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.
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.”
It was the first time a US president had been convicted of or charged with a criminal offence.
Trump had tried to cover up “hush money” payments to a porn star in the days before the 2016 election.
When Stormy Daniels‘ claimsof a sexual liaison threatened to upend his presidential campaign, Trump directed his lawyer to pay $130,000 (£102,000) to keep her quiet.
The payment buried the story and he later won the presidency.
Trump denied the charges and said the case was politically motivated. He also denied the sexual encounter took place.
New York State Supreme Court Justice Juan Merchan today delayed the sentencing, which had been due to take place on Tuesday.

The office of district attorney Alvin Bragg had asked the judge to postpone all proceedings until Trump finishes his four-year presidency, which starts on 20 January.
Trump’s lawyers say the case should be dismissed because it will create “unconstitutional impediments” to his ability to govern.
Responding to Friday’s decision, a Trump campaign spokesman said: “The American People have issued a mandate to return him to office and dispose of all remnants of the Witch Hunt cases.”
The judge set a 2 December deadline for Trump’s lawyers to file their motion, while prosecutors have until 9 December to respond.
He did not set a new date for sentencing or indicate when he would rule on any motion to throw out the case.
Even before Trump’s win in this month’s election, experts said a jail term was unlikely and a fine or probation more probable.
But his resounding victory over Kamala Harris made the prospect of time behind bars or probation even less likely.
Trump, 78, was also charged last year in three other cases.
One involved him keeping classified documents after he left office and the other two centre on alleged efforts to overturn his 2020 election loss.
A Florida judge dismissed the documents case in July, the Georgia election case is in limbo, and the Justice Department is expected to wind down the federal election case as it has a policy of not prosecuting a sitting president.
Trump last week nominated his lawyers in the hush money case, Todd Blanche and Emil Bove, for senior roles in the Justice department.
When he re-enters the White House, Trump will also have the power to shut down the Georgia and New York cases.
Donald Trump has pledged for years to surround himself with ultra-loyalists who can mould his government to his vision without barriers.
That’s precisely why he picked Matt Gaetz. Now he’s out, Pam Bondi is in and she’s equally loyal.
Gaetz was uniquely unpopular on Capitol Hill but ultra-MAGA and ultra-loyal to the president-elect.
He was chosen by the president-elect to do his bidding inside the Justice Department as attorney general.
Critics called his pick “a red alert moment for democracy” and the man a “gonzo agent of chaos” – language that would surely only affirm Trump’s decision in his own proudly disruptive mind.
If it wasn’t for the fact that the president-elect is himself a convicted felon, and a man found liable in a civil court of his own sexual offences, the prospect of Gaetz, with all his baggage, making it through the nomination process would have seemed remote.
But Donald Trump’s return to the White House suggested anything is possible.
And so, beyond his loyalty, Gaetz was Trump’s test for his foot soldiers on Capitol Hill. How loyal were they? Would they wave through anyone he appointed?
It turns out that Gaetz, and the storm around his private life, was too much for a proportion of them.

At least five Senate Republicans were flatly against Matt Gaetz’s confirmation. We understand that they communicated to other senators and those close to Trump that they were unlikely to be swayed.
They included the Republican old guard like Senator Mitch McConnell.
Beyond the hard “no” senators, there were between 20 and 30 other Republicans who were very uncomfortable about having to vote for Gaetz on the Senate floor.

Trump pick Matt Gaetz withdraws
The key question is whether Gaetz was Trump’s intentional wild card crazy choice that he knew, deep down, would probably never fly.
Was Gaetz the candidate he had accepted would be vetoed by senators – who would then feel compelled to wave the rest of his nominees through?
Will Pete Hegseth’s alleged sexual impropriety concern them as they consider the suitability of the former Fox News host and army major to run the Department of Defence?
What about Tulsi Gabbard, the candidate Russian state TV calls ‘our girl’, and the appropriateness of her running America’s intelligence agencies?
These are all appointments that the politicians on Capitol Hill must consider and confirm in the weeks ahead.
We don’t yet know who Trump will choose to direct the FBI.
There are some names being floated which will make the establishment of Washington shudder but then that’s precisely why Trump was elected. He is the disrupter. He said so at every rally, on repeat.
He was quick to pivot to another name to replace Gaetz.
Bondi is the former attorney general of Florida. Professionally she is in a different league to Gaetz. She’s been a tough prosecutor, with a no-nonsense reputation.
She is also among the most loyal of loyalists. Her attachment to Trump stretches way back.
I first came across her in Philadelphia in November 2020 when she was among Trump surrogates claiming the election back then had been stolen from them by Joe Bidenand the Democrats.
She was a key proponent of the false claims the election had been rigged and Trump was the rightful winner.
The court cases concluding that was all nonsense didn’t seem to convince her.
Now she is poised to head up the Department of Justice as the country’s top law enforcement official.
Within hours of taking office, president-elect Donald Trump plans to begin rolling out policies including large-scale deportations, according to his transition team.
Sky News partner network NBC News has spoken with more than half a dozen people familiar with the executive orders that his team plans to enact.
One campaign official said changes are expected at a pace that is “like nothing you’ve seen in history”, to signal a dramatic break from President Joe Biden’s administration.
Mr Trump is preparing on day one to overturn specific policies put in place by Mr Biden. Among the measures, reported by sources close to the transition team, are:
• The speedy and large-scale deportations of illegal immigrants
• Ending travel reimbursement for military members seeking abortion care
• Restricting transgender service members’ access to gender-affirming care

But much of the first day is likely to focus on stopping illegal immigration – the centrepiece of Trump’s candidacy. He is expected to sign up to five executive orders aimed at dealing with that issue alone after he is sworn in on 20 January.
“There will without question be a lot of movement quickly, likely day one, on the immigration front,” a top Trump ally said.

“There will be a push to make a huge early show and assert himself to show his campaign promises were not hollow.”

Donald Trump ally Matt Gaetz has withdrawn his name from consideration to be the next US attorney general.
But Mr Trump’s campaign pledges also could be difficult to implement.
Deporting people on the scale he wants will be a logistical challenge that could take years. Questions also remain about promised tax cuts.
Meanwhile, his pledge to end the war between Russia and Ukraine in just 24 hours would be near impossible.
Even so, advisers based at Mr Trump’s Mar-a-Lago resort or at nearby offices in West Palm Beach, Florida, are reportedly strategising about ending the wars in Ukraine and the Middle East.
Following his decisive victory on 5 November, the president-elect has moved swiftly to build a cabinet and senior White House team.
As of Thursday, he had selected more than 30 people for senior positions in his administration, compared with just three at a similar point in his 2016 transition.
Stephen Moore, a senior economic adviser in Mr Trump’s campaign, told NBC News: “The thing to realise is Trump is no dummy.
“He knows he’s got two to three years at most to get anything done. And then he becomes a lame duck and we start talking about [the presidential election in] 2028.”
