Good straightforward article on the interstellar comet.

Very big news: A comet discovered just a couple of weeks ago appears to be one the most rare and exciting of all cosmic beasts: An interstellar visitor — literally an object coming from interstellar space, from an alien star!
The object is called C/2019 Q4 (Borisov) — though that name may change, as I'll get to in a sec — and it was discovered in observations taken on August 30, 2019 at the Crimean Astrophysical Observatory by Gennady Borisov using a custom 0.65-meter telescope. It didn't take long to find the object had an, um, unusual orbit, and follow-up observations taken a few days later using a much larger telescope confirmed its strange nature. There have now been quite a few observations, and although many mysteries remain, we can be pretty sure this thing came from Out There.
To be probably too careful here, I want to say that there is a slim chance it's not from outside our solar system, but honestly at this point I wouldn’t put much money on that. As more observations come in it looks more and more like this is the real deal.

It is hardly a surprise this comet is found some months after that other interstellar visitor - Oumuamuah (the hell how it writes). This mean that our detectors are getting better and better.

As for the exoplanet... well, we are getting closer and closer... prepare yourself for the greatest cultural shock in human history... 10 years, 15 years...

Astronomers are celebrating new images of the interstellar comet that was discovered zipping through our solar system last month.

A new image of comet C/2019 Q4, taken by the Nordic Optical Telescope and shared with Popular Mechanics, provides a new perspective on the interstellar visitor.

In the next few months, C/2019 Q4 could reveal insight into the formation of distant star systems and, possibly, the universe.
