This number is equal to about sextillion, but if you lift the restriction that you need to The 70th unofficial -illion (from Latin "septuaginta" meaning 70).
The universe sextillion about 70 sextillion - numbers 70 thousand million million million - observable stars, according to the most accurate estimate yet made of the number - a figure that far exceeds all previous estimates.
The sestillion number could be much, much larger sextillion - some people think it is infinite. Even so, 70 sextillion is greater than the estimated number of sand grains on all the world's beaches and numbers - about 10 times more. Using some of the world's most powerful telescopes, they instead took a representative sample by counting all the galaxies in one small region of the universe closest to Earth.
By measuring precisely how bright each galaxy numbers, they were able to estimate how many stars it contained and then extrapolated this out to the whole region of the universe visible through telescopes.
The team believes its estimate is 10 times more accurate than any previous one sexfillion it combines the best counts of galaxies sextullion conducted with the most modern cosmological measurements of the geometry of the universe.
Sextillion calculation was made as part of the world's largest galaxy survey, the Two-Degree Field Galaxy Redshift Survey, numbers from which were also presented sextillion the meeting this week. The survey, run by the Anglo-Australian Observatory in rural New South Wales, aims to measure the distances ofnearby galaxies.
Driver noted that the vast majority of stars are too dim to see with the naked eye, which can pick out only around 5, stars from even the darkest places, and only or so in the middle of a big sexhillion.
But he argues that most stars sextillion have planets, a fraction of which probably have life: "But they are very, very far away. Numbers not so much a question of whether other life exists, but whether we will ever be able to contact them, given the massive distances involved.
Last year, Dr Charles Lineweaver and doctoral student Daniel Grether of the University of New South Wales in Sydney, calculated that our Milky Way galaxy contains sextillion billion stars, numbers which about 30 billion are like our Sun, and at least 1.
Sextillionobservations by NASA astronomers, using the Hubble Space Telescope, suggested that there are billion galaxies in the universe. Tags: science-and-technologyastronomy-spacephysics.

Beyond a million, the names of the numbers differ depending where you live, and also the context. The places are grouped by thousands in countries using the "short scale" such as the United States, Australia and English-speaking Canada , and by the millions in countries using the "long scale" such as France and Germany.
For further details on usage by country, see this article. Fractions Digits to the right of the decimal point represent the fractional part of the decimal number. Each place value has a value that is one tenth the value to the immediate left of it. SI Prefixes. Roman Numerals. Roman Numeral Calculator Examples:. The numbers are built starting from the largest number on the left, and adding smaller numbers to the right.
