Cosmic Evolution

Astronomers using the Hubble Space Telescope have captured the most comprehensive picture ever assembled of the evolving Universe — and one of the most colorful.

A new series of measurements provides evidence that the Moon formed from the collision of the Earth with another large, planet-sized body, around 4.5 billion years ago.

A new instrument installed on ESO’s Very Large Telescope (VLT) at the Paranal Observatory in Chile has achieved first light.

Life in our Universe may be rarer than we thought.

Scientists look at moon’s lopsided shape and how it changes under Earth’s sway – a response not seen from orbit before.

New research following up on the Kepler discoveries shows that exoplanets can be divided into three groups -- terrestrials, gas giants, and mid-sized "gas dwarfs"

For the first time, astronomers have predicted the 'time of death' for two exoplanets.

A new model is helping astronomers identify Sun-like stars that have ‘ingested’ the Earth-like planets that once orbited them.

The Solar System is just one possible outcome of planet formation and it might be an unusual case.

Today’s hunt for exomoons is defined by what Kepler can see and by models of satellite formation in our own Solar System.
