| Stargazing, or astronomy, is the study and enjoyment of the stars. Actually, it's not just about stars - other objects visible in the night sky include galaxies (groups of billions of stars); planets (which orbit stars); and other rocky things flying around in space, like asteroids (chunks of rock in orbit around stars - there' | Stargazing, or astronomy, is the study and enjoyment of the stars.

| Dating back to prehistory, it’s perhaps the oldest of the natural sciences and was originally closely interwoven with religious, mythological and cosmological beliefs and practices.

| In the 1960s, scientists also began to look for evidence of alien life. Certain sugar molecules have been discovered in distant clouds of gas and dust that have the potential to create the basic building blocks of DNA; and there are potentially hundreds or thousands of planets with the conditions required to support life in our galaxy alone. Although nothing has been found so far (and at our level of technology, our attempts can only reach a relatively tiny distance), the search for alien life and other inhabitable planets is very much a part of modern astronomy, and astrobiology. Maybe we won’t be alone for much longer (but then there' | In the 1960s, scientists also began to look for evidence of alien life.

| It's easier to see stars if it's not a full moon (and the newer the better), and you're away from artificial lights. Don’t be put off completely if you live in a city or an area with a lot of light pollution, however. While everyone should experience the breathtaking sight of stars in a really dark sky at least once in their lifetime (the UK has a few ‘dark parks’ where you can do this - see [Dark Sky](http:// | It's easier to see stars if it's not a full moon (and the newer the better), and you're away from artificial lights.

| Stargazing is a very safe activity, but if you’re going to be spending time outdoors at night then make sure you’re well wrapped up, have sufficient food, water and a fully-charged phone. Also, let someone know where you’re going and make sure you don’t fall into any holes while you’re gazing up at the sky. | Stargazing is a very safe activity, but if you’re going to be spending time outdoors at night then make sure you’re well wrapped up, have sufficient food, water and a fully-charged phone.
