Join us on Saturday, August 1st, as Prof. Sarah Gallagher walks us through the final chapters of stellar lives, what these dramatic endings leave behind, and what […]

We've been littering in space for decades – and it's starting to come back down. As the number of satellites and rocket launches grows, so does the amount of debris orbiting Earth, and not all of it stays up there. Join us on Saturday, August 8th as Tammy Do explores the growing problem of space […]

Look up at the Moon on a clear night, and you'll see its surface is covered in craters. But who gets to name them – and how did that process evolve over centuries? Join us on Saturday, August 15th as Rina Rast takes us through the rich history of lunar crater naming, tracing how this […]
