Pictures from the Hubble Telescope

Carina Nebula
Don't feel bad if your digital camera can't quite capture this type of imagery. This photo of the central region of Carina Nebula is a mosaic of 48 frames taken during March and July 2005 with Hubble's Advanced Camera for Surveys and Cerro-Tololo Interamieracn Observatory's Blanco Telescope and MOSAIC2 camera. What you see is an artist's impression of a giant planet passing in front of its parent star, also known as a transit.


Aquarius
See that little white dot at the center of the image? That's a White Dwarf Star, also known as a dead star, that is 650 light-years away and, apparently, refusing to burn out peacefully. The colorful gaseous material was once part of the star. The image is a composite from Hubble (visible data) and the Spitzer Space Telescope (infrared data).


Bug Nebula
This ethereal image, taken in 2004, shows us the Bug Nebula's dusty surroundings near the heart of the brighter inner nebula in the upper right. A star, hidden by dust, exists in the inner nebula but has never been seen. But we know it's there and it generates a not-so-comfortable temperature of at least 250,000 degrees C.



Eskimo Nebula
The Hubble captures this luminous view of a planetary nebula. It was nicknamed the Eskimo Nebula because when seen through a ground-based telescope it resembled a fur parka hood surrounding a face. The 'parka' is actually a ring of comet-shaped objects streaming away from the dying star at its center.


Sombrero
M 104, the Sombrero Galaxy, is a bright white core surrounded by round thin spiral arms. This galaxy is 50,000 light-years across and a mere 28 million light-years from where you're sitting right now. By the way, light travels at the grandmotherly pace of 186,000 miles per second.


Hubble Telescope: Tendrils
What's taking place here is a gathering of thick clumps and tendrils of interstellar hydrogen that are in the process of forming stars. Bet you never thought a planet could be made of gas. In fact, hydrogen is the primary component of Jupiter, the largest planet in the Solar System.


Van Gogh
In what has been described as "space phenomenon imitates art", variable star V838 Monocerotis is surrounded by walls of swirling interstellar dust. The Hubble image has been compared to "Starry Night", the painting by Dutch post-impressionist Vincent van Gogh. A variable star changes in brightness over time. V838 is 20,000 light years away.
