Hi everyone...Stuart here...with the Show Notes for Episode 15:
First ever detection of the binary partner involved in type 1a supernova explosion.
Astronomers have for the first time ever detected a binary companion to a star which exploded as a thermonuclear or type 1a supernova. The discovery provides a deeper understanding of these spectacular stellar blasts which are used as cosmic distance markers and provided the conclusive evidence of the accelerated expansion of the universe due to some unknown force which astronomers have named dark energy.
Glittering globular clusters reveal their stellar secrets.
Scientists have discovered that massive stellar groups known as globular star clusters can produce additional generations of stars by drawing-in fresh supplies of star forming molecular gas and dust from their surrounding galaxy. The findings mean globular star clusters are far more complex than astronomers previously thought.
How solar storms trigger Jupiter's auroral lights.
A new study has revealed that solar storms trigger Jupiter's intense northern and southern auroral lights by generating a new X-ray aurora eight times brighter than normal and hundreds of times more energetic than Earth's aurorae. The findings represent the first time Jupiter's X-ray aurora has been studied as a giant storm from the Sun hit the planet.
Cygnus Cargo ship launched to space station.
An Atlas 5 rocket has successfully blasted off from Cape Canaveral Air Force Station in Florida, carrying a Cygnus cargo ship loaded with supplies and experiments to the International Space Station. The Cygnus -- which is loaded with almost 3.4 tonnes of equipment -- will be captured by the space station’s robotic arm and maneuvered into a docking port tomorrow.
