Comet C/2019 Y4 ATLAS, discovered in December 2019 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Mauna Loa in Hawaii is approaching the inner solar system. It is currently observed to be disintegrating.

Interstellar comet 2I/Borisov, discovered in 2019, has been seen breaking apart in March 2020.

Hubble Space Telescope observations indicate that fragments of the comet are drifting away, as reported in the Astronomer’s Telegram on April 2, 2020.

Comet 2I/Borisov, discovered on August 29, 2019, has astronomers intrigued as it is only the second known object to be have an orbit and velocity that suggests it is of interstellar origin. It’s orbit has an eccentricity of about 3.5. It will reach perihelion on December 7, 2019.

ESA’s Rosetta mission has concluded with a controlled descent into Comet 67P/Churyumov–Gerasimenko. “The descent gave Rosetta the opportunity to study the comet’s gas, dust and plasma environment very close to its surface, as well as take very high-resolution images… after becoming the first spacecraft to orbit a comet, and the first to deploy a lander, Philae, in November 2014.” More >

Rosetta’s OSIRIS camera team has launched a new website to showcase their recent images of Comet 67P/Churyumov–Gerasimenko.

Rosetta’s lander Philae has emerged from hibernation. Comet Lander Philae, which shut down 64 hours after the historic comet landing in November 2014, has sent back signals indicating that it is in good health.

ESA Post – June 14, 2015 | Twitter

In the 64 hours before the Philae comet lander went into hibernation, it conducted experiments, deployed all 10 instruments, and returned data that is now being analysed.  More >
