Cheops dell'ESA trova un anello inaspettato attorno al pianeta nano Quaoar

Cheops dell'ESA trova un anello inaspettato attorno al pianeta nano Quaoar

IMMAGINE: Artist impression of Quaoar and its ring An artist’s impression of the dwarf planet Quaoar and its ring. Quaoar’s moon Weywot is shown on the left. Quaoar’s ring was discovered through a series of observations that took place between 2018 to 2021. Using a collection of ground-based telescopes, and ESA’s space-based telescope Cheops, astronomers watched as Quaoar crossed in front of a succession of distant stars, briefly blocking out their light as it passed.

This is Quaoar, a dwarf planet in the outer Solar System. At a distance of about five times its radius sits a ring. This ring is made up out of small grey pieces of debris. At twice the distance of the ring, to the left of Quaoar, sits its moon Weywot. Weywot looks about a sixth the size of Quaoar but has the same brownish colour. To the right of this system, we see a bright star. This star is bigger than the background stars and represents the distant Sun.] Acknowledgement: Work performed by ATG under contract for ESA © ESA, CC BY-SA 3.0 IGO

Webb detects extremely small main-belt asteroid

Webb detects extremely small main-belt asteroid

A previously unknown 100–200-metre asteroid — roughly the size of Rome’s Colosseum — has been detected by an international team of European astronomers using the NASA/ESA/CSA James Webb Space Telescope. Their project used data from the calibration of the Mid-InfraRed Instrument (MIRI), in which the team serendipitously detected an interloping asteroid. The object is likely the smallest observed to date by Webb and may be an example of an object measuring under 1 kilometer in length within the main asteroid belt, located between Mars and Jupiter. More observations are needed to better characterize this object’s nature and properties.
