Friends of APOD. The concept was popularized by Carl Sagan in his 1977 book The Dragons of Eden and on his 1980 television series Cosmos. If the stars are used, then the interval is called the sidereal day and is defined by the period between two passages of a star (more precisely of the vernal equinox, a reference point on the celestial sphere) across the meridian: it is 23 hours 56 minutes 4.10 seconds of mean solar time. This is the open cluster NGC 1746. Since 1995, images from the Hubble space telescope of the American space agency NASA have been published on the Astronomy Picture of the Day or APOD website. This was first devised about 432 bce by the astronomer Meton of Athens.
