With more and more of us living in built-up areas, it's becoming harder to see a star filled night sky.
And with light pollution becoming a bigger concern, it's a rare sight to see a clear sky above.
But there are huge swathes of Wales with some of the best dark skies in the world where you can stargaze all night.
Both the Snowdonia National Park and the Brecon Beacons National Park have been given a sought-after status .
They're part of a select club of 13 places in the world designated as Dark Sky Reserves.
The title is given by the International Dark Sky Association(IDA) to select destinations that have proven that the quality of their night sky is "outstanding" and real efforts are being made to reduce light pollution.
They said: "An IDA International Dark Sky Reserves a public or private land possessing an exceptional or distinguished quality of starry nights and nocturnal environment."
Reserves consist of a "core area" meeting minimum criteria for sky quality and natural darkness, with a surrounding area that supports dark sky preservation in the core.
Places can only become a dark sky reserve after a "rigorous" application process.
Brecon became a reserve in 2012 - the first in Wales.
On a clear night in the park you can see the Milky Way, major constellations, bright nebulas and even meteor showers.
The park said: "Through this highly prestigious status, we hope to preserve our magical night skies for future generations and help reduce carbon dioxide emissions in our Park. We also intend to help protect a whole host of nocturnal creatures that need dark nights to forage, hunt and migrate."
Based near Newport, photographer Allen Lloyd has photographed the area extensively, and offers astro-photography workshops and tuition.
In September 2015 Snowdonia became the 10th ever Dark Sky Reserve.
At the time, on behalf of the Dark Sky Institute Directors, John Barentine said: "Wales now leads the world in the percentage of its territory enjoying protected status for its night skies: as of today, these protections encompass nearly 18% of the Wales’ land area.
"Nowhere else has achieved comparable success in recognising the value of night time darkness and taking concrete steps to safeguard it for future generations."
