Some of the many #observatories at Cerro-Tololo in Chile when we visited in 2019.

We're on a paved plateau high up in the mountains under a sky of blindingly bright, vibrant blue. Our view to the distant peaks of the dry mountain ranges is blocked by four large structures here. Three of them are observatories: white block buildings topped with domes, each with a thick ridge on its curved surface indicating where it can be opened after rotation for viewing purposes. The observatories on the right and in the centre are the larger two and can be fully seen while the one to the left is smaller and behind two large shipping containers, only its dome peeking out over the top. Leftmost of all is a smaller observatory structure just in front of the containers, shaped like a large 20-sided die mounted on a platform reached by a ladder. It feels quiet and cool here.

From blurry to breathtaking: Comparing three views of the Carina Nebula. La Silla, Hubble, and James Webb show this cosmic landscape in ever greater clarity, illustrating how advances in telescope technology are transforming our vision of the universe and revealing its hidden structures.

Three vertically stacked astronomical photographs compare the same section of The Carina Nebula (catalogued as NGC 3372), each labeled with the telescope or observatory that captured it.

Top: Labeled "La Silla Observatory," the nebula appears in muted brownish-orange tones, with many stars visible but slightly blurred. A red rectangle highlights a small protruding formation at the nebula’s edge, and a zoomed-in circular inset to the right shows this area with low detail and a soft, hazy outline.

Middle: Labeled "Hubble Telescope," the nebula displays more vivid colors, including blues, purples, and reds. The same protruding formation is highlighted by a red rectangle, and the zoomed-in inset shows more distinct edges and texture compared to the La Silla image.

Bottom: Labeled "James Webb," the nebula appears in sharper detail with golden-brown ridges against a deep blue star-filled background. The same protrusion is marked with a red rectangle, and the zoomed-in inset shows the most clarity, revealing fine structure and a greater number of small stars in the background.

Threats to astronomical observatory sites around the world from light pollution are growing, but the existing skyglow standard for site protection dates to nearly a half-century ago. Astronomers are considering a new standard to replace it given advances in lighting technology.

Read more about what's at stake for astronomy and how this effort developed: http://www.darkskyconsulting.com/blog/toward-a-new-standard-for-astronomical-observatory-site-protection

The light pollution of Tucson, Arizona can be seen in the backdrop of this photo of Kitt Peak National Observatory, with the Nicholas U. Mayall 4-meter Telescope featured prominently. In addition to being an aesthetic blight, light pollution poses one of the greatest risks to astronomical research at Kitt Peak, drowning out the natural starlight and the light from distant asteroids, comets, galaxies, quasars, and other objects in the night sky.

The International Astronomical Union notes the need to update the 1980 joint CIE-IAU light pollution metric for astronomical observatory sites and "is currently considering drafting a resolution based on these recommendations to be submitted for approval at its next general assembly in 2027."

🎙️ ✨ The Art of Being Random – Ravioli in London, Unscripted Conversations, and Writing Magical Short Stories

One moment, we’re talking about hats. The next, it's #London's skyline, ravioli, and why my mom—at 70+—decided to start writing magical short stories for kids and the young at heart.

Welcome to Random and Unscripted #Podcast, where Sean Martin and I embrace the art of wandering conversations.

In this episode, we explore #creativity, #storytelling, and why the best ideas often come from unexpected places.

Storie Sotto Le Stelle started as a small project—just a few whimsical tales blending #Tuscan nostalgia with fantasy. Now, it’s a growing collection of stories where enchanted gardens, talking animals, and #AI #Robots ran #observatories all coexist.

What does it take to be creative? A little madness, a lot of curiosity, and, apparently, a habit of talking to imaginary friends.

"The industrial #megaproject is planned to be located just 5 to 11 kilometres from telescopes at Paranal, which would cause irreparable damage to astronomical observations, in particular due to light pollution emitted throughout the project’s operational life. Relocating the complex would save one of Earth's last truly pristine dark skies." (via @esoastronomy)

LOOK!

These odd plots represent the first data from the SKA-low telescope working as an interferometer.

Data comes from two stations (each with 256 antennas) where the signal is correlated. That little kink is the radio galaxy Centaurus A.

SKA is starting to come online!

SKA-low features these odd-looking antennas that resemble Christmas trees. 256 of them sit in a ‘station’ which acts as a single unit. Once construction is complete (end of decade) there will be 512 stations separated by distance creating a large virtual telescope.

SKA-low is the Australian side of the project and will feature over 131,000 antennas to cover the low-frequency bands.

This will complement SKA-mid, located in South Africa which will have an interferometer made of dish antennas and cove a huge bandwidth up to 15 GHz.

Plot showing frequency in the x-axis and time on the y-axis. The data presented is the correlated signal of a polarisation parameter between two SKA-low stations. It looks like several wavefronts that are almost parallel and diagonally leaning.

Plot showing frequency on x-axis and phase on y-axis. The data points form several almost straight lines starting from top left or bottom right. Three of the middle lines have a link in them which is representative of an interesting radio object in the telescope beam.

“EPOCH MARKING”
THE CITY TELESCOPE
OBSERVATORY AT KELBURN
THE OPENING CEREMONY
The City Council’s nine-inch astronomical telescope, which has been installed in a temporary building in the grounds of the Observatory at #Kelburn, was officially opened yesterday afternoon by the Mayor, Mr. R. A. Wright, M.P. Interesting addresses were delivered on the occasion.
The Mayor said he was very pleased to see so many citizens assembled at the opening of the observatory. Wellington was the first municipality in the Dominion that had extended its activities to the realm of astronomical science, in the purchase and setting up of a telescope.…
…
Councillor W. H. Bennett expressed the opinion that the event they were taking part in that day was a sign of the progress of the city—a milestone in Wellington’s journey to becoming one of the chief cities of the Southern Hemisphere.
The Mayor then formally declared the observatory open, and the visitors spent some time in inspecting the new city telescope.

VIEWS OF MARS
SIGHTSEERS AT ROSLYN
AIR IN POOR CONDITION
(BY TELEGRAPH.—SPECIAL TO THE POST.)
DUNEDIN, This Day.
Fully 200 persons went to #Roslyn Observatory on Saturday evening in the hope of viewing #Mars through the 12in telescope of the Otago Institute. The sky was quite clear, but a wavy current in the atmosphere made visibility poor. Nevertheless, the Roslyn instrument enabled visitors to see the glint of the south polar snowcap and shaded markings. “We have seen no traces of straight lines, corresponding to the so-called canals,” states a local authority, “but it was scarcely to be expected that we should see them under the conditions of our observation. The observations of these canals are erratic. In some cases small telescopes have been more successful than larger ones. It is difficult to say what are the conditions under which the canals can be best seen. Our conditions cannot be compared, for example, to the conditions in Arizona, but that is no fault of the telescope. The fact that we are not seeing the canals is no argument that they do not exist.”
