Athena was selected as the second large mission of #CosmicVision, and was later rescoped as #NewAthena. NewAthena will be the largest X-ray observatory ever built. It will investigate some of the hottest & most energetic phenomena in the Universe with unprecedented accuracy and

The industrial development of the @ESA_LISAmission kicked off mid 2025. Once the spacecraft design is finalised, construction can begin. The mission is planned to launch in 2035. Led by ESA, the LISA mission is a collaboration between ESA, NASA and the LISA consortium. 5/

The @ESA_LISAmission has three spacecraft flying in a triangular formation, 2.5 million km apart, exchanging laser beams. Inside them, two golden cubes are in free fall. Gravitational waves alter the distance between objects so LISA will measure the tiny distance changes

The @ESA_LISAmission will be able to detect these elusive waves from across the Universe and across a large range of frequencies. LISA will be the first mission to probe the history of the Universe by studying such waves. It will also study the nature of gravity itself. 3/

The @ESA_LISAmission will detect millions of gravitational signals to study: ⭐ ⭐ binary star systems in our Milky Way to understand their mutual evolution 🕳️ 🕳️pairs of massive black holes to discover how they were born ⭐ 🕳️ compact objects falling onto single supermassive

A #CosmicVision mission, the @ESA_LISAmission will be first gravitational wave detector in space. LISA will study these ripples in the fabric of space-time emitted during the most powerful events in the Universe, such as pairs of black holes coming together and merging. 1/

I admit I don’t understand that. Yes, I know of the historical background. But what is the use of a water tap that delivers boiling hot water to a sink that does not have plug so mixing w/ the cold water is impossible. Why not simply have cold only?

#Amaldi16 in Glasgow is kicking off.

Michi Benthaus studierte Luft- & Raumfahrttechnik und arbeitet bei der ESA. Als Rollstuhlfahrerin ist es ihr Ziel, Raumfahrt inklusiver zu machen und auch einmal selbst ins Weltall zu fliegen. Wir hatten ein spannendes Gespräch mit ihr! Hört rein! ⬇️🌍🧠🚀 https://t.co/W73UT3Rv8J

El observartorio europeo LISA supone la segunda revolución de las ondas gravitaciones. La primera la inició Einstein. Nos lo cuenta @CarlosFSopuerta (@ice_csic @IEEC_space):   https://t.co/L33bUzWdYY

🌪️ Watch particles whirl out from the Sun in giant, million-km twisters. 🥇@ESASolarOrbiter is the first to capture this on camera! By comparison: cyclones on Earth can reach heights up to 15 km.

The command to begin the manoeuvre was uplinked to Gaia via ESA's deep space antenna in Malargüe, Argentina, part of the agency's global Estrack network of satellite communication stations.

The team at ESA mission control has initiated @ESAGaia's final manoeuvre. The spacecraft is now moving away from the second Lagrange point to prevent it interfering with any current or future missions near this scientifically valuable point in space.
