Astronomers in Japan and Arizona, using data from the James Webb Space Telescope, have revealed a unique type of exoplanet as opposed to any solar system.
The exoplanet-defined as a planet that revolves around a star other than the sun-is called Enaiposha and is only 48 light years away, placing it in the immediate neighborhood of the solar system.
This also makes it close enough for astronomers to see if it has an atmosphere and what kind of. This is exactly what astronomers at the National Astronomical Observatory of Japan and the University of Arizona/Steward Observatory did – and found something unexpected.
‘Super Venus’
The latest data on ENAIPOSHA, also called GJ 1214 B and Gliese 1214 B, suggest that it has a rich in carbon-axide atmosphere, questioning previous perceptions of the synthesis of exoplanes of its size.
Although exoplanets tend to be classified as “hyper-earth” or “mini Neptune”, the atmosphere dominated by Enaiposha carbon dioxide makes it more likely to be a “super Venus”.
“The CO2 detected signal from the first study is tiny and thus requires careful statistical analysis to ensure it is real”, ” said Kazumasa ohno at the National Astronomical Observatory of Japan, Who Co-Led the Study.

Water World?
Enaiposha has been closely studied since its discovery in 2009, but until JWST arrived, astronomers could not see through the thick cloud blanket. This allows him to greatly reflect the light of his parent, making it cooler than expected.
Using the instrument of medium infrared radiation, JWST managed to reveal important new knowledge in its atmosphere. In May 2023, scientists at Oxford University She watched ENAIPOSHA, then described as “sub-course”, through a whole orbit of her star, with her changing heat observed as she went through phases, similar to how we see the Moon, Aphrodite and Hermes from Earth.
In addition to finding a large temperature difference between the day and the nightlife of the planet, scientists have discovered that the Enaiposha atmosphere is enriched with heavier molecules, such as methane and water.

Enaiposha is in the constellation of Ophihas (pronounced “or-fur), a huge summer constellation and one of the 13 that the sun travels every year. The other 12 are familiar with everyone as signs of the zodiac, so why isn’t Ophiuchus one of them?
Ancient Babylonians distributed the ecliptic-The phenomenal path of the sun through the sky – in twelve areas 30 ° and each one of the twelve constellations or “signs” that intersect it. Since 13 is an unlucky number, one fell. Ophiuchus began despite the sun spending for a long time in it since November 29th. 17 (usually regarded as Sagittarius despite the sun in this constellation from December 17 – January 20th.
I wish you clear skies and wide eyes.
