Starwatch: Prepare for a pre-dawn Venus at its peak
This week, the planet is located in the constellation of Gemini, the Twins. It will be unmistakably bright, shining with an apparent magnitude of –4, making it brighter than everything else in the sky, except the Sun and the moon. This will mean it is visible even from the most light-polluted urban environments.
If you have a small telescope to hand, the crescent phase of Venus will be clearly visible – but stop observing before sunrise, as even a glimpse of the Sun through a telescope can cause permanent eye damage.
Observers in the southern hemisphere can also enjoy Venus in the early morning, but it will appear lower on the eastern horizon. Thankfully, its dazzling brightness should still make it obvious.
The chart is a heads up for next week. On 12 August, Venus and Jupiter will meet in the pre-dawn skies. The chart shows the view looking east from London at 5am BST.

Hot, dry summers bring new 'firewave' risk to UK cities
Cities across the UK are facing a growing threat from an emerging phenomenon called "firewaves" as temperatures rise due to climate change, scientists have term, coined by researchers at Imperial College London, describes multiple urban wildfires triggered by extended periods of hot, dry warning comes as firefighters battled three separate heath fires in London and a dramatic gorse blaze on Arthur's Seat in Edinburgh in recent days, as this summer's latest heatwave left vegetation across both capitals dangerously fires, though now contained, highlight the increasing vulnerability of urban areas to wildfires - a risk that was once considered largely rural. Guillermo Rein, professor of fire science at Imperial College London, has been working alongside the London Fire Brigade to help predict when conditions are ripe for a "firewave".Based on current forecasts, he believes London could be at risk again by this Fire Brigade Assistant Commissioner Tom Goodall said he welcomes any research that helps predict the likelihood of wildfires service is "ready to tackle the threat of wildfires head-on to help protect London's communities and green spaces", he added. Prof Rein's research finds that, after ten consecutive days of very dry weather, vegetation becomes so desiccated across wide areas that the likelihood of multiple fires igniting simultaneously rises detailed incident data from the London Fire Brigade dating back to 2009, combined with weather records, the team identified key factors that drive wildfire outbreaks in of the most important is a measure of how much moisture the atmosphere can extract from the land, known as the "vapour pressure deficit".The higher the deficit, the drier the vegetation becomes, and the more easily it ignites."Vegetation doesn't just become a bit more flammable," explained Professor Rein, "it becomes much more flammable.""Once the moisture content of the vegetation drops below a certain threshold, even a small spark can lead to a fast-spreading fire," he added. Most fires are started by humans, whether accidentally or deliberately. But a warming world is creating conditions more conducive to these blazes."Climate change is bringing more heatwaves and longer dry spells," Prof Rein said."These conditions dry out fuels and increase the risk of wildfires. That risk is much greater now than it was even a decade ago."While the researchers focused on London, concerns are widespread."I worry about all other UK cities and other northern European cities in particular because climate change seems to be making green vegetation that was not flammable very flammable indeed," said Prof Rein."And these places don't have a history of dealing with wildfires so don't have as much institutional experience as cities in the south of the continent." Managing fire risk Urban environments like London, with their abundance of parks and green spaces bordering residential zones, are particularly concept of a "firewave" is meant to capture the unique danger posed when several fires erupt at once in densely populated areas, which has the potential to overwhelm emergency services and threaten homes and happened in the summer of 2022 when UK temperatures exceeded 40C for the first time on 19 July 2022, London Fire Brigade (LFB) experienced its busiest day since World War broke out simultaneously across the city, including a devastating blaze in Wennington, East London, which destroyed 37 buildings, five cars, and forced the evacuation of 88 Betts, a borough commander with the LFB, has extensive experience dealing with wildfires in urban emphasises the serious threat they pose, especially when open spaces are adjacent to residential properties."The potential for fires to spread into homes is very real," said Cdr Betts."We're seeing more extreme weather events, and that's why the London Fire Brigade has adopted a much more proactive approach." To meet this growing challenge, the LFB says it has invested in new technologies and now play a critical role in wildfire response, providing real-time aerial views that help commanders map fire spread and direct resources where they are needed most."The bird's-eye view from drones gives us a huge boost in situational awareness," explained a spokesperson from the LFB."It allows us to target our efforts where the risk to life and property is greatest."In addition to drones, the brigade has introduced off-road vehicles capable of reaching fires in difficult terrain, such as heathland and vehicles can be used to create firebreaks – using water to soak the ground to help stop fires from spreading Imperial College London researchers argue that the Met Office's current definition of a heatwave does not adequately reflect the wildfire risk in urban propose it adopts the term "firewave" to signal periods of extreme fire danger in cities - a concept they hope will inform future public safety strategies and climate resilience Met Office has been asked for comment.

Baby lizard hatched at British zoo after extremely rare ‘virgin birth'
A BABY lizard was hatched at a British zoo following an extremely rare 'virgin birth'. Izzy the eastern casquehead iguana was conceived with no male involvement. She hatched from one of two marble-sized eggs laid by five-year-old female Alma, which went through parthenogenesis — a form of reproduction when an embryo develops from an unfertilised egg. The process, which happens in fewer than one in 1,000 vertebrate births, sees the body find a way of filling in for genes usually provided by sperm. Izzy, whose species is native to Central and South America, was born on Sunday at Battersea Park Children's Zoo in South West London. Manager Jamie Baker, 30, said: 'We were amazed. "We've no male eastern casquehead iguanas so when we discovered one of our females had laid eggs, it was exciting. 'We didn't think they'd hatch but decided to incubate them anyway as we were aware that the species have been known to reproduce via parthenogenesis.' He said Izzy, a genetic clone of her mum, was about the size of an adult little finger. He said: 'She's growing well. "She's in her nursery enclosure feeding on fruit flies and tiny crickets. 'We're keeping her on her own because if we left her in with the adults they'd eat her. Moment iguana casually crawls onto tennis court before worker is forced to shoo it away "They're not an animal that gives parental care. 'Our priority is to get Izzy to a good enough size so that she can move in with the adults.' 1

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.
