But most scientists think the idea that we spotted alien technology in our solar system is a long shot.
* * *
One explanation? The object was propelled by an alien machine, such as a lightsail — a wide, millimeter-thin machine that accelerates as it's pushed by solar radiation. The main proponent of this argument was Avi Loeb, a Harvard University astrophysicist.
Now, in a new paper published Monday (Aug. 17) in The Astrophysical Journal Letters , Loeb and Thiem Hoang, an astrophysicist at the Korea Astronomy and Space Science Institute, argue that the hydrogen hypothesis couldn't work in the real world — which would mean that there is still hope that our neck of space was once visited by advanced aliens — and that we actually spotted their presence at the time.

Tiny micrometeorites reveal clues about the solar system's ancient past | Astronomy.com
The Ph.D. student at Imperial College London had collected 76 tiny grains of space dust that had fallen to Earth near the white chalk hills of the North Downs, close to his home in Kent, England. When Suttle used a microscope to study the sand-sized particles — found in a layer of 87-million-year-old rock — he recognized the characteristic shape of small round spherules, like metal droplets. But when he cut them open and looked inside, he was surprised by what he saw.
Early Solar System May Have Had Two Suns | Astronomy | Sci-News.com
In a paper published in the Astrophysical Journal Letters , Harvard University astrophysicists Avi Loeb and Amir Siraj show that an equal-mass stellar companion to the Sun in the solar birth cluster — the collection of stars that formed together with our star from the same dense cloud of molecular gas — at a separation of 1,000 AU would have increased the likelihood of forming the observed population of objects in the outer Oort Cloud and of capturing the hypothesized
An artist's conception of a potential solar companion, which theorists believe was developed in the Sun's birth cluster and later lost. If proven, the solar companion theory would provide additional credence to theories that the Oort Cloud formed as we see it today, and that Planet Nine was captured rather than formed in place.

Homework project leads to scaled solar system made with chalk in south Huntsville | WHNT.com
HUNTSVILLE, Ala. – With many students learning at home amid the global pandemic, one father-son duo took their lesson outside for the neighborhood to enjoy.
10-year-old Oliver has been studying the solar system along with the distance between each planet. Oliver and his father, Michael created a scaled version of the solar system that stretched just short of a mile.
Every morning Oliver and Michael walk the route, but this time they decided to take their homework assignment to the streets.

NASA Mission | NASA's Psyche mission to find out how our solar system was created; to explore
NASA looks to be all set to conduct a study on an asteroid which is called 16 Psyche which the space agency has said will give us an idea on how our solar system was born. The Psyche mission is basically a journey to a unique metal asteroid which is currently orbiting the Sun between Mars and Jupiter.

NASA explains, "The Psyche mission is a journey to a unique metal asteroid orbiting the Sun between Mars and Jupiter. What makes the asteroid Psyche unique is that it appears to be the exposed nickel-iron core of an early planet, one of the building blocks of our solar system.

What Shape Is Our Solar System? - What Solar System Looks Like
Our sun emits powerful solar winds that wrap around the planets in our solar system like a giant bubble. This magnetic bubble, called the heliosphere, protects the planets from harmful cosmic radiation jettisoned out in the wake of powerful cosmic events like supernovae.
After conducting a series of simulations using data from various NASA missions, a team of astronomers now believes our solar system's heliosphere may be shaped like a "deflated croissant." Personally, we see a jumbo shrimp.
