How do tornadoes form on the Sun?  Why does Jupiter enhance our Meteor showers? And how can pulsars be used as a deep space positioning system? This month’s Naked Astronomy comes from the Royal Astronomical Society’s National Astronomy Meeting, held this year at the University of Manchester.  We’ll hear how Juno hopes to probe beneath the surface of Jupiter, find out how a cloud of carbon gives us clues about star formation in the early universe, and explore how astronomers have helped archaeologists to understand a standing stone over 4000 years old...

    01:15 - Juno's Trip to Jupiter

    Juno is NASA’s mission to Jupiter, launched in August 2011, and only last month successfully made fine adjustments to put it on course to reach the planet in July 2016. But in a time when astronomers are seeing further back than ever before, and spotting exoplanets and even who...

    10:10 - Jupiter's Influence on Meteor Showers

    Jupiter’s gravitational pull influences the rest of the solar system, even down to the meteor showers we see here on Earth. Aswin Sekhar at Armagh Observatory in Northern Ireland looked at how Jupiter’s enormous gravitational influence may alter the flight of Halley’s comet, an...

    16:37 - Pulsars as Deep Space GPS

    As we push further out into the universe, we’ll need to rely on spacecraft that can find their own way. But how do you navigate in open space? Professor Werner Becker, from the Max Planck Institute for Extra-terrestrial Physics in Munich thinks we may have to rely on pulsars…

    24:47 - Carbon in the Early Universe

    What happened in the early universe? Millimetre-wave radio telescopes have spotted a cloud of carbon from just 750 million years after the big bang, shedding some light on some of the big questions about early star and galaxy formation...

    32:33 - Seeing with SCUBA-II

    To help observe the universe, we need to see at a wide range of wavelengths. With SCUBA-II, researchers in the UK, the Netherlands and Canada have developed a state-of-the-art, wide-field camera that offers an unprecedented view of the universe at sub-milimetre wavelengths...

    39:32 - Standing Stones Aligned with the Sun

    Researchers at Nottingham Trent University have gathered new evidence that suggests that a 4000 year old, 2.2 metre tall standing stone at Gordom's Edge in the Peak District National Park was intentionally aligned to make use of the Sun...

    46:56 - Tornadoes on the Sun

    While looking at data from the Solar Dynamics Observatory, researchers at the University of Wales, Aberystwyth spotted something unusual – an enormous solar tornado. These are often associated with solar storms, and can help us understand complex magnetic structures on the Sun,...

    52:06 - The MAGIC of CINEMA Probes Space Weather

    Space weather is a hot topic in astronomy at the moment. One new mission, called CINEMA, hopes to add to our understanding of space weather using three tiny cubesats and innovative sensor technology...
