The term complex carbohydrate was first used in the U.S. Senate Select Committee on Nutrition and Human Needs publication Dietary Goals for the United States (1977) where it was intended to distinguish sugars from other carbohydrates (which were perceived to be nutritionally superior).
The SMBH at the centre of the Milky Way is of 4.1 million solar mass, whereas the nearby Andromeda Galaxy contains a SMBH of 110-230 million solar mass. The largest SMBH in the Milky Way's vicinity appears to be that of the galaxy M87, containing 6.4 billion solar mass. The largest SMBH in the nearby Universe yet found is that of the galaxy NGC 4889, containing 21 billion solar mass.
Each big object in space is part of a much larger structure - the large-scale structure of the visible universe. We only see a minuscule piece of the universe. Big is bigger than we can ever imagine. VY Canis Majoris is the biggest type of star known as a red hyper giant. It is 4,892 light years from Earth and has a circumference of 5.46billion miles - around 2,000 times that of our sun. It would take a passenger jet 1,100 years to fly round it once.
