Astronomical Discovery

Astronomers at the W. M. Keck Observatory in Hawaii have made a jaw-dropping discovery: a distant exoplanet, known as WASP-69 b, boasting a fantastical tail that stretches an astonishing 350,000 miles into space! Situated 164 light-years away from Earth, this enigmatic planet bears an uncanny resemblance to a comet due to its unusual feature.

Characteristics of WASP-69 b

WASP-69 b belongs to the category of hot Jupiters—massive gas giants that orbit perilously close to their host stars. Shockingly, this planet completes a full orbit in fewer than four days and experiences scorching temperatures exceeding 600 degrees Celsius (about 1,112 degrees Fahrenheit).

The Tail Formation

The tail phenomenon arises from the intense radiation emitted by its nearby star, which bombards WASP-69 b's atmosphere, stripping away crucial gases such as hydrogen and helium. Coupled with powerful stellar winds, these escaping gases are drawn into a tail-like formation, extending more than 7.5 times the planet's radius. Just envision that: over 350,000 miles long—far surpassing the distance from Earth to the Moon!

Future Research and Implications

Researchers speculate that the length of the tail might even exceed current measurements; they lacked sufficient telescope observation time to capture its full extent. Interestingly, this tail might also vary in size depending on the intensity of the stellar winds—a phenomenon that could mean the tail shrinks if the winds diminish. Lead researcher Dakotah Tyler from the University of California, Los Angeles, stated, “If the stellar wind were to taper down, then you could imagine that the planet is still losing some of its atmosphere, but it just isn’t being shaped into the tail.”

Planetary Atmospheric Loss

Planetary atmospheric loss, a process not uncommon in astronomy, draws parallels to the fate of Mars, which lost a significant portion of its atmosphere over eons. What sets WASP-69 b apart, however, is its spectacular tail—a rarity in the cosmos. Despite the dramatic loss of gas—estimated at a staggering 200,000 tons per second—WASP-69 b's colossal size ensures that it won’t be completely stripped of its atmosphere anytime soon. Astronomers predict that this breathtaking tailed planet will remain an enigmatic fixture in our universe for thousands of years to come.
