In its youth, our solar system was the site of the giant influences that created its image. Our solar system, and often other Milky Way planetary systems. But such an event has not yet been noticed. However, researchers are announcing today that they have found evidence that it happened.
In new planetary systems, collisions of bodies are not uncommon. The With a protoplanet called the size of Mars . But today, researchers say they have found evidence of such an impact on a planetary system other than ours. They go a little further by insisting that this impact, in a way, has “stripped” the extraterrestrial of its sound. .For example think ours Appeared about 4 billion years ago
The impact of the question occurred at just 95 . A Named HD 172555. A star 23 million years old. This collision is thought to have taken place about 200,000 years ago, between the size of our Earth and one planet Small, moving at no less than 36,000 kilometers per hour.Ours
HD 172555 attracted the attention of astronomers due to the unusual structure of the dust disk around it. Surprisingly rich record (MIT, US) dug from dataAtacama large millimeter array (Alma, Chile) Looking for signs (CO) – Because it is so bright – Around this funny star.And contains better grains than other circular disks that researchers are accustomed to reading. So are astronomers
Conflict betrayed by carbon monoxide
The researchers first confirmed the presence of CO in HD 172555. Then they measured its abundance. It is not less than 20%Is in the atmosphere . This is a lot. They also noted that the gas was surprisingly close to the star. Is only 10 times the distance between our earth and the earth . Surprisingly, CO is susceptible to photosynthesis. The There is an annoying tendency to break it. So it should not appear so close at such a close distance.
The only possibility that astronomers believe is that this carbon monoxide was produced by a massive impact that would have torn at least part of its atmosphere from a terrestrial planet. In the past the star was so close that there was no time to clear the gas. And is large enough to produce so much gas between two bodies.
Therefore, researchers conclude that the detection of CO around a star will become one of the characteristics for detecting giant impacted planetary systems. One way to finally better understand how garbage works after reality.
Spitzer detects volcanic eruptions from planetary collisions
Before the hot phase of his work began, Spitzer made a recordHas been strange On Around the youngest star, HD 172555. A group It has now been discovered that they are evaporated rocks and debris Pulled out of a recent confrontation between the two .

Spitzer is definitely coming to the center this time, especially following a post by a team of physicists. . Although we have already known for many years the traces left by recent asteroid collisions on planetary disks (a few million years ago), this is the first time similar remains have been found coming from but larger celestial objects.
In fact, in their publication, researchers estimate that they have HD 172555, a star 12 million years old and about 100 light-years away, at least the size of the moon that corresponds to an object coming from a titanic collision. And the size of one.
The center of the small one must have sunk into the gut of the big one and the heat given by the impact melted the large rocks, probably the bulk of the main body that came out of the collision. Heat and Published by the latter, which a 10 km To create what we know on earth (These are fragments of rock that melted and were ejected from a crater during the impact of a )
How many times all these results, Taken from the spectral analysis of light emitted by matter. In this case, the observations Developed by Spitzer’s tools SiO Steam and Solid, but , The terrain is very similar to the Obsidian and of course .
If we find more traces of rocks and dust, like the remnants of asteroid collisions already discovered by Spitzer, the presence of silicate vapors and fragments of molten rock cannot be ruled out. Explain the rapid, violent collision between two bodies of large size but not yet found on other disks forming planetary systems.
Astronomers and astronomers are trying to understand evolution Between a proto-Earth and a celestial body the size of Mars . Venus has a rotation against the other planets in the solar system and Uranus has a strong inclination of its axis (approximately 90) probably due to the primitive shock with a smaller planet.This is an important discovery because we know that conflicts like these will not be rare at the beginning of this history. Our moon is coming from one
The moon may be currently orbiting the main planet. Next generationsWe need to teach more.
