Lee Rannals for redOrbit.com – Your Universe Online NASA and the European Space Agency (ESA) have released a new Hubble Space Telescope image of the planetary nebula NGC 5189. In the essence of the Christmas spirit, ESA describes the cosmic structure of the eruption as a "giant and brightly colored ribbon in space." The structure visible within NGC 5189 is particularly dramatic, and the space agencies said the image is the most detailed yet image of this object. Planetary...
The NASA/ESA Hubble Space Telescope has been at the cutting edge of research into what happens to stars like our sun at the ends of their lives. One stage that stars pass through as they run out of nuclear fuel is called the preplanetary or protoplanetary nebula stage. This Hubble image of the Egg Nebula shows one of the best views to date of this brief but dramatic phase in a star’s life. The preplanetary nebula phase is a short period in the cycle of stellar evolution, and has nothing...
NASA -- The Hubble Space Telescope has "caught" the Boomerang Nebula in these new images taken with the Advanced Camera for Surveys. This reflecting cloud of dust and gas has two nearly symmetric lobes (or cones) of matter that are being ejected from a central star. Over the last 1,500 years, nearly one and a half times the mass of our Sun has been lost by the central star of the Boomerang Nebula in an ejection process known as a bipolar outflow. The nebula's name is derived from...

Hourglass Nebula -- This is an image of MyCn18, a young planetary nebula located about 8,000 light-years away, taken with the Wide Field and Planetary Camera 2 (WFPC2) aboard NASA's Hubble Space Telescope (HST). This Hubble image reveals the true shape of MyCn18 to be an hourglass with an intricate pattern of "etchings" in its walls. This picture has been composed from three separate images taken in the light of ionized nitrogen (represented by red), hydrogen (green), and doubly-ionized...
Boomerang Nebula -- The Boomerang nebula, also called the bowtie nebula since the Hubble space telescope revealed more detail, located 5,000 light-years from Earth,in the constellation Centaurus. The Boomerang Nebula is one of the Universe's peculiar places. In 1995, using the 15-metre Swedish ESO Submillimetre Telescope in Chile, astronomers Sahai and Nyman revealed that it is the coldest place in the Universe found so far. With a temperature of -272 degrees C, it is only 1 degree...
