PIX4573447: Artist's view of a hot Jupiter HD 149026b - Exoplanet HD 149026b - Hot Jupiter - HD 149026b (in the background) is to date the hottest exoplanet in the universe. This warm Jupiter reaches a temperature of 2000 degrees; it absorbs almost all the light of its star and is therefore also the darkest planet in the universe. HD 149026b is located 256 years - light in the constellation Hercules. This artist's concept illustrates the hottest planet yet observed in the universe. This “” hot Jupiter”” called HD 149026b, is a sweltering 3,700 degrees Fahrenheit (2,040 degrees Celsius) - about 3 times hotter than the rocky surface of Venus, the hottest planet in our solar system. The planet is so hot that astronomers believe it is absorbing almost all of the heat from its star, and reflecting very little to no light. Objects that reflect no sunlight are black. Consequently, HD 149026b might be the blackest known planet in the universe, in addition to the hottest. HD 149026b is located 256 light - years away in the constellation Hercules. It is the smallest known transiting planet, with a size similar to Saturn's and a suspected dense core 70 to 90 times the mass of Earth. It speeds around its star every 2.9 days. Here, the planet is seen at night / Bridgeman Images

PIX4572752: Artist's view of an eruptive star - Flare star - Artwork: DG Canum Venaticorum (DG CVN) is a binary star located in the constellation Hunting Dogs. On 23 April 2014, a powerful gamma eruption from this system was recorded by the Swift satellite. DG Canum Venaticorum (DG CVN) is a binary star system in the northern constellation of Canes Venatici. On 2014 April 23, 2014, a gamma-ray superflare event was observed by the Swift satellite coming from the position of this system. It may have been perhaps the most luminous such events ever observed coming from a red dwarf star / Bridgeman Images
