The Big Bang: New Light on an Old Theory
Physics The Big Bang: New light on an old theory This lesson explores the evidence for the Big Bang theory of the origin of the Universe. In it, you will learn about the following: • Using the electromagnetic spectrum (EMS) to define radiation. • The Big Bang origin of the Universe theory. • What is the cosmic microwave background and how does this support the Big Bang theory? • Universe or Multiverse? Get ready for extragalactic time travel as we squeeze and bend our way through this space-time lesson. This is a print version of an interactive online lesson. To sign up for the real thing or for curriculum details about the lesson go to www.cosmosforschools.com Introduction: The Big Bang (P1) Scientists say they have just made a discovery that will help explain how our Universe began. If they are right, it could be the biggest, most exciting event in physics ever. Looking through a telescope into the clear skies over the South Pole, scientists spotted what they say is evidence of gravitational waves, or ripples in space-time, from the split second after the birth of the Universe – what scientists call the Big Bang. What’s got everyone so excited by this is that Albert Einstein predicted the existence of gravitational waves when he described how space and time were related and could be bent by huge forces of gravity. What the scientists at the South Pole think they saw was not gravitational waves – they would be invisible – but the effect of the waves on the light left over from the Big Bang. -

CHRIS DORAN imaginethatwe have all had occasion to look up into the sky on a clear night, gaze at the countless stars, and think about how small we are in comparison to the enormity of the universe. For everyone except Ithe most strident atheist (although I suspect that even s/he has at one point considered the same feeling), staring into space can be a stark reminder that the universe is much grander than we could ever imagine, which may cause us to contemplate who or what might have put this universe together. For believers, looking up at tJotestars often puts us into the same spirit of worship that must have filled the psalmist when he wrote, "The heavens declare the glory of God; the skies proclaim the work of his hands" (Psalms 19.1). -

The Multiwavelength Universe
Multiwavelength Astronomy Revealing the Universe in All Its Light Almost everything we know about the universe comes from studying the light emitted or refl ected by objects in space. Apart from a few exceptions, such as the collection of Moon rocks returned by Apollo astronauts, astronomers must rely on collecting and analyzing the faint light from distant objects in order to study the cosmos. This fact is even more remarkable when you consider the vastness of space. Light may travel for billions of years before reaching our telescopes. In the science of astronomy, we generally cannot retrieve samples, study objects in a laboratory, or physically enter an environment for detailed study. Fortunately, light carries a lot of information. By detecting and analyzing the light emitted by an object in space, astronomers can learn about its distance, motion, temperature, density, and chemical composition. Since the light from an object takes time to reach us, it also brings us information about the evolution and history of the universe. When we receive light from an object in space, we are actually performing a type of archaeology by studying the object’s appearance as it was when the light was emitted. For example, when astronomers study a galaxy that is 200 million light-years away, they are examining that galaxy as it looked 200 million years ago. To see what it looks like today, we would have to wait another 200 million years.

Spectra As Windows Into Exoplanet Atmospheres
SPECIAL FEATURE: PERSPECTIVE PERSPECTIVE SPECIAL FEATURE: Spectra as windows into exoplanet atmospheres Adam S. Burrows1 Department of Astrophysical Sciences, Princeton University, Princeton, NJ 08544 Edited by Neta A. Bahcall, Princeton University, Princeton, NJ, and approved December 2, 2013 (received for review April 11, 2013) Understanding a planet’s atmosphere is a necessary condition for understanding not only the planet itself, but also its formation, structure, evolution, and habitability. This requirement puts a premium on obtaining spectra and developing credible interpretative tools with which to retrieve vital planetary information. However, for exoplanets, these twin goals are far from being realized. In this paper, I provide a personal perspective on exoplanet theory and remote sensing via photometry and low-resolution spectroscopy. Although not a review in any sense, this paper highlights the limitations in our knowledge of compositions, thermal profiles, and the effects of stellar irradiation, focusing on, but not restricted to, transiting giant planets. I suggest that the true function of the recent past of exoplanet atmospheric research has been not to constrain planet properties for all time, but to train a new generation of scientists who, by rapid trial and error, are fast establishing a solid future foundation for a robust science of exoplanets. planetary science | characterization The study of exoplanets has increased expo- by no means commensurate with the effort exoplanetology, and this expectation is in part nentially since 1995, a trend that in the short expended. true.

Essential Radio Astronomy
February 2, 2016 Time: 09:25am chapter1.tex © Copyright, Princeton University Press. No part of this book may be distributed, posted, or reproduced in any form by digital or mechanical means without prior written permission of the publisher. 1 Introduction 1.1 AN INTRODUCTION TO RADIO ASTRONOMY 1.1.1 What Is Radio Astronomy? Radio astronomy is the study of natural radio emission from celestial sources. The range of radio frequencies or wavelengths is loosely defined by atmospheric opacity and by quantum noise in coherent amplifiers. Together they place the boundary be- tween radio and far-infrared astronomy at frequency ν ∼ 1 THz (1 THz ≡ 1012 Hz) or wavelength λ = c/ν ∼ 0.3 mm, where c ≈ 3 × 1010 cm s−1 is the vacuum speed of light. The Earth’s ionosphere sets a low-frequency limit to ground-based radio astronomy by reflecting extraterrestrial radio waves with frequencies below ν ∼ 10 MHz (λ ∼ 30 m), and the ionized interstellar medium of our own Galaxy absorbs extragalactic radio signals below ν ∼ 2 MHz. The radio band is very broad logarithmically: it spans the five decades between 10 MHz and 1 THz at the low-frequency end of the electromagnetic spectrum. Nearly everything emits radio waves at some level, via a wide variety of emission mechanisms. Few astronomical radio sources are obscured because radio waves can penetrate interstellar dust clouds and Compton-thick layers of neutral gas. Because only optical and radio observations can be made from the ground, pioneering radio astronomers had the first opportunity to explore a “parallel universe” containing unexpected new objects such as radio galaxies, quasars, and pulsars, plus very cold sources such as interstellar molecular clouds and the cosmic microwave background radiation from the big bang itself.
