"Rare Rainbow-Like 'Glory' Effect Detected on Chaotic Exoplanet"

Astronomers have potentially observed a rare "glory" phenomenon in the atmosphere of the distant exoplanet WASP-76 b, located 637 light-years away, making it a possible first outside our solar system. This planet, known for extreme conditions due to its close orbit to its star, exhibited a bright spot of light, possibly a "glory," on its eastern limb, suggesting diffractive atmospheric conditions. Further study is needed to confirm this discovery, but it could lead to new insights into atmospheric phenomena on other worlds and expand our understanding of distant galaxy atmospheric conditions.

"Unraveling the Mystery: Astronomers Investigate an Enigmatic Exoplanet's Fiery Nature"

Astronomers have studied the scorching exoplanet WASP-76 b using the MAROON-X instrument on the Gemini-North Telescope, identifying 11 chemical elements in its atmosphere. The findings suggest that the planet's composition reflects that of the protoplanetary disc from which it formed, and its extreme temperatures cause rock-forming elements to vaporize. The absence of certain elements requiring higher temperatures to vaporize suggests that WASP-76 b may have swallowed material from a Mercury-like planet. The study provides crucial insights into the formation and composition of giant planets.

Cannibal 'Hot Jupiter' planet devours Mercury-sized neighbor.

Astronomers have discovered that the ultra-hot Jupiter exoplanet, WASP-76 b, has a similar composition to its star, with the same abundances of elements heavier than hydrogen and helium. The team identified 11 chemical elements in the atmosphere of the planet, some of which haven't even been measured in the solar system gas giants Saturn and Jupiter yet. The planet's proximity to its parent star causes temperatures to soar to around 4,350 degrees Fahrenheit, hot enough to vaporize iron. The team also found a higher abundance of nickel than expected around WASP-76 b, which could imply that at some point in its history, the gas giant planet swallowed a smaller terrestrial world similar to Mercury that was rich with the element.

Exploring the Atmospheres of Extreme Exoplanets.

Astronomers have discovered that the ultra-hot exoplanet WASP-76 b has an atmosphere of vaporized rock, with temperatures soaring to around 4,350 degrees Fahrenheit. The team identified 11 chemical elements in the planet's atmosphere, some of which haven't even been measured in the solar system gas giants Saturn and Jupiter yet. The abundance of elements like manganese, chromium, magnesium, vanadium, barium, and calcium match closely with the quantities found in the sun, indicating that the composition of the planet is similar to the protoplanetary disk of material that collapsed to birth it. The team also discovered that certain elements in the atmosphere of WASP-76 b appeared to be "depleted," and the planet contains a chemical compound called vanadium oxide, which can have a big impact on hot giant planets.
