`Oumuamua, pronounced oh-MOO-ah-MOO-ah is moving away from the sun faster than expected. The Hubble Space Telescope made the discovery, in cooperation with ground-based telescopes...
The measured gain in Oumuamuas speed is tiny, these astronomers said. Plus, our sun is still trying to drag `Oumuamua back; that is, the suns gravity is still slowing down the object, though not as fast as predicted by celestial mechanics.
Marco Micheli of the European Space Agency led the team that explored several scenarios to explain Oumuamuas faster-than-predicted speed. The most likely explanation is that `Oumuamua is venting material from its surface due to solar heating a behavior known as outgassing. The thrust from this ejected material is thought to provide the small but steady push that is sending `Oumuamua hurtling out of the solar system faster than expected as of June 1, it is traveling about 114,000 kilometers [70,000 miles] per hour.
These scientists explained that, usually, when comets are warmed by the sun they eject dust and gas. This material forms a cloud of material called a coma around them, as well as the characteristic comet tail....
'We did not see any dust, coma or tail, which is unusual. We think that Oumuamua may vent unusually large, coarse dust grains.'
`Oumuamua is a highly mysterious object. Astronomers would love to know where it originated and originally performed the new observations to determine its path more precisely, in hopes they could trace the object back to its parent star system. They werent able to make that backwards trace, and, in fact, the recently-detected gain in speed make Oumuamuas movement more complex, and thus finding its home solar system even more unlikely...
"The true nature of this enigmatic interstellar nomad may remain a mystery."

Gassing? Did you say GASSING??
Well there's here's only one solution of that. Too much freedom for people to screw up the universe with too much gassing. WE NEED MORE GOVERNMENT TO STOP PEOPLE FROM GASSING THE UNIVSERSE! OUR PRIORITY #1 THREATENING PROBLEM!!!
If the singer ever fergits the words to that song, can anybody else tell?
Is it me or does it look like a giant, flying turd?
Its the starship Nancy Pelosi.
Red was it you who sent me those books?
Antimatter.
Berserker...kudos to Frrd Saberhagen. Only reason it didn’t wipe us out was it didn’t detect any intelligent life forms!

When we were little kids, that nonsense tune was so hated by my mom and aunt that every time it was on the radio, one of them changed to a country and western station, because we would immediately start singing it-and if we didn’t stop, we were sent outside to sing in the pasture-another such tune, “Purple People Eater” also caused that reaction from mom and aunt...

That is just the kind of thing that drives adults insane-is there a fenced play area nearby-or if there is a park, can you send them to it? Noise abatement of kids screaming repetitive lyrics is a good thing...
Ah, yes-I remember screaming “one, two, three, four-tell the people what she wore” along with bro and cousins until we were told to take it outside...

Not me!............I still got mine!............
Have you talked to your therapist about #1 and #2 training as a child? ( \justkidding)
A very significant object indeed.
The reason the asteroid is elongated is the same reason interstellar travel is impossible with current and future kinetic technologies. Inter-stellar dust will severely ablate any object traveling between stars. The greater the speed the greater the erosion. At 70k mph this thing has probably been traveling for billions of years.
