SUKABUMIUPDATE.com Astronomers plan to entice meteorites falling into the ocean using magnets.
The meteorite came from another star system that crashed into the Pacific Ocean with an energy equivalent to about 121 tons of TNT.
Known as CNEOS 2014-01-08, a team of astronomers from Harvard University hopes to find an interstellar rock fragment that collided with Earth on January 8, 2014.
Amir Siraj, an astrophysicist at Harvard University, told Live Science, Monday (15/8/2022). ,
Siraj identified the object’s origin with 99.999 percent confidence in a 2019 study, but it was not until May 2022 that Siraj was confirmed by the United States Space Command.
There is no known witness of an object hitting Earth.
“It hit the atmosphere about 160 kilometers off the coast of Papua New Guinea in the middle of the night, with a force equivalent to about 1 percent of the energy of the Hiroshima bomb,” Siraj said.
CNEOS 2014-01-08 measures 0.5 meters and appears to be the first interstellar object discovered in the Solar System.
CNEOS 2014-01-08 is believed to be from another star system as it is moving at 60 kilometers per second relative to the Sun. The object is too fast to be bound by the Sun’s gravity.
In the latest mission, Siraj and his colleagues will conduct a $1.6 million mission to reduce the magnet to the location where the meteorite fell.
According to Siraj, CNEOS 2014-01-08 the strength of normal ferrous meteorite materials far exceeds that, which should make them easier to recover.
The strength of a material determines how easily something can withstand deformation or damage from a load.
Siraj also said that most meteorites contain enough iron that it will cling to the type of magnet we would use in ocean missions.
Siraj concluded, “Given the very high strength of the material, it is very likely that the 2014-01-08 CNEOS fragment is ferromagnetic.”
This project named Galileo will use ships with the help of magnetic sledges.
It will be carried to sea shore at a depth of 1.7 km for 10 days.
It is hoped that the magnet can recover a tiny 0.004-inch piece of the meteorite.
However, it is not yet clear when the astronomers will be able to carry out the mission given the required funding.
