Could Oumuamua Be an Extra-Terrestrial Solar Sail? – Universe Today

On October 19th, 2017, the Panoramic Survey Telescope and Rapid Response System-1 (Pan-STARRS-1) in Hawaii announced the first-ever detection of an interstellar asteroid, named 1I/2017 U1 (aka. ‘Oumuamua). In the months that followed, multiple follow-up observations were conducted that allowed astronomers to get a better idea of its size and shape, while also revealing that it had the characteristics of…

‘Oumuamua, Thin Films and Lightsails

‘Oumuamua, Thin Films and Lightsails by on The interstellar object called ‘Oumuamua continues to inspire analysis and speculation. And no wonder. We had limited time to observe it and were unable to obtain a resolved image to find out exactly what it looks like. This morning I want to go through a new paper from Shmuel Bialy and Abraham Loeb…

‘Oumuamua could be an alien device, say Harvard scientists

'Oumuamua is an oddly shaped, puzzling celestial object because it doesn't act like anything naturally occurring. The issue? The unexpected way it accelerated near the Sun. Is this our first sign of extraterrestrials? It's pronounced: oh MOO-uh MOO-uh. That odd-shaped visitor from beyond our solar system, 'Oumuamua (Hawaiian for "scout"), has been fascinating from the moment it arrived: It's a…

Harvard researchers raise the possibility that it may be "a fully operational probe sent intentionally to Earth vicinity by an alien civilization." (NBC News) - Maybe it's an alien spacecraft.Scientists have been puzzling over Oumuamua ever since the mysterious space object was observed tumbling past the sun in late 2017. Given its high speed and its unusual trajectory, the reddish,…

Search Fails To Find Artificial Radio Signals From Interstellar Object ‘Oumuamua | IFLScience

Last year, astronomers spotted the very first interstellar visitor to our Solar System. They called it ‘Oumuamua (oh-MOO-a-MOO-a), the Hawaiian word for "scout", and in the last 13 or so months it has been studied extensively. Of course, nothing new can be discovered in space without people screaming "Aliens!". The SETI (Search for Extra-Terrestrial Intelligence) Institute was of course curious,…

6 Strange Facts about the Interstellar Visitor ‘Oumuamua

On October 19, 2017, the first interstellar object, ‘Oumuamua, was discovered by the Pan-STARRS survey. The experience was similar to having a surprise guest for dinner show up from another country. By examining this guest, we can learn about the culture of that country without the need to travel there—a good thing in this case, given that it would take…

Wild Idea: What If Interstellar Visitor ‘Oumuamua Is an Alien Light Sail?

The odd interstellar object that zoomed through the inner solar system last fall might be an alien spacecraft with a light sail, a new study suggests. Indeed, an artificial origin would explain quite nicely the many weird characteristics of that cosmic visitor, which is known as 'Oumuamua, study co-author Avi Loeb said.  And Loeb said his colleagues shouldn't dismiss this…
