Hubble observes rare asteroids worth 10,000,000,000,000,000,000 USD at close range



There is a very rare metal Asteroid Lurking between Mars and Jupiter, its value goes far beyond the entire global economy. Now, the Hubble Space Telescope allows us to take a closer look at this object, and its value is estimated at US$100 million.

A new study in this week’s Journal of Planetary Science explores the mystery of the asteroid 16 Psyche more deeply than ever before, one of the largest objects in the solar system’s main asteroid belt orbiting between Mars and Jupiter. 1. It is about 230 million miles from the earth. It is about 140 miles in diameter-roughly the size of Massachusetts.

Most asteroids are made of rock or ice. But 1

6 Psyche is dense and mainly made of metal. It may be that the remaining core of the planet was never successfully formed-the so-called “protoplanet”, whose core is exposed after the collision and running collision, and its core is exposed. Mantle.

This research marks the first ultraviolet (UV) observation of celestial bodies. New data shows that asteroids may be made entirely of iron and nickel and exist in the dense cores of planets.

Lead author Dr. Tracy Becker said in a statement: “We have seen meteorites. These meteorites are mainly metallic, but Sage may be unique because it may be made entirely of iron and Asteroids made of nickel. “The earth has a metal core, mantle and crust. When the Pseudoplanet was formed, it could be hit by another object in the solar system and lost its mantle and crust. “

Scientists studied the asteroids at two points where the asteroids revolved, so that the details of both sides can be fully observed at ultraviolet wavelengths. They found that the surface might be mainly iron, but warned that even a small amount of iron would dominate the UV observation.

Becker said: “We can find for the first time on any asteroid the ultraviolet absorption band that we think is iron oxide.” “This shows that oxidation is occurring on the asteroid, which may be the result of the solar wind hitting the surface.”

The solar wind is a stream of charged particles from the upper atmosphere of the sun (called corona) throughout the solar system. It is responsible for the comet tail flying through the sky, the formation of aurora, and the possible “spatial weathering” of Psyche.

The researchers also said that the asteroid became more and more reflective at deeper ultraviolet wavelengths, which may indicate its age.

Becker said: “This is something we need to study further.” “This may indicate that it has been exposed to space for so long. This ultraviolet brightening is usually attributed to space weathering.”

Metal asteroids are rare, so Psyche provides researchers with an exciting opportunity to study the interior of planets. In 2022, NASA plans to launch the unmanned spacecraft Psyche on the SpaceX Falcon Heavy rocket to study asteroids to understand the history of asteroids and the history of similar objects-the first mission is to visit objects made entirely of metal.

The orbiter is scheduled to arrive at the asteroid in January 2026 and will study it for nearly two years. The mission leader at Arizona State University estimates that in today’s market, the value of iron alone will reach $10,000 trillion-that is one iron, and then 19 zeros.

Becker said: “What makes Psyker and other asteroids so interesting is that they are considered the basis of the solar system.” “It is fascinating to understand what a planet really constitutes and potentially see the inside of a planet. Once we arrive Psyche, we really need to understand whether this is the case, even if it does not appear as we expected, there will always be surprises, always exciting.”

The researcher told CBS News After the mission is confirmed in 2017, they do not plan to use the value of asteroid composition.

Carol Polanskey, the project scientist of the Psyche mission, said at the time: “We will understand the formation of planets, but we will not try to bring these materials back and use them in industry.”
