What are stars made of? What is the brightest star in the constellation Orion? What are the major stars in the constellation Pegasus? How massive are the largest known galaxies? What are the names of the stars i
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...
discovered what may be the largest black hole known to date.The black hole has a mass (量) of about 30 billion suns and sits at the center of a galaxy(星系), which is hundreds of millions of light-years from the Earth.Black holes are one of the most powerful forces in the universe...
in a 2012 paper in the journalSolar and Stellar Astrophysics. This red hypergiant star was once estimated to be 1,800 to 2,200 times the width of the sun, but new measurements brought it down to size. However, some sources still list it as the largest star. ...
A cooling, expanding Universe that has billions of years to form stars, galaxies and clusters of galaxies on the largest scales also has the extraordinary property that as we look farther away at greater distances in the Universe, we also see back in time. When we look at galaxies and ...

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...
Its 500-metre dish is the world’s largest single-dish radio telescope. Scientists can use it to search for signals of communication that are not coming from the earth. If scientists find such things, maybe there is life somewhere else in the universe!What is Shenzhou-16?Shenzhou-16 manned...
There are three different main shapes of galaxies that exist in our universe. The one you are probably most familiar with are spiral galaxies, like our Milky Way, which have two or more arms spiraling around a center core. Then there are the elliptical galaxies which have egg-like ...
Around 15% to 20% of galaxies with AGNs are bright in radiowaves and are classed as being "radio loud," according to the California Institute of Technology (Caltech). Quite what makes one AGN "radio loud" and another "radio quiet" is not currently fully understood, as the emissions of...
