The European Southern Observatory recently released detailed images of 42 of the solar system's largest asteroids, captured by the observatory's VLT or Very Large Telescope in Chile.
A Firstpost report said that these sharpest images of the asteroids were put out with the date of release, and number serving as a tribute to Douglas Adams, a science fiction writer.
The observations of these asteroids, as this report stated, which were found between Mars and Jupiter, unveiled a wide range of the asteroids' unusual shapes "from dog-bone to spherical." The study is helping astronomers in outlining the asteroids' origin in the solar system.
Scientists have realized that the observed bodies can be split into two families following the reconstruction of their shapes.
Images in 3D Shape
The most recent images of the captured asteroids mean various key characteristics like their density of 3D shape, which had formerly stayed greatly unknown.
In a similar report, Phys.org said, through a combination of shapes of the asteroids with details on their masses, Vernazza, along with his team discovered that the objects' density varied substantially through the sample size.
Meanwhile, the four least dense asteroids including Lamberta and Sylvia had densities of roughly 1.3 grams per cubic centimeter, approximately equivalent to the coal's density.
Meanwhile, the densest asteroids identified as Kalliope and Psyche, which had densities higher than that of diamond equivalent to 4.4 and 3.9 gram-per-cubic centimeters respectively.
Formed Beyond Orbit of Neptune
Such results back the notion that the least dense asteroids migrated to their current location following their formation in the regions outside the orbit of Neptune.
According to Charles University's Josef Hanuš, the study offers robust support for the significant migration of these bodies since they were formed, adding that this was the lone explanation for the variety in terms of their composition.
Essentially, the asteroids' sample number was picked as a tribute to their series, The Hitchhiker's Guide to the Galaxy by Douglas Adam, which was published more than four decades ago on the same date.
Citing the writer, ESO said that the images, as shown on the observatory's YouTube video below, were a step ahead in the exploration of asteroids, giving credit to ground-based telescopes, and contributing the response to the ultimate question not of life, but the universe and everything, as well.
