Who named the star Vega? What is the largest star in our galaxy? What is the brightest star in Canis Major? What astronomer discovered dark matter in spiral galaxies? Who discovered the Scorpius constellation? Stars that are much larger than the sun are called what?
planets, stars, asteroids, comets, gas, dust and more. Our ownMilky Way, if considered as one object, is about 100,000light-yearsacross. Scientists struggle to characterize the largest galaxies, because they don't really have precise boundaries, but the largest galaxies we know of are million...

is stretched longer along one axis than the other. They consist of around one trillion stars but very little dust. These stars are generally older or evolved stars. In elliptical galaxies the stars orbit in random directions along a common center. The largest known galaxies are of this shape....
The largest known Galaxy is IC 1101, discovered by Sir William Herschel There are four main types of galaxies (Spiral, Lenticular, Elliptical, Irregular)Galaxy's centre? No one knows for sure. Some say it is a super-star, a collection of bright stars or a super-black hole. The centre ...
While red supergiants are thelargest stars, each with a radius between 200 and 800 times the radius of our Sun, blue supergiants are decidedly smaller. Most are less than 25 solar radii. However, they have been found, in many cases, to be some of themost massivein the universe. (It'...
The largest galaxies can be seen in almost any telescope, under the right conditions. For example, my first successful photograph of theAndromeda Galaxywas captured using a compact refractor telescope with an 80mm aperture. However, viewing galaxies through the eyepiece of a telescope like this is...
Decades earlier, in 1929, astrophysicist Sir James Jeans theorized that the bright centers of galaxies might act as “white holes,” funneling matter into our universe from another dimension. However, we now know the reality is the opposite. Quasars are powered by supermassive black holes that ...
What is the surface temperature of Polaris? What kind of star is Arcturus? What is the approximate declination of Polaris, the North Star? What is the largest star cluster in our galaxy? What is the Butterfly Nebula? What are the stars in the constellation Orion?
