How do you find a star cluster? Easy, simply count the stars
It's the perfect meeting of old and new. Astronomers have combined the latest data from ESA's Gaia mission with a simple analysis technique from the 18th century to discover a massive star cluster that had previously escaped detection. Now, subsequent investigations are helping reveal the star-forming history of our Galaxy, the Milky Way.
Herschel discovers galaxy merger in the very early Universe
What seemed at first like a rare instance of a huge, ancient galaxy revealed itself to be an even rarer pair of extremely massive galaxies, seen on the brink of merging when the Universe was only a billion years old.
Webb's first space targets chosen
Gas giant Jupiter, organic molecules in star-forming clouds and baby galaxies in the distant Universe are among the first targets for which data will be immediately available from the James Webb Space Telescope once it begins casting its powerful gaze on the Universe in 2019.
Heating ocean moon Enceladus for billions of years
Enough heat to power hydrothermal activity inside Saturn's ocean moon Enceladus for billions of years could be generated through tidal friction if the moon has a highly porous core, a new study finds, working in favour of the moon as a potentially habitable world.
Launch your design with CHEOPS
ESA is offering graphic designers and artists a unique opportunity to feature their work on the rocket carrying the CHEOPS satellite.
Cosmic Vision M4 candidate missions: presentation event
ARIEL, THOR, and XIPE, the three candidates for the M4 medium-class mission in ESA's Science Programme, will be presented to the science community at a special event in Paris on 3 July 2017. The deadline to register for this event is 10 June.
ESA identifies new science ideas for future space missions
Last year, ESA called on the scientific community to propose new and innovative science ideas that could be relevant for future space missions within the Science Programme. From the proposals that were received three key areas of interest have been selected for further investigation.
ESA Planetary Science Archive gets a new look
Today, ESA launches a new version of its Planetary Science Archive (PSA) website, the online interface to data from the agency's space science missions that have been exploring planets, moons and other small bodies in the Solar System. With a new design and enhanced search functionalities, the platform now provides a direct and simple access to the scientific data, helping scientists to discover and explore the archive content.
