Here’s how it works. The new interstellar object 3I/ATLAS is creating quite the buzz. Here's everything we know so far about this cosmic interloper.

The imprecision in the measurements of claimed interstellar fireballs means it is highly likely they originate in the solar system instead, a new study reports.

The new interstellar comet's official name is 3I/ATLAS. It's officially the third known interstellar object to pass through our solar system, and it poses no threat to Earth.

An "interstellar object" is speeding toward the inner solar system, where Earth is located, astronomers have confirmed.

"Astronomers may have just discovered the third interstellar object passing through the Solar System!" the agency's Operations account shared on Bluesky.

Once identified, an interstellar object is studied in every possible way. Spectroscopy, photometry, and orbital modeling are among the tools used to uncover its secrets.

Udemy’s Rocket Engineering and Interstellar Space Propulsion course provides a considerable amount of information on both topics crammed into a short 2.5-hour program. Although this series of ...
