Today we feature Cecilia Payne-Gaposhkin, woman astronomer & astrophysicist who proposed that stars were composed primarily of hydrogen and helium.
As part of her trip to England, Pamela had a chance to sit down with Oxford astrophysicist Chris Lintott and record an episode of Astronomy Cast. From the first stars to the newest planets, molecules and the chemistry that allows them to form affects all aspects of astronomy. While most astronomers group molecules into three bins of hydrogen, helium and everything else, there are a few who do proper chemistry by studying the sometimes complex molecules that form between the stars.
This week we’re going to talk about famous stars. We’re talking about those hot balls of plasma across the distant Universe. #365DyasOfAstro
Time rules our lives. We live each day with the moments broken up into hours, minutes and seconds. But can you imagine not being able to tell time at all, where the movements of the Sun and the stars was the only way to know when it was? Let’s learn about time.
Today @CheapAstro is full of stars. What do different pulsar frequencies mean? How are stars named? Find out the answer at #365DaysOfAstro
What’s the difference between a “dwarf” and “giant” star? How are stars born? What happens when stars die? I discuss these questions and more in today’s Ask a Spaceman!
The biggest black hole ever seen?
What’s the difference between planets and stars? Are particles inside of spacetime? Why can’t we communicate faster than light? @PaulMattSutter will discuss this topic at #365DaysOfAstro
Discussions about the violent outbursts, known as coronal mass ejections with Priscilla Muheki & Prof Hakeem Oluseyi. More in @cosmicsavannah at #365DaysOfAstro
