[视频]Hubble gives two stories of this journey.

The NASA Hubble telescope recently took a look at the asteroid 6478 screenings. The way in the picture shows that the asteroid moves slowly towards self-destruction as a result of the continued illumination of the sun.We first noticed in January this year that asteroid detected decades ago has become comedy. But Hubble's latest results show that this spacepiece will fall completely.

The asteroid 6478 Gault is described as being in the asteroid zone between Jupiter and Mars and has a width of about 2.5 miles (4 km).

Although we are in the decades, we have produced several telescope ideas. But last November, scientists discovered strange changes.

In January this year, Gault showed a block of similar dust, extending over 249,000 miles (400,000 kilometers). At the time, some astronauts believed that colliding with another object could remove the asteroid.

But a new paper from the international research team gives a different perspective – even in foreign lands, the Gault is about to fall apart.

The newspaper correspondent, Olivier Hainaut, from the Southern Theater of Europe, is set out in a press release: "This destructive event is very rare."

The good news is that active and unsustainable asteroids such as Gault are now found by new scanning telescopes that completely scan the sky. This means that the strange asteroid like Gault will no longer be removed.

According to the illustration taken by Telescope Space Hubble, Gault drew two long and narrow pieces of “tail”, showing that these materials were thrown out shortly, saving a few hours. took a couple of hours.

It is reported that around 800,000 asteroids are identified in the asteroid zone around Mars. But astronomers think the phenomena like Gault is only available once a year.

The reason for the Gault is so light-colored on behalf of Yarkovsky-Keefe-Radzievskii-Paddack (known as the YORP chasar).

It refers specifically to the interaction between electromagnetic radiation from the sun and small items such as asteroids, which can cause the second faster and narrower.

One of the papers, Jan Kleyna of the University of Hawaii, explained: “It could have been in an unstable condition for 10 million years, so even a slight disturbance (such as miniature effect) could cause the t … t his tail was blown. ”

As the dust remains small in a spot in the coming months, the asteroid 6479 Gault will go out into our sight.

Details of the survey will be published in the recently published Astrophysical Journal Letters.
