Swift mission tallied water from interstellar comet Borisov

For the first time, NASA’s Neil Gehrels Swift Observatory tracked water loss from an interstellar comet as it approached and rounded the Sun. The object, 2I/Borisov, traveled through the solar system in late 2019. Source: https://phys.org/news/2020-04-swift-mission-tallied-interstellar-comet.html…

Update on 2I/Borisov, the first known interstellar comet

Interstellar comet Borisov came from a cold and distant home star

The interstellar comet Borisov, which flew past Earth in December, is full of carbon monoxide ice that implies its home star is smaller and colder than our sun Source: https://www.newscientist.com/article/2240989-interstellar-comet-borisov-came-from-a-cold-and-distant-home-star/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

ALMA reveals unusual composition of interstellar comet 2I/Borisov

A galactic visitor entered our solar system last year—interstellar comet 2I/Borisov. When astronomers pointed the Atacama Large Millimeter/submillimeter Array (ALMA) toward the comet on 15 and 16 December 2019, for the first time they directly observed the chemicals stored inside an object from a planetary system other than our own. This research is published online on 20 April 2020 in the…

Will SETI 2.0 lead to a discovery of intelligent aliens?

Interstellar comet Borisov may be breaking up as it exits solar system

The first-ever interstellar comet is showing signs of brightening, suggesting it may have been heated up as it passed near to the sun Source: https://www.newscientist.com/article/2238063-interstellar-comet-borisov-may-be-breaking-up-as-it-exits-solar-system/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

New photographs of interstellar visitor revealed

NASA has released two new images of the interstellar comet Borisov as it careens through our solar system. First observed on August 30th, the comet, w… Source: https://www.unexplained-mysteries.com/news/333069/new-photographs-of-interstellar-visitor-revealed…

2nd-known interstellar visitor rounds the sun

The 1st interstellar object – 1I/’Oumuamua – had already passed closest to our sun when astronomers first spotted it. So catching this 2nd one – 2I/Borisov – prior to perihelion was a big plus for astronomers! Before and after images here.
