- Gamma Trianguli Australis (stars.astro.illinois.edu)
GAMMA TRA (Gamma Trianguli Australis). If this star were not so bright – within the top 150 stars – it would probably be ignored. But at mid-third magnitude (2.89), it just barely makes the list at number 149, and thus earns some measure of respect, which it deserves if for no other reason than that it anchors the southwest apex of bright and obvious Triangulum Australe (the Southern Triangle), which is dominated by mid-second magnitude Atria.
- How Animals See the World (artsandculture.google.com)
Each type of animal on Earth has evolved a range of senses and skills which allow it to live successfully in its environment. Many of these adaptations are very different from how humans have evolved, and compared to humans some of these adaptations feel like they belong in a superhero comic. Senses such as ultraviolet vision, extra color receptors, and echolocation are very hard for humans to imagine, yet are part of the everyday life of hundreds of species of animals.
