In Chile, a powerful new telescope has just given a taster of what we can expect from it later this year, when it will be used to survey the cosmos over a ten-year period. In one image it revealed vast colourful gas and dust clouds swirling in a star-forming region 9,000 light years from the Earth. 

Housed in the Vera C Rubin Observatory, which sits on a mountain in the Chilean Andes, the telescope is designed to get giant images of the sky about one hundred times larger and quicker than any other existing telescope can achieve. It contains the world’s most largest digital camera, the size of a large car. 

When the Legacy Survey of Space and Time begins towards the end of 2025, the camera will film the entire Southern hemisphere night sky for the next decade, every three days, repeating the process over and over. And it will focus on four areas: mapping changes in the skies or transient objects, the formation of the Milky Way, mapping the Solar System and understanding dark matter or how the universe formed. 

So, on this week’s Inquiry, we’re asking, ‘What will Chile’s latest telescope tell us about the Universe?’

The Inquiry

When Chancellor Olaf Scholz fired his finance minister, Christian Lindner last month, Germany’s ‘traffic light’ government collapsed, an uneasy coalition between parties with differing perspectives and strained relations, the Social Democrats, the Greens and the Free Democrats.

At the heart of the political dispute lie deeply opposing views about spending plans, and how to fund much needed investment in infrastructure projects such as transport, education, green energy and digital technology, in order to boost Germany’s international competitiveness.

Falling demand both domestically and overseas for manufacturing goods, the pandemic, war in Ukraine and high energy costs have weakened Germany’s economy. So how can Germany reinvigorate its exports and economic growth? On this episode of The Inquiry, we’re asking: Does Germany need to reinvent itself?

Does Germany need to reinvent itself?

Accusations of sabotage have been made after a Chinese merchant ship cut through two important undersea cables in the Baltic Sea. Eight of the nine states in the Baltic are members of Nato but Russia has access to the sea from St Petersburg and for its Kaliningrad exclave. 

With previous incidents of damage to underwater pipelines and cables, there is concern that the security of critical underwater infrastructure is at risk from ‘grey zone’ activities - damaging but deniable incidents below the level of outright war. 

David Baker hears how countries’ security is threatened by incidents like these. The pipelines that were cut ran between Finland and Germany and Sweden and Lithuania. He asks who can intervene to protect these assets in the Baltic. Can Nato respond?

Our experts this week are: Elizabeth Braw, senior fellow at the Atlantic Council Scowcroft Centre for Strategy and Security, and the author of an upcoming book called The Undersea War; Helga Kalm, director of the Lennart Meri Conference in Tallinn, Estonia; Marion Messmer, senior research fellow in the International Security Programme at Chatham House; Tormod Heier, professor at the National Defence University College in Oslo, Norway and a former officer in the Norwegian Intelligence Service.

Can Nato protect the Baltic Sea?

The Himalayan Kingdom of Bhutan, sandwiched between China and India, is perhaps best known around the globe for its unconventional measure of national development: Gross National Happiness. The concept was introduced back in 1972 by the fourth King of Bhutan, Jigme Singye Wangchuck. It assesses the country’s overall wellbeing on the basis of sustainable and equitable socio-economic development; environmental conservation; preservation and promotion of culture; and good governance. 

But the Bhutanese are now finding that their cautious approach to balancing economic growth with the well-being of their citizens, is proving difficult to sustain in light of mounting economic problems. The country which has a population of less than 800,000, is experiencing high levels of youth unemployment and many young people and skilled workers are leaving for countries like Australia and Canada. 

To try and counter this brain drain and to attract new investment into the country to help the economy grow, Bhutan has plans to create a ‘Mindfulness City’. This multi-million dollar project is being spearheaded by the current monarch. At its core will be a scaled up, less cautious version of Bhutan’s key concept, which the Bhutanese Prime Minister has called Gross National Happiness 2.0. 

So on this week’s Inquiry we’re asking ‘Can Bhutan retain its happiness?’

Can Bhutan retain its happiness?

Robert F Kennedy Jr, nephew of America's 35th President, John F. Kennedy, has been nominated to be the next US health secretary by President-elect Donald Trump. The post oversees everything from medical research to food safety and public welfare programmes. 

Kennedy has been the face of “Make America Healthy Again”, a movement dedicated to “public health, sustainable practices and a government that truly serves the people”.

This week of The Inquiry, we look at how MAHA wants to tackle chronic disease, in particular obesity. Will RFK carry these ideas into public office? How will food corporations and colleagues in the US Congress react? How feasible is it for the US Health Secretary to shift the dial on healthy eating?

Can RFK Jnr ‘make America healthy again?’

Cancer is a disease that will affect 1 in 5 people in our lifetime, and it’s estimated that around 20 million people worldwide will be diagnosed with some form of cancer in 2025.

But how might a vaccine help in the treatment of cancer?

Numerous trials began testing the viability of cancer vaccines in 2024, including one for melanoma and another for lung cancer. 

With all the promise that these new cancer vaccine trials bring for cancer patients, we explore the different ways in which vaccines could work within the body, and how the time at which future vaccines are administered may vary according to the cancers they are targeting.

This week on the Inquiry we’re asking: Are we close to a cancer vaccine?

Drinks with toxic ingredients have been linked to deaths and poisonings in Turkey, Laos and India in 2024. 

Fake alcohol is unrecorded and unregulated alcohol that hasn’t been registered in official statistics for sales, production or trade. The range of unrecorded alcohol includes alcohol smuggled across borders, counterfeit alcohol and homemade brew. 

This week of The Inquiry we look at how toxic and widespread fake alcohol is. What are the health risks of drinking contaminated alcohol? Bootleg alcohol is big business for criminals, are governments doing enough to combat the illicit alcohol trade?

In December 2024, the decades-old Assad regime in Syria fell following 13 years of brutal civil war.

The Islamist rebel group, Hayat Tahrir al-Sham, seized power in the capital Damascus, having co-ordinated a lightning offensive along with other opposition forces across the country.

This week on The Inquiry, we examine how recent events led to the current situation, who the main players are vying for control, and the many challenges facing both the new government and the Syrian people.

China has approved the construction of what will become the world’s largest hydropower dam in Tibet. Located in the lower reaches of the Yarlung Tsangpo river, it could generate three times more energy than the Three Gorges Dam – also built by China - and currently the worlds’ biggest.
 
This Inquiry examines how important hydropower is for China’s economy, whether it will meet its climate goals and whether this new dam is a “safe project that prioritises ecological protection” as China claims. We look at how it’ll be built, and why some in neighbouring countries have concerns.

Why is China building the world’s biggest dam?

In the decade that followed the Great Financial Crisis, inflation rates remained low and steady, and in some cases even threatened to turn negative, as economies around the world struggled to recover.

This era came to an abrupt end in recent years following the double economic shocks of the Covid pandemic and Russia’s invasion of Ukraine. Many central banks and senior policymakers were caught on the back foot as inflation rates soared to levels not seen for nearly half a century in some countries.

Although rates have since come down from those highs, they are still proving tricky to completely get under control, causing concern among some observers. We explore what inflation is, where it comes from, what has been happening in recent years and what the outlook might be. Our panel includes

The Panama Canal, a crucial artery for global trade, is at the centre of growing tensions between the United States and China. Donald Trump has claimed that Chinese companies exert undue influence over the waterway, accusing Panama of overcharging US businesses. But does the US still have a legitimate stake in the canal?

With Trump demanding action, Panama faces a difficult choice. Could a renegotiation of tolls or a review of Chinese port contracts ease US concerns?

How can Panama satisfy President Trump?

It’s graduation day at the end of a religious summer school in Yemen’s Saada province. A class of young boys are off on a trip to a shrine. In a land of war, they are happy - jostling and full of energy on their school bus. 

Moments later, most of the boys are dead. A Saudi-led coalition airstrike has hit their bus. The bomb that was dropped by the Saudis was made in the United States, and Saudi Arabia is the America’s single biggest customer when it comes to buying arms.

Critics argue that Donald Trump is quietly escalating America’s role in the Saudi-led war on Yemen, and many, including US Congress, have begun to question the relationship between the United States and Saudi Arabia. Will the US support Saudi Arabia no matter what? So on this week’s Inquiry we’re asking, who’s in the driving seat when it comes to the US – Saudi alliance?
