Explanation: Young suns still lie within dusty NGC 7129, some 3,000 light-years away toward the royal constellation Cepheus. While these stars are at a relatively tender age, only a few million years old, it is likely that our own Sun formed in a similar stellar nursery some five billion years ago. Most noticeable in the sharp image are the lovely bluish dust clouds that reflect the youthful starlight. But the compact, deep red crescent shapes are also markers of energetic, young stellar objects. Known as Herbig-Haro objects, their shape and color is characteristic of glowing hydrogen gas shocked by jets streaming away from newborn stars. Paler, extended filaments of reddish emission mingling with the bluish clouds are caused by dust grains effectively converting the invisible ultraviolet starlight to visible red light through photoluminesence. Ultimately the natal gas and dust in the region will be dispersed, the stars drifting apart as the loose cluster orbits the center of the Galaxy. The processing of this remarkable composite image has revealed the faint red strands of emission at the upper right. They are recently recognized as a likely supernova remnant and are currently being analyzed by Bo Reipurth (Univ. Hawaii) who obtained the image data at the Subaru telescope. At the estimated distance of NGC 7129, this telescopic view spans over 40 light-years.

Your Charm for Today

Today’s Meaning:

General Description:
This talisman was a great favorite in olden times, and was composed of the Seven Vowels of the Greek Alphabet. The desired favours were supposed to be granted upon the correct utterance of the forty-nine different sounds of the Seven Vowels, each vowel having seven distinct methods of expression. Of the many benefits supposed to be conferred were – good health, happiness, wisdom, fortune, foresight, success in all undertakings, complete protection from moral, as well as physical ills, and control over the powers of darkness. The ancients thought that there was an affinity between the seven vowels and the seven planets which they believed kept this earth in existence.
