1I/2017 U1 `Oumuamua

ESO:

For the first time ever astronomers have studied an asteroid that has entered the Solar System from interstellar space.

!!!!!!

This created a unique problem for the naming of this object.

The IAU also created a new class of objects for interstellar asteroids, with this object being the first to receive this designation.

When these types of things break I like to allow a little bit of time for more research, observations, and perspectives to be published. I’ve been soaking in everything I can about this object over the last few days. The entire thing is so so cool.

What a year it has been in astronomical observations!

ESO observes kilonovae

European Southern Observatory:

ESO’s fleet of telescopes in Chile have detected the first visible counterpart to a gravitational wave source. These historic observations suggest that this unique object is the result of the merger of two neutron stars. The cataclysmic aftermaths of this kind of merger — long-predicted events called kilonovae — disperse heavy elements such as gold and platinum throughout the Universe. This discovery, published in several papers in the journal Nature and elsewhere, also provides the strongest evidence yet that short-duration gamma-ray bursts are caused by mergers of neutron stars.

Just two neutron stars makin’ it rain.

What an incredible observation. Well done ESO.

Update: Here is the timelapse.
