BUFFALO charges towards the earliest galaxies [heic1816]
The NASA/ESA Hubble Space Telescope has started a new mission to shed light on the evolution of the earliest galaxies in the Universe. The BUFFALO survey will observe six massive galaxy clusters and their surroundings. The first observations show the galaxy cluster Abell 370 and a host of magnified, gravitationally lensed galaxies around it.

Saturn's famous hexagon may tower above the clouds
The long-lived international Cassini mission has revealed a surprising feature emerging at Saturn's northern pole as it nears summertime: a warming, high-altitude vortex with a hexagonal shape, akin to the famous hexagon seen deeper down in Saturn's clouds. This suggests that the lower-altitude hexagon may influence what happens up above, and that it could be a towering structure spanning hundreds of kilometres in height.

BepiColombo science orbiters stacked together
The two science orbiters of the joint ESA-JAXA BepiColombo mission are connected in their launch configuration and the European science orbiter and transport module have been given the go-ahead to be loaded with propellants.

Hubble observes energetic lightshow at Saturn's north pole [heic1815]
Astronomers using the NASA/ESA Hubble Space Telescope have taken a series of spectacular images featuring the fluttering auroras at the north pole of Saturn. The observations were taken in ultraviolet light and the resulting images provide astronomers with the most comprehensive picture so far of Saturn's northern aurora.

Artwork unveiled on exoplanet satellite
Two plaques etched with thousands of miniaturised drawings made by children have been unveiled in a dedicated ceremony held today in Switzerland.

XMM-Newton Announcement of Opportunity (AO-18)
Proposals are solicited for observations with XMM-Newton in response to the eighteenth Announcement of Opportunity, AO-18, issued 21 August 2018. This AO covers the period May 2019 to April 2020 and is open to proposers from all over the world.
