The brilliant tapestry of young stars flaring to life resemble a glittering fireworks display in this 25th anniversary NASA Hubble Space Telescope image to commemorate a quarter century of exploring the solar system and beyond since its launch on April 24, 1990.

The sparkling centerpiece of Hubble's silver anniversary fireworks is a giant cluster of about 3,000 stars called Westerlund 2, named for Swedish astronomer Bengt Westerlund, who discovered the grouping in the 1960s. The cluster resides in a raucous stellar breeding ground known as Gum 29, located 20,000 light-years away from Earth in the constellation Carina.

To capture this image, Hubble’s Wide Field Camera 3 pierced through the dusty veil shrouding the stellar nursery in near-infrared light, giving astronomers a clear view of the nebula and the dense concentration of stars in the central cluster. The cluster measures between 6 to 13 light-years across.

The giant star cluster is only about 2 million years old and contains some of our galaxy's hottest, brightest, and most massive stars. Some of its heftiest stars unleash torrents of ultraviolet light and hurricane-force winds of charged particles that etch at the enveloping hydrogen gas cloud.

The nebula reveals a fantasy landscape of pillars, ridges, and valleys. The pillars, composed of dense gas and thought to be incubators for new stars, are a few light-years tall and point to the central star cluster. Other dense regions surround the pillars, including reddish-brown filaments of gas and dust.

Hubble Observes Comet Siding Spring Flyby of Mars

On October 19th, the +Hubble Space Telescope was pointed at the planet Mars to view a close flyby of Mars by Comet Siding Spring.  The comet passed by Mars at approximately 87,000 miles (about one-third of the distance between Earth and the Moon). At that time, the comet and Mars were approximately 149 million miles from Earth.

Please watch our #Hubble Hangout today at 3pm EDT with +Tony Darnell members of the team that took the images.

Can I retroactively make this image the cover image of my thesis?
Prometheus is caught in the act of creating gores and streamers in the F ring. Scientists believe that Prometheus and its partner-moon Pandora are responsible for much of the structure in the F ring.

The orbit of Prometheus (53 miles, or 86 kilometers across) regularly brings it into the F ring. When this happens, it creates gores, or channels, in the ring where it entered. Prometheus then draws ring material with it as it exits the ring, leaving streamers in its wake. This process creates the pattern of structures seen in this image.

This view looks toward the sunlit side of the rings from about 8.6 degrees above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 11, 2014.

The view was acquired at a distance of approximately 1.3 million miles (2.1 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 147 degrees. Image scale is 8 miles (13 kilometers) per pixel.

Most Colorful Hubble Ultra Deep Field Yet

Here is what happens you observe the same area of sky with more and more wavelengths.

This is an image of the Ultra Deep Field, originally taken in 2003 and subsequently added to over the years.  This year, we added ultraviolet.

Ultraviolet light comes from the hottest, largest, and youngest stars. By observing at these wavelengths, researchers get a direct look at which galaxies are forming stars and where the stars are forming within those galaxies.

You can learn more about and download this image along with a video from our website:

I'll be talking about moons tomorrow night.
Hubble Public Lecture Series is hosted by Dr. +Frank Summers and presented the first Tuesday of every month at 8pm Eastern Time (12am GMT).  They are open to all and available on YouTube Live.

This month's speaker is Dr. +Bonnie Meinke an astronomer at the Space Telescope Science Institute.

Earth's Moon is so familiar to us, yet there are hundreds of other moons in our solar system that still remain exotic.
Take a journey from our Moon to the weird and wonderful collection of moons across interplanetary space. Explore volcanoes, oceans, and clouds that make these distant worlds much more recognizable than one might have guessed. And consider how these familiar geologic features could create ideal conditions for life to take hold and flourish!

Please join us and we will also try to answer any questions during the talk.

Today at #SciFest 2014

We had a very busy day talking with people about the Hubble Space Telescope along with a variety of topics related to light and colors.  If you haven't had a chance to visit our booth, we'll be there again tomorrow, stop by and say hi and we'll have astronomers standing by to discuss all sorts of things about our universe
