There are many methods of detecting exoplanets. Transit photometry and Doppler spectroscopy have found the most, but these methods suffer from a clear observational bias favoring the detection of planets near the star; thus, 85% of the exoplanets detected are inside the tidal locking zone. In several cases, multiple planets have been observed around a star. About 1 in 5 Sun-like stars[a] have an “Earth-sized”[b] planet in the habitable zone. [c] Assuming there are 200 billion stars in the Milky Way,[d] it can be hypothesized that there are 11 billion potentially habitable Earth-sized planets in the Milky Way, rising to 40 billion if planets orbiting the numerous red dwarfs are included.
With the GRAIL data, the astronomers were able to map the gravity field both in and around over 1,200 craters on the lunar far side. This region--the lunar highlands--is our Moon's most heavily cratered, and therefore oldest, terrain. Heavily cratered surfaces are older than smoother surfaces that are bereft of craters. This is because smooth surfaces indicate that more recent resurfacing has occurred, erasing the older scars of impact craters. The Moon in the Birth Chart. The Moon is a very important planet in the Birth Chart as it is from this that we operate from through childhood and thus it becomes our foundation. Although we grow towards our Sun (our own 'mind') in adulthood, the Moon is a 'feeling, reflective' energy that picks up and stores early messages and experiences. Many of our behavioural and emotional problems can be uncovered by examining the role of Moon in the Natal Chart. The Moon informs and represents the way we habitually respond and react throughout life. It denotes our instinctive behaviour and the sign it is in describes its innate quality, whereas the house reflects the environmental influence. Any aspect to the Moon shows how it reacts. If for example it has a connection to Mars, then it may be more assertive in having its needs met. Moon with Venus will emphasise its female or creative quality and Moon in aspect to Mercury may be able to express its feeling in some communicative way.. A Lunar Eclipse is when our blue/green globe saunters between the trusty moon and glowing sun, our planet completely blocks the luminous rays of the sun but the moon remains visible.
