The launch of Hubble Space Telescope on April 24, 1990. This photo captures the first time that there were shuttles on both pad 39a and 39b.
Thirty years ago the Hubble Space Telescope began snapping photos of distant stars, providing a time machine that has taken astronomers back to when the universe was less than a billion years old.
An enhanced image of galaxy clusters.
New research using the Hubble Space Telescope reveals that galaxies may be forming at faster rates than previously believed.
Is there anybody out there?
From the subatomic to the cosmic, don't think for a second that we're at the end of scientific history.
Kepler 452-b is looking like a good candidate for having evolved life.

Life could have evolved on exoplanets Kepler-452b and Kepler-62e, according to a new study.
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.
The light shining through an exoplanet’s atmosphere can give us a hint of whether the planet supports life.

A hint of oxygen and a whiff of methane in a distant exoplanet's atmosphere may be the first evidence we discover of alien life.
Images of galaxies far away may be forever blurred – no matter how big the telescope.
Telescopes are getting larger and larger as astronomers are hoping to get a good view of the most distant objects in space. But, it turns out, bigger isn't always better.
Gilt-edged. The James Webb telescope steps up the search.

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…
