Making a mosaic of the Sun
This animation shows how Solar Orbiter obtains its high-resolution full Sun views. While both the Extreme Ultraviolet Imager (EUI) and Polarimetric and Helioseismic Imager (PHI) instruments on the spacecraft are capable of imaging the entire Sun in a single shot, their high-resolution cameras only cover a small patch of the Sun at any one time.
To get a high-resolution view of the full solar disc, Solar Orbiter is first oriented to point to different regions across the Sun, usually in a 5 x 5 grid, with images taken at each pointing direction. These are then stitched together to create a much larger ‘mosaic’.
Shown here is how this was done on 9 March 2025. The animation shows the Sun as seen by EUI's Full Sun Imager. At each pointing direction, highlighted by the dark squares, the EUI instrument captured six images at high resolution and two wide-angle views. These 200 individual images were then combined to create the widest high-resolution image of the Sun yet. Combining mu
I had no idea of this project from NASA. I don't understand why the national media has not covered this. I only just found out about it by watching a recent video by Peter Santenello.
Rather than cycling, some of Mars’ carbon took a one-way trip into rocks.
Earth rotates, the Sun rotates, the Milky Way rotates – and a new model suggests the entire Universe could be rotating.
Astronomers Detect a Signature of Life on a Distant Planet
Further studies are needed to determine whether K2-18b, which orbits a star 120 light-years away, is inhabited, or even habitable.
The search for life beyond Earth has led scientists to explore many suggestive mysteries, from plumes of methane on Mars to clouds of phosphine gas on Venus. But as far as we can tell, Earth’s inhabitants remain alone in the cosmos.
Now a team of researchers is offering what it contends is the strongest indication yet of extraterrestrial life, not in our solar system but on a massive planet, known as K2-18b, that orbits a star 120 light-years from Earth. A repeated analysis of the exoplanet’s atmosphere suggests an abundance of a molecule that on Earth has only one known source: living organisms such as marine algae.
“It is in no one’s interest to claim prematurely that we have detected life,” said Nikku Madhusudhan, an astronomer at the University of Cambridge and an author of the new study, at a news conference on Tuesday. Still, he said, the best explanation for his group’s observations is that K2-18b is covered with a warm ocean, brimming with life.
“This is a revolutionary mome
JWST: MIRI - NGC 1514
[Image description: What looks like a single large, bright star (but is two) shines with bright purple diffraction spikes at the center of a large, diffuse cylinder of gas and dust that is tipped to the right. At the center is a bright pink clumpy cloud that takes up about 25% of the view. There are two large rings seen at a roughly 60-degree angle that appear joined at top left and bottom right. The edges are denser, and form shallow V-shapes that go inward. The rings appear orange at top left and bottom right, and are blue at bottom and center right. There is diffuse orange material around the body. The black background of space is speckled with tiny stars and galaxies mostly in blues and yellows. Areas Webb did not observe are along the top edges, a thin vertical near the nebula at top left, and at the bottom left and right corners.]

Webb captures detailed beauty of Ring Nebula (MIRI image)
The NASA/ESA/CSA James Webb Space Telescope has observed the well-known Ring Nebula with unprecedented detail. Formed by a star throwing off its outer layers as it runs out of fuel, the Ring Nebula is an archetypal planetary nebula. Also known as M57 and NGC 6720, it is both relatively close to Earth at roughly 2,500 light-years away.
This new image provides unprecedented spatial resolution and spectral sensitivity. In particular, Webb’s MIRI (Mid-InfraRed Instrument) reveals particular details in the concentric features in the outer regions of the nebulae’s ring (right).
There are some 20,000 dense globules in the nebula, which are rich in molecular hydrogen. In contrast, the inner region shows very hot gas. The main shell contains a thin ring of enhanced emission from carbon-based molecules known as polycyclic aromatic hydrocarbons (PAHs). Roughly ten concentric arcs located just beyond the outer edge of the main ring. The arcs are thought to originate from the interaction of th
On 19 March 2025, the European Space Agency’s Euclid mission released its first batch of survey data, including a preview of its deep fields. Here, hundreds of thousands of galaxies in different shapes and sizes take centre stage and show a glimpse of their large-scale organisation in the cosmic web...
Are the mysterious stars clues to one of the greatest mysteries in the universe?
Uncrewed Spectrum test rocket’s failure seconds after blast-off said to have produced extensive data nonetheless
A test rocket intended to kickstart satellite launches from Europe fell to the ground and exploded less than a minute after takeoff from Norway on Sunday, in what the German startup Isar Aerospace had described as an initial test.
The Spectrum started smoking from its sides and crashed back to Earth in a powerful explosion just after its launch from from the Andøya spaceport in the Arctic. Images were broadcast live on YouTube.
JWST: NIRCam - SMACSJ0028.2-7537
[Image Description: In the centre is an elliptical galaxy, seen as an oval-shaped glow around a small bright core. Around this is wrapped a broad band of light, appearing like a spiral galaxy stretched and warped into a ring, with bright blue lines drawn through it where the spiral arms have been stretched into circles. A few distant objects are visible around the ring on a black background.]

SMACSJ0028.2-7537 is the cluster that creates the lensing effect, the spiral galaxy is seen behind it.
JWST: NIRCam/MIRI - Herbig-Haro 49/50
[Image description: Angled from the upper left corner to the lower right corner of the image is a conical shaped orange-red cloud known at Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. At this same location there is a background spiral shaped galaxy with a concentrated blue center that fades outwards to blend in with red spiral arms. The conical feature widens slightly from the rounded end at the upper right down to the lower right. The black background of space is clearer, speckled with some white stars and smaller, more numerous, fainter white galaxies.]
The NASA/ESA/CSA James Webb Space Telescope has captured a beautiful juxtaposition of the nearby protostellar outflow known as Herbig-Haro 49/50 with a perfectly positioned, more distant spiral galaxy. Due to the close proximity of this Herbig-Haro object to Earth, this new composite infrared image ...
