Spectacular NASA Astronomy Pictures of the Week: Eagle Nebula, Dark Sunspots and more
NASA Cat’s Eye Nebula
1/5 The mesmerizing Eagle Nebula (May 15) - This is a snapshot of M16, also known as the Eagle Nebula which spans about 20 light-years across. The nebula, discovered in 1745 by the Swiss astronomer Jean-Philippe Loys de Chéseaux, is located 7,000 light-years from Earth in the constellation Serpens, according to NASA. (NASA/Gianni Lacroce)

2/5 Sun’s Corona visible during solar eclipse (May 16) - Sun’s Corona was shot during a total solar eclipse. Temperatures in the Sun’s Corona can reach up to 2 million degrees and it is also the region where solar wind originates, according to NASA. While the hottest part of the Sun is its core, one of its most puzzling features is its Corona which extends more than 1 million kilometers from its surface. (NASA/Reinhold Wittich)

3/5 Sun’s Dark Sunspots (May 17) - Sunspots on the surface of the Sun in the active region AR 3297 were captured in this image. According to NASA, Sunspots are dark areas on the solar surface that contain strong magnetic fields that are constantly shifting and can form and dissipate over periods of days or weeks. They occur when strong magnetic fields emerge through the solar surface and allow the area to cool slightly. (NASA/Mark Johnston)

4/5 Breathtaking WR134 Ring Nebula (May 18) -  It is a breathtaking snapshot of the WR134 Ring Nebula, located about 6000 light-years from Earth towards the constellation Cygnus. At the center of the Nebula is the Wolf Rayet star WR 134 named after French astronomers Charles Wolf and Georges Rayet. (NASA/Craig Stocks)

5/5 Snapshot of M63 Curly Spiral Galaxy (May 19) - The celestial object captured in this image is the M63 Curly Spiral Galaxy which is located about 30 million light-years away towards the constellation Canes Venatici. Also known as NGC 5055, this spiral galaxy spans almost 100,000 light-years. Spiral Galaxies like M63 are disks of stars, gas, and dust that have bright bulges in their centers made up primarily of older and dimmer stars. (NASA/Sophie Paulin/Jens Unger/Jakob Sahner)

NASA's Astronomy Picture of the Day is published on a daily basis and the US space agency showcases photographs of celestial objects captured by astrophotographers from all over the world. NASA also snaps objects in space using its advanced technology such as the Spitzer Space Telescope, the Hubble Space Telescope, the James Webb Space Telescope and other observational assets. In fact, the newly launched James Webb Telescope has enabled NASA to observe and study objects located millions of light-years away in space, much further than the veteran Hubble Telescope. However, while these big guns are in constant use by NASA, the agency also keeps an eye on what lay astrophotographers around the world are doing in order to highlight the images they took too.

Today's NASA Astronomy Picture of the Day is a snapshot of the NGC 6543, also known as the Cat's Eye Nebula located about 3000 light-years away. According to NASA, the Cat's Eye Nebula is one of the best-known planetary nebulae in the sky and its faint outer halo spans about 5 light-years. NGC 6543 is located towards the constellation of Draco and was discovered by German-British astronomer William Herschel on February 15, 1786.

This breathtaking picture was captured by astrophotographers Jean-Francois Bax and Guillaume Gruntz.

NASA's description of the picture

The Cat's Eye Nebula (NGC 6543) is one of the best-known planetary nebulae in the sky. Its more familiar outlines are seen in the brighter central region of the nebula in this impressive wide-angle view. But this wide and deep image combining data from two telescopes also reveals its extremely faint outer halo. At an estimated distance of 3,000 light-years, the faint outer halo is over 5 light-years across.

Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. More recently, some planetary nebulae are found to have halos like this one, likely formed of material shrugged off during earlier episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the age of the outer filamentary portions of this halo to be 50,000 to 90,000 years. Visible on the right, some 50 million light-years beyond the watchful planetary nebula, lies spiral galaxy NGC 6552.
