Gaia's view of our galactic neighbours
Measuring the positions and motions of more than a billion stars, ESA's Gaia mission will refine our knowledge about our place in the Universe, providing the best ever star chart of our Milky Way and its neighbouring galaxies.
Giant storms cause palpitations in Saturn's atmospheric heartbeat
Immense northern storms on Saturn can disturb atmospheric patterns at the planet's equator, finds the international Cassini mission. This effect is also seen in Earth's atmosphere, suggesting the two planets are more alike than previously thought.
Green light for continued operations of ESA science missions
ESA's Science Programme Committee (SPC) has approved indicative extensions, up to 2019-2020, for the operation of eight scientific missions.
Herschel data links mysterious quasar winds to furious starbursts
Astronomers have used ESA's Herschel Space Observatory to solve a decades-old mystery about the origin of powerful cool gas winds in the hot environs of quasars. The evidence linking these powerful winds to star formation in the quasar host galaxies may also help resolve the mystery of why the size of galaxies in the Universe appears to be capped.
Stellar motions in nearby galaxy hint at underlying dark matter
By pinning down, for the first time, the three-dimensional motions of individual stars in the nearby Sculptor dwarf galaxy, astronomers have shed new light on the distribution of invisible dark matter that pervades the galaxy. This study combined the positions of stars measured by ESA's Gaia mission with observations from the NASA/ESA Hubble Space Telescope taken twelve years earlier.
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.
