Astronomers have seen the aftermath of two planetary pile-ups in the same turbulent star system — providing potential insights into how planets form 1. Observations from the early 2000s indicated that ...

This artist’s concept shows what the ultra-hot super-Earth exoplanet TOI-561 b could look like based on observations from NASA’s James Webb Space Telescope and other observatories. Webb data suggests ...

It was almost 100 years ago that Clyde W. Tombaugh discovered Pluto. That was the last planet found until 1992, when humans found another one. But this new planet wasn't in our solar system—it was ...

And why many scientists are freaked out about the first serious for-profit company moving into the solar geoengineering field. Stardust Solutions believes that it can solve climate change—for a price.
