Welcome to the KELT-9 system. The host star is a hot, fast-spinning, Type A star that is about 2.5 times more massive and almost twice as hot as our sun. The hot star blows up its nearby planet KELT-9b with huge amounts of radiation, leading to a daily temperature of 7800 degrees Fahrenheit, hotter than most stars and only 2000 degrees cooler than the sun.

The LHS 1140b is located in the habitable liquid water area surrounding its hospitable star, a small, pale red star called LHS 1140. The planet weighs about 6.6 times the size of the Earth's mass and is shown passing in front of LHS 1140. The blue depicts the atmosphere that the planet may have preserved.

Conceptual image of the artist on the surface of the exoplanet TRAPPIST-1f. Of the seven exoplanets discovered around the orbit of the TRAPPIST-1 dwarf star, this is perhaps the most suitable for life. It is similar in size to Earth, slightly cooler than Earth's temperature, and is in the habitable zone of the star, which means that liquid water (and even oceans) can be on the surface. The proximity of the star gives the sky a touch of salmon, and the other planets are so close that they appear in the sky, much like our own moon.
