It’s the month of Halloween and we’re all getting ready to scare each other because as Brackett from the Halloween series rightly said, “It’s Halloween; everyone has a right to one good scare.” However, NASA has taken it to an extraordinary level. In a series of tweets from the NASA Exoplanets account, as well as a website dedicated to the topic, the US space agency decided to scare people with the terrifying properties of exoplanets.
“Tis the scary season and time to celebrate exoplanets where every day is Halloween!” Nasa Exoplanets tweeted. A planet outside our solar system that orbits another star is known as an exoplanet. The galaxy has more planets than stars, as NASA’s Kepler Space Telescope has shown.
Spooky galaxy
The Twitter handle describes “HD 209458 b”, a gas giant discovered in 1999 as a space skeleton. It also symbolizes a planet with a monster that has flesh ripped from its bones. The gas giant exoplanet HD 209458 b orbits an F-type star. It has a mass of 0.73 Jupiters, completes one orbit around its star in 3.5 days, and is 0.04707 AU away. Sharing an infrared image from NASA’s Spitzer that looks like a snake, the agency tweeted: “The coiled object is actually the core of a dense, dirty cloud large enough to swallow dozens of solar systems.
The Spitzer Space Telescope was the last mission in NASA’s Great Observatories program. It detected infrared radiation, primarily thermal radiation. NASA also showed the ‘home of Frankenstein’s monster’, a planet with a Neptune-like sky. “Lightning strikes against the HAT-P-11b sky vortex and charges any monster that needs it,” he tweeted. The Neptune-like exoplanet HAT-P-11 b orbits a K-type star. It has a mass of 26.69772 Earths, completes one orbit around its star in 4.9 days, and is 0.05254 AU away. Its discovery was announced in 2008.
Winds on HD 189733 b can reach 5,400 mph (2 km/s). On this exoplanet, getting caught in the rain would cause death by various wounds, the tweet said. To the human eye, this distant planet appears bright blue. But according to NASA, any space traveler who mistakes it for Earth’s friendly skies would be sorely mistaken, as it comes from a hazy atmosphere that contains high clouds laced with silicate particles.
