WASP-104 b
WASP-104 b Encyclopedic Information
WASP-104 b is not just another gas giant; it is a cosmic anomaly that challenges our understanding of planetary darkness. Often dubbed one of the darkest planets ever discovered, this hot Jupiter reflects so little light that it is effectively invisible to the naked eye, appearing as a void in the fabric of space. Located roughly 466 light-years away in the constellation Leo, it serves as a fascinating study in extreme planetary physics, where the proximity to its host star creates a hellish, light-absorbing environment that defies conventional astronomical expectations.

History & Significance
Discovered in 2014 by the Wide Angle Search for Planets (WASP) consortium, WASP-104 b was identified using the transit method, where scientists observed the periodic dimming of its host star as the planet crossed its face. While it lacks a mythological namesake, its dark nature has earned it comparisons to the primordial void of chaos found in various creation myths. The discovery was made possible by ground-based robotic telescopes that continuously monitor thousands of stars, proving that even with terrestrial equipment, we can uncover the most mysterious corners of our galaxy.
Following its initial identification, the planet became a focal point for researchers using the Kepler Space Telescope. By analyzing the light curves of the system, astronomers were able to calculate its remarkably low albedo. Unlike the reflective clouds of Jupiter, WASP-104 b absorbs nearly 99% of the starlight that hits it, making it darker than coal or even fresh asphalt. This revelation transformed the planet from a standard exoplanet candidate into a celebrity of the astrophysics community, highlighting the incredible diversity of atmospheres existing in the deep cosmos.
Physical Structure
WASP-104 b is a bloated gas giant, likely composed of hydrogen and helium, but its atmosphere is anything but standard. Because the planet is locked in a tight orbit—completing a full year in just 1.76 days—it is subjected to intense tidal forces and scorching temperatures. This extreme proximity causes the planet to be tidally locked, meaning one side perpetually faces its star while the other remains in eternal shadow. The intense heat prevents the formation of reflective clouds, which would normally bounce light back into space; instead, the atmosphere is likely filled with alkali metals like sodium and potassium that act as a light-trapping sponge.
Beneath its outer gaseous layers, the planet’s internal structure remains a subject of intense theoretical modeling. It is believed that the intense radiation from its host star has bloated the planets radius, giving it a lower density than one might expect for a body of its mass. The magnetic field, likely generated by a metallic hydrogen mantle deep within the interior, interacts with the stellar wind to create a turbulent, high-energy environment. This is a world of perpetual twilight and absolute absorption, where the chemistry of the upper atmosphere creates a soot-like shroud that ensures almost no light escapes once it enters the planets grasp.
