If Andromeda Galaxy were brighter, this is what we’d see

Andromeda Galaxy is the farthest object in the sky that we can see with the naked eye. But if you don’t know where to look, you won’t notice it. But if it were much more brighter, its appearance in the sky would be sensational. The moon is a good reference about what we’d see in the image below:

The Size Of Earth Compared to Other Planets and Stars (and the Universe)

When it comes to big numbers, very big numbers, human brain is weak. In fact, our brains cannot deal with the really large numbers. That’s why when the subject is Earth, planets, Solar System, galaxies, and in general, the Universe, we cannot truly conceptualize the things. A lot of people think we’re “conquering” the space (we are far, far away from that – and maybe we never will), or the “aliens” are regularly visiting Earth, as if it is just an hour’s drive from there. In fact, these people don’t truly understand what are they talking about, how big is the universe, how far the stars are, and how the Earth is a tiny, tiny spot in a vast space we are still striving to understand.

Here is a video published by the American Museum of Natural History showing the World’s population through time.

Top 15 Largest Living Bird Species

Birds form one of six basic animal groups, with the others being amphibians, fish, invertebrates, mammals and reptiles. They are endothermic vertebrates, characterized by feathers, toothless beaked jaws, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. They reproduce by laying of hard-shelled eggs (eggs fertilize inside the female). The fossil record indicates that birds are the last surviving group of dinosaurs. So, they are also termed avian dinosaurs.

Birds (Aves) range in size and weight from the 5 cm (2 in) and 1.6-2 grams bee hummingbird to the 2.75 m (9 ft) and 104-156 kg (229-344 lbs) ostrich. Here are the top 15 largest (by body weight) living bird species.
