ESA Webb Telescope

The bright orange lines appearing to radiate from the nucleus are diffraction spikes created by the interaction of light with Webb’s structure. For this pattern to occur, the light source must be very bright and very concentrated, such as M77’s nucleus.

This is an active galactic nucleus, powered by a supermassive black hole 80 million times as massive as our Sun. Gas is pulled into orbit around the black hole, where it crashes together and heats up, releasing tremendous amounts of radiation. Here's what it looks like in near-infrared! 2/3

🆕 Our ESA/Webb Picture of the Month catches a beacon of light in swirls of dust 🌀 The barred spiral galaxy Messier 77 (M77) lies 45 million light-years away in the constellation Cetus 🐋. This new image from Webb’s #MIRI highlights the galaxy’s piercingly bright core. 1/3

3. The correct answer is b) OPAL. This program has been observing Jupiter, Saturn, Uranus, and Neptune to understand their changing atmospheres.

2/ Hubble’s image was captured as part of which monitoring program?

🛎️ It's quiz time! Webb teamed up with @Hubble_Space to give us these new views of Saturn 🪐 showing layers and storms in its atmosphere!

So, astronomers used Webb and [HUBBLE LINK] to gaze into the cradles of star clusters 👶⭐ in four nearby galaxies from the FEAST programme. This image shows a star-forming nebula in the galaxy M51. These observations showed that the most massive star clusters emerge from their clouds the fastest, subsequently filling their surroundings with ultraviolet light! 2/3

🆕 Webb is revealing the secrets of star clusters! ✨ Stars form in clusters, created when clouds of gas collapse. Eventually, these young stars blast away their cloud. Our position in the Milky Way makes it difficult to watch this process in the closest star-forming regions. 1/3

In the 2026 ESA/Hubble and ESA/Webb calendar, the month of May puts the spotlight on Jupiter’s auroras. These auroras, captured here by Webb, are hundreds of times brighter than those on Earth. Ready to print .pdf here: esahubble.org/products/calen… 1/2

3. The correct answer is b) MIRI. Astronomers used two of Webb’s instruments, MIRI and NIRCam, to capture views of the Cranium Nebula in different wavelengths of infrared light. Read more: esawebb.org/news/weic2605/ 📷 @NASA , @ESA , @csa_asc , STScI, Image Processing: Joseph DePasquale (STScI)

2/ Which of Webb’s instruments captured this view of it?

🛎️ It's quiz time! Webb has recently helped astronomers peer inside the Cranium Nebula 🧠👀 which is being created by an aging star that is expelling its outer layers.

3. The correct answer is c) Its dustiness. The excess of dust around stars, which can dim their light to the point of undetectability, could help explain a long-standing problem in astronomy – the case of the missing red supergiants!

2/ What was notable about the supernova progenitor?

🛎️ It's quiz time! Webb teamed up with Hubble to identify a supernova progenitor in the galaxy NGC 1637 ⭐➡️💥

3. The correct answer is b) PMR 1. There is much still to be learnt about this nebula, such as the ultimate destiny of the star at its centre. Read more: esawebb.org/news/weic2605/ 📷 @NASA , @ESA , @csa_asc , STScI, Image Processing: Joseph DePasquale (STScI)

2/ What is the nebula’s official name?

🛎️ It's quiz time! Webb recently examined the Cranium Nebula 💀 with this view captured by its #NIRCam instrument.
