Latest Protoplanetary nebulae Stories
Astronomers using ESO’s Very Large Telescope in Chile have captured this eye-catching image of planetary nebula PN A66 33 — usually known as Abell 33.
The Boomerang Nebula, at a crisp one degree Kelvin (minus 458 degrees Fahrenheit), is the coldest known object in the Universe. In fact, the Boomerang Nebula is colder than the faint afterglow of the Big Bang, which is the natural background temperature of space.
NASA and the ESA reveal a Hubble Space Telescope image of a planetary nebula that resembles a Christmas ribbon.
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.
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.
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...
