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?

Astronomers were looking forward to the first high-res X-ray spectra from space, and all they would tell us about the cosmos. But unknown disaster seems to have befallen the Japanese satellite.

The universe looks very different with X-ray vision, revealing some of the most energetic interactions in our galaxy. Japan's new Hitomi telescope will help us see these wonders.
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.
Bye, Earth telescopes! You will never reach my level.
Ground-based telescopes are getting bigger and better while still being cheaper than space telescopes. But the vital scientific contributions made by Hubble demonstrates why we need both.
