Cosmic Evolution

The building site, dubbed “Sparky,” is a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate.

Scientists have collected seven rare, microscopic interstellar dust particles that date to the beginnings of the solar system.

NuSTAR has completed its 2-year-long primary mission, and has now been extended for an additional two years.

As planets cool, their lives may be extended by the presence of a companion.

An international team of researchers has devised a precise method for calculating the mass of galaxies.

Inside gas giants, carbon is crushed at pressures we could only imagine - that is, until the National Ignition Laboratory found a way to make it happen here on Earth.

New research shows the vital role of oceans in moderating climate on Earth-like planets.

A galaxy over 12 billion light years from Earth is running out of carbon dioxide gas, and headed for a ‘red and dead’ future.

NASA's new planet-cataloging mission is expected to detect more than 200 planets the size of Earths and super-Earths.

The average planetary orbit is ten times as elongated as Earths, a fact that can influence their potential habitability. Dim brown dwarfs may be part of the problem.
