Life on hot Jupiters

Information about Hot Jupiters• Hot Jupiters are a class of extra

solar planets whose mass is close to or exceeds that of Jupiter (1.9 × 1027 kg), but unlike in our own solar system the planets referred to as Hot Jupiters orbit within approximately 0.05 AU of their parent stars. In comparison, a Hot Jupiter is about eight times closer to its star than Mercury is to the Sun.

Information about Hot Jupiters• Hot Jupiters have some commo

n characteristics:• They have a much greater chan

ce of transiting their star as seen from Earth than planets of the same mass in larger orbits.

• They are all thought to have migrated to their present positions because there would not have been enough material so close to the star for a planet of that mass to have formed in situ.

What is life?

• What is life? Does this sound like a strange question to you? Of course we all know what is meant by the word "life", but how would you define it?

• Even the biologists have a tough time describing what life is! But after many years of studying living things biologists have determined that all living things do share some things in common:

1) Living things need to take in energy 2) Living things get rid of waste3) Living things grow and develop4) Living things respond to their environment5) Living things reproduce and pass their traits onto their offspring6) Over time, living things evolve (change slowly) in response to their environment

Suitable Life on hot Jupiters

• "Water's at the top of the shopping list of ingredients for life," says Hugh Jones of Liverpool John Moores University .

• Spitzer, a space-based infrared telescope, obtained the detailed data, called spectra, for two different gas exoplanets. Called HD 209458b and HD 189733b, these so-called "hot Jupiters" are, like Jupiter, made of gas, but orbit much closer to their suns.

• The data indicate the two planets are drier and cloudier than predicted. Theorists thought hot Jupiters would have lots of water in their atmospheres, but surprisingly none was found around HD 209458b and HD 189733b. According to astronomers, the water might be present but buried under a thick blanket of high, waterless clouds.

• Therefore it is possible for Hot Jupiters to have life. These life maybe look like jellyfish, cuttlefish or some balloon object.

• Or even water life can be present.

How the Life live in the hot Jupiters

It is used to flow on the cloud or swim in the water. Provide a large surface area to adsorb heat.

Some root like tentacle — For catching food and holding companion with each other.

• Perhaps these life can flow on the cloud or swim in the water freely and happily, they can live using the heat released by the star nearby as food or energy. They use the water vapor as raw material for growth and replicate themselves easily and randomly by movement of star.

How the Life live in the hot Jupiters

• Life in hot jupiters can make use of the nuclear power, thermal energy or sun light to survive. They make use of these energy to move.

Conclusion• Until now, the only planets for which spectra were

available belonged in our own solar system. The planets in the Spitzer studies orbit stars that are so far away, they are too faint to be seen with the naked eye. That means both planets are at least about a million times farther away from us than Jupiter. In the future, astronomers hope to have spectra for smaller, rocky planets beyond our solar system. This would allow them to look for the footprints of life -- molecules key to the existence of life, such as oxygen and possibly even chlorophyll.
