Why can't we see stars in space?
When viewing images from spaceships or the International Space Station capturing sunlit objects like Earth or the Moon, there’s a noticeable absence of the dazzling nighttime sky full of stars that we might expect. Unlike the magical scenery we witness on Earth, space often appears empty and lacking in stars due to various factors. Unlike our familiar blue sky caused by sunlight scattering in our atmosphere, the lack of atmosphere in space causes the sky to always appear black. This is because there’s no medium to scatter the light and create a blue appearance. However, despite the darkness, if you were on the space station, you’d still experience significant sunlight, similar to a cloudless day on Earth. This brightness affects photography too, where short exposure settings are used to capture sunlit objects but result in a lack of visible stars. Contrary to Earth’s beautiful blue-to-orange-red sky at dusk and dawn, watching a sunset on Mars would yield an orange-brown daytime sky that gains a bluish tint during sunset. The reason behind this difference lies in the Martian atmosphere, which contains larger dust particles causing a phenomenon called “Rayleigh scattering.” This scatters blue light, giving the Martian sky its unique appearance. As for the absence of rings around Earth, unlike gas giants, rocky planets like Earth likely did not experience the conditions necessary for ring formation. While theories suggest Earth may have had a ring system in the past due to a collision, this debris possibly contributed to the formation of our Moon. The existence of a mysterious ”Planet Nine” on the fringes of our solar system, believed to be larger and more massive than Earth, remains a debated topic. Water, once considered scarce in space, has been discovered in various forms across our solar system, including on asteroids, comets, the Moon, and Mars. Mars, in particular, has water at its poles hidden beneath ice and dust, while Jupiter’s moon Europa harbors a potentially vast ocean of liquid water beneath its icy surface. Surprisingly, Neptune, despite its distance from the Sun, emits more heat and displays more atmospheric activity than expected.

Steroids and Sports. Content Warning.
One of the most widely discussed and controversial arenas of human performance concerns the use of steroid supplements to enhance athletic ability for a variety of sports, ranging from bicycling to baseball. There is strong evidence that human athletes have attempted to enhance their athletic performance using steroids since the 1950s, but whether, and in which sports, steroids are actually effective remains controversial (reviewed by Ryan 1981; George 2003; Hartgens and Kuipers 2004). In general, steroids used by athletes encompass a wide variety of forms of the androgen testosterone (George 2003), and most seem to have the classical androgenic and anabolic effects on men, although steroid use by women cannot be ignored (Malarkey et al. 1991; Gruber and Pope 2000). Alternative forms of testosterone (e.g., testosterone enanthate, methandrostenolone) are typically used by those desiring enhanced performance because ingested or injected testosterone is quickly metabolized into inactive forms (Wilson 1988). Therefore, the human studies we cite relate to testosterone derivatives. However, early studies on the effects of steroids on human performance had major design flaws: B. Absence of control group and double-blind study, presence of confounding factors (such as differences in training level and motivation). and inadequate statistical methods (Bhasin et al. 2001; reviewed by George 2003). Due to these issues, the question of whether and how steroids actually improve athletic performance has been debated for many years until more recent research has conclusively demonstrated the significant effects of steroids. remained unresolved.
