How Doctors on Earth Stopped a Medical Emergency in Space

The video discusses two main topics: a medical emergency on the ISS where a blood clot was discovered in an astronaut's jugular vein and treated from Earth, and the discovery of some of the universe's first stars. The blood clot was found accidentally during an unrelated study, and NASA managed to treat it with limited resources. The incident highlights the challenges of medical care on long space missions. The second topic covers the discovery of early stars using telescopes, providing insights into the universe's formation and raising new questions about cosmic conditions.

What did scientists recently discover that might be some of the first stars in the universe?

How did astronomers estimate the age of the stars they discovered?

What are the implications of discovering stars that formed just after the Big Bang?
