Celestial Fireworks: Star Cluster Westerlund 2

The nebula Gum 29 is a star-forming region about 20,00 light-years away in the constellation Carina. At the core of the nebula is a cluster of several thousand stars called Westerlund 2. These newborn stars are approximately 2 million years old, and their light illuminates, heats, and erodes the surrounding gas. The Hubble image, utilizing both visible and infrared light observations, was released in celebration of the telescope’s 25th anniversary.... Read More إقرأ المزيد | Share it now!

Flight to Star Cluster Westerlund 2

This visualization provides a three-dimensional perspective on Hubble’s 25th anniversary image of the nebula Gum 29 with the star cluster Westerlund 2 at its core. The flight traverses the foreground stars and approaches the lower left rim of the nebula Gum 29. Passing through the wispy darker clouds on the near side, the journey reveals bright gas illuminated by the intense radiation of the newly formed stars of cluster Westerlund 2. Within the nebula, several pillars of dark, dense gas are being shaped by the energetic light and strong stellar winds from the brilliant cluster of thousands of stars. Note that the visualization is intended to be a scientifically reasonable interpretation and that distances within the model are significantly compressed.... Read More إقرأ المزيد | Share it now!

Hubble 25th Anniversary Series – The Incredible Time Machine

With about a million observations under its belt during its 25 years of service, some of the Hubble Space Telescope’s most memorable images have been of the vastness of space and the early days of the universe. These “deep-field” images actually improved over the years because shuttle astronauts were able to upgrade the observatory. This episode, entitled “The Incredible Time Machine” shows us how Hubble has been able to give us a glimpse of a cosmos in its formative years.... Read More إقرأ المزيد | Share it now!
