Fast-moving stars shed new light on how these distant galaxies, which are a fraction the size of our Milky Way, may have evolved into the full-grown galaxies seen around us today.

NASA's Hubble Space Telescope has taken the sharpest visible-light picture yet of atmospheric debris from an object that collided with Jupiter on July 19.
In tribute to Hubble's longest-running optical camera, a planetary nebula has been imaged as WFPC2's final "pretty picture."
Hubble is getting closer to completing the calibrations for most of its instruments, and each day it draws nearer to becoming a fully functioning observatory again. In fact, in the upcoming weeks, Hubble will concentrate on making high-priority science observations and then finish the remaining instrument calibrations by early fall.
As the first week of August comes to a close, most of Hubble’s science instruments have already completed or are close to completing their calibration activities. Each instrument has multiple channels that detect different wavelengths of light, and each channel must be tested and calibrated individually. While some instrument channels are still under evaluation, several others are already at work studying the universe.
Hubble engineers are encouraged by the recent restart attempt of an instrument that has been inoperable since Sept. 10, 2008.
The HST tiger team continues their investigation of a problem with the Space Telescope Imaging Spectrograph (STIS) that caused it to suspend operations on July 6.
Unlike on many previous NASA space science missions, anyone can apply for observing time on the Hubble Space Telescope.
When astronauts return to Hubble for Servicing Mission 4 in 2009, they will be revamping and reenergizing the telescope for the final leg of its journey. One of the tasks they aim to complete is the installation of New Outer Blanket Layers, or NOBLs.
When astronauts visit the Hubble Space Telescope in 2009 for its final servicing mission, they will be facing a task that has no precedence – performing on-orbit 'surgery' on two ailing science instruments that reside inside the telescope.
The work of American astronomer Edwin Powell Hubble revolutionized our understanding of the size and structure of the universe.
Thanks in part to the Hubble Space Telescope, we know the universe is 13.7 billion years old.
Nearly all galaxies may harbor supermassive black holes.
The Hubble Space Telescope has helped scientists determine the process of how planets are born.
The Hubble Space Telescope detected the first organic molecule discovered on a planet outside our solar system.
The Hubble Space Telescope detected a distant supernova that suggests the universe only recently began speeding up.
