** A better view of an interstellar comet 2I\/Borisov<\/strong>: Hubble Observes New Interstellar Visitor | ESA\/Hubble<\/a><\/p>\n

On 12 October 2019, the NASA\/ESA Hubble Space Telescope provided astronomers with their best look yet at an interstellar visitor \u2014 Comet 2I\/Borisov \u2014 which is believed to have arrived here from another planetary system elsewhere in our galaxy.<\/em><\/p>\n

This observation is the sharpest\u00a0 view ever of the interstellar comet. Hubble reveals a central concentration of dust around the solid icy nucleus.<\/em><\/p>\n

Comet 2I\/Borisov is only the second such interstellar object known to have passed through our Solar System. In 2017, the first identified interstellar visitor, an object dubbed \u2018Oumuamua, swung within 38 million kilometres of the Sun before racing out of the Solar System.\u00a0<\/em><\/p>\n

\u201cWhereas \u2018Oumuamua looked like a bare rock, Borisov is really active, more like a normal comet. It\u2019s a puzzle why these two are so different,\u201d explained David Jewitt of UCLA, leader of the Hubble team who observed the comet.\u00a0<\/em><\/p>\n
