Here are our picks for tonight's viewing on the box.
Horizon - 9pm, BBC2
Scientists predict this year will see a fit of violent activity on the Sun, propelling billions of tonnes of superheated gas and pulses of energy towards Earth. Sounds scary. This documentary helps to put things into context by talking to the weathermen as they try to predict what's coming and the footage of the Sun's churning plasma is quite something.
Big Fat Gypsy Weddings - 9pm, Channel 4
There's something of a Romeo and Juliet feel to this week's Gypsy Weddings as the controversial show meets travellers who have found romance outside their own community. Cage Fighter Tony's family aren't happy he's having a baby with a glamour model, plus a couple from the first series pop back onto the scene.
