Special Issue Information
Dear Colleagues,
Space missions to comets and Kuiper Belt Objects have confirmed that planets were probably born by the gravitational collapse of pebble clouds triggered by streaming instability processes in the protoplanetary disk. In this Special Issue, we will review the physical processes forming dust in the interstellar medium, how dust evolved in the protosolar nebula, and how it accreted into pebbles in the protoplanetary disk, according to laboratory experiments of collisions among dust particles. We will review dust data collected on comets, supporting structural models of these objects, i.e., the most pristine bodies in our solar system. We will compare cometary dust to that collected on asteroids, bodies that underwent heavy collisional processes. Finally, we will follow how dust released by cometary activity and asteroidal collisions feed the interplanetary dust cloud today, observed as zodiacal light.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Universe is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
