I was preparing for my early morning class back in January 2025 when I received a notice regarding an asteroid called 2024 ...

Just last week, for instance, the Hayden Planetarium at the American Museum of Natural History (AMNH) in New York City ...

Gaia, Europe’s Milky Way–mapping spacecraft, shut down earlier this year. It was arguably the most important—and most ...

Now that Gaia has gone dark, there’s already talk of what comes next. “Do we really need another astrometry mission?” asks Brown, who first began working on Gaia in 1997.

The Vera C. Rubin Observatory stands atop a mountain peak in Chile, from which its telescope and camera will capture extraordinary information about our universe over the next 10 years as part of the ...

Europe compares favourably with the US on the level of space science it delivers, and Esa has sometimes “gone boldly” where even Nasa has not. Now that Esa has turned 50 years old, it’s a good time to ...

The COSMOS-Web team worked to reduce the data, eliminating artifacts, subtracting backgrounds, and improving the astrometry in order to provide accurate photometric and morphological analyses. The ...

The observatory’s mission has revolutionized astrometry, a branch of astronomy that measures the positions, distances, and movements of the stars and other celestial objects.

But a new Yale study offers a road map for finding “twin” planetary systems — showing whether binary stars that orbit each other, and that were born at the same time and place, tend to host similar ...

His strategy for finding new exoplanets to image is highly targeted, guided by evidence of the gravitational pull of a planet from the star’s astrometry. Of the roughly 6,000 exoplanets that have been ...
