Johns Hopkins University (JHU) continues to pad its space community résumé with their interactive map, “The map of the observable Universe”, that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang. While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency, the National Science Foundation, and the Sloan Foundation.
It's been seven years since Oumuamua flew through our Solar System. In that time, theories have come and gone, but here's why the first Interstellar UFO almost certainly had an artificial origin! #space #uap #alien Please support my journey to the Cape!!

For the first time ever astronomers have studied an asteroid that has entered the Solar System from interstellar space. Observations from ESO’s Very Large Telescope in Chile and other observatories around the world show that this unique object was travelling through space for millions of years before its chance encounter with our star system. It appears to be a dark, reddish, highly-elongated rocky or high-metal-content object.The video is available in 4K UHD.

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 object, named 1I/2017 U1 (aka. ‘Oumuamua). In the months that followed, multiple follow-up observations were conducted to learn more about this visitor, as well as resolve the dispute about whether it was a comet and an asteroid.
This small object was discovered on October 19, 2017, by the University of Hawaii's Pan-STARRS 1 telescope on Haleakala, Hawaii. Subsequent observations by ESO’s Very Large Telescope and other telescopes showed that it had come to the Solar System from interstellar space. 1I/`Oumuamua made its closest approach to the Sun on September 9, 2017. Its hyperbolic orbit is highly inclined and it does not appear to have come close to any other Solar System body on its way in. 1I/`Oumuamua is now on its way out of the Solar System. 1I/2017 U1 seems to be a dark red highly-elongated metallic or rocky body, about 400 meters long. Before receiving the official designation and name `Oumuamua from the International Astronomical Union it was referred to as A/2017 U1 The name was chosen by the Pan-STARRS team. It is of Hawaiian origin and means "a messenger from afar arriving first." Credit: ESO, M. Kornmesser, L.Calcada.

Astronomers have found that ‘Oumuamua, the first interstellar object discovered in the Solar System, is moving away from the Sun faster than expected. Using data from ESO’s Very Large Telescope, and from NASA/ESA’s Hubble Space Telescope, a team of researchers concluded that ‘Oumuamua is most likely outgassing — suggesting that this enigmatic interstellar nomad is a peculiar comet rather than an asteroid.

Get an email announcement whenever we release a new video: On October 25, 2017, astronomers from NASA’s Minor Planet Center sent out an announcement that they needed help confirming the trajectory of an interesting object. Known as C/2017 U1 PANSTARRS, the object was moving quickly through the Solar System, on a path that would take it out into deep space. Astronomers were happy to oblige, providing dozens of observations within a few days, confirming that yes indeed, we were looking at the first asteroid that had come from interstellar space.

It whipped around the Sun, and then continued on its hyperbolic orbit out into deep space again. It passed near the Earth on October 14, then crossed the orbit of Mars on November 1st, by May 2018 it’ll be farther than Jupiter, and get past Saturn in early 2019. Astronomers around the world have been making continuous observations of the asteroid, using some of the largest telescopes on Earth and in space. But they’ve got to work quickly, by mid-December, it’ll be too dim to observe with any of our instruments.

This figure from the study illustrates some of the particle simulations in the research. In their first scenario, the simulated system only consists of the Sun and the Earth-Moon system. Its purpose was to isolate the effect of giant planets. Image Credit: Mukherjee et al. 2023.
This figure from the research compares Jupiter’s efficacy at capturing ISOs into near-Earth orbits compared to the Earth-Moon efficacy. The math is fairly complex, but basically, the x-axis shows excess hyperbolic velocity, and as that rises, capture efficiency decreases. Image Credit: Mukherjee et al. 2023.
This figure from the research shows the distribution of orbital parameters for known small Solar System bodies vs captured ISOs. The left panel shows Astronomical Units, the middle panel shows orbital eccentricity and the right panel shows inclination. Image Credit: Mukherjee et al. 2023.
This figure from the study shows the survival fraction of captured interstellar NEOs as a function of the lifetime in bound NEO orbits. It shows that only 0.1-1% of the captured objects survive in NEO orbits by 10 Myr, which is significantly shorter than the lifetime of known NEOs. Image Credit: Mukherjee et al. 2023.

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.

------------------------------------------ Today, I am thrilled to have a very special guest joining me, Dr. Avi Loeb. Dr. Loeb is a theoretical physicist and the Frank B. Baird Jr. Professor of Science at Harvard University, where he is the former chair of the Astronomy Department. He is also the author of numerous articles and books on astrophysics, cosmology, and the search for extraterrestrial life. Dr. Loeb discusses the enigma of Oumuamua, the mysterious interstellar object that captured the world's attention in 2017. Dr. Loeb has been at the forefront of the scientific investigation of Oumuamua. Avi shares some of his insights on what this strange visitor might reveal about the nature of our universe and our place in it. We also discuss how Avi’s peers and the Scientific community, in general, responded to the possibility of Alien technology. But our conversation will not be limited to astrophysics alone. Dr. Loeb is a champion of scientific curiosity, humility, and exploration, and he will talk about how these values have shaped his career and his approach to life. We will also touch on what he calls the three coming revolutions of AI Sentience, Longevity, and the discovery of Advanced Civilizations. AI and Aliens – what could go wrong So, join us for a fascinating and wide-ranging conversation with one of the most brilliant and visionary scientists of our time. Please enjoy Dr. Avi Loeb.

While it lacked typical cometary activity, ‘Oumuamua exhibited a notable non-gravitational acceleration, leaving experts struggling to explain its origins. Previous models suggested outgassing of hyper-volatile molecules, but inconsistencies remained. In this video, we explore a new theory, by Dr. Jennifer Bergman and Darryl Seligman, that proposes ‘Oumuamua's acceleration was caused by the release of entrapped molecular hydrogen, which formed from energetic processing of an H2O-rich icy body.

#interstellar #oumuamua #mystery NASA Scientists' Shocking New Revelation About 'Interstellar Spaceship' Oumuamua By the 2010s, astronomers had spent decades looking for objects from outside our own solar system. What would essentially be interstellar visitors from an alien star system. But to no avail. But it is when all hope seems to be lost, that some of the most marvelous things happen. It was something like that for these astronomers. After decades of finding absolutely nothing, multiple objects started arriving in our solar system. Scientists and astronomers from across the world, SETI and even NASA joined in the study of these mysterious visitors. One of the very first to arrive, was Oumuamua. Now a new revelation about the interstellar visitor has emerged. Subscribe to Orbit - / @orbit_btb
