Euclid_is_back_26_million_galaxies_and_c Video: 00:06:44

The European Space Agency’s Euclid mission has scouted out the three areas in the sky where it will eventually provide the deepest observations of its mission.

In just one week of observations, with one scan of each region so far, Euclid already spotted 26 million galaxies. The farthest of those are up to 10.5 billion light-years away.

In the coming years, Euclid will pass over these three regions tens of times, capturing many more faraway galaxies, making these fields truly ‘deep’ by the end of the nominal mission in 2030.

The first glimpse of 63 square degrees of the sky, the equivalent area of more than 300 times the full Moon, already gives an impressive preview of the scale of Euclid’s grand cosmic atlas when the mission is complete. This atlas will cover one-third of the entire sky – 14 000 square degrees – in this high-quality detail.

Explore the three deep field previews in ESASky:

-          Euclid Deep Field South

-          Euclid Deep Field Fornax:

-          Euclid Deep Field North:

      Sol 4553: Back to the Boxwork!
      NASA’s Mars rover Curiosity acquired this image of its workspace in the “boxwork” terrain area, showing resistant, ridge-like features where it will investigate the targets dubbed “Sisquoc River” and “Palo Verde Mountains.” Curiosity acquired the image using its Left Navigation Camera on May 27, 2025 — Sol 4552, or Martian day 4,552 of the Mars Science Laboratory mission — at 08:38:12 UTC.

      Earth planning date: Tuesday, May 27, 2005
      We return to planning today after a successful long weekend and about 42 meters of drive distance (about 138 feet). We planned four sols of activities on Friday to keep Curiosity busy, while the U.S.-based science team and engineers took time off yesterday for the Memorial Day holiday. As we got to admire the new workspace and drive direction view in front of the rover this morning, I realized that we have now driven about 35 kilometers (about 22 miles) and climbed more than 850 meters (2,789 feet) in elevation since landing nearly 13 years ago, and we continue to do exciting science on Mars, having recently driven onto new terrain. 
      The so-called boxwork structures are a series of resistant ridges observed both from orbit and in long-distance rover imaging (see Ashley’s blog here). Not only are the ridges of interest (do they indicate enhanced fluid-flow and cementation?), but the outcrop expression in general changed after we drove over a shallow trough onto the rocks that host the ridges.
      This plan will continue characterization of the interesting boxwork terrain. We had an example of a more resistant, ridge-like feature in our workspace today (see accompanying image). The composition of the ridge will be investigated using ChemCam (target “Sisquoc River”) and APXS (target “Palo Verde Mountains”), with accompanying Mastcam and MAHLI images. We will also acquire Mastcam imaging of a trough-like feature surrounding a bedrock slab, as part of our ongoing documentation of such structures, as well as of an apparent resistant boxwork ridge in the distance (“Lake Cachuma”). And a first for our mission, we are planning the longest-distance ChemCam remote imaging mosaic that we will have acquired — 91 kilometers (almost 57 miles) away! The intent is to compare the long-distance view from the ground with HiRISE orbital images in an attempt to create a 3D view. We also managed to squeeze in a Navcam large dust-devil survey before the planned 24-meter drive (about 79 feet). Once we arrive at our new location, MARDI will take an image of the terrain beneath the rover.
      The plan is rounded out with the standard REMS, DAN and RAD activities.

      This NASA/ESA Hubble Space Telescope image features the remote galaxy HerS 020941.1+001557, which appears as a red arc that partially encircles a foreground elliptical galaxy.ESA/Hubble & NASA, H. Nayyeri, L. Marchetti, J. Lowenthal This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years from Earth (but appearing as it did around 11 billion years ago, when the galaxy was 5.5 billion light-years away and began its trek to us through expanding space). Known as HerS 020941.1+001557, this remote galaxy appears as a red arc partially encircling a foreground elliptical galaxy located some 2.7 billion light-years away. Called SDSS J020941.27+001558.4, the elliptical galaxy appears as a bright dot at the center of the image with a broad haze of stars outward from its core. A third galaxy, called SDSS J020941.23+001600.7, seems to be intersecting part of the curving, red crescent of light created by the distant galaxy.
      The alignment of this trio of galaxies creates a type of gravitational lens called an Einstein ring. Gravitational lenses occur when light from a very distant object bends (or is ‘lensed’) around a massive (or ‘lensing’) object located between us and the distant lensed galaxy. When the lensed object and the lensing object align, they create an Einstein ring. Einstein rings can appear as a full or partial circle of light around the foreground lensing object, depending on how precise the alignment is. The effects of this phenomenon are much too subtle to see on a local level but can become clearly observable when dealing with curvatures of light on enormous, astronomical scales.
      Gravitational lenses not only bend and distort light from distant objects but magnify it as well. Here we see light from a distant galaxy following the curve of spacetime created by the elliptical galaxy’s mass. As the distant galaxy’s light passes through the gravitational lens, it is magnified and bent into a partial ring around the foreground galaxy, creating a distinctive Einstein ring shape.
      The partial Einstein ring in this image is not only beautiful, but noteworthy. A citizen scientist identified this Einstein ring as part of the SPACE WARPS project that asked citizen scientists to search for gravitational lenses in images.

      Sols 4539-4540: Back After a Productive Weekend Plan
      NASA’’s Mars rover Curiosity acquired this image using its Left Navigation Camera on May 11, 2025 — Sol 4537, or Martian day 4,537 of the Mars Science Laboratory mission — at 22:26:23 UTC. NASA/JPL-Caltech Written by Scott VanBommel, Planetary Scientist at Washington University
      Earth planning date: Monday, May 12, 2025
      Curiosity was back to work Monday, picking up where it left off from Friday’s plan. Tosol’s plan started with an APXS analysis on the target “Jeffrey Pine,” though the DRT was kept on the sidelines this time. Curiosity then proceeded to image Jeffrey Pine and “Canyon Oak” with MAHLI while simultaneously executing a DAN passive analysis. Mastcam documented “Santiago Peak” as well as Canyon Oak, prior to a ChemCam 5-spot analysis on the latter. Following a drive of about 30 meters (about 98 feet), Curiosity rounded out the two-sol plan with untargeted and environmental monitoring activities, including Navcam dust-devil and cloud-shadow movies.
