Oumuamua: SETI is a common asteroid study with a thundle



The first interim visitor does not have a & # 39; Try to call us, or home – or anywhere else – SETI is named. But that has done a lot to make clear what is the secret thing.

Oumuamua – Hawaiian wants a messenger – like anything we've ever seen.

It may have been an asteroid. He could be a command. Maybe it's … something else. Ever since he saw humanity last year, Oumuamua gave – something that goes through something to do; Spinning through our Solar System – which gives us the descendants.

The Allen Telegascop (ATA) SETI Institute used to monitor the thing for several weeks after it was first identified, and set about 274 million kilometers away.

After playing a sound to & # 39; Background, the telescope showed a powerful radio telescope power that Oumuamua had not split out.

So the chances are that it is an inter-state room test to take action. No, whether to be an active person.

Oumuamua

He ishave heavily: a & # 39; fly through our Solar System on an open parabola, confirming the need to come from a deep inter-state place.

It's pretty beautiful: so some climbers have probably thought it could be a wind power.

He drinks: it's only very small, but something has something; gives a little page to Oumuamua. It could be & # 39; overshadowing But at the same time his tail is seen to have a tail.

It has a strange form. Based on extrasioning spraying, radios have gone out, Oumuamua must be long and thin. Asteroids and comics are not just like that.

So SETI is interested.

As part of the Breakthrough Listen campaign, agree SETI if & # 39; Oumuamua is a display device – and radio shows may have been brought on either side, or that they were just sorted out to work in a mechanical way.

Not fortunate. No inter-state broadcasting was heard. No red radar was found.

"We were looking for a signal to prove that this is something that incorporates some technology – it was a real inventory," said researcher Gerry Harp. "We did not find such energies, despite a healthy survey. Although our ideas do not produce a non-natural base for Oumuamua, they are important data to reach his / her / her / her / her / her / her / hers.

But we have the opportunities to learn anything else from our first inter-national visitor. Racing is away – back to a deep place – at around 95,000km / h.

But SETI is still going to hope.

He has an interest in other strange things in our Solar System.

"It's been thinking that some of the last ones could be inter-state exams, and radio ideas offer a way to address their self- This imaginative, but it is not impossible, a comment, "he says in a statement.

Is there life in the globe?

OUMUAMUA MYSTERY

NASA published last month to investigate & # 39; out, when he spipped her spitzer infrared spitzer telescope to Oumuamua in November last year, he saw … it was not.

Which, in itself, tells.

Comets

"Oumuamua was too long for Spitzer to find out when he looked more than two months after the closest way to Earth in early September," said NASA. "However, the" uncovering "is a new ending on how big it can be."

It also shows that Oumuama was unusual.

When Oumuamua first saw her passing her & # 39; sun, the tail – like woods – was not caused by ice to go into space.

ACCOUNTS: Does our first inter-visitor visitor become a foreign place to prove?

However, since then, the inter-state thing has been designated to change a small course – and accelerate something small – similar to woods, under sunscreen heated ice ideas to let it go.

Is it a proven place of proof, how does one Harvard scholar (himself propose to probe to Proxima nearby) his recommendation?

Is it not something else – a weird compassion of interstate material that looks like anything we've ever seen?

New PROTECTIONS

The new study is now suggesting that & # 39; Oumuamua is up to 10 times larger than the comics that are usually found in our solar system.

That is amazing.

"Oumuamua has been traveling through an inter-state place for millions of years, far from any star that can upgrade it," said the NASA report. "But the surface may have been restored through this sort of time when it made a nice approach to our Sun, just over five weeks before it was discovered. "

It was produced such a & # 39; break & spell & & # 39; screaming on the surface of Oumuamua, and which could be able to harden new immovable ice repositories instead.

And this clarity may have made Oumuama more than it was to a flexible telescope, such as Hubble.

NASA now believes that it is less than half of its original estimates, and is somewhere between 400m and 100m long.

"Usually, if we get a measure from a comet that's so weird, we'll go back and measure it again so we can understand what we see," said Davide Farnocchia at NASA. "But this one is away forever; maybe we understand how much we know as ever."

NASA decides that the gas jets are offset offsets & # 39; Oumuamua has given some progress in the distance, as was suggested earlier this year.

The ideas of Telescope Spitzer Spitzer – yet you can not see & # 39; Oumuamua – shows that it needs to be small enough for such acceleration.

"That decision was up to Oumuamua to be almost less than a solar system comets," said NASA.

& # 39; Oumuamua was first discovered by Pan-STARRS 1 telescope at Hawaii University on Haleakala, Hawaii, last October. It is a Hawaiian word that means "a visitor from coming first".

Hubble was watching. So a number of telescope based on the ground. They saw that it had sunlight – but that it was really changing. This was Oumuamua's proposal to be long, and less than 800m long.

OPEN, OR NOT?

He does not want to prove – or deny – recent controversial applications by two professors of Harvard, Shmuel Bialy and Abraham Loeb.

"It is a clearer situation that Oumuamua may have been a completely operational confirmation that was terminated to the Earth side by a foreign civilization," they wrote.

ACCOUNTS: US weapons want a space engine & is impossible & # 39;

But this was a real vitality, based on the distance and the unusual course of the object.

However, it could be so reflective, however, to fuel fuel & idea & # 39; affirmation of community space & Light sails work in a similar way to the wind-shaft – which uses the energy of solar winds by means of " appear in another way to create shapes.

Starshot

And the smaller size estimated by Spitzer's review is also that advocates will be invited to argue room: Harvard's own professors are advocating & # 39; star spiders & # 39; – small sights of sun sailing – will be launched at nearby star.

The Professor of Curtin's radio rhetoric, Steven Tingay, says that the change among his scientists related to this idea has been remarkable.

"On social media, scientists have done quite personalized attacks – especially Loeb – for mediation for this work," he writes in a & # 39; Conversation.

"A scientist has not claimed a statement." Oumuamua is a stranger in this debate – they have just raised questions and investigating answers. There is no reason to spoil from an appropriate discussion about external information searching or personal audit of colleagues … If other bids are made, strong and strong evidence is required – not a decision based on a few ideas that are difficult to explain, and more ideas. "

Find life

NASA's views make it more likely that Oumuamua is a dumb inter-state signal that was expelled by thousands of thousands of years in an inter-state. Once it's pretty close to its & # 39; sunshine to boil this, there was a sculptured cross – changing its features in a way that changed its street.

But we do not always know, however.

There is no way to look good at the enigma that's going on; to return quickly.

But perhaps we have not yet heard an end.

"Everything in Oumuamua (almost not done by others, in my opinion), is an interesting thing and gives a lot of scientific questions interesting that will encourage further investigations and ideas, "Professor Tingay says.
