APOD: 2017 December 17 - The Einstein Cross Gravitational Lens
Explanation: Most galaxies have a single nucleus -- does this galaxy have four? The strange answer leads astronomers to conclude that the nucleus of the surrounding galaxy is not even visible in this image. The central cloverleaf is rather light emitted from a background quasar. via Pocket

Glowing Auras and ‘Black Money’: The Pentagon’s Mysterious U.F.O. Program
For years, the program investigated reports of unidentified flying objects, according to Defense Department officials, interviews with program participants and records obtained by The New York Times. It was run by a military intelligence official, Luis Elizondo, on the fifth floor of the Pentagon’s C Ring, deep within the building’s maze.

Overcoming Bias : Dragon Debris?
Astronomers have been waiting for a while to see such an interstellar visitor, and were puzzled to have not yet seen one. They expected it to look like a comet, except traveling a lot faster than do most comets. Well within roughly a year of a new instrument that could see such things better, we’ve finally seen such a visitor in the last few months. It looked like what we expect in some ways. It is traveling at roughly the speed we’d expect, its size is unremarkable, and its color is roughly what we expect from ancient small space objects. But it is suspiciously weird in several other apparently-unrelated ways.

First, its orbit is weird. Its direction of origin is 6 degrees from sun’s motion vector; only one in 365 random directions are closer. And among the travel paths where we could have seen this object, only one in 100 such paths would have traveled closer to the sun than did this one (source: Turner). But one must apparently invoke very strange and unlikely hypotheses to believe these parameters were anything but random. For now, I won’t go there.

Second, the object itself is weird. It does not have a comet tail, and so has apparently lost most of its volatiles like water. If this is typical, it explains why we haven’t seen objects like this before. The object seems to be very elongated, much more than any other natural object we’ve ever seen in our solar system. And it is rotating very fast, so fast that it would fly apart if it were made out of the typical pile of lightly attached rubble. So at some point it experienced an event so dramatic as to melt away its volatiles, melt it into a solid object, stretch it to an extreme, and set it spinning at an extreme rate. After which it drifted for long enough to acquire the usual color of ancient space objects.

This raises the suspicion that it perhaps encountered a dangerous “dragon” between the starts. Making it “dragon debris.” If the timing of this event were random, we should see roughly one a year in the future, and with new better instruments coming online in a few years we should see them even faster. So within a decade we should learn if this first visitor is very unusual, or if we should worry a lot more about travel dangers between the stars.

When Life Hands You Werewolves - uraneia - Teen Wolf (TV) [Archive of Our Own]
Four hours—that’s how long it takes after the Daedalus II drops off the new contingent of baby scientists and Marines before Rodney starts taking bets on who’ll be the first to get into Derek Hale’s pants.



A month ago John's team rescued a former runner named Derek Hale. He's great to have on offworld missions--he's like a danger magnet; nobody else gets so much as a splinter. But there's just something different about him. John can't quite put his finger on it....

Of All The Planets In All The Galaxies, He Walked Into Mine. - supercalvin - Merlin (TV) [Archive of Our Own]
On Camelot, the base planet of the Albion Intergalactic Alliance, the people have a unique gift where the name of their soulmate appears on their arm. Finding one’s soulmate could be as easy as taking a shuttle over to the next planet or it could take years for destiny to find its way to their side of the galaxy. Ten years ago, Ambassador Arthur Pendragon found out the name on his arm wasn’t from any known language in the galaxy. He hadn’t had much faith in love ever since.

ispace just raised $90 million to launch two private moon missions by 2020
ispace intends to launch its first Moon mission, aptly dubbed ‘Mission 1,’ by the fourth quarter of 2019, and then to do a second by the end of 2020. The first will put its lander into orbit around the Moon for observation, and then the second will see the same lander descend to the Moon’s surface, where it will deploy mapping rovers to conduct further experimentation.
