NPR's Ari Shapiro talks with astronomer David Jewitt about what we can learn from the third interstellar object to have entered our solar system, a comet-like object known as 3I/ATLAS. A remarkable ...

Last month, Google quietly killed off Google Sky Maps. But there’s still another way to virtually explore most of the solar system a la Google Maps: it’s called Google Maps in Space. Google Maps in ...

Earlier this summer, astronomers discovered something strange whizzing past Jupiter: an interstellar object. Scientists named it 3I/ATLAS. It’s only the third interstellar object ever observed, and it ...
