Researchers have discovered the first galaxy to hit Earth, according to a recently released United States space command document. A stellar meteorite is a space rock that forms outside our solar system – a rare phenomenon.

This is called CNEOS 2014-01-08, and it crashed on January 8, 2014 off the northeast coast of Papua New Guinea.

The discovery came as a surprise to Amir Siraj, who identified the object as a meteorite in a joint study he conducted in 2019 while a bachelor’s graduate at Harvard University.

Siraj studied Om Loamuwa, the first known galaxy in our solar system, discovered in 2017 with Abraham Lope, a science professor at Harvard University.

Siraj decided to go through NASA’s near-Earth object research database to find other galaxies, and in a few days discovered what he believed to be a galaxy meteorite.

Speed ​​required

The speed of the meteorite initially caught Siraj’s eye.

The meteorite moves around the Sun at a speed of 28 miles per second (45 kilometers per second) compared to Earth moving at about 18.6 miles per second. Because researchers have measured how fast a meteorite moves on a moving planet, 45 kilometers per second is not really how fast it travels.

The center speed of the Sun is defined as the speed of the meteorite relative to the Sun, which is the most accurate way to determine the orbit of an object. It is calculated based on the angle at which a meteorite strikes the Earth. The planet moves in one direction around the sun, so the meteorite may have collided directly with the earth, i.e. opposite or behind the direction the planet is moving, in the same direction the earth is moving.

As the meteorite hit the Earth from behind, Siraj’s calculations showed that the meteorite was actually traveling at 37.3 miles per second compared to the Sun.

He then mapped the path of the meteorite and found that, unlike the closed orbit of other meteorites, it was in uncontrolled orbit. This means that it came from outside the solar system, rather than orbiting the sun like other meteors.

“Presumably, it was made by another star, ejected from that star’s planetary system, and went into our solar system and collided with Earth,” Siraj said.

Difficulty publishing

Lope and Siraj could not publish their findings in a journal because their data came from NASA’s CNEOS database, which did not publish information on how accurate the readings were.

After many years of trying to get the necessary additional information, they received official confirmation from John Shaw, the Deputy Commander of the U.S. Space Command, that it was indeed a galaxy. This command is part of the U.S. Department of Defense and is responsible for military operations in space.

“Dr. Joel Moser, Chief Scientist at the Space Operations Command, a United States space force service unit of the U.S. Space Command, reviewed the analysis of additional data available to the Department of Defense regarding this discovery. Dr. Moser confirmed the velocity estimate. Wrote in the letter.

Siraj engaged in other research and almost forgot about his discovery, so the document came as a shock.

“I thought we would never know the true nature of this meteorite. After many of our efforts it was blocked somewhere in the government, so it was really an incredible moment to actually see that letter from the Department of Defense with my own eyes.” Siraj said.

Second chance

After receiving confirmation, Siraj said his team would resubmit his findings for publication in a scientific journal.

Siraj wants to unite a team to recover a part of the meteorite that fell in the Pacific Ocean, but admitted that it was not possible due to the sheer size of the project.

Siraj said that if researchers could get their hands on the “holy grail of interstellar objects,” it would be scientifically amazing to help scientists discover more about the world beyond our solar system.

NASA and the US space command did not initially respond to a request for comment.
