Making do with the tools at hand — Daily Telescope: Seeing stars with an iPhone in the bottom of the Grand Canyon “There I was, flat on my back on a sand berm, with the best camera I had.”
Eric Berger – Dec 8, 2023 1:00 pm UTC Enlarge / Stars over the Grand Canyon.Mitchell Yee reader comments 15 Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We’ll let other publications offer you a daily horoscope. At Ars Technica, we’re going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.
Good morning. It’s December 8, and today’s photo comes from the floor of the Grand Canyon. The photographer, Mitchell Yee, admits that this is not the best shot one might capture from this remote location, but there’s a reasonhe shot it on his iPhone in August.
“While it’s a fairly ordinary photo, what was amazing to me was the level of quality of cell phone photography,” he told me. “Normally, I’d haul out my big Nikon but since we were hiking down to the bottom of the canyon to meet our dories, weight was constrained. So I skipped the extra 1520 pounds of camera, lens(es), and tripod and instead enjoyed the 9-mile hike with my 18-pound pack. Of course, this shot could have been much improved with a ‘real’ camera on a tripod. But there I was, flat on my back on a sand berm, with the best camera I had at that moment, my iPhone 13 mini, and I still made the shot I wanted.”
Dories, I’m pretty sure, are boats. But I’m kind of in “Afraid to Ask” Andy territory with that one.
In any case, I thought the photo was lovely, and I appreciate Mitchell sharing it.

Labour will eliminate unauthorised sewage spillages in 10 years, the environment secretary has told Sky News.
Steve Reed also pledged to halve sewage pollution from water companies by 2030 as he announced £104 billion of private investment to help the government do that.
“Over a decade of national renewal, we’ll be able to eliminate unauthorised sewage spillages,” he said.
“But you have to have staging posts along the way, cutting it in half in five years is a dramatic improvement to the problem getting worse and worse and worse every single year.”
He said the water sector is “absolutely broken” and promised to rebuild it and reform it from “top to bottom”.
His earlier pledge to halve sewage pollution from water companies by 2030 is linked to 2024 levels.
The government said it is the first time ministers have set a clear target to reduce sewage pollution and is part of its efforts to respond to record sewage spills and rising water bills.
Ministers are also aiming to cut phosphorus – which causes harmful algae blooms – in half by 2028.

Mr Reed said families had watched rivers, coastlines and lakes “suffer from record levels of pollution”.
“My pledge to you: the government will halve sewage pollution from water companies by the end of the decade,” he added.
Addressing suggestions wealthier families would be charged more for their water, Mr Reed said there are already “social tariffs” and he does not think more needs to be done, as he pointed out there is help for those struggling to pay water bills.
The announcement comes ahead of the publication of the Independent Water Commission’s landmark review into the sector on Monday morning.
The commission was established by the UK and Welsh governments as part of their joint response to failures in the industry, but ministers have already said they’ll stop short of nationalising water companies.
Mr Reed said he is eagerly awaiting the report’s publication and said he would wait to see what author Sir John Cunliffe says about Ofwat, the water regulator, following suggestions the government is considering scrapping it.
On Friday, the Environment Agency published data which showed serious pollution incidents caused by water firms increased by 60% in England last year, compared with 2023.

Why sewage outflows are discharging into rivers
Meanwhile, the watchdog has received a record £189m to support hundreds of enforcement officers for inspections and prosecutions.
“One of the largest infrastructure projects in England’s history will clean up our rivers, lakes and seas for good,” Mr Reed said.
But the Conservatives have accused the Labour government of having so far “simply copied previous Conservative government policy”.
“Labour’s water plans must also include credible proposals to improve the water system’s resilience to droughts, without placing an additional burden on bill payers and taxpayers,” shadow environment secretary Victoria Atkins added.
The Rivers Trust says sewage and wastewater discharges have taken place over the weekend, amid thunderstorms in parts of the UK.
Discharges take place to prevent the system from becoming overwhelmed, with storm overflows used to release extra wastewater and rainwater into rivers and seas.
Water company Southern Water said storm releases are part of the way sewage and drainage systems across the world protect homes, schools and hospitals from flooding.
In a village in Ladakh, there was experienced an eruption in the sky which turned the sky into red and green auroras on May 10, 2024. This has not been seen in the past 10 years. It got triggered by the fiery solar storm, called Coronal Mass Ejections (CMEs) which are magnetised and thrown from the Sun at a million km per hour distance. Such arruptions in masses, triggered by the filament eruptions and solar flames sped to millions of kilometer towards our planet. This kind of rare aura has been ignited from the fiery solar storm.
Indian Scientists Investigate
According to organiser, The indian scientists’ team, led by Dr. Wageesh Mishra, used the data from NASA, ESA and other ground facilities to find this auroral phenomenon at the Indian Astronomical Observatory, by applying the Flux Rope Internal State (FRIS) model in order to broaden the coronograph images. The evolving temperature, magnetic fields and structure of the Coronal Mass Ejections were mapped at the time of interplanetary journey. This is the first global study to chronicle CME thermal dynamics from the Sun to Earth, which is published in Astronomy & Astrophysics.
Unexpected Reheating of CMEs
In contrast to the expectations, the CMEs didn’t cool with their expansion. In fact, they heat up at their midway, absorbing heat and maintaining a constant temperature over time they impact Earth. This thermal restructuring is due to the collision of two CMEs, where the electrons release high temperatures and ions release mixed lower and higher temperatures predominantly.
Magnetic Collision Triggers Lights
Data from NASA’s Wind Spacecraft, when a solar storm reached Earth, shows that the plasma covered Earth in double flux ropes. These are twisted magnetic structures which can trigger potential geomagnetic disturbances. Such an entangled magnetic field brought auroras as far south. i.e. Ladakh, and produces a spectacular light show that was seen by the citizens of that place.
Global Impact and Research Breakthrough
This finding held significant implications for global space weather forecasting and India. Through the understanding of the interaction of CMEs’ thermal and magnetic changes, the scientists could better develop the early-warning systems for power grid issues, navigation outages and satellite disruptions.
