THE UNIVERSAL TIMES MAGAZINE PRESENTS:
GLIESE 436b - THE NEPTUNE-SIZED EXTRA-SOLAR PLANET

In 2004, R. Paul Butler and Geoffrey Marcy discovered the Neptune-sized planet Gliese 436b (also known as GJ 436b), via the radial velocity method. Located in the Leo constellation, the Gliese 436b is one of the first planets with a small amount mass making it comparable to Neptune. Orbiting the star is Gliese 436, one orbit around the red dwarf star is approximately 2 days and 15.5 hours long at a distance of just 4.3 million kilometers at about 30 light years from Earth. The Gliese 436b has an extremely perplexing atmosphere that has an abundance of carbon monoxide but a surprisingly low quantity of methane. Professor Joseph Harrington of the University of Central Florida believes that a planet like Gliese 436b is doing the opposite of what should be happening because it has an atmospheric temperature of more or less 400 degrees Celsius. The Gliese 436b is supposed to have major amounts of methane and no carbon monoxide. So, why is this happening? There are many different theories; however it is still quite a mystery to scientists. More recently, in 2008 a team of astronomers from the Spanish Research Council, including Dr. Jean Philippe Beaulieu have discovered a possible terrestrial-type planet orbiting a star in the...
