Há 3 horas · Quatro vezes maior que a Terra, o planeta tem um clima muito frio e com fortes ventos. Urano foi o primeiro planeta encontrado com o auxílio de um telescópio, descoberto pelo astrônomo William Herschel em 1781. Um dia em Urano leva cerca de 17 horas e a órbita ao redor do Sol, 84 anos terrestres.
Há 3 dias · William Herschel, discoverer of Uranus Before its recognition as a planet, Uranus had been observed on numerous occasions, albeit generally misidentified as a star. The earliest possible known observation was by Hipparchus , who in 128 BC might have recorded it as a star for his star catalogue that was later incorporated into Ptolemy 's Almagest . [26]
Há 2 dias · William Herschel la descubrió en 1784. Es parte del Cúmulo de Virgo y es una galaxia LINER. Con un ángulo de 36°, se ve casi de frente desde la Tierra.
Há 5 dias · William Herschel independently discovered the object in 1784 and additionally noted the presence of a "dark stratum" in the galaxy's disc, what is now called a dust lane. Later astronomers were able to connect Méchain's and Herschel's observations. Designation as a Messier object
Há 5 dias · But he died in 1616, and it wasn’t until Sir William Herschel first observed Uranus on March 13, 1781, that the faint object was determined to be the seventh planet in our solar system. Shakespeare obviously knew the name Uranus because it goes back to Greek mythology.
Há 11 horas · Single-dish far-infrared (far-IR) and sub-millimetre (sub-mm) point source catalogues and their connections with catalogues at other wavelengths are of paramount importance. However, due to the large mismatch in spatial resolution, cross-matching galaxies at different wavelengths is challenging. This work aims to develop the next-generation deblended far-IR and sub-mm catalogues and present ...
