New 3I/ATLAS images from NASA and the ESA suggest the interstellar comet is active as it approaches Earth in December.

The Milky Way is not the calm, flat starry disk many of us learned about in school. Astronomers are now tracking a colossal, ...

Later in December, the 3I/ATLAS interstellar comet will get as close to Earth as it ever will. Here's what to know.

Researchers combined deep learning with high-resolution physics to create the first Milky Way model that tracks over 100 billion stars individually. Their AI learned how gas behaves after supernovae, ...

We cannot see or image the entire Milky Way galaxy, because we are located inside it. From Earth, we can observe only a portion of the galaxy, and when we look up at the dark, clear night sky from a ...

The Milky Way is a rich and complex environment. We see it as a luminous line stretching across the night sky, composed of innumerable stars. But that’s just the visible light. Observing the sky in ...

So it’s confession time: I’ve been lying to you. I’ve said on many occasions that our Milky Way galaxy has a flat disk (like in this column or this one). But it’s not really flat—not even for a ...

This is a human-written story voiced by AI. Got feedback? Take our survey. (See our AI policy here.) A ribbon of red splotches interspersed with blue dots marks the largest, most detailed image of the ...

Astronomers have created a new colorized radio view of the Milky Way's galactic plane. Credit: International Centre for Radio Astronomy Research Astronomers in Australia have created the largest and ...

Our Milky Way is far from calm — it ripples with a colossal wave spanning tens of thousands of light-years, revealed by ESA’s Gaia telescope. This wave, moving through the galaxy’s disc like ripples ...

Johns Hopkins researchers may have identified a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...
