Imagined view from the surface of one of the newly discovered planets, with ultracool dwarf star TRAPPIST-1 in the background.
We don't need to look for Earth-like planets exclusively around Sun-like stars. Tiny, dim TRAPPIST-1 has only 11 percent the diameter of the Sun and is much redder.

A giant golden mirror is on the brink of opening up a glimpse of the very first galaxies to be formed.
Bigger but not better than Hubble. The James Webb’s primary mirror.
It's urgent that we turn our attention to a high definition space telescope that will allow us to directly image exoplanets.
The James Webb Space Telescope will search for stars in the dawning universe.
When the Obama administration announced its proposed NASA budget in February, astronomers worldwide breathed a sigh of relief. Despite significant cuts in other areas, funding for the James Webb Space…
Does the US suffer from its desire to go it alone in space?
In its newly released budget request to Congress, the Obama Administration is seeking to reduce NASA’s funding by US$59m to US$17.7 billion – a reduction of just 0.03%, not that you would know that from…
