NASA/Don Pettit NASA astronaut Don Pettit used a camera with low light and long duration settings to capture this Jan. 29, 2025, image of the Milky Way appearing beyond Earth’s horizon. At the time, the International Space Station was orbiting 265 miles above the Pacific Ocean off the coast of Chile just before sunrise.
Pettit is part of the Expedition 72 crew, along with NASA astronauts Suni Williams, Butch Wilmore, and Nick Hague. The orbital residents are exploring a variety of space phenomena to benefit humans on and off the Earth including pharmaceutical manufacturing, advanced life support systems, genetic sequencing in microgravity, and more.

The European Space Agency’s Milky Way-mapper Gaia has completed the sky-scanning phase of its mission, racking up more than three trillion observations of about two billion stars and other objects over the last decade to revolutionise the view of our home galaxy and cosmic neighbourhood.

Video: 00:02:05 This is a new artist’s animation of our galaxy, the Milky Way, based on data from ESA’s Gaia space telescope.
Gaia has changed our impression of the Milky Way. Even seemingly simple ideas about the nature of our galaxy’s central bar and the spiral arms have been overturned. Gaia has shown us that it has more than two spiral arms and that they are less prominent than we previously thought. In addition, Gaia has shown that its central bar is more inclined with respect to the Sun.
No spacecraft can travel beyond our galaxy, so we can’t take a selfie, but Gaia is giving us the best insight yet of what our home galaxy looks like. Once all of Gaia’s observations collected over the past decade are made available in two upcoming data releases, we can expect an even sharper view of the Milky Way.
