Top Tips for Urban Stargazing

Blogging science to life

Tue 7 January 2014, Lee

You might think that there is too much light pollution in Bristol to go stargazing, but actually being a city dweller needn’t stop you. Bristol has three Dark Sky Discovery Sites recognised for their stargazing potential and all are within walking distance of At-Bristol! Read on to find out where they are and how best to make the most of them with our Top Five Stargazing Tips.

Where to go:

Durdham Downs, Clifton

The Downs aren’t just for five-a-side football and jogging. This large open space, high above Avon Gorge provides great, unobstructed views of the night sky.

Leigh Woods & Ashton Court, Long Ashton

Normally the location for festivals and picnics on long summer days, why not make the most of Bristol’s biggest park during the winter months? With the sun setting so early, it doesn’t even have to be a late night.

Victoria Park, Totterdown

The nearest Dark Sky Discovery Site to the City Centre and surrounded by nice pubs if the grown-ups need supplies! Climb to the top of this hilly green space so the trees don’t spoil your view and you’ll even find benches to sit on whilst you gaze.

A little further afield, Exmoor National Park is one of only three sites in the UK that has been internationally recognised as a Dark Sky Reserve.

Top Five Stargazing Tips

  • Check the weather: You won’t see anything on a wet, cloudy night so make sure you’re efforts are not thwarted by the Great British weather. Clear, dry and cold nights are perfect conditions to admire the stars.

  • Wrap up warm: You’ll be outside and standing still so wear a warm jacket, hat and gloves. You might even want to take a flask of tea and some snacks for a midnight feast…

  • Use binoculars: You don’t need expensive telescopes to get started with stargazing. The brightest stars you can see with your eyes. For more detail, zoom in with binoculars – easier to aim and focus than a telescope. Modern binoculars are more powerful than the telescope Galileo used to discover Jupiter’s moons!

  • Take a red torch: Your eyes will adapt to the dark when you’re out stargazing – your pupils dilate to let in as much light as possible. A sudden bright light like a torch will make your pupils contract and you’ll be back to square one. If you need to read any star charts or maps then paint the end of a torch with red nail varnish – this soft red light will allow you to read and stay dark-adapted.

  • Say hello! There’s lots you can learn from other stargazers. Why not come and see a Seasonal Night Sky show in the At-Bristol Planetarium before you head out into the wild? Our Live Science Team can tell you which constellations to look for throughout the year. The Bristol Astronomical Society is a friendly bunch of local astronomers, who meet weekly and are always happy to help those just starting out.

All set? Here are a couple of online resources to help you plan a stargazing adventure:

Remember, you can always ask us your stargazing questions below, on Facebook, or on Twitter and we'll do our best to answer them.  Have fun!

How to skate - some handy hints and tips!

Blogging science to life

Tue 31 December 2014, Written by: Nicole

It's under a week until we wave farewell to our lovely ice rink (sob!).

If you haven't taken to the ice yet, or alternatively if you want to perfect your technique for your final session, check out the pictures below from DK Superguides: Inline Skating 1996.

Start the new year with a 90s take on skating with style!

1. The A stance - a good steady stance to learn

The A stance

2. Regaining your balance - remember to lower your centre of gravity

Regaining balance

But should that fail...

3. Getting up! Steady yourself by placing your hands on your knee

Getting up!

Happy Skating!

Get crafty at After Hours...

Blogging science to life

Sat 7 December 2013, Written by: Heather

With only a few more days to go until our fantastically festive After Hours evening, we thought we'd help you get in the mood for some Christmas crafting with a little taster of what to expect on the night in Santa's Invention Workshop. Why not get hands-on and have a go at making these science-tastic tree decorations this weekend!

Light-up tree decorations

You will need:

  • Felt
  • 20cm piece of ribbon
  • Double-sided tape
  • LED bulb – you can easily find them in electronics stores or online
  • 3v cell battery (the type found watches)
  • 3 sticky foam circles
  • Strong glue or a needle and thread

What to do:

  • Dream up your unique decoration design – we recommend starting with something simple like a star, although other classic Christmas shapes work well too (trees, reindeer faces, puddings…)
  • Cut out the same shape on two pieces of felt
  • Test your LED. It will only light up when the longer of the two ‘legs’ is in contact with the positive side of the battery
  • Stick a foam pad slightly off-centre on one side of the battery
  • Slide the LED back on the battery - make sure it’s the correct way round
  • Stick the LED ‘legs’ in place using a foam pad on each side
  • Squeeze the foam pads to complete the circuit and light up the LED
  • Put your two shapes together to make a pocket, and pop the LED in the middle
  • Glue or stitch the shapes together around the edges
  • Use a hole punch or needle to thread your ribbon through the top

And voila! Your light-up decoration is ready to take pride of place on your tree this year.

If that's whet your appetite for some more Christmas creativity then our elves will be on hand on Monday evening to help you make some science-inspired stocking fillers as part of After Hours, our Christmas knees-up with a difference! Find out more and book your place here.
