ESA uses a camera in ExoMars Trace Gas Orbiter to capture 3I/ATLAS when it was 18.6 million miles from the Red Planet.
3I/ATLAS likely weighs more than 33 billion tons. The interstellar object hurtling toward the inner solar system, where Earth is located, is much larger than previously thought, astronomers say. A ...
