Science:<\/strong><\/span>  Stars, like the Sun, are giant nuclear reactors.&nbsp;&nbsp;Stars are giant spherical balls of gas, mostly made of hydrogen.&nbsp;&nbsp;Deep in the centre, at extremely high temperatures, stars are fusing hydrogen and making helium.&nbsp;This process generates all of the heat and light that comes from stars, including our Sun.&nbsp;&nbsp;The Sun is about 6000 degrees Celsius on the surface and is yellow in colour.&nbsp;&nbsp;The colour of a star is related to its surface temperature; hot stars can be more than 10,000 degrees on the surface and look blue in colour, cool stars are roughly 3,000 degrees on the surface and appear red in colour.&nbsp;&nbsp;This colour variation is the opposite way around to the taps in a bathroom \u2013 the hot tap is red, while the cold tap is blue!&nbsp;&nbsp;Star also come in different sizes.&nbsp;&nbsp;Cooler, red stars are generally very small compared to the Sun, and are often very faint.&nbsp;&nbsp;Bluer, hotter stars are much larger than the Sun in size and can be many thousands of times brighter than the Sun.&nbsp;&nbsp;On the sky, the brightness of a star depends on how bright the star is, but also how close it is \u2013 some stars are nearby, others are much further away.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"639\" height=\"360\"
