We have loaded up the 11 inch reflector (a Celestron) telescope for the next half of our vacation!

"A number of #Arizona communities are considered Dark Sky cities — including Flagstaff, Fountain Hills and Sedona. DarkSky International is also based in Tucson. Some tribal communities also take their dark skies very seriously." (via @kjzzphoenix)
"While astronomers have raised concerns about all #satellites, experts have warned that #ASTSpaceMobile ’s technology is particularly harmful because of the size of its #spacecraft. The company’s next generation of satellites covers up to 2,400 sq ft – equivalent to the size of a tennis court. ... Researchers have found that the Texas-based company’s BlueWalker 3 satellites are among the brightest objects in the sky."

Accidentally caught some aurora last night after surfacing to a beautiful starry sky from a night dive 🌌🤩

I'm up in the Canadian (telescope) wilderness, wild telescopes abound! I am doing the astronomer in residence blog this week too, so feel free to tune in for some extra #darkskies #astronomy goodness from Killarney Provincial Park!

Solnedgangen var som sædvanlig spektakulær på #Høvblege på #Højemøn. Vi var en del lokale og turister der blev hængende bagefter, for at se den annoncerede #blodmåne. Vi blev enige om at solnedgangen alligevel var den flotteste, selv om månen nu også blev ganske fin i slutningen af formørkelsen.

Will #Musk’s #Starlink satellites lead to #KesslerSyndrome?
#SpaceWeather poses a tremendous threat to all satellites, knocking all computer systems offline. Is that a recipe for Kessler syndrome?
"Over the past 4 years, the number of active satellites in #LowEarthOrbit have increased by several thousand, with tens of thousands more planned in the coming years. The ultimate nightmare is that we’ll experience Kessler syndrome: where a runaway chain reaction of collisions litters low-Earth orbit with millions of pieces of debris, making new launches all but impossible. Currently, Starlink satellites avoid collisions through on-board #AI software that tells them how to move. If that software gets knocked offline, such as by space weather, we have no protections against this catastrophe."

"Warmer coloured LED streetlights that can be dimmed, are part of modernisation plans that would lower energy use as well as reduce light pollution, a council has said."
El ayuntamiento de Córdoba (España) intenta hacer una reforma de alumbrado que ignora, cuando no contradice el reglamento de contaminación lumínica aprobado hace poco para toda Andalucía por su mismo partido político. La asociación local de astronomía amater, Agrupación Astronómica de Córdoba, paraliza el proyecto. Democracia en marcha. La incompetencia política pone en riesgo una subvención federal de maś de cuatro millones de euros. https://www.astrocordoba.es/comunicado-de-la-agrupacion-astronomica-de-cordoba-aac-con-motivo-de-la-renovacion-de-alumbrado-exterior-anunciada-por-el-ayuntamiento-de-cordoba/ #contaminacionluminica, #cielooscuro, #lightpollution, #darkskies
Big Picture Science for Aug. 25, 2025: Don’t Lighten Up
REPEAT
A canopy of stars in the night sky is more than breathtaking. Starlight is also an important tool that astronomers use to study our universe. But the growth of artificial light and light pollution are creating dramatic changes to the nighttime environment. Let your eyes adjust to the dark as we travel to a dark sky reserve to gaze upon an increasingly rare view of the Milky Way and explore what we lose when darkness disappears.
Guests:
* Kim Arcand – Visualization scientist & emerging tech lead, NASA's Chandra X-ray Observatory and author of “Light: The Visible Spectrum and Beyond".
* Don Jolley – Teacher of Math and Sciences at the Bolinas School in Marin, California who has been leading dark sky tours for three decades.
* Christopher Kyba – Interdisciplinary Geographic Information Sciences Research Fellow at Ruhr University Bochum.

“On National Space Day 2025, Hon. Chief Minister of #Maharashtra, Devendra Fadnavis, delivered a historic message: India’s first step toward a State Dark Sky Policy.”
A short poem I wrote not too long ago...
"Starlink so bright,
Now we don't see stars at night."

States demand fiber
Starlink wants billions in grants, but state governments aren’t cooperating
Despite Trump's backing, states aren't giving Starlink the money it demanded.
Jon Brodkin – Aug 21, 2025
"Secretary of Commerce Howard Lutnick told states to 'take a tech-neutral approach' when evaluating Internet providers and to 'provide Internet access for the lowest cost.' The National Telecommunications and Information Administration (NTIA), which is part of the Commerce Department, revised the program rules in a way that made it harder for states to justify spending on fiber networks, despite fiber's clear advantage over satellite in speed and capacity."

Concern as #LightPollution encourages #birds to sing for longer, study finds
22 August 2025
"Birds around the world are singing for nearly an hour longer each day due to light pollution, a new study has shown.
"The research, to be published in the journal Science, used millions of recordings of #birdsong, including from #NewZealand's #NorthIsland.
"President of Birds New Zealand Dr Natalie Forsdick told RNZ more light meant more time for singing, building nests and feeding.
"But she said those things consumed energy and it could be reducing their overall health.
" 'It's just like with humans, if you go to bed a little bit too late, you wake up the next day feeling a little bit the worse for wear. I imagine that birds could feel that same way too, and we certainly see that it disrupts their natural cycles.'
"She said previous studies in New Zealand had shown a range of outcomes, from no effect to increased night-time predation by black-backed gulls on threatened species like banded dotterels.
"But one of the biggest concerns about light pollution in New Zealand was its effect on seabirds.
"Among juveniles, urban light pollution may be mistaken for moonlight, attracting and disorientating species like Cook's #petrel or Hutton's #shearwaters.
"This could cause birds to crash land or collide with buildings, and they may become injured or grounded in cities.
"She said people could help by turning off outside lights when they were not needed, and asking their local councils to consider more directional or dimmer lighting in public places. [I would recommended warmer lighting as well. Too much blue is unnatural!]
"Associate Professor Kristal Cain from the School of Biological Sciences at the University of Auckland said more research was needed to find out how light pollution affected survival and reproduction.
"This paper used bird song data collected by thousands of volunteers globally, and measured when birds started singing in the morning and when they stopped for the night.
"It found that in brighter areas birds started singing early and continued later into the night than in dark areas.
" 'Most of the bird song was collected in #NorthAmerica and #Europe,' Cain said. 'We still need to do similar work in the rest of the world to see how widespread these patterns really are. The manu of #Aotearoa are quite unique in many ways."
" 'Importantly, all this #ArtificialLight is not good for us either.'
"People could do things like closing curtains and planting trees in urban areas to contain some of the light."
