TOI-421B கிரகத்தில் தண்ணீரை கண்டுபிடித்த ஜேம்ஸ் வெப் தொலைநோக்கி! உயிர்கள் உள்ளதா?

The James Webb Space Telescope has made a groundbreaking discovery by detecting water vapor in the atmosphere of the exoplanet TOI-421b, a hot sub-Neptune located about 245 light-years from Earth. Unlike many similar planets, TOI-421b has a clear, haze-free atmosphere, allowing scientists to identify not only water vapor but also possible traces of carbon monoxide and sulfur dioxide. The planet’s atmosphere is dominated by lightweight hydrogen, which surprised researchers and suggests TOI-421b may have formed differently from other sub-Neptunes. This discovery provides valuable insights into the most common type of planet in our galaxy and helps astronomers better understand how these mysterious worlds evolve.
