Doobie the Blunt leaving our Solar System.

An asteroid that visited us from interstellar space is one of the most elongated cosmic objects
known to science, a study has shown.


Discovered on 19 October, the object's speed and trajectory strongly suggested it originated in

a planetary system around another star.

Astronomers have been scrambling to observe the unique space rock, known as

'Oumuamua, before it fades from view.

Their results so far suggest it is at least 10 times longer than it is wide.

That ratio is more extreme than that of any asteroid or comet ever observed in our Solar System.

Using observations from the Very Large Telescope in Chile, Karen Meech, from the Institute for Astronomy

in Honolulu, Hawaii, and colleagues determined that the object was about 400m long,

rapidly rotating and subject to dramatic changes in brightness.

These changes in brightness were the clue to 'Oumuamua's bizarre shape.

"Looking at the asteroid light curve database, there are five objects (out of 20,000) that have light

curves that would suggest a shape up to an axis ratio of about 7-8 to 1," Dr Meech told BBC News.

"Our errors are very small, so we are confident this is really elongated. Also, one has to realise

we don't know where the rotation pole is pointed. We assumed that it was perpendicular

to the line of site. If it were tipped over at all, then there are projection effects and

the 10:1 is a minimum. It could be more elongated!"

But in other respects, 'Oumuamua (pronounced oh MOO-uh MOO-uh), appears to
resemble objects we know from closer to home.


"We also found that it had a reddish colour, similar to objects in the outer Solar System,

and confirmed that it is completely inert, without the faintest hint of dust around it," Dr Meech said.

These properties suggest that 'Oumuamua is dense, comprised of rock and possibly metals,

has no water or ice, and that its surface was reddened due to the effects of irradiation from c

osmic rays over long periods of time.

Although 'Oumuamua formed around another star, scientists think it could have been wandering

through the Milky Way, unattached to any star system, for hundreds of millions of years before

its chance encounter with our Solar System.

"For decades we've theorised that such interstellar objects are out there, and now - for the first time -

we have direct evidence they exist," said Thomas Zurbuchen, associate administrator for

Nasa's science mission directorate in Washington DC.

"This history-making discovery is opening a new window to study formation of solar systems

beyond our own."

If planets form around other stars the same way they did in the Solar System, many objects the

size of 'Oumuamua should get slung out into space.

The interstellar visitor may provide the first evidence of that process.


The Very Large Telescope in Chile was used for observations

As regards how 'Oumuamua became so elongated, Dr Meech explained:

"There has been speculation among various team members about this.

Sometimes very elongated objects are contact binaries... but even so,

the pieces would be longer than most things in the Solar System,

and our analysis shows that it is rotating fast enough that they should not stay together.

"One of our team wondered if, during a planetary system formation, if there

was a large collision between bodies that had molten cores, some material

could get ejected out and then freeze in an elongated shape.

"Another team member was wondering if there could be some process during the ejection

- say if there was a nearby supernova explosion that could be responsible."

The cosmic interloper was discovered by Rob Weryk, a postdoctoral researcher at the

Institute for Astronomy and a co-author of the new study, which is published in Nature journal.

Weryk and fellow Institute for Astronomy researcher Marco Micheli realised

it was going extremely fast (with enough speed to avoid being captured by the Sun's

gravitational pull) and was on a very eccentric trajectory taking it out of our Solar System.

The asteroid's name, 'Oumuamua, means "a messenger from afar arriving first" in Hawaiian.

I wonder what its ̶r̶o̶l̶l̶i̶n̶g̶ rotation rate is.

Oh man I saw that when it debuted. I was six. I had nightmares about that eldritch fire deep inside a papier-maché ice cream cone. This idea was more horrific to me than a phalanx of classical monsters.

The "digitally remastered" ST-TOS has an updated CGI rendition of the planet killer ... that does not capture the pure horror of a badly-made lump of neutronium with a disco-ball Satan Reactor deep inside.

Lol. My mom made me watch Alfred Hitchcock and the Twilight Zone with her so SHE wouldn't get scared when I was 6.

My confession along those lines is watching Alien with my 9-year-old daughter. I was deeply hit by that movie (nightmares, the whole trip) when I was eighteen! She took it in stride and now loves the whole franchise. She draws amazing xenomorphs to this day.

The Doomsday Machine was and remains my absolute favorite ST-TOS episode. Pure perfect space opera, complete with compelling score. And William Windom as the overwrought Commodore Decker? One of the most awesome acting jobs in the history of TV.

I liked the ones they went back in time (to our time) the best.

Thus, I really liked the 4th movie 'The Voyage Home', transparent aluminum was pretty fucking cool.

This guy ^^^ is scamming flat earthers out of cash to fund his backyard trailer park rocket ship lol. He plans to launch Saturday :eyesmoke:

Theories discussed during the interview included NASA being controlled by round-Earth Freemasons and Elon Musk making fake rockets from blimps.

LOL.


Hughes promised the flat-Earth community that he would expose the conspiracy with his steam-powered rocket, which will launch from a heavily modified mobile home - though he acknowledged that he still had much to learn about rocket science.
"This whole tech thing," he said in the June interview. "I'm really behind the eight ball."

LMFAO! Good luck, bro...

This thing gave me a head rush reading it.... Then half way through I realize it was double posted at times... I have a fucking headache now...
I like to catch these T&T out

as most here

TLDR

are looking too fast for an appropriate Gif

no offense intended lol
