Didn't have time for a new shot for Behind the lens this week, but I thought this was pretty good for the Week 24 theme - Light
This is a wood rasp with backlighting bounced off a optically coated piece of glass (and my slinky was also in play:-)

This the largest photomosaic ever assembled from NASA/ESA Hubble Space Telescope observations. It is a panoramic view of the neighbouring Andromeda galaxy, located 2.5 million light-years away. It took over 10 years to make this vast and colorful portrait of the galaxy, requiring over 600 Hubble snapshots. The galaxy is so close to us, that in angular size it is six times the apparent diameter of the full Moon, and can be seen with the unaided eye. For Hubble’s pinpoint view, that’s a lot of celestial real estate to cover. This stunning, colorful mosaic captures the glow of 200 million stars. That’s still a fraction of Andromeda’s population. And the stars are spread across about 2.5 billion pixels. The detailed look at the resolved stars will help astronomers piece together the galaxy’s past history that includes mergers with smaller satellite galaxies.
[Image description: The Andromeda galaxy, a spiral galaxy, spreads across the image. It is tilted nearly edge-on to our line of sight so that it appears very oval. The borders of the galaxy are jagged because the image is a mosaic of smaller, square images against a black background. The outer edges of the galaxy are blue, while the inner two-thirds is yellowish with a bright, central core. Dark, dusty filamentary clouds wrap around the outer half of the galaxy’s disk. At 10 o’clock, a smaller dwarf elliptical galaxy forms a fuzzy, yellow blob. Hubble’s sharp vision distinguishes about 200 million stars within the image.]

Today’s NASA/ESA Hubble Space Telescope Picture of the Week features the glorious spiral galaxy NGC 5643, which is located roughly 40 million light-years away in the constellation Lupus. NGC 5643 is what’s known as a grand design spiral, referring to how the galaxy’s two large, winding spiral arms are clear to see. The spiral arms are defined by bright blue stars, lacy reddish-brown dust clouds and pink star-forming regions.
As fascinating as the galaxy appears at visible wavelengths, some of NGC 5643’s most interesting features are invisible to the human eye. Ultraviolet and X-ray images and spectra of NGC 5643 show that the galaxy hosts an active galactic nucleus: an especially bright galactic core powered by a feasting supermassive black hole. When a supermassive black hole ensnares gas from its surroundings, the gas collects in a disc that heats up to hundreds of thousands of degrees. The superheated gas shines brightly across the electromagnetic spectrum, but especially at X-ray wavelengths.
NGC 5643’s active galactic nucleus isn’t the brightest source of X-rays in the galaxy, though. Researchers using ESA’s XMM-Newton discovered an even brighter X-ray-emitting object, called NGC 5643 X-1, on the galaxy’s outskirts. What could be a more powerful source of X-rays than a supermassive black hole? Surprisingly, the answer appears to be a much smaller black hole! While the exact identity of NGC 5643 X-1 is not yet known, evidence points to a black hole that is about 30 times more massive than the Sun. Locked in an orbital dance with a companion star, the black hole ensnares gas from its stellar companion, creating a superheated disc that outshines the galactic centre.
NGC 5643 was also the subject of a previous Picture of the Week. The new image incorporates additional wavelengths of light, including the red color that is characteristic of gas heated by massive young stars.
[Image Description: A close-up of a spiral galaxy, seen face-on. Its center is a bright white point, surrounded by a large yellowish oval with thin lines of dust swirling in it. From the sides of the oval emerge two bright spiral arms which wind through the round disc of the galaxy, filled with shining pink spots where stars are forming and more dark reddish dust. Many stars can be seen in the foreground, over and around the galaxy.]

Today’s ESA/Hubble Picture of the Week features the spiral galaxy NGC 4535, which is situated about 50 million light-years away in the constellation Virgo (The Maiden). This galaxy has been nicknamed the ‘Lost Galaxy’ because it’s extremely faint when viewed through a small telescope. With a mirror spanning 2.4 metres across, Hubble is well equipped to observe dim galaxies like NGC 4535 and pick out features like its massive spiral arms and central bar of stars.
On full display in this Hubble image are NGC 4535’s young star clusters, which dot the galaxy’s spiral arms. Many of the groupings of bright blue stars are enclosed by glowing pink clouds. These clouds, called H II (‘H-two’) regions, are a sign that the galaxy is home to especially young, hot, and massive stars that are blazing with high-energy radiation. By heating the clouds in which they were born, shooting out powerful stellar winds, and eventually exploding as supernovae, massive stars certainly shake up their surroundings.
This Hubble image incorporates data from an observing programme that will catalogue roughly 50 000 H II regions in nearby star-forming galaxies like NGC 4535. A previous image of NGC 4535 was released in 2021. Both the 2021 image and today’s image incorporate observations from the PHANGS programme, which seeks to understand the connections between young stars and cold gas. Today’s image adds a new dimension to our understanding of NGC 4535 by capturing the brilliant red glow of the nebulae that encircle massive stars in their first few million years of life.
[Image Description: A close-in view of a spiral galaxy that faces the viewer. Brightly lit spiral arms swing outwards through the galaxy’s disc, starting from an elliptical region in the centre. Thick strands of dark reddish dust are spread across the disc, mostly following the spiral arms. The arms also contain many glowing pink-red spots where stars form. The galaxy is a bit fainter beyond the arms, but speckled with blue stars.]

In this NASA/ESA Hubble Space Telescope Picture of the Week, Hubble has once again lifted the veil on a famous — and frequently photographed — supernova remnant: the Veil Nebula. This nebula is the remnant of a star roughly 20 times as massive as the Sun that exploded about 10 000 years ago. Situated about 2400 light-years away in the constellation Cygnus, this photogenic nebula made an appearance as the Picture of the Week previously in 2021.
This view combines images taken in three different filters by Hubble’s Wide Field Camera 3 instrument, highlighting emission from hydrogen, sulphur and oxygen atoms. This image shows just a small fraction of the Veil Nebula; if you could see the entire nebula without the aid of a telescope, it would be as wide as six full Moons placed side by side. Look in the sidebar of this page to see this image superimposed on its location in the sky, and try zooming out to compare the size of the full nebula!
Although this image captures the Veil Nebula at just a single point in time, it will help researchers understand how the supernova remnant has evolved over decades. Combining this snapshot with Hubble observations from 1994 will reveal the motion of individual knots and filaments of gas over that span of time, enhancing our understanding of this stunning nebula.
[Image Description: A colourful, glowing nebula that reaches beyond the top and bottom of the image. It is made of translucent clouds of gas: wispy and thin with hard edges in some places, and puffy and opaque in others. Blue, red and yellow colours mix together, showing light emitted by different types of atoms in the hot gas. Bright and pointlike stars are scattered across the nebula. The background is black.]

The subject of this NASA/ESA Hubble Space Telescope Picture of the Week is NGC 1637, a spiral galaxy located 38 million light-years from Earth in the constellation Eridanus.
This image comes from an observing programme dedicated to studying star formation in nearby galaxies. Stars form in cold, dusty gas clouds that collapse under their own gravity. As young stars grow, they heat their nurseries through starlight, winds, and powerful outflows. Together, these factors play a role in controlling the rate at which future generations of stars form.
Evidence of star formation is scattered all around NGC 1637, if you know where to look. The galaxy’s spiral arms are dotted with what appear to be pink clouds, many of which are accompanied by bright blue stars. The pinkish colour comes from hydrogen atoms that have been excited by ultraviolet light from young, massive stars. This contrasts with the warm yellow glow of the galaxy’s centre, which is home to a densely packed collection of older, redder stars.
The stars that set their birthplaces aglow are comparatively short-lived, and many of these stars will explode as supernovae just a few million years after they’re born. In 1999, NGC 1637 played host to a supernova, pithily named SN 1999EM, that was lauded as the brightest supernova seen that year. When a massive star expires as a supernova, the explosion outshines its entire home galaxy for a short time. While a supernova marks the end of a star’s life, it can also jump start the formation of new stars by compressing nearby clouds of gas, beginning the stellar lifecycle anew.
[Image Description: A spiral galaxy filling the view. Its disc is filled with bright red spots where stars are forming, dark reddish threads of dust that obscure light, and bluish glowing areas where older stars are concentrated. It has a large, glowing yellow oval area at the centre, from which two spiral arms wind through the galaxy’s disc. The bottom side of the disc is rounded while the top side is somewhat squared-off.]

The Copernicus Sentinel-1B satellite takes us over central Italy. From the Apennine Mountains in the top right, to the fertile, former lakebed of the Avezzano plain in the centre right, this bright, false-colour image captures the diversity and beauty of the region’s landscapes.
Dual-polarisation radar technology has been used, resulting in vibrant shades of green for most of the land surface shown. Built up areas, such as Italy’s capital city of Rome, appear in shades of red and pink. Meanwhile, the structure of the agricultural fields of Altopiano in the Abruzzo region is clearly reflected in a combination of blue and violet hues.
This radar technology allows us to see the crater lake structures of the volcanic lakes of Nemi and Albano in the bottom left clearly. The same is true for Lago di Vico with the volcano and crater clearly visible in the top left of the image.
The central region of Italy is an important one for the space industry. For example, ESA’s centre for Earth observation, which celebrates its 50-year anniversary this week, is located in this area.
This region is also prone to earthquakes. In August 2016, a magnitude 6.2 earthquake struck the small towns of Amatrice, Accumoli and Pescara del Tronto. It was followed by two aftershocks. A magnitude 6.6 earthquake in Norcia followed in October the same year. The tremor of this last earthquake was felt across the country. It was the most powerful one to hit Italy since 1980.
Sentinel-1’s radar technology can provide images with a resolution of 10 m and within hours of acquisition to aid emergency response. This imagery can support impact assessments for many types of hazard including floods and earthquakes.
This image, which was captured on 6 July 2018, is also featured on the Earth from Space video programme.

This Hubble Picture of the Week features the galaxy LEDA 857074, located in the constellation Eridanus. LEDA 857074 is a barred spiral galaxy, with partially broken spiral arms. It also has a particularly bright spot right in its bar: this is a supernova snapped by Hubble, named SN 2022ADQZ, and quite relevant to this Picture of the Week.
The NASA/ESA Hubble Space Telescope has observed a vast range of celestial objects, from galaxies, to nebulae, to star clusters, to planets in the Solar System and beyond. Observing programmes usually seek to gather data so that astronomers can answer a specific question. Naturally, this means most scheduled observations target an object that astronomers have already researched. Some are famous, like the Crab Nebula or the globular cluster Omega Centauri; others might not be so well known to the public, but still be featured in hundreds of scientific papers, such as the Spider Galaxy or NGC 4753. Not so with this galaxy: LEDA 857074 is named in fewer than five papers, one of which is the Lyon-Meudon Extragalactic Database itself. Virtually no data have been recorded about it, other than its position: since its discovery, it simply hasn’t been studied. So how did it attract the gaze of the legendary Hubble?
The supernova is the answer — SN 2022ADQZ was detected by an automated survey in late 2022, and led to Hubble being pointed at its host galaxy, LEDA 857074, in early 2023. Astronomers have catalogued millions of galaxies, so while today tens of thousands of supernovae are detected annually, the chance that one is spotted in any particular galaxy is slim. We also do not know how actively LEDA 857074 is forming stars, and therefore how often it might host a supernova. This galaxy is therefore an unlikely and lucky target of Hubble, thanks to this supernova shining a spotlight on it! It now joins the ranks of many more famous celestial objects, with its own Hubble image.
[Image Description: A close-in view of a barred spiral galaxy. The bright, glowing bar crosses the centre of the galaxy, with blurred spiral arms curving away from its ends and continuing out of view. It’s surrounded by bright points of light that indicate stars and galaxies. The galaxy also hosts a bright supernova in its central bar.]

I was wondering why there was so many photographers and birdwatchers with their spotting scopes hanging around the lake.
It was this punky/funky red-eye ninja-style fellow creating a stir. Though somehow common in Sweden, a rare sight in Denmark in its summer breeding plumage. Apparently it had been hanging out in my little local "pond" for the last three weeks, and was joined by another one a few days ago.
