Statins are a group of medicines that can help lower the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is often referred to as bad cholesterol, and statins reduce the production of it inside the liver.aving a high level of LDL cholesterol is potentially dangerous, as it can lead to a hardening and narrowing of the arteries (atherosclerosis) and cardiovascular disease (CVD) . CVD is a general term that describes a disease of the heart or blood vessels. It is the most common cause of death in the UK.
The colour of a star is primarily a function of its effective temperature. You should recall that a star approximates the behaviour of a black body radiator. As a black body gets hotter its colour changes. If you were to heat a solid shot put it would first emit radiation in the infrared region.
It's those zillions of electrons that you see, that make the stars shine - and that's what makes our Sun shine, too. The electrons give off all wavelengths of energy, so they give off not only light, but also heat. When a star runs out of hydrogen atoms, the helium atoms begin to join up and make carbon atoms. When the star runs out of helium atoms, the carbon atoms begin to join up and make oxygen, and so on until the heaviest element stars can make, which is iron. It takes a lot of energy to make these heavier atoms, so it can only happen inside stars, which make a lot of energy. The gravity of stars also pulled them together into groups, so that they formed into galaxies. Today there are about 1022 to 1024 stars in the universe (click here to find out what 1022 means). New stars are still being born every day (and old ones die).
