In a radio interview about the TRAPPIST-1 system, a Belgian astronomer on the discovery team was asked if the planets had been named yet. He said no, and that his suggestion they be named after brands of Belgian beer was, unfortunately, not likely to be followed.

 

Too bad. An extravagant multi-planet system named for beers has an almost Jack Vance feel to it, like the Rigel Concourse from his "Demon Princes" novels. The Beer Worlds!

ADDENDUM: A beer aficionado friend of mine explained the astronomer's joke more fully, along with supplying suitable names for the planets:

 

> Westmalle, Rochefort, Westvleteran, Chimay, Orval, Achel, and Koningshoeven.
>
> These are all Trappist beers. These planets are making me thirsty!

 

I guess many Belgian beers were originally brewed by Trappist monks, so it's all a play on the mission's name.

The March, 2017 issue of Scientific American features an article about the Breakthrough Starshot proposal to send micro-probes to Alpha Centauri.

Well, if it's ultra-cool it won't return our calls, anyway.


Still, 7 earth like planets around one star 40LY away. I predict that we will have over a million identified exoplanets by the end of the century.

 

But how many will we have invaded?


...and that's when the destruction began.

Seeing them is easy, but the commute is a killer.

There's a NASA proposal to restore Mars' atmosphere, by putting up a satellite with a strong magnetic field to repel solar winds. Neat. When we recreate the dinosaurs we can put them there.
ROOMMATE WANTED in Northeast DC, beginning January 1st. If interested, please PM me.

Genetic Science experiment with Deadman Asteroid? Nice to finally see some concerns for safety.

The April, 2017 issue of Scientific American has an article on Tidal Disruption Events (TDEs) -- when a star falls into the supermassive black hole at the center of a galaxy. These are emerging as an important way to determine the mass and spin of such distant black holes, and maybe other properties as well. (The basic difficulty in studying black holes being that you can only observe them through their interaction with other things.)

 

The article noted in passing that TDEs may also become useful for studying the internal composition and structure of the infalling stars, since the insides get smeared out and separated from the outsides. It is even possible that sufficiently sensitive and powerful telescopes might observe the planets of infalling stars as they too are disrupted, merge with the accretion disk and ultimately spiral into the black hole.
