Two long-lost episodes of Doctor Who from the William Hartnell era, which had not been seen since 1965, have been released after being discovered in a private film collection. The episodes, 'The Nightmare Begins' and 'Devil’s Planet', are parts one and three of a mostly lost 12-part adventure called The Daleks’ Master Plan, written by Terry Nation, the creator of the Daleks, and broadcast as part of the third series of Doctor Who in November 1965.The episodes feature Peter Purves as the Doctor’s companion, Stephen. They were recovered by Film is Fabulous, a charitable trust dedicated to securing and preserving private film collections. The original 16mm telerecordings of the two Dalek episodes have been restored and made available on iPlayer in the UK.This discovery marks a significant milestone for fans, as it includes the first appearance of Nicholas Courtney in the show, playing Bret Vyon. Courtney later became a regular character, playing Alistair Gordon Lethbridge-Stewart, known as the Brigadier of Unit. 95 episodes of Doctor Who from the 1960s remain missing from the archives, having been wiped or junked by the BBC during the 1970s.

The increasing congestion of Earth's orbit with satellites is raising concerns about the environmental impact of space activities. A recent UN report highlighted the urgent need for sustainable practices to manage potential orbital congestion and environmental impacts.One of the most pressing issues is the risk of space debris, also known as 'space junk', which includes discarded rocket stages and defunct satellites. The surge in orbital activity has created a significant collision risk, and there have already been a handful of crashes. In 2007, a Chinese anti-satellite weapon test intentionally blew up a weather satellite, creating a dangerous cloud of space debris.Researchers fear that the impact of space activities on the ozone layer, which shields the planet from radiation, could be significant. A study found that roughly 10% of particles in the stratosphere contain metals that originated from space activities such as rocket launches.The Guardian has launched an interactive project to visualize the tens of thousands of human-made objects spinning around the globe. The project reveals a significant problem which, if left unchecked, could disrupt some of humanity's most important services such as the internet and weather prediction.As a global society, we rely on satellites constantly, not only to help us navigate around using Google Maps, but also to provide internet access and, critically, predict the weather. Space-based monitoring of the Earth also allows researchers to track deforestation, desertification, glacier and ice-cap melt, and the spread of oil spills.

SpaceX has submitted paperwork for an initial public offering that could debut as early as June or July, targeting a capital raise of $75 billion. If the market pricing aligns with analysts’ forecasts, the launch could lift the company’s valuation to nearly $1.5 trillion, roughly double its worth in December. Such a valuation would place founder Elon Musk on a clear trajectory toward becoming the planet’s first trillionaire, a milestone that would eclipse the $25.6 billion record set by Saudi Aramco’s 2019 IPO. Renaissance Capital’s data analyst Angelo Bochanis told Reuters that, much like Tesla, SpaceX’s market price will hinge on investor confidence in Musk’s long‑term vision. "Investors are clamouring for any exposure to SpaceX," he added. Despite Musk’s controversial public persona and his involvement in multiple high‑profile ventures, industry experts remain bullish. Kat Liu, vice‑president at IPOX, noted that SpaceX is "operationally mature, technologically ahead in several key areas, and profitable," providing a solid foundation for a public listing. The company’s recent merger with Musk’s artificial‑intelligence startup xAI and the continued dominance of its Starlink satellite network—now the world’s largest satellite communications platform—have reinforced investor interest. SpaceX’s ambitious roadmap includes a lunar base and a crewed Mars mission, though timelines remain uncertain. Musk has previously admitted a "50‑50 chance" of delivering an uncrewed Starship to Mars by the end of 2026. Financial data firm Pitchbook estimates the IPO could nearly double the company’s market cap, underscoring the scale of potential investor demand. If realized, the offering would not only reshape the space‑tech sector but also set a new benchmark for public market fundraising.

The Artemis moon mission is a landmark international project that embodies the spirit of unity and cooperation. Over 50 years ago, the Apollo astronauts' photographs of Earth from the moon had a profound impact on society, highlighting our planet's fragility and finiteness.This new mission, involving 11 nations and 61 countries that have signed the Artemis accords, aims to revive that sense of unity and shared purpose. The crew of Artemis II, comprising calm, curious, kind, and thoughtful individuals, will fly around the moon and take photographs of Earth from a distance, potentially streaming the experience live.The mission's commander, Reid Wiseman, emphasizes that "we are going as humanity," while astronaut Christina Koch notes that "any country that's interested in exploring, come, come along, be a part of this." Victor Glover, set to be the first African American to fly to the moon, adds that space exploration teaches us that "we're all brothers and sisters."As the Artemis astronauts prepare to experience the profound view of Earth from the moon, they are accompanied by a tiny silicon disc of goodwill messages from world leaders, placed on the lunar surface by the Apollo 11 crew. This message, from Eric Williams, then prime minister of Trinidad and Tobago, reads: "It is our earnest hope of mankind that while we gain the moon, we shall not lose the world."The Artemis mission has the potential to inspire a new generation and promote global cooperation, serving as a reminder that we are "riders on the Earth together."

David Attenborough’s voice returns to British screens in ‘Secret Garden’, a BBC One series launched to celebrate the network’s 100th birthday. Unlike his classic wildlife documentaries, the show turns the lens toward the UK’s own backyards, exploring how gardens can rival tropical rainforests in biodiversity.Series producer Bill Markham explains that the programme deliberately avoids the usual “lions and tigers” spectacle, aiming instead for a relatable, garden‑centred narrative. He notes that British gardens collectively cover more area than all national nature reserves combined, and that an average garden can host up to 2,600 different species.The series tackles the contentious issue of domestic cats. With 9.5 million pet cats in Britain, Attenborough reveals they may kill around 55 million birds each year. Simple measures—such as fitting cats with bells—can slash hunting success by one‑third, while raising bird feeders reduces fatalities further.Markham stresses that the current predator‑prey balance is “unfair on the prey”, noting that cats are “the biggest predator in our gardens” yet are constantly fed, leading to an unsustainable population. He cites ecologist Dr Davide Dominoni, who suggests that keeping cats indoors during the breeding months of April and May could dramatically lower bird deaths.Beyond cats, the series examines other garden‑linked wildlife challenges. Each year, over 30 million pheasants—an Asian species—are released into the countryside, where they prey on native insects, reptiles, and amphibians. Markham argues that despite the countryside lobby’s claim that pheasant shooting sustains rural jobs, the practice “mess‑es with the ecology”.‘Secret Garden’ also showcases rare footage, including a pine marten hunting sand martins, an otter preying on ducks, and intricate mayfly battles reminiscent of the famed “snakes vs. iguana” scene from Planet Earth II. These moments underline the hidden drama unfolding in everyday green spaces.Markham hopes the series will soothe the growing eco‑anxiety many feel about climate change. He points out that the UK boasts roughly 25 million gardens, with 80 % of the population having access. Simple actions—like planting a native tree to boost caterpillar supplies for birds—can make a measurable difference.While the show may provoke cat owners and countryside advocates, Markham believes the nation’s love for “animals, gardens and David Attenborough” will drive a collective re‑thinking of garden stewardship. As Attenborough reflects, his first encounter with nature likely occurred in his own garden, setting him on the path to becoming the world’s most renowned naturalist.‘Secret Garden’ airs from 5 April on BBC One and iPlayer.

The recent open letter from 60 clergy members, addressed to the author, underscores a shared concern for planetary stewardship and acknowledges that human‑generated carbon emissions are warming the climate. However, the signatories and the author diverge sharply on the appropriate policy response. Marshall contends that an outright ban on fossil fuels is both impractical and ideologically driven, creating a collective‑action dilemma for the UK. He notes that while the nation pursues a rapid net‑zero transition, major emitters such as India and China operate on markedly different timelines, and the United States has withdrawn from the Intergovernmental Panel on Climate Change (IPCC). This leaves Britain navigating a path of unilateral economic disarmament. Industrial electricity rates in the UK have surged to two‑and‑a‑half to three times those in China and four times those in the United States. Such cost differentials are eroding the global competitiveness of sectors ranging from steel and oil refining to chemicals, automotive manufacturing, and emerging AI industries. The result, according to Marshall, is a wave of factory closures, investment pull‑backs, and significant job losses across the nation's industrial heartlands. Beyond macro‑economic concerns, the policy’s social toll is stark. Older and low‑income households are bearing the brunt of soaring energy bills, with an estimated 2,500 excess deaths last year attributed to an inability to adequately heat homes. This humanitarian impact, Marshall argues, contradicts the very notion of “human flourishing” that climate advocates champion. While acknowledging that every policy entails trade‑offs, Marshall warns that the clergy’s proposal would impose severe personal costs on working‑class Britons without delivering the promised climate benefits. He concludes that the current net‑zero trajectory is unlikely to curb global warming and instead jeopardizes the UK's economic vitality and social wellbeing.

Aarti Holla-Maini, a British lawyer with a background in the satellite business, is the director of the UN's Office for Outer Space Affairs (Unoosa). She is responsible for alerting the UN secretary general if a large asteroid is on a possible collision course with Earth.On 27 December 2024, a robotic telescope in Chile spotted a distant rock, asteroid 2024 YR4, which was initially estimated to be the size of a small building. As the asteroid's impact probability increased, Holla-Maini's team drafted a letter to the UN secretary general, triggering the first global notification since the UN established a planetary defence collaboration in 2013.The asteroid's size and speed meant an impact could release energy comparable to hundreds of times the power of the Hiroshima bomb, potentially wiping out a city or region. The asteroid reached level three on the Torino Impact Hazard Scale, indicating a threat to human civilization.Holla-Maini's team worked with the International Asteroid Warning Network and other experts to track the asteroid. Although its impact probability peaked at more than 3% in February 2025, it has since dropped to a negligible level. The asteroid scare served as a useful test for Unoosa's role in planetary defence.Unoosa plays a critical role in registering satellites launched into Earth's orbit and acts as an informal 'hotline' for potential satellite collisions. Holla-Maini's small team of 35 employees punches well above its weight, managing a massive remit as governments and businesses increasingly operate in space.

The music of Bluey, the beloved Australian TV show, has captured the hearts of both children and adults worldwide. With over 4.8 billion minutes watched in Australia alone and 126 million streams of its theme song, the show's soundtrack has proven to be a crucial element in its success. Composer Joff Bush shares the secret to creating music that 'hits you in the feels.' According to Bush, it's all about seeding elements of music throughout an episode to create a powerful emotional payoff. For example, in the episode 'Sleepytime,' Bush used Gustav Holst's Jupiter from The Planets to convey the idea that a child's parents will always be there to love and support them. The new album, Up Here, features a chamber orchestra and marks a significant milestone in the show's music journey. Bush notes that the use of a chamber orchestra was initially met with skepticism but has ultimately resulted in something truly special. 'It's really ambitious, but having that many adults dedicate their craft to make this music as beautiful as it can be, for children? It was just wonderful.' The music of Bluey is not just emotionally devastating; it's also incredibly joyful. Children who spoke to the Guardian described the opening song as 'making them happy' and perfect for games like musical statues. For adults, the music often evokes strong emotions, with many confessing to watching the show after their kids have gone to bed. Bush's approach to scoring Bluey is rooted in his understanding of the show's themes and his own experiences as a father. 'Watching it now, I get it – why a certain episode hits you in the feels more.' His daughter even got to conduct the orchestra during a recording session, leaving her 'enamoured' by the experience.

Sir Paul Marshall, the co-owner of GB News and a self-described 'committed' Christian, has been criticized by a group of 100 church leaders over the TV channel's attacks on climate science and action. The leaders, including former Archbishop of Canterbury Rowan Williams, argue that Marshall's statements on climate change are misleading and that his hedge fund's £1.8bn investments in fossil fuels present a conflict of interest.Marshall has stated that the UK has been infected by 'climate derangement syndrome' and that efforts to cut planet-heating emissions are 'impoverishing people.' In response, the church leaders emphasized that 100% of global heating since 1950 has been caused by human emissions and activities, according to the world's climate scientists. They also noted that decarbonization is a huge growth opportunity that will save trillions of dollars in the long term.The leaders, in an open letter, urged Marshall to be transparent about any personal conflicts of interest and to declare his financial interests in fossil fuels. They cited research that found GB News broadcast 953 attacks on climate science and climate action in the period immediately before and after the 2024 general election.Marshall responded that 'the Gospel entreats us to look after the vulnerable' but argued that pursuing an 'ideological' net zero policy was 'a path of unilateral economic disarmament and self-harm.' He also stated that he was not involved in the editorial decisions of GB News, which has lost £131m since its launch in 2021.The Christian leaders' criticism of Marshall and GB News highlights the ongoing debate over climate change and the role of media outlets in shaping public discourse on the issue. As more than 100 countries have net zero policies and the UK's net zero economy grew by 10% in 2024, the pressure on media outlets to provide accurate and responsible reporting on climate issues continues to grow.
