An
exoplanet, or
extrasolar planet, is a
planet beyond our
solar system, orbiting a
star
other than our
Sun.
Extrasolar planets became a subject of scientific
investigation in the mid-19th century. Many
astronomers supposed that such planets existed, but they
had no way of knowing how common they were or how similar
they might be to the planets of our solar system. The discovery of
extrasolar planets
sharpens the question of whether some might support
extraterrestrial life......Extraterrestrial
life is defined as life which does not originate from planet Earth. The
existence of life outside the planet is theoretical and all assertions
of such life remain disputed.
Over 400 exoplanets have been
identified as of late 2009, and more are continually being discovered.
Dr.
Alan Boss
of the
Carnegie Institution of Science
estimates there may be a “hundred billion” terrestrial planets in our
Milky Way Galaxy
alone. Dr Boss believes many could have simple life forms and there could
be thousands of civilizations in our galaxy. Dr. Boss guesses that each
sun-like star has on average one Earth-like planet.
....Recent work at Edinburgh University tried to quantify
how many intelligent civilizations might be out there. The research
suggested there could be thousands of them.....

PVAF is publishing today's news story about the continuing discovery
of exoplanets....because this is the type of life science knowledge that
is contained in the entire corpus of the extant texts of
vED in
sNskRUt language...vED
states
in all texts of the existence of infinite number of universes with
infinite diversity from each other...The texts of
18 puraaAN repeatedly
states that our own universe has 218 domains of existences...each
one with different nature of time, space and life characteristics...and
the domain where we humans exists is made of 7
Dv`ip
(land masses) surrounded by liquid masses of different liquids - and
each of them of dimensions which makes our planet earth/solar system
look like a tiny spec in space......
vED has all the sciences of life and creations that
the current humanity understands and has yet to understand in the
continually new frontiers of all currently known sciences.... including
the what Einstein has left for us and some of which we still cannot
understand.... and/or quantum physics scientists of mid-twentieth
century such as Paul
Direk who has made us aware that the world we perceive and see is
not the same world we exist in - the world we exist in is in true reality
multiple dimensions of existence and each dimension of natural
properties of infinite diversity than that of ours...(read

Newly found 'exoplanets'
are out of this world
Washington Post:
Tuesday, October 20, 2009: By Joel Achenbach
|
Astronomers are finding planets by the dozen.
European astronomers
announced Monday that they had found 32 new "exoplanets" orbiting
distant stars.
That brings to about 400 the number of planets found since the
breakthrough discovery in 1995 of the first planet outside our solar
system. Most have been quite large, many times the size of Jupiter.
This
latest batch, however, includes modest-sized worlds that are in the
category known as "super Earths." The smallest of the bunch has the mass
of about five Earths.
The planets cannot be seen directly because of the glare of the parent
star. Astronomers detect them by studying variations in starlight.
In
this latest study, astronomers from the European Southern Observatory
scrutinized about 2,000 relatively nearby stars over five years. They
used a telescope in La Silla, Chile, equipped with an instrument known
as the High Accuracy Radial Velocity Planet Searcher (HARPS). The
instrument measured the slight wobble in starlight caused by the
gravitational disturbance from a planet.
The 32 new planets were found around a variety of stars. Some stars were
circled by multiple planets.
|
The European team thinks the findings
indicate that planets are common in our galaxy.
Planets were found, for
example, in orbit around "metal-poor" stars -- those lacking elements
other than hydrogen and helium -- which until now had been considered
unlikely places for planets to form.
Astronomers hope someday to find signs of a rocky, Earth-mass planet in
an Earth-like orbit -- moving around the star in the "habitable zone"
where water could, in theory, be liquid at the planet's surface.
But
such hypothetical planets would have such a slight perturbation on
starlight that they are difficult to detect with current instruments.
Astronomer Stéphane Udry of Geneva University said by e-mail that a new
instrument under development, known as ESPRESSO (Echelle Spectrograph
for Rocky Exoplanet- and Stable Spectroscopic Observations), "should
allow us to detect Earth twins around solar-type stars, within 5 to 10
years."
"Personally, I am convinced that planets are everywhere," Udry said.
"Nature does not like void." |

An
exoplanet, or
extrasolar planet, is a
planet beyond our
solar system, orbiting a
star
other than our
Sun.
As of 19 October 2009 (2009
-10-19), 403 exoplanets are listed in the
Extrasolar Planets Encyclopaedia. The vast majority have
been detected through
radial velocity observations and other indirect methods
rather than actual imaging.
Most announced exoplanets are
massive
gas giant planets thought to resemble
Jupiter, but this is a selection effect (bias) due to
limitations in detection technology.
Projections based on recent
detections of much smaller worlds suggest that lightweight,
rocky planets will eventually be found to outnumber extrasolar
gas giants.
Extrasolar planets became a subject of scientific
investigation in the mid-19th century. Many
astronomers supposed that such planets existed, but they
had no way of knowing how common they were or how similar
they might be to the planets of our solar system.
|
The first confirmed radial velocity
detection was made in 1995, revealing a gas giant planet in a
four-day orbit around the nearby
G-type star
51 Pegasi.
The frequency of detections has
tended to increase on an annual basis since then. It is
estimated that at least 10% of sun-like stars have planets, and
the true proportion may be much higher.
The discovery of extrasolar planets
sharpens the question of whether some might support
extraterrestrial life.
Currently
Gliese 581 d, the fourth planet of the
red dwarf star
Gliese 581 (approximately 20
light years from
Earth),
appears to be the best example yet discovered of a possible
terrestrial exoplanet that orbits within the
habitable zone surrounding its star.
Although initial measurements
suggested that Gliese 581 d resided outside the so-called "Goldilocks
Zone", additional measurements place it firmly within......

EXOPLANETS WITH POTENTIAL FOR EXTRA-TERRESTRIAL LIFE.....

........WHAT IS EXTRATERRESTRIAL
LIFE???!!!!.... |
Extraterrestrial life is
defined as
life
which does not originate from
planet
Earth.
The existence of life outside the planet is theoretical and all
assertions of such life remain disputed.
Hypotheses regarding the origin(s)
of extraterrestrial life, if it exists, are as follows: one proposes
that it may have emerged, independently, from different places in the
universe. An alternative hypothesis is
panspermia
or
exogenesis,
which holds that life emerges from one location, then spreads between
habitable planets.
These two hypotheses are not
mutually exclusive.
The study and theorization of extraterrestrial life is known as
astrobiology,
exobiology or xenobiology. Speculated forms of extraterrestrial life
range from life with the simplicity of
bacteria
to
sapient
or
sentient
beings.
Suggested locations which might
have once developed, or presently continue to host life similar to our
own, include the planets
Venus
and
Mars,
moons of
Jupiter
and
Saturn
(e.g.
Europa,
Enceladus
and
Titan)
and
Gliese 581 c
and
d,
recently discovered to be near Earth-mass
extrasolar planets
apparently located in their star's
habitable zone,
and with the potential to have liquid water.
To date, no credible evidence of
extraterrestrial life has been discovered which has been generally
accepted by the mainstream scientific community.
All other proposals, including
beliefs that some
UFOs
are of extraterrestrial origin (see
extraterrestrial hypothesis)
and claims of
alien abduction,
are considered hypothetical by most scientists.
UFO
sightings are sightings of unidentified flying objects that may or may
not be connected with extraterrestrial intelligent life. Most of these
sightings can be dismissed as sightings of Earth based aircraft or known
astronomical objects
or perpetration of
hoaxes.
However some sightings have gone unexplained, having been reported in
some cases by police and airline pilots.
In 2006,
New Scientist
published a list of ten controversial pieces of evidence that
extraterrestrial life exists,[4]
but scientists do not consider them credible since no direct
observational evidence has been encountered. However, many scientists,
such as
Carl Sagan,
believe that it is nearly impossible that no other intelligent life
exists in the universe.
