How and where to see Perseid meteor shower tonight
While about 150 meteors will cross the sky per hour, only up to 100 of them might be visible.
The meteor shower occurs every summer. This year's has already been running for several weeks but is expected to be most visible on Tuesday night.
Where can I see it?
The meteor shower will be visible across all of the UK, but will be most visible in the north-east of the UK as the sun sets.
The further south you go, the lower Perseid sits on the horizon, making the spectacle harder to see.
Experts say stargazers have a better chance of seeing shooting stars in areas with less light pollution.

When and how can I see it?
Once the sun sets, clear skies will afford good visibility on Tuesday night, although a waning full moon might make it brighter than normal and obscure the perfect view.
The meteor shower will be best seen pre-dawn, but can also be visible from late at night.
Find a place well away from street lamps, Dr Bloomer advises. Switch off any house lights if you are looking out from your garden.
Dr Bloomer said you will need to allow time to let your eyes adjust to the dark before the meteor shower could be seen.
He recommended viewers take a camping chair or a rug, sit down outside away from any light source and wait about half an hour.
Shooting stars generally only last a second or two and sometimes appear in flurries.
If you're struggling to see the meteor shower, Dr Bloomer suggested turning your head and watching through peripheral vision (side vision) as it can be easier to see in low light conditions. A meteor streaks across the sky during the annual Perseid meteor shower in 2021. / Credit: NASA
What is a Perseid meteor shower?
Every summer the Earth hits a trail of debris from the Swift-Tuttle comet as it orbits the sun.
Specks as small as a grain of dust flare up under the pressure of the planet's atmosphere and create shooting stars and a long trail of light and colour.
Perseid is considered the best meteor shower of the year and peaks in mid August.
Perseids are also known for their fireballs, which are larger explosions of light and colour and bigger than the average meteor streak.
This meteor shower has already been running for a few weeks and will continue until around August 24.

NASA's nuclear gamble on the moon faces growing skepticism
Fast-tracking a NASA plan to build a nuclear reactor on the moon may sound dubious. Experts say that's because it is. 'The whole proposal is cock-eyed and runs against the sound management of a space program that is now being starved of money,' national security analyst, nuclear expert and author Joseph Cirincione told The Independent. Nuclear has been used in space since the 1960s. That's nothing new. The U.S. launched its first test reactor into orbit in 1965, and the former Soviet Union has sent up dozens more. NASA says that a new 100-kilowatt reactor could be used to power a future base at the lunar South Pole, and fuel prospective missions to Mars and beyond. Nuclear would help to fill gaps in solar energy that occur when that side of the moon is in darkness for two weeks. The majority of space experts have said that placing a reactor on the moon is possible, so, why is NASA's current plan 'cock-eyed?' The problem is the proposed timeline. Interim NASA Administrator Sean Duffy, who also serves as President Donald Trump's Secretary of Transportation, pushed to expedite the project, detailed in a memo this week. Duffy said the administration wanted to have a nuclear reactor ready to launch by 2030. Earlier this year, China and Russia announced a plan to build a nuclear reactor for a lunar base by 2035. 'The first country to do so could potentially declare a 'keep-out' zone which would significantly inhibit the United States from establishing a planned Artemis presence if not there first,' Duffy said. NASA first announced in 2021 that it would put a reactor on the moon 'within a decade.' In 2024, NASA then said that their target date for delivery a reactor to the Earth-based launchpad was the early 2030s. But, Cirincione says essentially no progress has been made. 'It was in the last Trump administration that NASA had put out a press release, they had a YouTube video, they had these announcements about how they're going to develop these small, modular nuclear reactors for use on the moon, and it was going to be ready by 2026,' said Cirincione, who is vice-chair of the Center for International Policy, a non-profit that advocates for a peaceful approach to foreign policy. 'Oh, really? So, where is it?' Ultimately, the expert believes a nuclear reactor on the moon could take up to 20 years to become a reality. NASA would need a working launch vehicle, a small and adaptable reactor, and the ability to land on the moon. Right now, the SpaceX Starship is the only vehicle option – but it has exploded during several of its test flights. NASA has been working with Boeing on a Space Launch System - the main competitor to Space X's Starship - but that program would be canceled under the Trump administration's proposed cuts which slash 24 percent from NASA's overall budget. Landing on the moon is no picnic, and attempts by Japanese space companies in 2023 and 2025 ended in crashes. There are also the scientific and technological advances needed for the nuclear reactors. The reactors must be able to withstand harsh conditions on the moon, including temperatures swings from 250 degrees Fahrenheit during the day to minus 400 degrees at night. 'Small modular nuclear reactors, it turns out, are always just around the corner – a corner you never get to turn,' Cirincione said. Many scientists and nuclear energy experts have shared in Cirincione's skepticism. Dr. Kathryn Huff, a former nuclear energy official at the U.S. Department of Energy, and professor at the University of Illinois at Urbana-Champaign, wrote in a Bluesky social media post that she's not 'bullish' on 'unrealistic timelines.' 'The 2030 target does not align well with recent budgetary trends…' she explained in a statement, shared by the university. 'Accelerating the FSP program could come at the expense of other critical priorities, including earth science, climate observation and space-based weather forecasting – all core elements of NASA's public-serving mission.' Dr. Alfredo Carpineti, an Italian astrophysicist, wrote in IFLScience this week that the proposal is 'unfeasible.' 'Even if we allow landing the nuclear reactor on December 31, 2030, the timing is really too short for something that must not have any faults if you want to operate it safely,' Carpineti wrote. Others were more optimistic about NASA's accelerated timeline. Sebastian Corbisiero, a senior program manager at Idaho National Laboratory who leads the Energy Department's space reactor program, told The Independent that a nuclear reactor on the moon is 'doable' by 2030. 'Nuclear reactor technology has been around for decades, so its well known,' he said. 'Some key differences with a space reactor is that it needs to fit on a rocket, so there are mass and volume requirements; and that the system needs to operate in vacuum – so components will need to be built to survive that environment.' Dr. Bhavya Lal, a former associate administrator for technology, policy, and strategy at NASA, and former aerospace executive Roger Myers, recently argued that it would be possible to have nuclear reactor on the moon by 2030, and it would take $3 billion to do so. 'It's possible, but it will require serious commitment,' Lal told The Independent. But even if plans are speeded up, Lal says there's no need to worry about the prospect of the moon blowing up. It's 'simply not grounded in science,' she said.

Scientists want to send tiny, solar-powered spacecraft to Mars
Scientists want to send tiny, solar-powered spacecraft to examine difficult-to-reach parts of Earth 's atmosphere – and eventually other planets too. The small devices are able to float in the air and could carry sensing instruments to monitor our climate as well as explore Mars, the researchers behind them suggest. Unlike conventional spacecraft, they do not need fuel to stay floating in the atmosphere. Instead, they use energy from light, through a process known as photophoresis that has been used to make objects levitate for 150 years. Despite that long history, the practical use of photophoresis has been limited to truly tiny objects or very powerful artificial light, and practical devices have not worked out. Now, however, researchers believe that they have made a centimetre-long flying device out of perforated sheets that can use natural sunlight to stay afloat. The flying structure is made from two thin, perforated membranes that are attached together by tiny supports. They can be used to create a tiny disc that is then able to leveitate. They could be sent up to the upper layers of the Earth's atmosphere. If they can be scaled up slightly, they would be able to carry antennae and circuits that would allow them to be used to monitor the atmosphere and for other science work. Eventually, the same design could be taken to other planets, they suggest. It is currently almost prohibitively expensive to send satellites to Mars, for instance – but doing so with the tiny spacecraft could allow researchers to monitor conditions on that planet, they say. 'If the full potential of this technology can be realized, swarms or arrays of such photophoretic flyers could be collecting high-resolution data on the temperature, pressure, chemical composition and wind dynamics of the mesosphere within the next decade,' Igor Bargatin from Penn University wrote in an article accompanying the new research.

Blood Moon lunar eclipse: When is it and how can you see it?
A lunar eclipse, also known as a 'Blood Moon', is taking place on 7 September and should be partly visible from the UK. A lunar eclipse is when the Earth is between the Sun and the Moon, meaning the Moon is in the Earth's shadow. When it is a total eclipse the Moon can take on a red/orange colour which is why it is sometimes called a Blood is the second lunar eclipse of 2025. Read on to find out more about what a Blood Moon is and when best to look out for it. What is a Blood Moon lunar eclipse? A Blood Moon or total lunar eclipse happens when the Sun, Earth and Moon are lined up. That means the Earth moves directly in between the Sun and Moon, blocking the sunlight. The Moon then enters the shadow created behind the Earth, creating an the light of the Sun passes through the Earth's atmosphere, the sunlight light is removed leaving only red longer wavelengths to reach the Moon giving it a reddish colour. Unlike a solar eclipse people do not need protective glasses to see a lunar eclipse. How to see the Blood Moon lunar eclipsse? People based in Asia and parts of Australia will get to see the eclipse from start to in Europe and Africa may still see it all as Museums Greenwich advises that in the UK the Moon is due to rise above the horizon just in time for people to see the total lunar eclipse. It says the "maximum will occur at 7.33pm BST from the UK, with the eclipse's actual maximum at 7.11pm when the Moon is below the horizon." The Moon will then gradually move out of Earth's shadow until 9.55pm. The advice is to find a high point with a clear view to the east, as the Moon will be low on the horizon and quite difficult to see.
