Hubble observes source of gravitational waves for the first time [heic1717]
The NASA/ESA Hubble Space Telescope has observed for the first time the source of a gravitational wave, created by the merger of two neutron stars. This merger created a kilonova – an object predicted by theory decades ago – that ejects heavy elements such as gold and platinum into space. This event also provides the strongest evidence yet that short duration gamma-ray bursts are caused by mergers of neutron stars. This discovery is the first glimpse of multi-messenger astronomy, bringing together both gravitational waves and electromagnetic radiation.
INTEGRAL sees blast travelling with gravitational waves
ESA's INTEGRAL satellite recently played a crucial role in discovering the flash of gamma rays linked to the gravitational waves released by the collision of two neutron stars.
Gaia data help prepare for a rare celestial alignment of Neptune's largest moon
On 5 October 2017, the largest moon of Neptune will pass in front of a distant star. This rare event will temporarily block the star's light from Earth and provide an excellent opportunity to study the moon's intriguing atmosphere. Data from ESA's Gaia mission is allowing astronomers to precisely plan their observations.
Biomarker found in space complicates search for life on exoplanets
A molecule once thought to be a useful marker for life as we know it has been discovered around a young star and at a comet for the first time, suggesting these ingredients are inherited during the planet-forming phase.
Helicopter test for Jupiter icy moons radar
A long radar boom that will probe below the surface of Jupiter's icy moons has been tested on Earth with the help of a helicopter.
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.
