Just in time to celebrate the 42nd anniversary of the publication of The Hitchhiker’s Guide to the Galaxy.
Daphne looks like a teardrop. Osonia resembles a squished jelly bean. Cleopatra is shaped like a dog’s bone. They are the only three asteroids out of 42 detected by the European Southern Observatory’s Very Large Telescope in Chile. Asteroids represent some of the largest in our solar system, and the images are helping astronomers learn about the origins of these fascinating space rocks.
“The detailed images of these 42 objects are a leap forward in the discovery of asteroids, made possible thanks to ground-based telescopes, and contribute to the answer to the ultimate question of life, the universe and everything,” ESO said in a statement on Tuesday. Huh.” Referencing author Douglas Adams on the 42nd anniversary of the publication of the science-fiction classic The Hitchhiker’s Guide to the Galaxy.
Asteroid observations from the Very Large Telescope, including the 3D sizes and densities of the objects, are included in a paper published this week in the journal Astronomy & Astrophysics. Reconstruction of the asteroids shows that they are either spherical or elongated, as is the case with the strange-looking Cleopatra.
The data suggests that asteroids may have radically different densities. “Our observations provide strong support for substantial migration since the formation of these bodies. In short, such tremendous diversity in their composition can only be understood if the bodies originated in different regions of the Solar System.,“said co-author Josef Hanus of Charles University in the Czech Republic.
The asteroids in the Very Large Telescope image archive are located in the “main belt” between Mars and Jupiter. The study suggests that the least dense asteroids may have formed beyond the orbit of Neptune and then moved to their current location in the Solar System.
The very spherical dwarf planet Ceres is involved in the observations. It was visited by NASA’s Dawn spacecraft and is one of the most well-studied objects in the asteroid belt. Another famous asteroid on the list is Psyche, the.
Asteroids are a hot topic in astronomy.One main-belt asteroid and seven other Trojan asteroids to visit on Saturday. Space agencies have also been busy To bring back to Earth for study. The ESO image project isn’t as dramatic as touching down on the surface of an asteroid, but it is filling in some important blanks in the study of these interesting objects.
