A new analysis of the 3i/atlas of our solar system inter -starry interlockets reveals that it causes a huge amount of water – and astronomers cannot immediately explain why.
An object believed to have been a comet showed a strong exhaust of ultraviolet rays, which is a definite product of hydroxyl gas (OH), a side water, when astronomers depicted it with NASA Neil Gehrels Swift Space Telescope, before the sun disappeared. The exhaust could only be seen from space, as the ultraviolet light would be absorbed in the atmosphere.
Their conclusions, detailed in a new study published Letters of astrophysical magazines, Claims that all that oh is that the comet displaces water steam when the casting speed is around £ 88 per second – this is about the same speed as the fire hose, which explodes completely, according to a press release.
The most extraordinary thing is that it was noticed quite far from the Sun at a distance of about three astronomical units (AU) from the heliumcentric distance, or three times the distance between the Earth and our star. Usually, the comet stray much closer to the sun until the water in the water in their core, called the nucleus, begins to sublimate or instantly turns into the gas to gas. Someone else must be water emissions in 3i/Atlas – which also means that the comet comet must have a large water store to continue this process.
“When we detect water or even a weak ultraviolet echo, and from interstellar comet, we read a note from another planetary system,” said Auburn TK Physics Professor Caauthor Dennis Bodewits. “It tells us that the ingredients of chemistry of life are not specific to ourselves.”
This is another example of the charming interstellar objects such as 3I/Atlas. Think about it as very far, perhaps tens of millions of light -years, examples, looking directly through our thresholds. The fact that in many ways is strange compared to local comes, it indicates how the unique sphere of alien sphere should be and how we have much more to understand how the star systems are formed and how their structures can develop.
Usually a comet coma, a huge aura of gas and dust, which gives the comes a glowing appearance, begins to form as the object approaches the sun or other star, and is likely to heat up. Heat or sublimates or evaporates a substance in its center, which is many times smaller than a coma that attracts our eyes from the Earth. While he is traveling, the coma stretches behind the comet, forming the tail of his brand.
The 3i/Atlas Coma has already watched us in many ways. Its chemistry is strange compared to our own comets, and it looks like it has a stunningly high ratio of carbon dioxide to water.
It is still unclear what causes water vapor discharge. Astronomers speculate that the sun’s rays can warm the ice grain released from the nucleus, which are then evaporated into the surrounding coma.
Astronomers believe that the 3I/Atlas came from the center of the Milky Way, where they were probably launched from their original star system due to gravitational disturbance, such as a close flying of another star, encouraging interstellar space before eventually driving through our sun’s neighborhood. Based on these findings, astronomers estimate that the comet must be billions of years, perhaps three billion years older than the sun itself. This is not only an image of a different part of the galaxy, but also a completely different space era.
Currently, the sun is flying 3i/atlas, so we can watch it from the ground. However, scientists managed to look at it using spacecraft near Mars, and at the end of November it will soon turn to the full image.
“Every interstellar comet so far was a surprise,” said the main author Zexi Xing, a researcher at the Auburn University Podoctory, in his report on a job stating two previously discovered interstaries. “Oumuamua was dry, Borisov was rich in carbon monoxide, and now the Atlas is giving up water from a distance where we did not expect it.”
“Each of them,” Xing added, “what we think we rewrote about how planets and comet are formed around the stars.”
