Telescopes catch-up with Hubble
By Dr David Whitehouse
Move over the Hubble Space Telescope (HST). Ground-based devices have
been catching up in the 13 years since the famous space observatory was
launched.
The new Gemini telescopes, equipped with advanced instruments, are
producing images of deep space that rival the HST's.
The Gemini Observatory comprises two large telescopes - one in the
Northern Hemisphere and one in the South. Their new imaging spectrograph
recently captured images that are among the sharpest ever obtained from
the ground.
One Gemini image reveals remarkable details, previously only seen from
space, of a group of galaxies located about 400 million light-years
away.
