NASA says Voyager 2 may be nearing interstellar space

  NASA says Voyager 2 may be nearing interstellar space Voyager 1 could soon welcome its twin to the space outside our solar system.Voyager 2 has been traveling through the heliosheath, the outermost layer of the heliosphere, for over a decade. NASA describes the heliosphere as a "vast bubble around the Sun and the planets dominated by solar material and magnetic fields.

NASA may have ruled that Oumuamua, the first interstellar object ever spotted in our system is a "metallic or rocky object" approximately 400 meters (1,312 feet) in length and 40 meters (131 feet) wide, but a new study from the Harvard Smithsonian Center for Astrophysics says it could be something much more exciting – it could be "a lightsail of artificial origin" sent from another civilization.

UFO-Like 'Space Junk' Washes Up On Shore

  UFO-Like 'Space Junk' Washes Up On Shore The object was found by Lowcountry Marine Mammal Network who were usually deployed to deal with animals struggling on the shoreline. The object was discovered on Seabrook Island on Thursday and photos surfaced over the weekend."Look at this mysterious object that washed ashore on Seabrook Island today! What do you think it is?" the group posted on Facebook.Immediately after the image circulated on social media, people came up with several theories to determine the type and origin of the object. The most likely explanation was the object was a dredge pipe float or part of a buoy.

The study, which was posted online earlier this month, suggests that Oumuamua's strange "excess acceleration" could be artificial in nature, as it has been implied that it is not an active comet.

"Considering an artificial origin, one possibility is that ‘Oumuamua is a lightsail, floating in interstellar space as a debris from an advanced technological equipment," researchers wrote in the paper.

The paper continues: "Lightsails with similar dimensions have been designed and constructed by our own civilization, including the IKAROS project and the Starshot Initiative. The lightsail technology might be abundantly used for transportation of cargos between planets or between stars."

Scientists: Mysterious Object in Solar System Could Be Alien

Scientists: Mysterious Object in Solar System Could Be Alien A mysterious object that passed through our solar system last year may have been part of a vessel sent by an alien entity to investigate Earth.

They even theorized that Oumuamua "may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization," though that scenario was called "exotic."

The paper was written by postdoctoral researcher Shmuel Bialy and professor Abraham Loeb, the director at the CfA's Institute for Theory and Computation.

Other studies have suggested that other "Oumuamua-like objects" will potentially enter our solar system, with some potentially carrying life.

"The likelihood of Galactic panspermia is strongly dependent upon the survival lifetime of the putative organisms as well as the velocity of the transporter," according to a paper published in The Astronomical Journal by Manasvi Lingam and the aforementioned Loeb.

They added: "Velocities between 10−100 km s−1 result in the highest probabilities. However, given large enough survival lifetimes, even hypervelocity objects traveling at over 1000 km s−1 have a significant chance of capture, thereby increasing the likelihood of panspermia."

Scientists push back against Harvard 'alien spacecraft' theory

Scientists push back against Harvard 'alien spacecraft' theory A scientific paper led by two researchers at Harvard University made a splash this week by claiming that a cigar-shaped rock zooming through our solar system may have been sent by aliens.

INTERSTELLAR VISITOR 'OUMUAMUA' NEVER SHOULD HAVE LEFT HOME, THEORIES SAY

Panspermia is the hypothesis that life on Earth originated from microorganisms in outer space that were carried here unintentionally by objects such as space dust, meteoroids and asteroids, according to an article on NASA's website.

Oumuamua, which is the Hawaiian name for "pathfinder" or "scout," was discovered in October 2017 by the PanSTARRS1 telescope after it spotted a new spot of light coming from a strange direction at an unusually fast speed.

Since its discovery, researchers have debated whether it is a comet or an asteroid, though it was eventually determined to be a comet.

Oumuamua is traveling away from the Sun at a rate of approximately 70,000 mph, towards the outer part of the solar system. In approximately four years, it will whiz past Neptune's orbit, on its way to interstellar space.

There could be hundreds of interstellar asteroids lurking in our solar system.
These asteroids will stick around for a long time, so scientists can take their time learning everything about them. A year ago, astronomers spotted something no one had ever seen before: an object visiting our solar system from somewhere else in the galaxy. The object, dubbed ‘Oumuamua, is long since gone, heading rapidly out of our solar system just as quickly as it came. But now that we know interstellar asteroids exist, scientists have been on the hunt for more. And according to a new study by Harvard researchers, there may be plenty to find.
