A new era of Moon exploration

As the United Nations marks International Moon Day on July 20 to commemorate the historic Apollo 11 landing in 1969, the global spotlight is shifting toward a new era of sustainable, peaceful lunar exploration. This annual observance highlights how much momentum deep-space exploration has gained following NASA's successful Artemis II mission. That historic flight, which took a four-person crew on a loop around the Moon and safely back, marked the first time humans have ventured beyond low Earth orbit in more than fifty years.

Moon exploration brought the first human footprints to another place in the universe.

Science’s great divide

The world’s scientists are mobilizing against climate disruption, inequality and emerging technologies—but the benefits are far from evenly shared. UNESCO data spanning 397 initiatives in 79 countries reveals that Africa hosts fewer than 10% of projects despite representing 17.5% of the global population. Funding has surged, yet weak coordination, limited infrastructure and gaps between researchers and policymakers still block progress. With open-science commitments often lacking action plans or oversight, the next breakthrough may depend less on discovering new knowledge than on ensuring every nation can access, shape and use it.

Seeing around the bend: Who gets to shape AI’s future?

Artificial intelligence is spreading at breathtaking speed, but access alone won’t determine who benefits. The real divide lies in who has the power to shape how AI is built, governed and used. As many countries race to adopt the technology, gaps in infrastructure, data, skills and local languages threaten to leave billions on the sidelines. Yet the future is far from fixed. Around the world, governments are laying the foundations for AI that serves people—not just markets. The choices made today will decide whether AI deepens inequality or becomes a force for more inclusive, human-centered development.

Steep hills, strong harvests: Rwanda’s tea crop

As the morning mist lifts over Rwanda’s rolling hills, thousands of tea pickers begin work on one of the country’s most valuable crops. Behind every carefully plucked leaf is a story of resilience, smallholder farmers and a national effort to produce premium-quality tea while protecting livelihoods. With support for sustainable farming, stronger value chains and a renewed focus on quality, Rwanda is turning its dramatic landscape into an economic advantage. From hillside plantations to teacups around the world, the country is brewing a future where agriculture creates opportunity, empowers rural communities and helps lift families out of poverty.

What we do

Due to the powers vested in its Charter and its unique international character, the United Nations can take action on the issues confronting humanity in the 21st century, including:

Maintain International Peace and Security

The United Nations came into being in 1945, following the devastation of the Second World War, with one central mission: the maintenance of international peace and security. The UN does this by working to prevent conflict; helping parties in conflict make peace; peacekeeping; and creating the conditions to allow peace to hold and flourish. These activities often overlap and should reinforce one another, to be effective. The UN Security Council has the primary responsibility for international peace and security. The General Assembly and the Secretary-General play major, important, and complementary roles, along with other UN offices and bodies.

Protect Human Rights

The term “human rights” was mentioned seven times in the UN's founding Charter, making the promotion and protection of human rights a key purpose and guiding principle of the Organization.  In 1948, the Universal Declaration of Human Rights brought human rights into the realm of international law.  Since then, the Organization has diligently protected human rights through legal instruments and on-the-ground activities.

Deliver Humanitarian Aid

One of the purposes of the United Nations, as stated in its Charter, is "to achieve international co-operation in solving international problems of an economic, social, cultural, or humanitarian character."  The UN first did this in the aftermath of the Second World War on the devastated continent of Europe, which it helped to rebuild.  The Organization is now relied upon by the international community to coordinate humanitarian relief operations due to natural and man-made disasters in areas beyond the relief capacity of national authorities alone.

Promote Sustainable Development

From the start in 1945, one of the main priorities of the United Nations was to “achieve international co-operation in solving international problems of an economic, social, cultural, or humanitarian character and in promoting and encouraging respect for human rights and for fundamental freedoms for all without distinction as to race, sex, language, or religion.”  Improving people’s well-being continues to be one of the main focuses of the UN. The global understanding of development has changed over the years, and countries now have agreed that sustainable development offers the best path forward for improving the lives of people everywhere.

Uphold International Law

The UN Charter, in its Preamble, set an objective: "to establish conditions under which justice and respect for the obligations arising from treaties and other sources of international law can be maintained."  Ever since, the development of, and respect for international law has been a key part of the work of the Organization.  This work is carried out in many ways - by courts, tribunals, multilateral treaties - and by the Security Council, which can approve peacekeeping missions, impose sanctions, or authorize the use of force when there is a threat to international peace and security, if it deems this necessary.  These powers are given to it by the UN Charter, which is considered an international treaty.  As such, it is an instrument of international law, and UN Member States are bound by it.  The UN Charter codifies the major principles of international relations, from sovereign equality of States to the prohibition of the use of force in international relations.

Structure of the
United Nations

The main parts of the UN structure are the General Assembly, the
Security Council, the Economic and Social Council, the Trusteeship Council, the International Court of Justice, and the UN Secretariat. All were established in 1945 when the UN was founded.

General Assembly

The General Assembly is the main deliberative, policymaking and representative organ of the UN. All 193 Member States of the UN are represented in the General Assembly, making it the only UN body with universal representation.

Security Council

The Security Council has primary responsibility, under the UN Charter, for the maintenance of international peace and security. It has 15 Members (5 permanent and 10 non-permanent members). Each Member has one vote. Under the Charter, all Member States are obligated to comply with Council decisions.

Economic and Social Council

The Economic and Social Council is the principal body for coordination, policy review, policy dialogue and recommendations on economic, social and environmental issues, as well as implementation of internationally agreed development goals.

Trusteeship Council

The Trusteeship Council was established in 1945 by the UN Charter, under Chapter XIII, to provide international supervision for 11 Trust Territories that had been placed under the administration of seven Member States, and ensure that adequate steps were taken to prepare the Territories for self-government and independence.

International Court of Justice

The International Court of Justice is the principal judicial organ of the United Nations. Its seat is at the Peace Palace in the Hague (Netherlands). It is the only one of the six principal organs of the United Nations not located in New York (United States of America).

Secretariat

The Secretariat comprises the Secretary-General and tens of thousands of international UN staff members who carry out the day-to-day work of the UN as mandated by the General Assembly and the Organization's other principal organs.

They lost their homes overnight. Now they're rebuilding together.

When powerful earthquakes struck parts of Venezuela in June 2026, thousands of families were forced from their homes in seconds. For Gusmaira, the disaster came just after giving birth. With her newborn still in hospital and communications disrupted, she spent hours not knowing whether her baby was safe. Like many families affected by the earthquakes, Yuleima and Gusmaira are now rebuilding their lives one day at a time. Despite the uncertainty, they are finding strength in their families and communities as they move forward. UNHCR, the UN Refugee Agency, and partners are supporting the government-led response, helping families access protection services, psychosocial support, documentation, medical care and other emergency assistance as they recover from the disaster. Across Venezuela, communities are beginning the long process of rebuilding. UNHCR continues to work alongside affected families, helping them move beyond survival and take the first steps towards restoring stability, dignity and hope. Learn more, and support families affected by the earthquakes in Venezuela.

Launching a new life from a refugee camp (AAN: S13-E5)

"Refugees do bring so much to the community, they bring a whole different culture, a whole different lens on life, and that is powerful and important."

War is Mary Maker’s earliest memory. Born in South Sudan and named Nyiriak — meaning "war" — she spent her youth living and working in one of the world’s largest refugee camps. Now a Goodwill Ambassador for UNHCR, the UN Refugee Agency, she is raising her voice on behalf of those she left behind, helping refugee students land scholarships to top universities.

“I want to be seen. I want to be heard. I want to be acknowledged. I want to be at the table, making decisions and feeling like a part of something. Are you able to see us? Are you? Are you able to go beyond the news and really understand that this is someone like you?”

After her family fled to safety, Mary built a new life of opportunity through education and hard work – finding her feet, and her voice, on stage. In this episode, she shares how she overcame a childhood marred by death and conflict, and how theater became both her refuge and her path forward.

The climate crisis is becoming a childhood crisis

UNICEF’s Children’s Climate Risk Report 2026 reveals a stark reality: 1.1 billion children now face at least three overlapping climate hazards, putting their health, education and futures at risk. While the climate crisis is a global phenomenon, its effects aren’t felt equally. Without identifying who the most vulnerable children are, where they live and how they are affected by climate-related impacts, it’s nearly impossible to develop practical and effective solutions. UNICEF’s report reveals how children’s exposure to the climate hazards, inherent physical vulnerabilities, and the gaps in the social services they rely on, undermines their rights and increases their risk of harm. The report calls for urgent action to put children at the heart of climate solutions.

Food on the frontlines of the Ebola Response

WFP has been providing food and other humanitarian assistance to Ebola-affected areas: hot meals to patients, family members and health workers; along with take-home food rations and nutrition support to other vulnerable people that together reach more than 1.2 million Congolese. Why? Because Food assistance helps patients and family members remain under observation, reduces the need for people to travel in search of food, and supports wider efforts to contain the spread of Ebola. In addition, WFP is providing logistics, telecommunications and air transport to move humanitarian workers and essential cargo to the frontlines of the Ebola crisis in eastern DRC.  WFP warns that conflict, displacement and rising food prices are worsening the crisis and is seeking US$72 million to sustain the Ebola response.
