Listen: The New Horizons spacecraft is about to explore the farthest object ever: Ultima Thule
"This is new horizon spacecraft. He's now will sit up for its New Year's day encounter with the distant Coppa built object. 2014 MU sixty nine ultima Thule among its approach observations over the past three months, the spacecraft's pay taking hundreds of images to measure Ultimas brightness. And how it varies is the object rotates, and those measurements have produced emissions latest mystery about Altima, even those scientists determine back in twenty seventeen that this compability object isn't shit like fear that it's probably very elongated potato-shaped, maybe even to objects. That's a mystery and itself, they haven't seen the repeated possessions in brightness that that expect a fine from a rotating object of that shape periodic variations in brightness during every rotation produce. What scientists call a light curve, and you horizons principal investigator Allen stern from the southwest research institute says ultima Thule slight curve is tiny and a real puzzle. Now one possible. Explanation for this is that the orientation of automobiles rotational axis might be aimed are the directly at all very close to the new horizon spacecraft. So the probes actually seeing this copper about object and on, but it's also possible that ultimately surrounded by a thick cloud of dust. And that does could be obscuring the light curve in much the same way a comet's coma. Often overwhelms the light reflected by the central nucleus. The problem is if this was a come coming from ultimate fool. It would require a hate souls, and the sounds too far away to provide that and even more bizarre scenario is one in which ultimately will surrounded by lots and lots of tiny, tumbling moons. If h moon has it's own light curve, then together they could create a jumbled superposition of light curves that make it look to new horizons like ultima Thule has a really tiny like of the problem with that idea is that there is no parallel to any other body in the solar system. Placing it into the unlikely basket the real answer to this mystery will only become clearer. When you horizon Switzer the ultimate Phil taking its high resolution images on year's"
