The melting of materials seems like a simple phenomenon. However, when their thickness is reduced to just a few atoms, ...

From science-fiction technologies like warp drives and levitation to the search for evidence of intelligent life elsewhere in ...

An object spotted in deep space is the strongest candidate yet for a galaxy arrested during early development.

For more than a century, schoolbook physics has divided matter into neat categories like solid, liquid, gas, and plasma. A ...

The universe is packed with riddles, but few are as stubborn or as fascinating as dark matter. First proposed in 1933 by astronomer Fritz Zwicky, this elusive substance refuses to play by the rules: ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

Matter is all around us. Everything that has weight and takes up space is matter. Matter exists mostly in four basic states: solid, liquid, gas, and plasma. And it all has to do with atoms. Science ...

Fish school, insects swarm and birds fly in murmurations. Now, new research finds that on the most basic level, this kind of group behavior forms a new kind of active matter, called a swirlonic state.

In middle and high school, most people learn about the three states of matter we interact with in our everyday lives: solid, liquid and gas. Some students may have even been introduced to the idea of ...

At the end of a lecture on astronomy, describing how the planets orbit the Sun, a little old lady at the back of the room stood up and said: "What you've told us is all rubbish. The world is really a ...

Dark matter, it seems, has been clinging to galaxies for a very long time. Most galaxies that existed 10 billion years ago had about as much dark matter as galaxies do today, contradicting earlier ...

Only recently have scientists realized that most of the universe is neither gaseous, liquid or solid. It is plasma, a lively, tricky, often dangerous state of matter whose distinctive characteristic ...
