Exploring the first crewed Artemis mission, the future of lunar exploration and how spaceflight could help inspire greener technologies on Earth 

Newly released audio interviews reveal a personal, reflective side of Robert Oppenheimer 

Author Andy Weir and astrophysicist Becky Smethurst unpack the physics in the new Hollywood space epic 

<p>Humans are responsible for emitting over 40 billion tonnes of carbon dioxide into the atmosphere every year – and we all know that we need to reduce that figure to prevent devastating climate change. Listener Saugat wonders whether smart technology and artificial intelligence ... Show More

Even with the best efforts, it will be decades before we see any change in global temperatures through our mitigation efforts. Given the pace of global heating and the time lag before our emissions reductions have any impact, scientists are exploring additional ways of reducing g ... Show More

The latest IPCC assessment raised alarm about the rate at which manmade emissions are contributing to climate change. Much of the focus for action is on reducing levels of carbon dioxide, however there is a more potent greenhouse gas, methane, produced by natural and industrial p ... Show More

The political message from the COP meeting was a fudge over coal, but what does the science say? Surprisingly India seems to be on track to switch away from coal to renewables. We explore the apparent contradiction with Lauri Myllyvirta of the thinktank Centre for Research on Ene ... Show More

“AI can be a transformational tool in our fight against climate change," says Sims Witherspoon, a leader at the AI research lab Google DeepMind. Using wind power as her case study, she explains how powerful neural networks can help us better predict Earth's changing ecosystems an ... Show More

<p>If you are planning a trip, but you want to check the climate impact before choosing how to get there, then beware. Google has been seriously underestimating the carbon footprint of plane flights, and overestimating that of some train journeys. And its calculations don’t just ... Show More

Machine learning and particle physics go together like peanut butter and jelly--but this is a relatively new development. For many decades, physicists looked through their fairly large datasets using the laws of physics to guide their exploration; that tradition continues today, ... Show More
