12 April 2020 Stephen Clark

Working with a reduced staff due to coronavirus-related restrictions, European Space Agency flight controllers monitored the BepiColombo spacecraft during a flyby of Earth on Friday, a maneuver that used our planet’s gravity to steer the mission on a course toward Mercury.

The European Space Agency’s Rosetta spacecraft closed in Thursday for a deliberate crash landing on the surface of comet 67P/Churyumov-Gerasimenko on Friday, a slow-motion kamikaze plunge to bring the enormously successful mission to an end after more than two years of unprecedented close-range observations.

Flight director explains how Rosetta will descend to the comet’s surface

Gaia, the space probe that has been mapping a billion stars in the Galaxy following its launch by the European Space Agency (ESA) in December 2013, has revealed its first revolutionary data.

Philae found! Rosetta’s lander wedged in cometary crevice

5 September 2016 Astronomy Now

Less than a month before the end of the mission, Rosetta’s high-resolution camera has revealed the Philae lander wedged into a dark crack on Comet 67P/Churyumov–Gerasimenko. The images were taken on 2 September by the OSIRIS narrow-angle camera as the orbiter came within 2.7 kilometres of the comet’s surface.

First stars formed even later than previously thought

2 September 2016 Astronomy Now

ESA’s Planck satellite has revealed that the first stars in the universe started forming later than previous observations of the Cosmic Microwave Background indicated. This new analysis also shows that these stars were the only sources needed to account for reionising atoms in the cosmos, having completed half of this process when the universe had reached an age of 700 million years.
