Naked Astronomy, from the Naked Scientists

How are sunspots born? What does a black hole collision look like? How long does it take to make a full-size galaxy? This month on Naked Astronomy, we find out why people searching for pulsars might spot colliding black holes in their data, how galaxies may form quicker than predicted, and where in the sun sunspots first arise. Plus, news from gravity probe B, why there's no more space on the moon for craters, and how as many as half of all hot Jupiters may be spinning the wrong way. Like this podcast?

In this special podcast from the National Astronomy Meeting in Llandudno, we hear how twisted sunspots cause solar flares, how 17th century poetry can put a date on a supernova, and why some pulsars are part-timers. We'll find out how CANDELS and LOFAR can probe the early universe, while DEBRIS looks for dusty disks around stars. Plus, we shed light on your solar science questions! Like this podcast?

In this special edition of the Naked Astronomy podcast we look at the astronomical events held at the Cambridge Science Festival. We'll hear from Dr Dan Stark about exploring the early Universe, find out what tooth x-rays and telescopes have to do with the man who coined the term "Big Bang" and ask if our Universe is but one of many... Plus, we catch up with Carolin Crawford, Andrew Pontzen and Dominic Ford to find out what they've been doing this month to bring space science to the wider public. Like this podcast?

In this month's Naked Astronomy, we explore the unique system of six planets orbiting the star Kepler 11, and find out what to expect from the James Webb Space Telescope. Plus news of the runaway star spotted by WISE - the Wide-field Infrared Survey Explorer, a STEREO view of the whole Sun and how a galaxy spotted at a redshift of 10 can teach us about star formation in the early universe.

This month on Naked Astronomy, we discover the streams of antimatter coming from lightning on Earth, and find out how to study the stars that ended the dark ages and brought light to the universe. We hear about Jupiter's role in Earth asteroid impacts, Cassini's flypast of Saturn's moon Rhea and the first science results from the Planck mission. Plus, your questions on light speed route planning, outrunning sunset and why the solstice doesn't coincide with the earliest dawn! Like this podcast?

This month, we read the history of Martian science in a collection of globes, and find out why it's important to understand ancient and aboriginal astronomy. We find out why some Gamma Ray Bursts (GRBs) are shrouded in darkness, discuss the recent controversy around arsenic-using bacteria and get the high-speed low-down on the Hubble Space Telescope. Plus, we tackle your questions on gravity, relativity and the edge of the universe. Like this podcast? Please help us by supporting the Naked Scientists

The International Space Station celebrated 10 years of habitation this month, pushing the boundaries of our knowledge of life in orbit. We find out more about living in space, as well as discover new gravitational lenses in this month's Naked Astronomy. Also, news of lead ion collisions in the LHC and giant gamma-ray bubbles emitting from our local black hole. Plus, your questions on gravity, neutron stars and dark matter. Like this podcast?

What would an extrasolar observer see of our solar system? We find out in this month's Naked Astronomy as well as explore the events that led to climate change on a cosmic scale. Plus, news of an asteroid flyby, surfing Venus' atmosphere and the end of the WMAP. We take on your space science questions, including the best place to site a space elevator! Like this podcast?

How do you make steam inside a star? We explore the science of solar chemistry to find out how water molecules are created inside the envelope of red giants and We get an delegates-eye-view of the European Planetary Science Congress in Rome. In the news we discover a new way to find asteroids, explain the dust clouds surrounding binary stars and find out how the fine structure constant seems to vary over both space and time. Plus, we take on your space science questions on diluted light, Horava Gravity and building black holes! Like this podcast? Please help us by supporting the Naked Scientists

Is our solar system normal? We compare ourselves to the ever increasing list of exoplanets to find out if we're the weird ones in the universe in this month's Naked Astronomy. Also, we explore the Nili Fossae region of Mars, where the rocks may contain evidence of early life - if only we could get there to find out. Plus, news about the shrinking moon and buckyballs in space and we tackle your space science questions. Like this podcast? Please help us by supporting the Naked Scientists
