Astronomy / Space Asteroid or Spaceship? - Astronomers check out ‘Oumuamua.

Astronomers to examine interstellar asteroid to see if it is natural or alien technology.

"Astronomers are to use one of the world’s largest telescopes to check a mysterious object that is speeding through the solar system for signs of alien technology.
The Green Bank telescope in West Virginia will listen for radio signals being broadcast from a cigar-shaped body which was first spotted in the solar system in October.

Scientists on the Breakthrough Listen project, which searches for evidence of alien civilisations, said the Green Bank telescope would monitor the object, named ‘Oumuamua, from Wednesday.

Previous work on the body found it to be extremely dark red, absorbing about 96% of light that falls on it. The colour is associated with carbon-based molecules on comets and asteroids.
If, as expected, the telescope fails to pick up any intelligent broadcasts from ‘Oumuamua, the observations are still expected to aid scientists in understanding the body. Other signals detected by the Green Bank telescope could shed light on whether the object is shrouded in a comet-like cloud of gas, and reveal whether it is carrying water and ice through the solar system."

I for one welcome our Hawaiian alien overlords.

At 180x30x30 m a Connie would just fit inside covered in a protective shell

They arrive ! We will become slaves or food

I hope it's a giant hot dog. That would shake things up in theoretical physics.

It's here to talk to our humpback whales.

Sounds like a misinterpretated title a newspaper would use, oh wait...

 

[Arry]

It's name is interesting and its movement is also very interesting. I have heard that it is flying very straight and it is not tumbling. Which is not natural.

Hyperbolic trayectories are somewhat straight when you get far from the focus.

Is it Hyperbolic? I have heard that it is not from our own solar system; possibly, from outside our galaxy.

Agreed the sun must have influenced its path, but I haven't heard anything about that yet.

If I understand well, the trajectories that are traced by objects who surpass the escape velocity (aka they are not going to return, aka not in orbit) are called hyperbolic. Oumuamua (can’t spell right) certantly is on its way out of the Solar System.

There are three hypothesis of its origin.

1 It was an object from the Kuiper Belt or the Oort Cloud which was thrown out of the Solar System by one of the gas giants.

2 It came from another system and passed by ours.

3 It came from the protoplanetary disk of some system in the Milky Way and it has been wandering from system to system for billions of years.

Hypothesis 3 is the most sensible according to some computer simulations.

One thing is for sure, this is the first interstellar object that has been observed inside our system.

Well there don't seem to be any signals coming from it. But if it was an alien spaceship, filled by fossilised insectoids, it would presumably have been dead and powerless for millions of years.

Or billions

Oh dear, got to be deprecating have we? How about this quote:

“Most likely it is of natural origin, but because it is so peculiar, we would like to check if it has any sign of artificial origin, such as radio emissions,” said Avi Loeb, professor of astronomy at Harvard University and an adviser to the Breakthrough Listen project. “If we do detect a signal that appears artificial in origin, we’ll know immediately.”

... Still gonna make a sarky comment?

I don’t trust newspaper at all, they always tend to put bombastic titles that often exaggerate or take quotes out of context.

Yeah, that quote sounds more realistic and yes, I’m in my right to not believe everything the news say and assuming you are an adult I thought you wouldn’t mind.

 

[metatheurgist]

Would be funny if it stopped and reversed course after we pinged it with radio signals.

What ever it is it's certainly strange, I believe it's an alien form of our very own Kepler telescope.

I read that it was sling shotting around the sun and wasn't burning up so what ever it is, it's pretty resilient

It's a giant space turd. Hopefully whatever pinched it off flew the other way....

Comets vaporize because they are made of ice. Oemuamua is an asteroid.
