Astronomers discovered the first evidence that a collision in deep space A group of astronomers, led by the Massachusetts Institute of Technology, have found evidence that the planetary system HD 172555 collided with an Earth-sized planet nearly 200,000 years ago. .

According to the British newspaper, “Daily Mail”, the collision occurred in planetary system 95 . away Light year At over 22,000 miles per hour, it may have caused a portion of the planet’s atmosphere to explode, as evidenced by carbon monoxide and dust surrounding HD 172555.

The researchers found that carbon monoxide was orbiting near HD 172555, roughly 10 AU, or roughly 930 million miles away, and the dense presence of gas near the star indicates that it emanated from a collision.

The impact is likely to be massive, and may include two protoplanets similar in size to Earth. The star HD 172555 has been of interest to scientists for some time. In 2009, NASA’s Spitzer Space Telescope found evidence of a high-speed collision around the star during the early stages. Of the planet’s composition, however, the telescope detected no evidence at the time it had partially stripped the planet’s atmosphere.

The group of researchers used data from the Atacama Large Millimeter Array in Chile and examined signs of carbon monoxide around nearby stars to reach their findings.
