A thoughtform is a manifestation of mental energy, also known as a tulpa in Tibetan mysticism. Its concept is related to the Western philosophy and practice of magic.  Mantras, the Sanskrit syllables inscribed on yantras, are essentially “thought forms” representing divinities or cosmic powers, which exert their influence by means of sound-vibrations.

Ophiuchus is a large constellation located around the celestial equator. Its name is from the Greek Ὀφιοῦχος “serpent-bearer”, and it is commonly represented as a man grasping the snake that is represented by the constellation Serpens. Ophiuchus was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations. It was formerly referred to as Serpentarius.

Coronal mass ejection

In science & nature on January 3, 2011 at 9:54 pm

A coronal mass ejection (CME) is a massive burst of solar wind, other light isotope plasma, and magnetic fields rising above the solar corona or being released into space.

Coronal mass ejections are often associated with other forms of solar activity, most notably solar flares, but a causal relationship has not been established. Most ejections originate from active regions on the Sun’s surface, such as groupings of sunspots associated with frequent flares. CMEs occur during both the solar maxima and the solar minima of sun activity

In general, super-Earths are defined exclusively by their mass, and the term does not imply temperatures, compositions, orbital properties, or environments similar to Earth’s. A variety of specific mass values are cited in definitions of super-Earths. While sources generally agree on an upper bound of 10 Earth masses (~69% the mass of the smallest Solar System gas giant Uranus), the lower bound varies from 1 or 1.9 to 5  with various other definitions appearing in the popular media.  Some authors further suggest that the term be limited to planets without a significant atmosphere.
