Five galaxies, two nebulae, an exoplanet, and the early universe—JWST’s first images provide a cross section of the science yet to come.
Coronal mass ejections from stars have eluded easy observation, so scientists are looking at what’s left behind.
Astronomers took a direct image of a massive protoplanet embedded in a protoplanetary disk. The system provides strong evidence for an as-yet-unconfirmed theory of planet formation.
Amateur astronomers sifting through NASA’s public data uncovered a long-orbit gas giant that could help scientists understand how these planets form.
Tidally locked planets always present the same face to their host stars. What does this mean for their potential to support life?
Why is our Moon so massive compared with Earth, and how might that configuration happen elsewhere?
The latest road map to U.S. astronomy’s next decade recommends a smaller space telescope, ground-based facilities, and an institutional effort to create an inclusive and equitable field.
The young, growing planet PDS 70 c has enough material swirling around it to make at least three Moon-sized moons.
Some exoplanets orbit their stars from pole to pole instead of across the equator. Why do they do that?
The list of planets in other star systems includes zombies, hot giants, puffballs, and even a few Tatooines. Zowie!
