A group of astronomers from the University of Kansas processed data from NASA space satellites. For the first time, the TESS and Spitzer telescopes were able to display the atmosphere of one of the most unusual exoplanets, it is named Hot Neptune. Having opened it, the scientists named it LTT 9779b, giving it the first spectral characteristic of a planet thats spectrum differs from many previously studied large planets.
Ian Crossfield, associate professor of physics and astronomy at California State University, noted that the planet is extremely irradiated by its star, and its temperature is over three thousand degrees Fahrenheit.
It could be the reason that the planet's atmosphere could completely evaporate. However, the observations made by the Spitzer satellite show the atmosphere in infrared light. And although the atmosphere actually exists, the astronomers concluded that it is unlikely that a person will like the conditions on it. The first to measure was the light that comes from a planet that actually shouldn't be. It actively emits a glow in infrared light.
The second thing that the scientists were able to find out: the planet's surface is actually molten and may contain lead, platinum, chromium, stainless steel in its atmosphere. One year on that amazing planet lasts only 24 hours.
It is at this speed that it revolves around its star. It is quite extreme. Hot Neptune has recently become fully characterized, and this planet was one of the first Neptune-sized to be discovered during the NSAS space mission to find habitable planets.
The astronomers explained that the factors showing the possibility of habitat on exoplanets were based on measurements of infrared light while rotating 360 degrees around its axis. Infrared light shows the temperature level, and the areas where the hottest and coldest zones are. The planet turned out to be much colder than the scientists expected.
It is due to the fact that it reflects most of the starlight falling on it, presumably due to daytime clouds. The results were called the first step towards a new stage in exoplanet research.
