A planet in a triple-star system has been discovered.
Publicly available data and collaborations between scientists have led to the discovery of a planet in a triple-star system.
On Dec. 21, Jupiter and Saturn will be so close together they will almost appear to be touching.
From the birth of Jesus Christ to Newton's discovery of gravity, great conjunctions of Jupiter and Saturn have many notable connections in human history.

Sometimes it is difficult to take a photograph of an exoplanet because the star illuminating it is too bright. Now there is a new 'deluminator' telescope that can block out the extra light.

New research does away with dark matter by putting 'entropy', a measure of disorder, at the heart of the universe.
NASA’s Transiting Exoplanet Survey Satellite (TESS) successfully launched on a SpaceX Falcon 9.
The new planet-hunting telescope TESS was successfully launched today by NASA, and Australia will play a key role in checking out any new worlds it discovers.

When NASA first started planning the Kepler mission, no one knew if the universe held any planets outside our solar system. Thousands of exoplanets later, the search enters a new phase as Kepler retires.
An artist’s concept of select planetary discoveries made to date by NASA’s Kepler space telescope.
The number of known exoplanets doubled this week to more than 3,200. But why have only a handful of these those new planets caught people's imagination?

The increasingly rapid pace of exoplanet discoveries must mean it is only a matter of time until astronomers find another Earth.
It's regarded as a Biblical myth, but what the magi are supposed to have seen is rooted in astronomy.
