Best Planet Climate Map of Space

According to the best space climate map ever created, an enormously hot planet, 260 light-years from Earth, shows signs of water vapor in its atmosphere despite the burning heat that will melt iron. In our article, we briefly talk about this planet.
According to the best space climate map ever created, an enormously hot planet, 260 light-years from Earth, shows signs of water vapor in its atmosphere despite the burning heat that will melt iron.

Called WASP-43b, the Jupiter-sized planet is so hot that the temperature reaches 1648 degrees during the day. At night it is a bit colder (about 537 degrees) but still hot enough to melt silver.

Jean-Michel Desert from Colorado Boulder University, one of the co-authors of the study, states in the statement: “The WASP-43b is strange in many ways. It is Jupiter in size, but its mass is twice the mass of Jupiter. Its orbit around the star, called the orange dwarf, takes about 19 hours. This means blinking the Earth compared to the 365 days it travels around the Sun. ”

Scientists have used the Hubble Space Telescope to create the global temperature map of WASP-43b and say it is the best map ever recorded. This map shows altitude-dependent temperature variations, and they report that it will someday be useful in vehicles to search for water vapor and other vital traces on small Earth-sized planets.

“The picture that emerges when accurate measurements of the thermal structure and chemical entities in the atmosphere are made helps to make comparative studies between planets outside the solar system.” adds Jacob Bean from the University of Chicago.


Wasp-43b is the planet of extremes. Its orbit is so close to the star that it takes only 0.8 earth days to turn around the star. Researchers say the winds on this planet are faster than sound.

How this planet gets so close to its star is a mystery. According to the amount of water in his atmosphere, this planet formed in the orbital radius of Jupiter, then slid inward.
“These observations allow us to identify the abundance of water in the atmosphere that plays an important role in planet formation.” "By measuring the composition of the planet, it will give a better idea of ​​where this planet formed in the pre-planet cloud of the star," says Desert.

"The gravitational effect of a star or planet passing nearby may have brought this planet closer to the star it orbits." says Bean.

The proximity of the planet to its star, which is 70% of the sun, indicates that this planet is tidally locked. This means that the gravity of the star causes one face of the planet to remain facing the star for quite some time. Also, the star's massive gravitational force circularized the orbit of the planet over time.

WASP-43b and SU

In November 2013, the team conducted a 3-day observation with the Hubble Space Telescope, monitoring at least 3 "planet days" of the planet's rotation. (Between each spin of the planet, Hubble adds that 6 hours of deactivation for other projects before returning to observe WASP-43b.)

While this planet offers a variety of mysteries to post-solar researchers, the promising point is; Compared to the models of creating hot Jupiters, how high the planetary atmosphere is similar to the composition of the main star.

Stars and planets are formed by absorbing many gases from the same gas and dust nebula. The atmosphere of the WASP-43b is warm, but the water vapor abundance of the WASP-43b is similar to the star's hydrogen and oxygen abundance.

"What we're interested in is that water is getting abundant or running down," explains Bean and Jupiter, explaining that a non-solar system planet is expected to have a high percentage of helium and non-hydrogen element elements or metals.
Larger planets have less metal diversity than the star they turn around. This is exactly what is observed in WASP 43-b.
