Bad Astronomy Newsletter Welcome to the homepage for bad astronomy! as an astronomer, teacher, lecturer and all around science junkie, i am exposed to all sorts of people and their ideas about what goes on in the sky around them. New observations of a strange gas cloud show it’s inside our galaxy, not external to it.
Bad Astronomy Newsletter The andromeda galaxy and the milky way are the two biggest galaxies in what we call the local group, a collection of several dozen galaxies large and small all held together by their own gravity. Bad astronomy is all about astronomy, space, and science. science is the best tool humans have to understand the universe, and also? it's really cool. Inspired by the author's web site, "bad astronomy", the book attempts to explore twenty four common astronomical fallacies and explain the scientific consensus concerning these topics within the field of astronomy. At the moment 37 such dwarf satellite galaxies are known to orbit andromeda, and a priori you’d think they surround their host as well. but this is where things get really strange: in new research just published, astronomers found that nearly all of them are located between our two galaxies.

Gain a complete understanding of “bad astronomy” by philip c. plait from blinkist. the “bad astronomy” book summary will give you access to a synopsis of key ideas, a short story, and an audio summary. It is not surprising that this astronomer is quite skeptical about astrology, creationism, ufos, and velikovsky. he offers very good critiques of each of these topics, using scientific facts to undermine pseudoscientific claptrap. Since andromeda's halo is so faint, they couldn't see any light it emitted directly. instead, they did the opposite: they looked for light sources behind it, in this case quasars, active galaxies billions of light years away that are blasting out light. The andromeda galaxy, also called m31, is a huge spiral galaxy fairly close in size and mass to our own milky way. like the milky way it also has a central bulge of stars, and a supermassive black hole in its very core.
