INTERSTELLAR ‘OUMUAMUA’ (1i-2017-U1)

'Oumuamua: A Mysterious Interstellar Interloper Dr. Amaya Moro-Martin, Space Telescope Science Institute During the formation of our solar system, a tremendous number of asteroids, comets, and planetesimals were ejected into interstellar space by gravitational encounters. If extrasolar planetary systems, which are now known to be quite common, experienced a similar development, then our galaxy should be teeming with these expelled objects. Astronomers were perplexed that none had been found passing through our solar system. Then, in 2017, the discovery of ‘Oumuamua transformed the situation from puzzlement to bewilderment. Observations with a wide range of telescopes followed the brightness and trajectory of this first interstellar interloper but left important questions about its origin and composition unanswered. Further, what process was responsible for the non-gravitational acceleration found in its unbound orbit? This cosmic visitor will not return to provide explanations. Thus, the intriguing inquiries ‘Oumuamua left behind will remain as we seek out and study other guests from beyond our solar system. Host: Dr. Frank Summers, Space Telescope Science Institute Recorded live on Tuesday, July 7, 2020. More information: www.stsci.edu/public-lectures

The European Southern Observatory used many of its telescopes to study 1I/'Oumuamua and 2I/Borisov, the first interstellar objects humanity has discovered flying through our solar system. -- Why Was 'Oumuamua So Weird?

By using ESO telescopes and other facilities, astronomers often glance into far-away planetary systems to gather clues about them. But, on rare occasions, scientists get to study these distant systems by looking much closer to home, when visitors from other corners of our galaxy drop by our Solar System.

Where is Oumuamua? A new interview with Darryl Seligman from the astronomy department at Yale with an update on the subject of Oumuamua. We detail his findings that the interstellar object Oumuamua is an extremely strange object with unknown origins, though there has been some progress in determining it’s shape and composition. Also, ESO has decided on a comet intercept mission that will target interstellar object over the next decade.

A Strange Object Found In Space ► Subscribe: https://goo.gl/r5jd1F Astronomers have cataloged eight planets, 6,500 comets and more than 525,000 asteroids, but a mysterious thing happened on October 19, 2017 in Hawaii that grabbed the attention of millions of people and scientists around the world because what they discovered was unlike anything seen before. The first ever recorded interstellar object was found to have entered our solar system somewhere from deep space. It was given the name Oumuamua, named after the Hawaiian term for ‘scout’ or ‘messenger from afar’, and its path showed that it was not gravitationally bound to our own solar system. But what was this strange object, and where did it come from? #space #objects #strangespace

Was Oumuamua an alien spaceship? No. Here’s what it is. New videos DAILY: https://bigth.ink Join Big Think Edge for exclusive video lessons from top thinkers and doers: https://bigth.ink/Edge ---------------------------------------------------------------------------------- Oumuamua, a quarter-mile long asteroid tumbling through space, is Hawaiian for "scout", or "the first of many".It was given this name because it came from another solar system. Some claimed 'Oumuamua was an alien technology, but there's no actual evidence for that. ---------------------------------------------------------------------------------- MICHELLE THALLER: Dr. Michelle Thaller is an astronomer who studies binary stars and the life cycles of stars. She is Assistant Director of Science Communication at NASA. She went to college at Harvard University, completed a post-doctoral research fellowship at the California Institute of Technology (Caltech) in Pasadena, Calif. then started working for the Jet Propulsion Laboratory's (JPL) Spitzer Space Telescope.

This is really true. We discovered a really interesting type of asteroid-- a rock flying through space. And it was something that we'd never seen before. We knew for a fact that this rock could not have come from our solar system. It was going so fast that it had enough velocity to escape the Sun's gravity entirely. In fact, when it went past the Sun, in late 2017, at top speed it was going 196,000 miles an hour. That's by far enough velocity to completely go away from the Sun's gravity and go all the way out into interstellar space. Now, this object was discovered by a program called Pan-STARRS, which is run by the University of Hawaii. It's a telescope that looks for near-Earth objects, as partially funded by NASA. NASA actually scans the sky, looking for asteroids. We want to make sure the earth is never under any threat from an asteroid that might be coming near us. We're also very interested scientifically in where the asteroids are and how they formed. It was named 'Oumuamua. And that's the Hawaiian word for scout-- the first arriving of many. And this was the first thing we'd ever seen from another star. So the idea of being the first, being a scout was a wonderful and poetic thing to name this thing. To give you a sense of how unusual 'Oumuamua is, we know that it's a rock like an asteroid in our solar system, but it has a completely different shape. We've never seen anything in our solar system that looks like this. It's about a quarter of a mile long, and it's actually elongated like a cigar. It's 10 times as long as it is wide, and we know that it's tumbling through space. It actually tumbles and rotates around its axis about once every seven hours. Now, that means it's tumbling pretty fast. So in order to stay together and not just fly apart, it must be pretty rigid, made of rock or even something metallic. So it's a hard object, elongated, tumbling through space at incredible speeds. There also is something mysterious that happened as this object left our solar system. It's actually now around the orbit of Jupiter. And that is it changed its trajectory just a tiny little bit. It actually sped up a tiny little bit as it went away from the Sun. And that wasn't expected. We've seen that sort of behavior from things like comets. That when comets have a bit of gas or something trapped under the surface and the Sun warms it up, you can get a little jet that comes off the comet-- a little jet of gas that changes its velocity. We didn't think that 'Oumuamua had any of those volatiles, those gases on it, but apparently it did. As it went away from the Sun, it changed its trajectory just a little bit. It also has attracted some attention because some people have wondered, could this be a technology? Could this be a spaceship or part of a spaceship? Or some people have talked about a lightsail-- something that actually can use stellar winds to accelerate and move between the stars. I'm always very concerned when somebody suggests a natural object like 'Oumuamua might be an alien spaceship because, for one thing, I think it takes away from the incredible real facts we know about this object. And in my view of the universe, aliens are definitely not impossible-- there could be other life outside the earth. There could even be other technologies outside the eart...

Harvard scientists think that the first interstellar object detected in our solar system, called “Oumuamua,” could be an alien spacecraft. The scientists sought to explain a quirk in Oumuamua's behavior, which led them to an unusual conclusion. No one knows what Oumuamua is or where it came from, and it's too late to find out for sure. ------------------------------------------------------ #Aliens #Space #ScienceInsider Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.

The key to our spacefaring future. Hosted by Seth Shostak and Molly Bentley. It’s not a bird or a plane, and probably not an alien spaceship, although the jury’s still deliberating that one. Some astronomers have proposed that an oddly-shaped object that recently passed through our Solar System could be an alien artifact. We consider the E.T. explanation for ‘Oumuamua, but also other reasons asteroids are invigorating our imagination. Are these orbiting rocks key to our future as a spacefaring species? Find out why traditional incentives for human exploration of space – such as political rivalry –aren’t igniting our rockets the way they once did, but why the potentially trillions of dollars to be made mining asteroids might. These small bodies may also hold the key to our ancient past: the New Horizons flyby of Thule in early 2019 will provide an historic look at a distant Kuiper belt object, and provide clues about the formation of the Solar System.

(2018) https://go.nature.com/2A9FncQ Last year a visitor came to our inner solar system. To us it looked like a faint spot of light, moving quickly relative to the fixed stars. We’d seen similar things countless times before – lonely rocks, remnants from the formation of our solar system, drifting on their endless orbits around the sun and faintly glimmering with its reflected light. Nothing unusual about such asteroids and comets, but what made this object special was its trajectory. It was not in orbit around the Sun at all. Rather, it appeared to have fallen in from interstellar space, and was on its way back out again. The object is 1I/2017 U1, better known as ‘Oumuamua. It’s the first chunk of interstellar space debris we’ve ever spotted passing through our solar system. It caused a justifiable stir at the time. Hell, WE even did an episode on it.
