23 of the best astronomy photographs that are out of this world
The winning images from this year's Astronomy Photographer of the Year have been announced. Baily's beads come from the specks of light that appear around the Moon during a total eclipse of the Sun, a phenomenon first explained by 19th Century astronomer Francis Baily. Yu Jun's picture is a multiple exposure, capturing the Sun during the stages of a total solar eclipse as seen from Luwuk, Indonesia. With more than 4, entries, Dr Kukula said this year they had been looking for out-of-the-ordinary images that pushed the boundaries of photography. The runner-up in this section was also a composite image.
Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye , binoculars , or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science , such as by monitoring variable stars ,  double stars ,  sunspots ,  or occultations of stars by the Moon  or asteroids ,  or by discovering transient astronomical events , such as comets ,  galactic novae  or supernovae in other galaxies. Amateur astronomers do not use the field of astronomy as their primary source of income or support, and usually have no professional degree in astrophysics or advanced academic training in the subject. Most amateurs are hobbyists , while others have a high degree of experience in astronomy and may often assist and work alongside professional astronomers. Amateur astronomers typically view the sky at night, when most celestial objects and astronomical events are visible, but others observe during the daytime by viewing the Sun and solar eclipses.
