• Five reasons to join the European Space Agency!

  

  In 2023, ESA published more than 400 vacancies in engineering, science and business and administration and more positions continue to be published as we are always on the lookout for talented new colleagues to join us. So, what does it mean to join ESA? Here are five reasons why you should consider ESA as the next step in your career!

• Swarm detects tidal signatures of our oceans

  

  A study using data from ESA’s Swarm mission suggests that faint magnetic signatures created by Earth’s tides can help us determine magma distribution under the seabed and could even give us insights into long-term trends in global ocean temperatures and salinity.

• Malargüe: A satellite dish best served cold

  

  A capacity increase by almost 80%! In late July 2024, the Malargüe deep-space communication station completed an important upgrade of its antenna feed that will allow missions to send much more data back to Earth.

• Hubble traces hidden history of the Andromeda Galaxy

  

  The largest photomosaic of the Andromeda galaxy, assembled from NASA/ESA Hubble Space Telescope observations, unveils hundreds of millions of stars. It took more than 10 years to collect data for this colorful portrait of our neighbouring galaxy and was created from more than 600 snapshots. This stunning, colourful mosaic captures the glow of 200 million stars, and is spread across roughly 2.5 billion pixels.

• EarthCARE goes live with data now available to all

  

  With ESA’s EarthCARE satellite and four measuring instruments all working extremely well and fully commissioned, the mission’s ‘first level’ data stream is now freely available.

  By combining data from all four instruments, scientists ultimately aim to address a critical Earth science question: how do clouds and aerosols affect the heating and cooling of our atmosphere?

• The best Milky Way animation, by Gaia

  Video: 00:02:05

  This is a new artist’s animation of our galaxy, the Milky Way, based on data from ESA’s Gaia space telescope.

  Gaia has changed our impression of the Milky Way. Even seemingly simple ideas about the nature of our galaxy’s central bar and the spiral arms have been overturned. Gaia has shown us that it has more than two spiral arms and that they are less prominent than we previously thought. In addition, Gaia has shown that its central bar is more inclined with respect to the Sun.

  No spacecraft can travel beyond our galaxy, so we can’t take a selfie, but Gaia is giving us the best insight yet of what our home galaxy looks like. Once all of Gaia’s observations collected over the past decade are made available in two upcoming data releases, we can expect an even sharper view of the Milky Way.
