3I/ATLAS is carrying ‘key’ ingredients to life, NASA scientist finds

It’s only the third interstellar visitor ever found passing through our Solar System, it refused to sit neatly in the “just another comet” box.…its strange colour shifts, abrupt changes in speed, and the appearance of both a tail and an anti-tail have kept astronomers on alert for months.
