A lonely beauty [heic1803]

Wed, 14 Feb 2018 16:19:00 UT

Beauty, grace, mystery – this magnificent spiral galaxy has all the qualities of a perfect galactic Valentine. Captured by the NASA/ESA Hubble Space Telescope, the galaxy NGC 3344 presents itself face-on, allowing astronomers a detailed look at its intricate and elegant structure. And Hubble's ability to observe objects over a wide range of different wavelengths reveals features that would otherwise remain invisible.



Leaky atmosphere linked to lightweight planet

Thu, 08 Feb 2018 09:24:00 UT

The Red Planet's low gravity and lack of magnetic field makes its outermost atmosphere an easy target to be swept away by the solar wind, but new evidence from ESA's Mars Express spacecraft shows that the Sun's radiation may play a surprising role in its escape.



Hubble delivers first insight into atmospheres of potentially habitable planets orbiting TRAPPIST-1 [heic1802]

Mon, 05 Feb 2018 15:58:00 UT

An international team of astronomers has used the NASA/ESA Hubble Space Telescope to look for atmospheres around four Earth-sized planets orbiting within or near TRAPPIST-1's habitable zone. The new results further support the terrestrial and potentially habitable nature of three of the studied planets. The results are published in Nature Astronomy.



ESA creates quietest place in space

Mon, 05 Feb 2018 13:16:00 UT

Imagine a packed party: music is blaring and you can feel the bass vibrate in your chest, lights are flashing, balloons are falling from the ceiling and the air is filled with hundreds of separate conversations. At the same time your cell phone is vibrating in your pocket and your drink is fizzing in the glass. Now imagine you can block out this assault on your senses to create a perfectly quiet bubble around you, only letting in the unmistakable voice of your best friend who's trying to get your attention from the other side of the room.



Stellar winds behaving unexpectedly

Fri, 02 Feb 2018 11:10:00 UT

ESA's XMM-Newton has spotted surprising changes in the powerful streams of gas from two massive stars, suggesting that colliding stellar winds don't behave as expected.






Cosmic Vision M4 candidate missions: presentation event

Fri, 05 May 2017 13:28:00 UT

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

Fri, 21 Apr 2017 15:21:00 UT

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

Mon, 16 Jan 2017 12:54:00 UT

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.
