... 2010 November 3 . The Necklace Nebula . ... The newly discovered example of a ring-shaped planetary nebula is about 15,000 light-years distant. ... Astronomers estimating the apparent age of the ring to be around 5,000 years, also find more distant gas clouds perpendicular to the ring plane, seen here at the upper left and lower right. Those clouds were likely ejected about 5,000 years before the clouds forming the necklace. ... About APOD | ... NASA Web Privacy Policy and Important Notices . ...

So how do we find objects on the other side of the Universe? ... The latest instruments enable us to scan large areas of sky. Using Cerro Tololo's Blanco 4m telescope and the Canada-France-Hawaii 3.5 metre telescope , we are able to scan a piece of sky larger than the size of the moon every 5 minutes to a faintness level which allows us to find Type Ia supernovae halfway across the Universe. Type Ia supernovae are very rare - but each image we take contains 50000 galaxies. ...

. The Hubble Space Telescope's Advanced Camera for Surveys made these images, which directly show dusty disks around two stars. AU Microscopii (left) lies 32 light-years from Earth. HD 170146 is 88 light-years distant. The blue and red colors in the images provide the size of the dust particles. Blue indicates particles approximately 1/20,000mm in diameter, and red reveals particles 10 times larger, about 1/2,000mm across. NASA / ESA / STScI / JHU
