While making its close pass to the Sun, ʻOumuamua sped up ever so … Scientists have discovered that a comet called 2I/Borisov - only the second interstellar object ever detected passing through the solar system - is surprisingly different in its composition from comets hailing from our celestial neighbourhood. After the initial detections of the comet, JPL’s Scout system automatically flagged the object as possibly being interstellar. By Lucy Berliant.

If the story of our universe is written in the stars, even a tiny fragment traveling a long way for a short visit provides a tremendous opportunity for scientific discovery. Later analysis of the event showed the ejected dust and fragments have a combined mass of about 0.1% of total mass of nucleus, making event a large outburst rather than fragmentation. Tumblr.
