Cosmic latte

Cosmic latte
Cosmic Latte is a name assigned to the average color of the universe, given by a team of astronomers from Johns Hopkins University. Discovery of the color[edit] In 2001, Karl Glazebrook and Ivan Baldry determined that the color of the universe was a greenish white, but they soon corrected their analysis in a 2002 paper,[1] in which they reported that their survey of the color of all light in the universe added up to a slightly beigeish white. The survey included more than 200,000 galaxies, and measured the spectral range of the light from a large volume of the universe. The hexadecimal RGB value for Cosmic Latte is #FFF8E7. The finding of the "color of the universe" was not the focus of the study, which was examining spectral analysis of different galaxies to study star formation. Glazebrook's and Baldry's work was funded by the David and Lucile Packard Foundation. Naming of the color[edit] The color was displayed in a Washington Post article.

H II region An H II region is a large, low-density cloud of partially ionized gas in which star formation has recently taken place. The short-lived blue stars forged in these regions emit copious amounts of ultraviolet light that ionize the surrounding gas. H II regions—sometimes several hundred light-years across—are often associated with giant molecular clouds. The first known H II region was the Orion Nebula, which was discovered in 1610 by Nicolas-Claude Fabri de Peiresc. H II regions are named for the large amount of ionised atomic hydrogen they contain, referred to as H II, pronounced H-two by astronomers (an H I region being neutral atomic hydrogen, and H2 being molecular hydrogen). Such regions have extremely diverse shapes, because the distribution of the stars and gas inside them is irregular.

Upsweep[edit] A Brief History Of Nothing : 13.7: Cosmos And Culture Using my recent interview on To The Best Of Our Knowledge about the Krauss and the "Universe From Nothing" controversy as a pretext, I thought it would be a good idea to write a bit about what physics says of "nothing," and how this tricky notion evolved. (Here is something I wrote for 13.7 on this a few weeks back.) We may start with Aristotle, who decided that "Nature abhors a vacuum" and thus declared that there was no such thing as nothing, understood as absolute emptiness. Spaced was filled up with aether, the same stuff that made up all celestial objects, from the moon up. Aristotle was reacting to the atomists, who, before him, had declared that matter was made of indivisible atoms moving in the void.

Fuzzball (string theory) Theorized fuzzballs, like classic black holes, distort spacetime and bend light. Here, the edge of the central dark spot, the event horizon, delineates not only the threshold where its escape velocity equals the speed of light but also a fuzzball’s physical surface.

Magnetosphere in Sound One of NASA's newest missions has recorded the radio waves coming from our magnetosphere. Musicians: Sample away. A graphic of Earth's twin rings of plasma known as the Van Allen Radiation Belts in our planet's magnetosphere (NASA) Surrounding our planet are rings of plasma, part of Earth's magnetosphere, which are pulsing with radio waves. Formation and evolution of the Solar System This widely accepted model, known as the nebular hypothesis, was first developed in the 18th century by Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace. Its subsequent development has interwoven a variety of scientific disciplines including astronomy, physics, geology, and planetary science. Since the dawn of the space age in the 1950s and the discovery of extrasolar planets in the 1990s, the model has been both challenged and refined to account for new observations. The Solar System has evolved considerably since its initial formation.

Aerogel A block of aerogel in a person's hand Aerogel was first created by Samuel Stephens Kistler in 1931, as a result of a bet with Charles Learned over who could replace the liquid in "jellies" with gas without causing shrinkage.[3][4] IUPAC definition Gel comprised of a microporous solid in which the dispersed phase is a gas. Elon Musk's Mission to Mars Maverick entrepreneur Elon Musk Photo: Art Streiber When a man tells you about the time he planned to put a vegetable garden on Mars, you worry about his mental state. But if that same man has since launched multiple rockets that are actually capable of reaching Mars—sending them into orbit, Bond-style, from a tiny island in the Pacific—you need to find another diagnosis. That’s the thing about extreme entrepreneurialism: There’s a fine line between madness and genius, and you need a little bit of both to really change the world.
