The supernova is the result of the thermonuclear explosion of a white dwarf in the galaxy MCG-01-60-21 which is located some 300 million lightyears from Earth. For more information, follow the link in our bio. On July 5, 2006, the Swift observatory began observing supernova 2006dm a few days after its explosion.
The star's surface temperature is estimated at a scorching 140,000 degrees Celsius (250,000 degrees Fahrenheit). The origin of these cooler clouds within the nebula is still uncertain, but the streamers are clear evidence that their shapes are affected by radiation and stellar winds from the hot star at the center. The cool gas tends to lie in long streamers pointing away from the central star, and in a surrounding, tattered-looking ring at the outer edge of the nebula. Orange and red show the locations of cooler gas. 6 June 2022: Like Sherlock Holmess magnifying glass writ large, the NASA/ESA Hubble Space Telescope has been used to peer into an astronomical mystery in. Blue regions mark the hottest glowing gas, which forms a roughly circular ring around the central stellar remnant. The nebula shows several remarkable features. 04.16.15 - A green star marks the location of NASAs Curiosity Mars rover after a drive on the missions 957th Martian day, or sol, (April 16, 2015). A person born on this day will be 16 years old today. If you are trying to learn Japanese then this day of the week in Japanese is Kin'ybi. There were 359 days remaining until the end of the year. Our own Sun is predicted to create a planetary nebula some 6 billion years from now. 04.17.15 - Kepler Planet Candidates, January 2014. Januwas the 6 th day of the year 2006 in the Gregorian calendar.
The loss of the outer layers of the star into space exposes the hot stellar core, whose strong ultraviolet radiation then causes the ejected gas to fluoresce as the planetary nebula. They are shells of gas thrown off by stars of masses similar to that of our own Sun, when the stars are nearing the ends of their lives. Planetary nebulas are named after their round shapes as seen visually in small telescopes, and have nothing else to do with planets. Glowing in the constellation Aquila like a giant eye, the nebula is a cloud of gas ejected several thousand years ago from the hot star visible in its center. #Hubble30 (2000) The Hubble Space Telescope obtained this image of the strikingly unusual planetary nebula NGC 6751.
