Stars are disappearing before our eyes at a faster rate than originally thought, with almost a third of people around the world now unable to see any at all, according to new research.

While the unaided human eye should be able to spot several thousand stars on a clear, dark night, our view of our home galaxy – the Milky Way – and dozens of intricate constellations is rapidly being lost.

Due to light pollution, it is estimated that 30% of people worldwide have been robbed of their nightly view.

The startling figure comes via analysis from a citizen science programme called Globe at Night, which published its findings in the journal Science.

NOIRLab, a US research centre for nighttime astronomy, runs the study, which projects that a child born today in a place where 250 stars are visible would only be able to see 100 by the time they turn 18.

Astronomer Connie Walker said the findings underscore “the importance of redoubling our efforts” to protect the nighttime sky from a phenomenon dubbed “sky glow”.

What is sky glow?

Sky glow refers to the illumination of the night sky beyond that caused by natural sources, like stars or the moon.

It has long been known to be a problem, but Globe at Night’s observations suggest it is increasing far more quickly than shown in satellite measurements of the Earth’s brightness at night.

The study is based on crowdsourced reports from all over the world, with people submitting their findings online.

They are then shown a number of star maps and record which one best matches what they can see in the sky, providing an estimate of what’s known as “the naked eye limiting magnitude”.

This is a measure of how bright an object must be in order to be seen, and estimates the brightness of sky glow.

Globe at Night’s findings are based on more than 50,000 observations submitted from Europe and North America between 2011 and 2022.

Why should we be concerned?

Light pollution doesn’t just spoil the view of the sky, it can also impact our health – and that of wildlife.

This is because it disrupts the natural cyclical transition from sunlight to starlight that we and other organisms have evolved alongside – and sky glow is anything but natural.

Humans have generally had an awe-inspiring view of the starry night sky throughout history, but the path we are on now means that an ever-increasing number of people are losing out.

The loss of visible stars reported by Globe at Night indicates an increase in sky brightness of 9.6% per year over the past decade, much more than the 2% measured by satellites.

“This shows that existing satellites aren’t sufficient to study how Earth’s night is changing,” said study lead author Christopher Kyba, of the German Research Centre for Geosciences.

And while the new findings are focused on the western world, the paper notes that the sky is likely brightening more quickly in developing countries, where the prevalence of artificial lighting is growing at a higher rate.

“The increase in sky glow over the past decade underscores the importance of redoubling our efforts and developing new strategies to protect dark skies,” said Connie Walker.

“The Globe at Night dataset is indispensable in our ongoing evaluation of changes in sky glow, and we encourage everyone who can to get involved to help protect the starry night sky.”

US blocks Palestinian President Mahmoud Abbas and 80 other officials from United Nations’ annual meeting in New York

US blocks Palestinian President Mahmoud Abbas and 80 other officials from United Nations' annual meeting in New York

Palestinian President Mahmoud Abbas and 80 other officials have been blocked from attending September’s annual meeting of the United Nations General Assembly in New York.

US secretary of state Marco Rubio has revoked the US visas of delegates from the Palestinian Authority (PA) and Palestine Liberation Organisation (PLO), and denied others from applying for one.

It is the latest step by Donald Trump’s administration to target Palestinians with visa restrictions, and follows the suspension of a programme to allow injured children from Gaza to receive treatment in the US.

“It is in our national security interests to hold the PLO and PA accountable for not complying with their commitments, and for undermining the prospects for peace,” a statement from the US State Department said.

It added that, to be considered partners for peace, both groups “must consistently repudiate terrorism, and end incitement to terrorism in education, as required by US law and as promised by the PLO”.

Offensive will cause ‘intolerable deaths’

Several US allies, including France, Malta, and Australia have announced plans to recognise Palestine as a state at September’s United Nations General Assembly. Canada and the UK will too, unless Israel meets certain conditions.

The Palestinian ambassador to the United Nations (UN), Riyad Mansour, said Mr Abbas had planned to lead the delegation to the UN meetings and was expected to address the general assembly at the general debate, which begins on 23 September.

He was also expected to attend a high-level meeting co-chaired by France and Saudi Arabia on 22 September about a two-state solution, a broad idea involving Israel coexisting with an independent Palestinian state.

The State of Palestine is an observer member of the UN, meaning it can speak at meetings but not vote on resolutions.

US decision ‘contravenes international law’

The Palestinian Authority “expressed its deep regret and astonishment” at the visa decision, calling it “a violation of US commitments” as the host of the UN, and claiming it “contravenes international law”.

UN spokesman Stephane Dujarric said the world body would be seeking clarification in the “hope that this will be resolved”.

The State Department said that the Palestinian Authority’s mission to the UN, comprising officials who are permanently based there, would not be included in the restrictions.

Under a 1947 UN agreement, the US is generally required to allow access for foreign diplomats to the UN in New York.

But Washington has said it can deny visas for security, extremism and foreign policy reasons.

The death toll in Gaza has now risen to 63,025, according to the Hamas-run health ministry, which does not differentiate between civilians and combatants.

It also reported five more malnutrition-related deaths in the last 24 hours, bringing the total number during the war to 322, with 121 of them children.

Donald Trump revokes Secret Service protection for former vice president Kamala Harris

US President Donald Trump has revoked Secret Service protection for former vice president and 2024 Democratic rival Kamala Harris.

A senior adviser to Harris, Kirsten Allen, confirmed the decision. “The vice president is grateful to the United States Secret Service for their professionalism, dedication, and unwavering commitment to safety,” said the adviser.

Typically, vice presidents receive a six-month security detail from the Secret Service after they leave office, although it had been extended to 18 months for Harris, according to officials.

Initially, then-president Joe Biden extended her security arrangements to one year, or January 2026, according to reports.

However, a Secret Service official told Sky News’ US partner, NBC, that Biden subsequently signed an executive memorandum in January increasing the then vice-president’s protection period even further, to 18 months.

Former US presidents receive Secret Service protection for life.

Harris, who lost the 2024 presidential election to Mr Trump, is due to start a book tour for her memoir, “107 Days”, shortly.

She was the Democratic nominee for 107 days after Biden exited the race in the weeks following a challenging debate against Trump.

Mr Trump has also ended federal security protection for others, including former national security adviser John Bolton. Last week, FBI agents raided Bolton’s Maryland home.

In March, the president ended protection for Joe Biden’s children – Hunter and Ashley Biden.

Harris has not ruled out a possible presidential run in 2028. She announced in July that she would not run for governor of California in 2026.

Boy, 8, and girl, 10, killed in US Catholic school shooting named - as father brands attacker 'a coward'

The families of two children killed in the US Catholic school shooting have said their “hearts are broken” and branded the attacker a “coward”.

Fletcher Merkel who was eight and 10-year-old Harper Moyski were killed during mass at Annunciation Catholic School in Minneapolis on Wednesday.

Eighteen other people were injured, including children aged between six and 15 and three adults in their 80s.

Police said Robin Westman, a male born as Robert Westman, opened fire with a rifle through the windows of the school’s church as children sat in pews.

New details released of US school shooting

‘Our hearts are broken’

Harper’s parents, Michael Moyski and Jackie Flavin, remembered her as “a bright, joyful, and deeply loved 10-year-old whose laughter, kindness, and spirit touched everyone who knew her”.

“Our hearts are broken not only as parents, but also for Harper’s sister, who adored her big sister and is grieving an unimaginable loss. As a family, we are shattered, and words cannot capture the depth of our pain,” their statement said.

They urged leaders and communities to “take meaningful steps to address gun violence and the mental health crisis in this country.”

“Change is possible, and it is necessary – so that Harper’s story does not become yet another in a long line of tragedies,” the statement added.

‘Fletcher loved his family’

In a statement reported by Sky’s US partner network NBC News, Fletcher’s father Jesse Merkel blamed the “coward” killer for why the boy’s family can’t “hold him, talk to him, play with him, and watch him grow into the wonderful young man he was on the path to becoming”.

He said: “Fletcher loved his family, friends, fishing, cooking, and any sports that he was allowed to play.

“While the hole in our hearts and lives will never be filled, I hope that in time, our family can find healing.”

Mr Merkel also praised “the swift and heroic actions of children and adults alike from inside the church”.

“Without these people and their selfless actions, this could have been a tragedy of many magnitudes more. For these people, I am thankful,” he added.

Mayor calls for assault weapon ban

It comes after Minneapolis mayor Jacob Frey called for a statewide and federal ban on assault weapons, a day after the deadly school shooting.

Minneapolis mayor urges assault weapons ban

“Thoughts and prayers are not going to cut it. It’s on all of us to see this through,” the mayor said at a news conference. “We need a statewide and a federal ban on assault weapons.

“We need a statewide and a federal ban on high-capacity magazines. There is no reason that someone should be able to reel off 30 shots before they even have to reload.

“We’re not talking about your father’s hunting rifle gear. We’re talking about guns that are built to pierce armour and kill people.”

Meanwhile, Minneapolis police chief Brian O’Hara gave an update on the investigation, saying the suspect had fired 116 rifle rounds into the church.

“It is very clear that this shooter had the intention to terrorise those innocent children,” he added, before saying the killer “fantasised” about the plans of other mass shooting attackers and wanted to “obtain notoriety”.
