Just as there are
countless Buddha worlds
in the Buddhist cosmos,
so too are there
countless worlds in the cosmos
as space scientists know it.

Debunking Astrology
First of all, astrology is a pseudoscience. Secondly, astronomy is a science.
Astrology consists of belief systems used to explain the metaphorical influence of ten planets, 12 astrological signs, the moon and the sun on human relationships, using generalizations about people based on their date of birth.
It was invented out of ignorance about astronomy, because at that time, the science was being rediscovered in Europe.
Yet astrology has nothing to do with astronomy at all.
For astrology cannot account for the differences in personality of people born on the same day. Thus it lacks consistency.
Much of the similarities between people born in the same month are based on our ability to filter out the differences and focus on similar traits in behaviour due to cognitive bias.
Thus, astrology is an inadequate attempt to explain human relationships in a simple form.
All astronomy has shown us that the sun, the moon, the planets and the stars have no influence whatsoever on the behaviour of humanity.
If you wish to learn more about astronomy, human behaviour and relationships, then learn about astronomy, psychology and sociology.

Neutron stars have "mountains" and "starquakes"
Studying the 'mountains' and 'starquakes' that develop on neutron stars
(PhysOrg.com) -- Neutron stars have the potential to play an important role in understanding some of the mysteries of the universe. One of factors that could help lead to an understanding of gravitational waves and the mechanisms involved in giant flares in magnetars is the strength of the crust that forms on the outside of a neutron star. In an effort to better understand the neutron star crusts, Charles Horowitz, at Indiana University in Bloomington, and his colleague Kai Kadau, at Los Alamos National Laboratory in New Mexico, have used molecular dynamics to model neutron stars and come up with improved estimates of the breaking strain.

Caltech Scientist finds planet orbitting 3 suns
In the northern constellation Cygnus (The Swan) a planet the size of Jupiter orbits around three stars 149 light-years (1200 trillion kilometres) from Earth.
From the Caltech news release comes a challenge to the theories about planetary formations in complex solar systems.
Maciej Konacki reported this discovery in the May 2005 issue of Nature.
"If the parent star is orbited by a close stellar companion, then its gravitational pull can significantly truncate a protoplanetary disk around the main star. In the case of HD 188753, the two stellar companions would truncate the disk around the main star to a radius of only 1.3 astronomical units, leaving no space for a planet to form." - http://pr.caltech.edu/media/Press_Releases/PR12716.html
In the case of this triple star system, a red giant and an orange star orbit around a yellow star, according to SpaceFlight News http://www.spaceflightnews.com/forum/lofiversion/index.php/t1161.html.
"The new planet belongs to a common class of extrasolar planets called "hot Jupiters," which are gas giants that zip closely around their parent stars. In this case, the planet whips every 3.3 days around a star that is circled every 25.7 years by a pirouetting pair of stars locked in a 156-day orbit." - NASA Jet Propulsion Laboratory website http://planetquest.jpl.nasa.gov/
Regarding star system HD 188753, perhaps only large planetary masses can survive the combined tidal and solar forces of three stars in close orbit around each other.
My guess is that the planet, which is slightly larger than Jupiter, was too small to become a star.
Thus, in the formation of star systems, the larger masses become stars.
Any masses smaller than a certain size become planets. Judging from this example, the size limit may be slightly more than the size of Jupiter.
The size (diameter, surface area, volume and mass) of Jupiter is as follows:
Diameter: 108 × 1.43 m
Surface area: 1017 × 0.641 m2
Volume: 1025 × 1.52 m3
Density: 103 × 1.3 kg/m3 (1.3 g/cm3)
Mass: 1027 × 1.9 kg
Note: 10E8 = 100,000,000
cm = centimetre
m = metres
kg = kilograms
