Not only is it growing larger, but the edge of the universe is expanding at a faster and faster rate. Scientists think that the edge of the universe is expanding faster than the speed of light.What is the universe made of?Even though the Earth seems really big to us, it's actually a...

and space stretches. So, there’s our answer. The universe is expanding unto itself. That said, cosmologists are pushing the limits of mathematical models to speculate on what, if anything, exists beyond
Some seven billion years from now the Sun will start to develop into a red giant star, eventually becoming over a hundred times larger and a thousand times brighter than it is at present. The Earth's surface will be over 1,000 K. Subsequently the Sun will be subject to a series of ...
Bootes Void (Great Void, is a huge, spherical region of space that contains very few galaxies) - 250,000,000 light yearsThe Universe - 150,000,000,000 light years <This is the rough estimate of the size of the universe but it can be many times larger than the above-mentioned ...
So could it be that Earth really is unique? All living things on Earth are made of the same building blocks, long carbon-based molecules.所以地球真的是独一无二的吗？地球上所有的生物都有着相同的组成成分，即长碳基分子。Scientists now think that a large proportion of these molecules came from...
"The major difference between brown dwarfs and planets is their mass and the occurrence of deuterium — heavy hydrogen — burning," Nolan Grieves, a postdoctoral researcher in the University of Geneva Department of Astronomy, told Live Science via email. "At larger masses, an obje...
Largest moon: Ganymede, which orbits Jupiter, is roughly 3,273 miles (5,268 km) in diameter and is a little larger than the planet Mercury. Tallest mountain: Olympus Mons on Mars, roughly 15 miles (25 km) high and three times the height of Mount Everest on Earth. ...
leash pendant from Men In Black 2. And ours is just one contained within a much larger cluster of galaxies known, rather unimaginatively, as the Local Group. Don't let the centrist name fool you, this cluster contains around 50 galaxies and measures more than 10 million light-years across...
The biggest star in the universe (that we know of), UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti. ...
