New Photo Reveals ‘Ghostly’ Green Nebula in Deep Space
An amazing new photo from a telescope in Chile has captured the most detailed view yet of a green glowing blob 3,300 light-years away from Earth.

The new image, released today (April 10) by the European Southern Observatory, shows the planetary nebula IC 1295 like it has never been seen before. This picture, which ESO scientists dubbed “ghostly,” marks the first time the nebula has been imaged such unprecedented detail.
“It has the unusual feature of being surrounded by multiple shells that make it resemble a microorganism seen under a microscope, with many layers corresponding to the membranes of a cell,” officials from the European Southern Observatory wrote in a statement.

An analemma is the figure “8″ loop that results when one observes the position of the sun at the same time during the day over the course of a year. Due to the earth’s tilt about its axis (23.45°) and its elliptical orbit about the sun, the location of the sun is not constant from day to day when observed at the same time on each day over the course of a full year. Furthermore, this loop will be inclined at different angles depending on one’s geographical latitude.
