Oumuamua: an ancient alien solar sail sat? (video).

In this 40-minute-long video, we examine how iIn late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system. Harvard astronomer Avi Loeb concluded that the object (which became known as ‘Oumuamua) was not an asteroid or comet; it was moving too fast along a strange orbit, and left no […]

Oumuamua: new theory, but extraterrestrial lightsail is still the most likely explanation (video).

Some scientists are now trying to explain away the Oumuamua interstellar visitor as a frozen slice of a Neptune-like planet, without explaining why said lump didn’t melt when it crossed the Sun, how it could be 3mm thick, or accelerated evenly and constantly, rather than at random-walk outgassing speeds. In this half-hour video, the Angry […]

Oumuamua: Avi Loeb says it may have been an alien solar-sail visitor (audio).

In this hour-long audio interview with the Planetary Society, Avi Loeb, the Frank B. Baird, Jr. Professor of Science at Harvard University, chats about why the first incoming object known to have originated outside our solar system might be a light-sail device – either a probe or a nav-buoy – built by an alien civilisation. […]

Oumuamua: first alien solar-sail probe to visit the Solar System? (science video)

Avi Loeb, the Frank B. Baird, Jr., Professor of Science and astrophysicist at Harvard University, explains why in his new book, Extraterrestrial: The First Sign of Intelligent Life Beyond Earth, he examines the evidence that our first interstellar visitor to be spotted in our solar system, Oumuamua, might be the first sign of intelligent life […]

Avi Loeb, Harvard Professor of Astrophysics, on why the Oumuamua visitor was an alien light-sail craft (video).

Avi Loeb, Harvard Professor of Astrophysics, on why the Oumuamua visitor was more likely than not to have been a light-sail powered piece of alien tech – either a probe, or just a relay in a comms network – as well as why humanity and Earth really aren’t special; why our Sun is a relative […]

Interstellar object Oumuamua might be alien probe, now solid hydrogen concept disproved (science news).

In 2018, the solar system experienced a visiting object flying by from interstellar space. The object, dubbed ‘Oumuamua, seemed to be long and thin — cigar-shape. Deep space scanners then showed it was accelerating for a fly-past of the solar system (rather than being captured by one of our planets or star’s gravity wells), with […]

Was ‘Oumuamua’ a light sail probe visiting the Solar System? Dr. Avi Loeb chats.

Dr. Avi Loeb of Harvard University (as well as the Harvard Smithsonian Center for Astrophysics) does a little video about the background and science behind the oddness of the recent fly-through of the Oumuamua object, and why science suggests it might have been a solar sail probe of some sort on a fly-by.

Oumuamua’s odd speed-up: NASA has one theory, UFOlogists, another.

Using observations from NASA’s Hubble Space Telescope and ground-based observatories, an international team of scientists have confirmed Oumuamua, the first known interstellar object to travel through our solar system, received a rather strange boost in speed and shift in trajectory as it passed through the inner solar system last year. “Our high-precision measurements of Oumuamua’s […]
