Heavy Metal Vapors Unexpectedly Found in Comets Throughout Our Solar System and Beyond
A new study by a Belgian team using data from the European Southern Observatory’s Very Large Telescope (ESO’s VLT) has shown that iron and nickel exist in the atmospheres of comets throughout our Solar System, even those far from the Sun. A separate study by a Polish team, who also used ESO data, reported that nickel vapour is also present in the icy interstellar comet 2I/Borisov. This is the first time heavy metals, usually associated with hot environments, have been found in the cold atmospheres of distant comets. ....

Gaseous nickel was shedding from interstellar comet 2I/Borisov when it briefly visited our solar system two years ago, according to a new study. Sounds like weird behavior for a comet, but as related research shows, the spewing of atomic metals might actually be a regular thing that comets do, whether they’re local or from across the Milky Way.

Two new papers, published in the journal Nature, are updating our understanding of comets, both in terms of their origins and the conditions under which they formed. Combined, the papers are allowing for an unprecedented comparative analysis, in which astronomers are contrasting local comets to one that formed far, far away. ....
