Reply to If you could instantaneously place a space telescope at any desired distance (LYs), from any planet/galaxy etc., where would it be and what would you be documenting? And for what purpose? by kennyarsen

On Elock-32b-clum203b facing earth, zoomed in on the Pantera cover band photo that www.news.com.au used in a story about Pantera’s Germany gigs being cancelled earlier today, instead of using photos of the actual band or it’s current line-up that is touring.

That's wholly dependent on the objects' orbit around the host body (Elliptical orbits will produce more tidal heating, and the closer the periapsis to the host the stronger the heating), whether it's locked/resonant locked or not (a 1:1 tidal lock produces little heating, a 3:2 spin-orbit resonance requires an elliptical orbit but also doesnt produce much heating; see Mercury), and whether there's other bodies of sufficient mass orbiting the host to allow for orbital resonances.

If the EarthMoon has a nearly circular orbit, is tidally locked, and has no other sibling bodies orbiting the host, it's going to get fuck-all for heating. On the otherhand, throwing in a bunch of secondary bodies of sufficient mass in resonant/near resonant orbits will get ample heating. This is how Io and Europa get their energy to drive their activity. Enceladus around Saturn is in a 2:1 resonance with Dione, and the resultant tidal energy drives the southern polar jets.

This was my answer. Technically halfway between the milky way and Andromeda is within both the milky way and Andromeda Galaxy at the same time, and we have recently discovered stars in orbit in this area. It would be a very interesting spot to observe!

Oh man you guys aren't thinking creative enough.

Solar Gravitational Lens Telescope. use the Sun itself to get some amazing data. Either our own star or put it around some other massive star or even a black hole, get some crazy data.

Reply to comment by Brief-Ad3374 in NASA's Annual Day of Remembrance today, Jan. 26, honors the astronauts who died during the Apollo 1 fire and the Challenger and Columbia space shuttle disasters. by clayt6

Absolutely, should be a day of public shame for nasa. the way they attempted cover ups and then treated the deceased astronauts(and their families) was reprehensible.

For all nasa has done it is hard to have pride in that organization once you read all that went down in these cases.
