the glittering heart of the Milky Way in this stunning new image
Stephanie Pappas · 2026-06-30 · via Scientific American Content: Global

This brilliant new image, taken by Europe’s Euclid space telescope, offers a preview of the kind of imaging that will be possible with NASA’s upcoming Roman telescope

A field of stars and other objects picked out in gold and purple

This image from Euclid (with color added using ground-based images) zooms in on the center of our Milky Way galaxy. The region gets its golden tone from myriad old, cool stars that have yellowish hues. Stars in this region are heavily crowded, so observing in this direction increases the likelihood of catching microlensing events.

The center of the Milky Way is on fire, lit with pinky purple and golden hues in a stunning new image captured by Euclid, a European Space Agency (ESA) space telescope.

The gold-and-plum glamour offers a glimpse at the heart of our galaxy—an area called the galactic bulge, where some 10 billion stars are packed tight together in an elongated football shape. It’s also a sneak peak at a region of the sky that NASA will explore in depth with the upcoming Nancy Grace Roman Space Telescope, scheduled to launch no earlier than August 30.

Euclid paused its normal sky survey to capture the image, NASA senior research scientist Jason Rhodes said in a statement.

“Adding Euclid’s snapshot to Roman’s future survey will help us map our galaxy better and identify hard-to-find cosmic treasures like isolated black holes and rogue planets more easily,” Rhodes said.

The full image, below, includes about 5 square degrees of the sky—the equivalent of 25 full moons. On the right side, the telescope peers through the galactic plane as if through fog; the dark patches are thick molecular clouds—regions of cold, dense dust and gas where new hydrogen molecules form. Toward the upper left of the image, the galactic plane thins and Euclid gets a clearer view of distant stars.

This image by ESA’s (European Space Agency) Euclid (with color added using ground-based images) provides an earlier snapshot of a region of our galaxy that NASA’s Nancy Grace Roman Space Telescope will repeatedly observe during the upcoming years.

Euclid captured the image in a single day, but the Roman telescope will take a deep look at 1.7 square degrees, or 8.5 full moons’ worth of sky, over five years. Its repeated observations will reveal new planets and other itinerate cosmic objects. Roman will also be on the lookout for microlensing events, which happen when a star, planet, black hole or another massive object aligns with a star from the viewpoint of the telescope. The mass of the giant object gently bends the light from the star, magnifying the view of object.

Among these mystery objects? Massive black holes left behind after the death of the biggest stars. Some of these black holes are so huge that they create long-lasting microlensing events, which is part of why scientists want to observe a small patch of sky over many years, to understand how they change and evolve over time.

Euclid’s broader, less-detailed preview provides a baseline for Roman’s first observations. The ESA’s telescope’s data will also be combined with Roman’s Galactic Plane Survey, which will map a large area of the flat, star-filled plane of the Milky Way in unprecedented detail.

“We’ve shown that these two telescopes can work together to do science that surpasses what either was originally designed for,” Rhodes said. “In doing so, we’ve established a model for future coordinated observations that can unlock far more discoveries than either mission could make alone.”

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
