How many galaxies does the Milky Way have? “There are around fifty galaxies in the Milky Way, the largest of which is the Large Magellanic Cloud. This satellite galaxy has a diameter of only 14,000 light-years. The Large Magellanic Cloud may...
How many Milky Ways are there in space? “This tiny patch of sky was full of galaxies, almost 10,000, of all different sizes and shapes. By multiplying this number by the number of times this tiny patch of sky would fit...
Can a galaxy have multiple suns? “Millions of two-sun planets in our galaxy alone, study suggests. Hot on the heels of a report that says worlds with two suns can be Earthlike, a new study suggests our galaxy alone holds millions...
How many Earths can the Milky Way hold? “Plugging in our thickness and radius we get about 6.7 X 10^(51) km^3. Dividing the volume of the Milky Way by the volume of the Earth, you get (6.7 X 10^(51))/(10^12) =~ 6.7...
How many Earths are in the universe? “This means that about one in six stars has an Earth-size companionexoplanet. As there are about 100 billion stars in the galaxy, there are at least 17 billion Earth-size worlds in this galaxy alone....
In which galaxy is TON 618 located? “This is considered one of the highest masses ever recorded for such an object; higher than the mass of all stars in the Milky Way galaxy combined, which is 64 billion solar masses, and...
How large is TON 618 today? “TON 618 is an extremely bright quasar in the constellation of Canes Venatici, 18.2 billion light-years away. It contains the largest, brightest and most massive black hole known. It is 66 billion times more massive...
How big is TON 618 now? “TON 618 is an extremely bright quasar in the constellation of Canes Venatici, 18.2 billion light-years away. It contains the largest, brightest and most massive black hole known. It is 66 billion times more massive...
Can you see TON 618 from Earth? “Due to the brilliance of the central quasar, the surrounding galaxy is outshone by it and hence is not visible from Earth.” Can TON 618 swallow our solar system? “TON 618 is ~2600 AU...
How many Earths could fit inside TON 618? “And now, we divide the volume as TON 618’s Schwarzschild radius by the volume of Earth: So there you go: you could fit approximately 26,000,000,000,000,000,000,000 Earths into the same volume of TON 618’s...
