Planet Survives in Hell - Scientists Make a New Discovery

Scientists have discovered a gas giant, HD 156295 b, orbiting a hot A-type star. The planet is located in the habitable zone, receiving about 60% of the radiation Earth gets from the Sun, and could become the first known exoplanet in such a zone around a star of this type.

Astronomers have reported the discovery of a gas giant, HD 156295 b, orbiting an A-type star—the hottest known star with a planet found in its habitable zone. The star is visible to the naked eye, about nine times brighter than the Sun, heated to 7500 °C, and located 140 light-years from Earth. The planet is estimated to be nine times heavier than Jupiter, located about 4 astronomical units from the star, and completes an orbit every 2200 days. It receives about 60% of the radiation Earth gets from the Sun. If confirmed, HD 156295 b would become the first known exoplanet in the habitable zone of an A-type star. The discovery was made using the 'pulsation timing' method. The article also mentions a previously discovered rocky exoplanet, Gliese 3378b, and draws a parallel with the possible loss of Mars' atmosphere.
