Astronomers want to attract meteorites from the ocean using magnets

Nation World News – Astronomers offer a plan to trap falling meteorites in the ocean using magnetic rocks. What are the details of this scheme?

gazetted surah.comThis 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 is hoping to find a piece of interstellar rock that collided with Earth on January 8, 2014.

,Finding such a piece would be humanity’s first contact with material larger than the dust of the outer Solar System.Amir Siraj, an astrophysicist at Harvard University, was quoted by 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 at midnight, with a force equal to about 1 percent of the energy of the Hiroshima bomb.Siraj added.

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 undertake a $1.6 million campaign to reduce a magnet to the spot where the meteorite fell.

According to Siraj, CNEOS 2014-01-08 far exceeds the strength of normal ferrous meteorite material, which should make it easier to recover.

The strength of a material determines how easily something can withstand deformation or damage from a load.

According to Siraj, most meteorites contain enough iron that it will cling to the kind of magnets we’d use in ocean missions.

,Given the very high strength of the material, it is most likely that the CNEOS 2014-01-08 piece is ferromagnetic,“Siraj closed.

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 magnets can retrieve tiny fragments of the 0.004-inch meteorite.

However, it is not yet clear when the astronomers will be able to carry out the mission given the required funding.

That’s the plan of astronomers who want to entice meteorites falling into the ocean from magnetic rocks. (suara.com/lintang siltya utami),
