Enaiposha, a new planet, is not like any other planet in our solar system.
It began as just another exoplanet in the "ordinary" group. Nobody anticipated that a world that was previously believed to be a miniature
Neptune would exhibit characteristics of a super-Venus and alter
our perception of particular planetary types.
The peculiar location of Enaiposha, which circles a red dwarf star approximately
47 light-years from the Sun, was further explored by astronomers using JWST data.
An unexpected "super-Venus"
The identification GJ 1214 b, which also refers to Enaiposha, was first assigned
to a category that typically characterizes tiny, gas-rich worlds. But according to recent findings, it resembles Venus more, but on a larger scale.
Because it seems to have a thick atmosphere made up of hydrogen, helium, water,
methane, and carbon dioxide, scientists suggest referring to it as a super-venus.
Recent tests that revealed minute traces of molecules at important spectrum locations
led to this discovery.
Why Enaiposha deviates from the norm
Although they are not found in the solar system, sub-Neptune planets—planets
smaller than Neptune—are the most prevalent kind of planets in the Milky Way.
Various gases make up their atmospheres, and atmospheric spectroscopy is used
to determine which gases are present.
In contrast to a normal sub-neptune,
Enaiposha has haze and aerosols covering its higher layers.
Because of this, spectroscopic analysis of the atmosphere to determine which
gases make up the atmosphere on the exoplanet is extremely challenging.
Although most views of Venus's surface are obscured by clouds, Enaiposha goes
beyond this. It is particularly challenging to investigate since it is larger, hotter, and covered
in layers.
A light-diluting atmosphere
Tiny dips appeared on the spectrograph where specific gasses absorb starlight
when Enaiposha passed between its star and Earth.
A metal-rich atmosphere with less hydrogen
floating around than scientists had anticipated was suggested by the findings.
Although the team's investigation indicated the presence of water vapor in the
atmosphere, that was not the main story.
Strangely for a planet that was previously classified in a more straightforward manner,
tiny indications of complicated metals surfaced.
Additionally, specific light wavelengths that revealed the traces of carbon dioxide
and methane were absorbed as starlight moved through Enaiposha's outer layers,
or atmosphere.
There might be CO2 on Enaiposha.
Astronomers Kazumasa Ohno of the National Astronomical Observatory of Japan
(NAOJ) and Everett Schlawin of the University of Arizona led the investigation.
A subtle hint that carbon dioxide might be present in amounts similar to those on
Venus was given to the scientists. They witnessed the transformation of light as it passed through the dense clouds
of Enaiposha.
The potential applicability of these techniques to areas that may support life is
one positive feature. Because of its intense heat, Enaiposha is not a promising place to live.
However, by examining its hazes and dense clouds, scientists may be able to better
understand the atmospheres of other exoplanets in less harsh environments. For anyone looking to find breathing air outside of our own system, it is important.
Enaiposha and further research
As a super-Venus, some are interested in determining whether
the metals in Enaiposha's air may create intricate clouds or droplets. Perhaps it explains why its atmosphere allows so little light to penetrate through.
Others believe it might serve as a precursor to modeling the evolution of thick
atmospheres. It may also demonstrate how sub-Neptunes can change over time.
The formation and evolution of sub-Neptunes like GJ 1214 b
will be better understood in the future thanks to additional modeling
of the planet's atmosphere, inner structure, and origins.
