With a black hole and two neutron stars, the Floawns EG-Y f781 system was discovered a few years ago already but it has only recently gained its moniker of Aurora Atra or “Black Dawn”. The reason for the recent increase in interest lies in a spectacularly close orbit of said black hole and one of its neutron star “brothers”. Their mean orbit puts them just 5 light seconds apart. More than 6 billion years ago the system was likely comprised of three extremely massive O-type or B-type stars which subsequently went supernova. In the distant future the system will again be ruptured when the black hole and neutron star finally merge and create new shockwaves of debris and radiation. Both stellar corpses cause a massive gravitational lensing effect in their embrace and to further add to the system’s awesomeness, this effect can be seen from the surface of a landable planet nearby. Aurora Atra indeed has a landable metal-rich iron-nickel planet (AB 1) orbiting the black hole at a mere 440 light seconds, slightly less than the distance of Earth from Sol. With a surface gravity over 1.5g and a blasting temperature of 1,200 Kelvin, landing and direct exposure to the neutron star’s immensely intense radiation should only be conducted under extreme “safety first” protection protocols. Even on AB 1’s tidally-locked “dark side” temperatures can be as high as 650 Kelvin. As mentioned before, explorers of AB 1’s surface can witness the black hole’s heavy gravitational lensing effects — with the neutron star “inside” — in the sky and against the bright backdrop of the Milky Way’s Norma Arm. AB 1 has one other peculiarity and it’s a planetary feature: From near orbit, visitors are able to see a particularly interesting giant rock formation which resembles a Human woman making an intricate gesture. There are a lot of creative metaphors describing the scenery but the most prominent one has earned the formation the nickname of “the Sorceress”. The Aurora Atra system also has a ringed type V gas giant. Due to its more complex chemical processes, this more uncommon class of gas giants is generally hot enough to have silicate vapour or even liquid iron “rain” in its upper atmospheres. It still lacks enough density and mass to have evolved into a brown dwarf but it’s nonetheless a testament to the star systems violent radiation onslaught. Most of the gas giant’s moons are landable and also geologically active. The most prominent moon (AB 3 a) has a slightly inclined orbit towards its parent gas giant so views are particularly rewarding here, even more so, because the moon has vast metallic magma fountains. As of 24th November 3308, most of the geological sites of the system haven't been thoroughly observed and still need further analysis. | → | With a black hole and two neutron stars, the Floawns EG-Y f781 system was discovered a few years ago already but it has only recently gained its moniker of Aurora Atra or “Black Dawn”.
