First omissions of the interstellar comet suggest that it is not so different



Astronomers are in a hurry to explore what appears to be the first 1945 known interstellar comet – and in some of its earliest observations it seems strangely familiar.

The object, now called Comet C / 2019 Q4, was first spotted on 30 August. Subsequent observations of his path indicate that the comet is passing through our neighborhood on a one-way trip, not trapped in an orbit cycle characteristic of objects born in our own solar system. This would only make it the second confirmed interstellar object after 'Oumuamua, which was spotted in 2017.

But scientists could not read well what Oumuamua had created. However, with this object, they can obtain such readings by measuring the light signature of the rifle around the comet . Some of the first spectra for the C / 201

9 Q4 are present and look quite similar to the spectra of object classes in our solar system. This assumes that these objects and the interstellar visitor consist of more or less the same things.

"Comets in other planetary systems may be similar to those of the solar system," said in a statement Javier Lacandro, an astronomer at the Canary Astrophysics Institute . "They may have been formed by processes similar to those that led to the formation of Oort comets in the cloud in the solar system."

The Cloud The Oort Cloud is the spherical envelope of ice bodies that encloses our solar system over vast distances from the sun. We see comets as they are thrown out of the Oort cloud and travel closer to the heart of our solar system. They cultivate their trademarked tail when solar radiation evaporates the more volatile constituents of the comet.

Scientists have noticed comets that ricochet in other solar systems before but objects are difficult to study at such great distances. While Oumaamawa was definitely interstellar, he did not carry the mosquito erosion of the broadcast . The recently spotted object makes it, and this is what Lacandro and his colleagues at the Canary Astrophysics Institute were able to study.

The team uses a telescope in the Canary Islands to map a comet on September 12 and apply a mounted instrument to collect three spectra as well. Initial analyzes of these spectra suggest that they are somewhat aligned with those of a specific group of solar system objects . This could mean that the solar system from which the object is coming follows a recipe quite similar to that of our own solar system and its comets.

And scientists have plenty of time to gather the many observations they will need to better understand what a comet is made of and where it came from. Unlike when Oumaamua was discovered, astronomers believe they still have an entire year to observe a comet from Earth.
