This Picture of the Week shows mushrooms growing atop ESO’s La Silla Observatory, in Chile, bathed in the dim light of the sunset. Wait… these are not mushrooms, but telescopes! To the left stands the Danish 1.54-metre telescope and to the right, the three telescopes of the BlackGEM telescope array.
The Danish 1.54-metre telescope has over 40 years of astronomical research on its shoulders. It observed for the first time the visible light associated with quick energetic events known as short gamma-ray bursts, showing that these explosions likely result from the fusion of two neutron stars. Operated jointly by research groups in Denmark and the Czech Republic, you can see this telescope hard at work every night via its dedicated webcam.
This telescope doesn’t exclusively study these energetic events, but BlackGEM, developed in The Netherlands and Belgium, was specifically designed to do so. When large objects like neutron stars merge, they create waves in the fabric of space-time, much like ripples on a lake. As soon as the rough location of these events has been determined by gravitational wave detectors like LIGO and Virgo, BlackGEM scans the area to hunt for any visible glow that wasn’t there before.
These events are extremely difficult to track and to differentiate from other phenomena across the night sky. For this reason, BlackGEM is using the help of citizens to find real explosions. It may be time to transform your smartphone into a pocket “mushroom” telescope...

This Picture of the Week shows a long exposure image of the BlackGEM telescopes, located at ESO’s La Silla Observatory in Chile. The whitish star trails in the sky are an effect due to the Earth’s rotation on its axis around the southern celestial pole, which gives the impression of the stars’ movement over the course of several hours. To the right hand side of the central telescope the Milky Way is visible, seen here as a particularly bright region, densely packed with streaks of starlight. As these streaks move in circles across the night sky, the viewer gets a sense of tumbling around inside a giant washing machine, as they peer out at the scene through the fisheye lens.
BlackGEM, which recently started operating, is an array of three 0.65-metre optical telescopes, which can point at different regions of the sky, searching for some of the most dramatic events in the Universe like merging neutron stars and black holes. As these events unfold they send out ripples in spacetime, known as gravitational waves, which can be picked up by observatories like LIGO and Virgo. BlackGEM can then pinpoint the light sources from the afterglow of these events, allowing for more detailed follow-up observations of these cataclysmic collisions.

In this Picture of the Week, Venus is shining brightly over ESO’s La Silla Observatory in Chile. The picture was taken just before dawn, towards the East, and also features the diffuse zodiacal light –– sunlight scattered by dust particles in the Solar System.
The three domes to the left of the road are the BlackGEM telescopes, built by Radboud University, the Netherlands Research School for Astronomy (NOVA), and KU Leuven. BlackGEM will search for the afterglow of some of the most dramatic events in the Universe, such as the collision of black holes and neutron stars. The ripples in space and time generated by these violent events can be detected by the LIGO and Virgo observatories. Thanks to their large field of view, the BlackGEM telescopes can locate the source of visible light from the afterglow of these events, and thereby pinpoint where the collision took place. This allows astronomers to study in greater detail what happens when black holes and neutron stars merge.

This striking star trail image was captured above ESO’s La Silla Observatory, in Chile’s Atacama desert. Star trails are caused by Earth’s rotation; in this long exposure image, stars appear to circle around the south celestial pole. Almost unrecognisable are the Carina Nebula (bright magenta smudge, centre-left) and the Large and Small Magellanic Clouds (blue smudges in the centre-top and centre-right, respectively).
Gazing up into the starry vortex are two of the three BlackGEM telescopes, built and operated by Radboud University, the Netherlands Research School for Astronomy (NOVA), and KU Leuven.The third telescope on the right was still under construction at the time this photograph was taken, having only a platform and no dome. BlackGEM eventually aims to expand to 15 telescopes, capable of performing extensive surveys of the night sky.
BlackGEM will join detectors such as LIGO and Virgo in the search for the most dramatic events in space, such as merging black holes and neutron stars. Following the detection of gravitational waves from these collisions by LIGO and Virgo, BlackGEM will scan large areas of the sky looking for the visible light emitted in these events. Other facilities like ESO’s Very Large Telescope will then follow up on BlackGEM’s measurements, enabling astronomers to better understand some of our universe’s most elusive phenomena.

A small step is being taken up the stairs to one of the BlackGEM telescopes in this Picture of the Week, but this facility represents a giant leap in gravitational wave studies at ESO’s La Silla Observatory in Chile. BlackGEM — which was developed by Radboud University, the Netherlands Research School for Astronomy, and the KU Leuven and officially inaugurated in January 2024 — is a mostly robotic array of optical telescopes designed to scan the southern sky.
Each telescope in the array is aimed at different parts of the clear sky above La Silla, ever ready to detect the visible light afterglow of gravitational wave sources — cataclysmic events such as merging neutron stars or black holes. BlackGEM will pinpoint where these sources are and provide astronomers with a target for follow-up observations with other, larger telescopes to learn more about them.
From the southern hemisphere, astronomers also have a pristine view of the Milky Way and our neighbour galaxies, the Magellanic Clouds, seen here in their characteristic wispy and cloud-like shape. In the Mapuche culture of south-central Chile, these clouds are known as lafken, labken or künchalabken (“the lagoons”) as well as rünanko (“the water wells”).

This family portrait of the telescopes residing at ESO’s La Silla Observatory was captured in 2019 during the breathtaking sunset over the outskirts of Chilean Atacama Desert.
Standing tall at the front of the portrait is one of La Silla’s new family members: BlackGEM, an array of optical telescopes which will join soon the search for some of the most powerful and dramatic events in the Universe, such as merging neutron stars and black holes. This robotic array was developed by Radboud University (from where it is remotely controlled), the Netherlands Research School for Astronomy (NOVA), and the KU Leuven.
These exotic events cause ripples in the fabric of spacetime known as gravitational waves. BlackGEM will work together with gravitational wave detectors such as LIGO and Virgo to pinpoint in visible light the sources responsible for gravitational waves. This will allow for bigger telescopes — such as ESO’s Very Large Telescope (VLT) — to carry out detailed follow-up observations. This will provide astronomers with insight into some of the most extreme events in the universe and help unveil the mysteries of the cosmos.

From the long eastward shadows of the telescopes in this Picture of the Week we can see that it’s almost the beginning of a long night shift of stargazing for the telescopes at ESO’s La Silla Observatory. In the foreground of this picture is the BlackGEM array, designed to hunt for the visible light of gravitational wave sources. If you then follow the road up to the summit of La Silla you will pass several ESO telescopes including the 1-metre Schmidt telescope and the New Technology Telescope, until you finally reach the 3.6-metre telescope at the top, home to the HARPS planet hunter.
La Silla mountain is ideally situated for an observatory as its isolated location means there is very little light pollution. It is also in Chile’s extremely dry Atacama desert at an altitude of 2400 metres, meaning there’s hardly ever a cloud in the sky and almost every day boasts clear blue skies as can be seen in this picture.

The white pearl on the left side of this Picture of the Week is one of the Exoplanets in Transits and their Atmospheres telescopes — ExTrA for short. Located at ESO’s La Silla Observatory at an altitude of 2375m, ExTrA is a French national project comprising three 60 centimetre telescopes that are working towards one goal: to detect Earth-sized planets in our home galaxy, the Milky Way.
ExTrA focuses on planets around very small stars, with a radius down to a tenth of the Sun. It relies on the so-called transit method, looking for slight dips in the light emitted from a star when a planet passes in front of it, like a tiny eclipse. The smaller the star is, the larger the dip an Earth-sized planet will cause. Each telescope observes a target star and four reference ones to calibrate the effects of Earth’s atmosphere. The telescopes can observe either the same patch of the sky or different ones; the light they collect is sent to a single infrared spectrograph that breaks it up into different colours or wavelengths, thus combining the classic transit method with spectral information.
Not only do ExTra telescopes make great exoplanet hunters, they also make pretty good picture frames. Just kidding, but can you see the telescope peaking through the frame of the door of the dome? It’s the ESO 3.6-metre telescope. Also, ExTrA are not the only triplets at La Silla: in this image we can also see the three BlackGEM telescopes.

The three BlackGEM telescopes seen at the centre of this Picture of the Week, hosted at ESO’s La Silla Observatory in the Chilean Atacama Desert, are searching for the stuff that jewelry is made of. Developed by Radboud University, the Netherlands Research School for Astronomy, and KU Leuven, BlackGEM scans the sky looking for some of the most dramatic explosions in the Universe.
When black holes or neutron stars merge with each other they create ripples in space-time called gravitational waves. These waves can be detected with sensitive facilities like LIGO or Virgo, but what if we could study the actual merger event in even more detail? BlackGEM can home in on the location of a merger by probing large areas of the sky in visible light, looking for the faint afterglow that may result from these cosmic collisions.
When BlackGEM has found one of these sources, the true treasure hunt begins. These mergers are the factories of the heaviest elements in the universe, such as silver, gold and platinum: the jewels of the Universe. With larger optical telescopes, such as ESO’s Very Large Telescope further north in Chile, extremely detailed studies of the sources found by BlackGEM can be made, enabling astronomers to get a glimpse into how the heaviest elements are created.

From the last game of Erick's fall soccer season. I'm not sure why the ref decided to stand stock still while the two teams changed players, but I love the feeling of calm in the middle of a storm.
At the centre of this Picture of the Week shows are the three telescopes of the BlackGEM array, located in ESO’s La Silla Observatory. BlackGEM is looking for the most intense events in the Universe: the origins of gravitational waves.
Different mechanisms can produce these ripples in space-time. For instance, two neutron stars — the collapsed cores of massive stars — can merge in violent spirals, spinning thousands of times per second and emitting powerful signals. In the chaos, precious metals are born into the Universe and colossal magnetic fields cause immense but short bursts of gamma rays.
Back on Earth, the LIGO and Virgo gravitational wave detectors can only roughly estimate where these waves may originate. Enter BlackGEM, which quickly scours the target area of the sky with incredible sensitivity to spot the optical light emitted in these events. This allows astronomers to pinpoint their location and study them in more detail with larger telescopes.
But there is still much to learn about these events. Merging black holes, for example, do not release electromagnetic waves, but would also be visible to BlackGEM when sat in dense regions where they illuminate the matter around them. BlackGEM will therefore be vital to make the first optical observations of these mergers, and establish the environments black holes may form in.

I was asked just this morning to make another baby card.
This is it.
A stamping up acrylic set used to stamp the bears. Then scanned into my computer and the size of the bears changed and coloured.
Fussy cut...black gems for eyes and nose.
Stuck onto embossed white card....bordered in Matt gold.....and then onto striped card.
The sentiments are from the same stamp set.
The baby bear is a boy.

Gawd, I really love this headpiece!!!
This aloes turn back to green when I bring them indoor in winter and change to almost black- dark color when they stay outside in spring-summer with adequate exposure to sun.
“You may write me down in history
With your bitter twisted lies
You may trod me into the very dirt
But still like dust, I will rise
You may shoot me with your words
You may cut me down with your eyes
You may kill me with your hatefulness
But still like Air I will rise”

Pictured -- a very scenic road to the stars. The road approaches La Silla Observatory in Chile, with the ESO's 3.6-meter telescope just up ahead. To the left are some futuristic-looking support structures for the planned BlackGEM telescopes, an array of optical telescopes that will help locate optical counterparts to gravitational waves detections by LIGO and other detectors. But there is much more. Red airglow illuminates the night sky on the right, while the central band of our Milky Way Galaxy slants across the image center. Jupiter can be seen just above the band near the image center, while Saturn is visible just above the 3.6-meter telescope dome. The two largest satellite galaxies of our Milky Way Galaxy, the LMC and SMC, are seen on the far right. The featured image panorama was built up from multiple 15-second exposures that were captured on 2019 June 30. Two days later, La Silla experienced a rare total eclipse of the Sun. via NASA
