Moons orbit planets, planets orbit stars, stars orbit within galaxies. It’s orbits all the way down. But occasionally objects can receive a powerful kick that sends them on a journey, never to return.
Today Awesome Astronomy will taking a look at the colour of stars and why stars appear the colours they do. Also how the mass of a star is related to its temperature, what happens to expanding dying stars and why we don’t see any green or purple stars.
We’ve always assumed that we lived in a perfectly normal star system with a normal star and normal planets. It’s all… normal. But with our modern understanding of billions of stars, just how normal is our Sun, anyway?
Today’s podcast we have a folklore from Mongolia about the birth of the brightest morning star and the evening sparkle stars.
What to observe in February? Listen to @awesomeastropod #skyguide and news round up today at #365DaysOfAstro. The team will cover Venus sample return mission, big far away star with very big planet, another ocean moon in Saturn and many more.
Today, @ActualAstronomy talk about the patterns in the sky both large and small as we share the guideposts to learning the night sky as well as some smaller asterisms you can see through binoculars and telescopes
Just like Brothers Grimm’s kissing the frog fairy tale, this software by Frank Shelly also helps us to find Earth approaching asteroids. More of it & AAVSO monitoring program at #365DaysOfAstro
Today Travelers in the Night will discuss about a 5 football field diameter asteroid which is near to the Sun as Venus. And establishment of standard stars to calibrate the measurement of the brightness of objects in space.
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.
