For example, a 6-ounce broiled porterhouse steak is a great source of proteinâabout 40 grams worth. But it also delivers about 12 grams of saturated fat. (3) For someone who eats a 2,000 calorie per day diet, thatâs more than 60 percent of the recommended daily intake for saturated fat.
As we learned in a previous video, there are 100 to 400 billion stars in the Milky Way and more than 100 billion galaxies in the Universe â maybe as many as 500 billion. If you multiply stars by galaxies, at the low end, you get 10 billion billion stars, or 10 sextillion stars in the Universe â a 1 followed by 22 zeros.
Because the universe was born 13.8 billion years ago, we can only observe objects up to a certain distance from Earth â light from more distant objects hasnât had time to reach us yet. To answer âhow many stars are there,â we must limit the discussion to what we can observe.Astronomers estimate that the observable universe has more than 100 billion galaxies. Our own Milky Way is home to around 300 billion stars, but itâs not representative of galaxies in general.The Milky Way is a titan compared to abundant but faint dwarf galaxies, and it in turn is dwarfed by rare giant elliptical galaxies, which can be 20 times more massive.ecause the universe was born 13.8 billion years ago, we can only observe objects up to a certain distance from Earth â light from more distant objects hasnât had time to reach us yet.
