Our Galaxy galaxy will undoubtedly endure in its present kind of bit longer than some astronomers had believed, a new research study suggests. A view of the Andromeda galaxy, also known as M31, with measurements of the motions of stars within the galaxy. This spiral galaxy is the nearest large neighbor of our Milky Way. (Image...

The fall of a blue ultra-diffuse galaxy into a galaxy system and its subsequent ejection as a red ultra-diffuse galaxy.

By definition, dwarf galaxies are tiny and dim, with just a fraction of the stars located in the Milky...
How unusual is our Solar System? In about 30 years since planets were first discovered orbiting stars besides our Sun, we have found that planetary systems are prevalent in the Galaxy. However, most of them are pretty different from the Solar System we know. The worlds in our Solar System revolve around the Sun in...

He lived in a very wooded area, with trees filling his neighborhood, which was very fortunate since he loved to play in the forest. However, one of the saddest events of his...
Wind, solar, geothermal, hydro, wave power… Sustainable resources are an essential pillar of any strategy to decarbonize the planet's power generation sectors and eradicate fossil fuel usage. However, for several factors – intermittency, location dependence, land needs, and others – they can not accomplish it independently. A scalable form of zero-emissions energy that can reliably...

Vega is the fifth brightest star, excluding the sun, that can be seen from Earth. (Image credit: NASA/JPL-Caltech) A possible searing-hot planet was spotted by astronomers, orbiting Vega, one of the brightest and most known stars in the sky. Approximately the size of Neptune, the candidate alien planet lies very close to Vega, taking 2.5 Earth...
