Herschel's chronicles of galaxy evolution
Delving deep into the history of our cosmos, the Herschel Space Observatory scrutinised hundreds of thousands of star-forming galaxies, peering back in time to when the Universe was less than one billion years old. These observations probed the peak epoch of stellar production, about ten billion years ago, when galaxies were forming stars roughly ten times faster than their present counterparts.

The cosmic water trail uncovered by Herschel
During almost four years of observing the cosmos, the Herschel Space Observatory traced out the presence of water. With its unprecedented sensitivity and spectral resolution at key wavelengths, Herschel revealed this crucial molecule in star-forming molecular clouds, detected it for the first time in the seeds of future stars and planets, and identified the delivery of water from interplanetary debris to planets in our Solar System.

How Herschel unlocked the secrets of star formation
Surveying the sky for almost four years to observe the glow of cold cosmic dust embedded in interstellar clouds of gas, the Herschel Space Observatory has provided astronomers with an unprecedented glimpse into the stellar cradles of our Galaxy. As a result, giant strides have been taken in our understanding of the physical processes that lead to the birth of stars and their planetary systems.

Cassini concludes pioneering mission at Saturn
The international Cassini mission has concluded its remarkable exploration of the Saturnian system in spectacular style, by plunging into the gas planet's atmosphere.

Venus' mysterious night side revealed
Scientists have used ESA's Venus Express to characterise the wind and upper cloud patterns on the night side of Venus for the first time–with surprising results.

XMM-Newton Announcement of Opportunity (AO-17)
Proposals are solicited for observations with XMM-Newton in response to the seventeenth Announcement of Opportunity, AO-17, issued 22 August 2017. This AO covers the period May 2018 to April 2019 and is open to proposers from all over the world.

Eighth Call for PROBA2 Guest Investigator Program
The Royal Observatory of Belgium invites research proposals from potential Guest Investigators for the analysis of data from PROBA2's two solar observation instruments, SWAP and LYRA. Early-career post-docs and PhD students are particularly invited to apply, although proposals from more senior Guest Investigators are also encouraged. Proposals in response to this Call must be received by 24 September 2017, 23:59 CEST (21:59 UTC).

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.
