This week’s image is from the European Space Agency’s (ESA) Euclid space telescope. It shows the center of the Milky Way Galaxy with its more than 60 million stars.
Here is more from ESA pertaining to what you are seeing above:
The galactic bulge – the central region of our galaxy – is a vast, tightly packed structure filled mainly with old, cooler stars, giving it its characteristic yellow colour. Seen from some 26 000 light-years away, Euclid observes the galaxy’s centre through a complex foreground of material along its line of sight.
This ultra-wide view towards the bulge reveals not only stars, but also seemingly empty dark regions. The dark patches are not devoid of stars: they mark dense, dust-rich molecular clouds that absorb and scatter light from the bulge behind them. As Euclid looks through two of the Milky Way’s spiral arms, it also encounters regions of active star formation, traced by newly formed, massive blue stars. Their intense ultraviolet radiation ionises surrounding hydrogen gas, producing the faint red glow clearly visible in one of the cutouts.
The image below provides more context about the location of the image shown above. Go to this link for more information on the Euclid’s survey.

The Smile spacecraft lifted off on a Vega-C rocket from Europe’s Spaceport in French Guiana at 04:52 BST / 05:52 CEST (00:52 local time) on 19 May 2026. The launch marks the beginning of an ambitious mission to better understand solar storms, geomagnetic storms, and the science of space weather…Smile is a collaboration between the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS). It will reveal how Earth responds to the streams of particles and bursts of radiation from the Sun, using an X-ray camera to make the world’s first X-ray observations of Earth’s magnetic shield, and an ultraviolet camera to watch the resulting northern lights non-stop for 45 hours at a time.
Nasa announced on Tuesday ambitious plans for three uncrewed lunar missions this year to kickstart construction of a $20bn moon base, and said it had chosen the Amazon founder Jeff Bezos’s Blue Origin, ahead of Elon Musk’s SpaceX, to conduct the first...[NASA’s Administrator] said the three missions planned for 2026 would be followed by “more than a dozen” more in the coming years to test systems and equipment. He said the highly successful Artemis II mission last month that sent four astronauts around the moon for the first time since 1972 had been both a catalyst and incentive to advance the moon base plan.
Every morning, clouds roll in, and by evening, they have cleared off. This sounds like a weather forecast for a coastal city here on Earth — but it’s for WASP-94A b, a well-studied gas giant orbiting a star located nearly 700 light-years away. A new study published in the journal Science documents the first detection of repeating cloud cycles on a hot Jupiter exoplanet. The first author of the study is Sagnick Mukherjee, a 51 Pegasi b postdoctoral fellow at Arizona State University’s School of Earth and Space Exploration. Mukherjee is part of a research team that analyzed data from the James Webb Space Telescope targeting WASP-94 A b, a gas giant in the constellation Microscopium. The team discovered that the planet’s morning side is blanketed in clouds of magnesium silicate, the same mineral found in common rocks, while its evening side is under clear skies.
NASA released a much-anticipated contract solicitation for a Mars-orbiting spacecraft late last week, kicking off what is sure to be a hotly contested and potentially controversial procurement. At issue is $700 million, already appropriated by Congress, to build a spacecraft, launch it to Mars, and once there to serve as a vehicle to relay communications between the red planet and Earth. But the stakes may be even bigger than this, including the possible resurrection of the recently canceled Mars Sample Return mission. As part of the new solicitation, NASA says it will conduct the acquisition “as a full and open competition.” But will it? That’s the question that several people involved with this procurement process are asking. And it could turn messy, quickly.
A European intravehicular activity (IVA) spacesuit prototype developed under a CNES-initiated programme was transported to the International Space Station (ISS) aboard a SpaceX Dragon spacecraft. The spacesuit will be tested aboard the station by ESA astronaut Sophie Adenot. The EuroSuit project was initiated by CNES in December 2023 as part of the agency’s Spaceship FR programme, which aims to foster the development of core technologies required for future crewed missions beyond low Earth orbit.
The combination of the Shenzhou-23 crewed spacecraft and the Long March-2F Y23 carrier rocket was transferred to the launchpad at Jiuquan Satellite Launch Center in northwest China on Saturday, according to the China Manned Space Agency. All facilities and equipment at the launch site are in good condition. Various pre-launch functional inspections and joint tests will be carried out as scheduled in the coming days. The launch is planned to take place in the coming days.

It’s simply offering an option if listening while driving is preferable to you. I do not use AI in the written articles. I will also start posting the latest podcasts in the sidebar.

This week’s image is from the James Webb Space Telescope (JWST) and Hubble Space Telescope, which together scanned about 9,000 star clusters in the four galaxies. What you are looking at above comes from the spiral arm of one of the galaxies – Messier 51 (M51).
A large, long portion of one of the spiral arms in galaxy M51. Red-orange, clumpy filaments of gas and dust that stretch in a chain from left to right comprise the arm. Shining cyan bubbles light up parts of the gas clouds from within, and gaps expose bright star clusters in these bubbles as glowing white dots. The whole image is dotted with small stars. A faint blue glow around the arm colours the otherwise dark background.

This week’s image is from the Hubble Space Telescope. It shows spiral galaxy NGC 3137 in all its glory. We are getting a nice inclined view of the galaxy, allowing us to see multiple arms of stars.
A spiral galaxy seen close up and tilted at an angle, so that its disc fills the view from corner to corner. Its disc is yellow near to the centre and pale blue farther out, showing cooler and hotter stars, respectively. Thin brown clouds of dust, glowing pink spots of star formation, and sparkling blue patches filled with star clusters swirl through the galaxy. Behind it, small orange dots are very distant galaxies.
