Interstellar Objects

Harvard astronomer Avi Loeb says aliens have visited us when the first-known interstellar object, ‘Oumuamua, entered our solar system. But does 'Oumuamua have anything to do with aliens? Finding intelligent life beyond our Earth could be the most game-changing event in human history.

On this episode of StarTalk Radio, Neil deGrasse Tyson, comic co-host Chuck Nice, and cosmochemist and author Natalie Starkey answer fan-submitted Cosmic Queries about ‘Oumuamua, the first detected interstellar object that passed through the solar system.  To start, Chuck wonders why we even study space rocks if they’re all the “same.” Natalie tells us how studying space rocks helps us understand our solar system when studying Earth only tells us so much. You’ll learn why asteroids might be the leftover building blocks from planets. We ponder what might be hiding in the Oort Cloud and why ‘Oumuamua is basically an interstellar vagabond.  You’ll find out more about ‘Oumuamua’s discovery and how it got its name. We also talk about the only other interstellar object we’ve documented (so far). What is the likelihood we will see another interstellar object? Natalie explains the difficult task of looking in the right place at the right time since interstellar objects can, literally, come from anywhere.  How do we differentiate an interstellar comet from a comet that came from the Oort Cloud? We explore the idea of panspermia. Could life survive such a perilous journey similar to ‘Oumuamua’s? Lastly, Natalie helps us understand why ‘Oumuamua’s shape is so peculiar. All that, plus, we ask the obvious question: was it sent by aliens?

In this interview with Avi Loeb, the Frank B. Baird, Jr., Professor of Science and astrophysicist at Harvard University, he explains why in his new book, Extraterrestrial: The First Sign of Intelligent Life Beyond Earth, he has put forth the theory that our first interstellar visitor to be spotted in our solar system, Oumuamua, might just be the first sign of intelligent life beyond earth.

Three years ago, we detected the first interstellar object passing through the Solar System, `Oumuamua. Ever since, astronomers have been debating the origins of this strange body. Whilst many hypothesize an asteroid, the media is ablaze with the possibility that it could be alien technology. Join us today for a discussion of this theory and the counter-arguments proposed.

'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.

What is the current trajectory of the interstellar comet borisov? With finding of interstellar comet borisov and the interstellar object oumuamua how many more interstellar objects are there in our solar system. Could Jupiter hold a repository of interstellar objects waiting for us to study? Should SpaceX build on the moon before going to mars? We explore these questions and more in this current and coming age of space and science discovery with Matt Williams, author and science reporter at Universe Today.
