Computer exam | Clearest images of 42 largest objects in the asteroid belt revealed

Published

on

The European Southern Observatory (ESO), located in Chile, using the Very Large Telescope (VLT) instrument has detected images of 42 of the largest asteroids. is located in the asteroid belt located between the orbits of Mars and Jupiter. “Never before has such a clear image of such a large group of asteroids been obtained. Observations show a wide variety of unusual shapes, ”ESO said in a statement. These more detailed observations help scientists trace the origins of asteroids in the solar system.

“To date, only highly detailed images of three large main-belt asteroids – Ceres, Vesta and Lutetia – have been captured by NASA’s Dawn and ESA Rosetta spacecraft,” explains Pierre Vernazza of the Space Research Laboratory. The astrophysicist from Marseille, France, who led this study, published in the journal Astronomy and astrophysics… “Our observations now show very clear images of many other objects, 42 objects in total.”

This image shows the 42 largest objects in the asteroid belt, located between Mars and Jupiter. Most of them are more than 100 kilometers, and the two largest asteroids – Ceres and Vesta – have a diameter of about 940 and 520 kilometers, and the two smallest – Urania and Ausonia – are only about 90 kilometers each. The asteroid images were captured with the Spectropolarimetric High Contrast Exoplanet Research Instrument (SPHERE) on the very large ESO telescope.

Between 2017 and 2019, Vernazza and his team surveyed the major bodies of the asteroid belt to solve the problem of missing important details such as the three-dimensional shape or density of asteroids. “Most of 42 objects this sample has a dimension of more than 100 km; in particular, the team photographed virtually all asteroids in the belt over 200 km in size, that is, 20 out of 23. The two largest objects observed were Ceres and Vesta, with a diameter of about 940 and 520 km, respectively, and the smallest were Urania and Ausonia– both are only 90 km, ”explains ESO.

These observations also allowed the team to understand that the observed asteroids are essentially divided into two groups, the team explained. Some of them are almost perfectly spherical, for example Hygiene and Ceres, others have more unusual shapes such as Cleopatra, which, according to scientists, has the shape of a “dog bone”. After combining information regarding the shape and mass of the asteroids, the team further realized that the density varied significantly across the entire sample, thus concluding that the four least dense asteroids, including Lambert and Sylvia, have a density of about 1.3 grams per cubic centimeter, which is about the same density as coal, while denser ones such as Psyche and Calliope, have a density of 3.9 and 4.4 g / cm3correspondingly higher than the density of diamond. Thus, a large difference in signal density suggests that the composition of the asteroids is changing.

“Our observations convincingly confirm the significant migration of these bodies after their formation. In short, this diversity in their composition can only be understood if the bodies originated in different regions of the solar system, ”explains Josef Hanusz from Charles University in Prague, Czech Republic, one of the authors of the study. Thus, these results support the theory that less dense asteroids formed in distant regions of the solar system, beyond the orbit of Neptune, and then migrated to their current position.

These results are made possible by the tool SPHERE (Study of spectro-polarimetric high-contrast exoplanets), juntamente com o VLT ESO. “The improved capabilities of SPHERE, coupled with the fact that little is known about the shape of the largest asteroids in the main belt, have allowed us to make significant progress in this area of ​​research,” says co-author Laurent Jorda. also from the University of Astrophysics of Marseille.

with the future Extremely large telescope (ELT) of ESO under construction in Chile, astronomers expect to get even more detailed images of bodies in the asteroid belt. The ELT is expected to be operational by the end of this decade. “ELT observations of asteroids in the main belt will allow us to study objects with a diameter of 35 to 80 km, depending on their location in the belt, and craters with sizes from about 10 to 25 km,” says Vernazza. “Also, if we have a tool like SPHERE installed on the ELT, we might even be able to get images of a set of similar objects, but located in the far Kuiper belt! In this way, we were able to characterize from scratch the geological history of a much larger sample of small bodies.“, he adds.

Windows 11 Android Microsoft apps sub-sistema

The arrival of Android apps in Windows 11 marks a major milestone in this system and in Microsoft’s own ecosystem. Thus, the software giant was able to deliver on a promise made a few months ago.

With a clearly defined offering, we will now have access to everything that Android has to offer, right on the desktop and without a smartphone. Now that they are available, the first tests are showing up and the results are better than expected.


It was yesterday when Microsoft publicly launched Android apps in its new Windows 11. This opens up the possibility for us to have everything we have today in smartphones without depending on them.

The list of apps is still small, but it gives the user a very accurate idea of ​​what they will have access to. Of course, later, and not only through the Amazon store, users will be able to download more applications and thus expand the available range.

It was for sure via download applications using alternative methods (unpublished download and apks) which could be tested already the performance of this Android subsystem. With just 716MB of RAM, the resulting performance is promising for this new feature.

The evaluation purchased the performance of the hardware running Windows 11 and the Android subsystem itself. Despite limited resources and software, the results haven't lagged far behind.

Microsoft Windows 11 Android Application Subsystem

We found a performance decrease of about 12% in single-core tests and 11% in multi-core tests. It is also likely that there is still some optimization to be done and these values ​​will improve.

It is interesting to note Microsoft's huge investment in Android in Windows 11. Thus, the software giant wants to conquer another market by providing a bridge between its system and Android. The goal seems to have been achieved, even with constant improvements, which it will definitely receive in the near future.
