Need Help in writing a Research proposal

Sun Aug 19, 2012 6:31 am by The Students Forum(TSF)

How Do You Write a Research Proposal for Academic Writing
If you are in college then one of the many questions on your mind may be, how do you write a research proposal for academic writing. To write an academic research proposal is most likened to writing a proposal that addresses a project. The only difference is that the research proposal has either academic or scientific research at the …

Astronomers using the 3.6-meter telescope at the European
Southern Observatory's (ESO) La Silla Observatory, in Chile, announce
the discovery of a new super-Earth-class extrasolar planet, which may be
able to support life as we know it.

According to measurements produced by the High Accuracy Radial Velocity
Planet Searcher (HARPS) spectrograph on the telescope, the planets lies
exactly at the edge of its parent star's habitable zone.

A super-Earth is an exoplanet that is larger and heavier than Earth, but
only to a limited extent. They are nowhere near as large as a gas
giant, meaning they are way smaller than Jupiter or Saturn.

This particular planet is called Gliese 163c, since it is the
second planet from its parent star. Experts believe that temperatures on
this world may allow for the existence of liquid water on its surface.

Though there is no way of knowing this with absolute certainty, all data
available to date seem to point to this conclusion. “There are a wide
range of structures and compositions that allow Gliese 163c to be a
habitable planet,” explains Xavier Bonfils.

The expert holds an appointment with the Joseph Fourier
University-Grenoble, in France. He made the statement in an email sent
to Space.
He adds that there are certain scenarios in which Gliese 163c is not a
habitable planet. Therefore, more studies are needed before we can say
anything for sure.

Bonfils says that he and his team made the discovery during a survey of
more than 400 red dwarf stars. Gliese 163 was found around 50
light-years from Earth. Closer examinations revealed the existence of
two exoplanets in its orbits. A third one was also hinted at, but not
thoroughly confirmed.

HARPS data indicate that Gliese 163c is about 7 times the mass of Earth.
This leaves researchers with only two possible options when it comes to
determining the world's composition – it could either be a large rocky
planet, like Earth, or a very small gas giant.

“We do not know for sure that it is a terrestrial planet. Planets of
that mass regime can be terrestrial, ocean, or Neptune-like planets,”
Bonfils went on to say. One thing that is important to know about this
world is that it needs just 26 days to complete a full orbit around its

This means that it’s much closer to the star than Mercury is to the Sun
for example. Granted, a red dwarf is not as hot as a yellow dwarf, but
the short distance could mean that temperatures on the exoplanet are
very high.
