Frequently Asked Questions About Astronomy and Space

Astronomy and space exploration are  topics that really get people thinking about far away worlds and distant galaxies. Stargazing under a starry sky or surfing the Web looking at images from telescopes always fires up the imagination. Even though a telescope or pair of binoculars, stargazers can get a magnified view of everything from distant worlds to nearby galaxies. And, that act of stargazing spurs a LOT of questions. Astronomers get asked a lot of those questions, as do planetarium directors, science teachers, scout leaders, astronauts, and many others who research and teach the subjects. Here are some of the most-often-asked questions that astronomers and planetarium people get about space, astronomy, and exploration and collected them along with some pithy answers and links to more detailed articles!   Where Does Space Begin? The standard space-travel answer to that question puts the edge of space at 100 kilometers above Earths surface. That boundary is also called the von Kà ¡rmà ¡n  line, named after the Theodore von Kà ¡rmà ¡n, the  Hungarian scientist who figured it out. Earths atmosphere looks very thin when compared to the rest of the planet. The green line is airglow high in the atmosphere, caused by cosmic rays striking the gases up there. This was shot by astronaut Terry Virts from the International Space Station. The legal definition of space is that it begins at the top of the atmosphere. NASA How Did the Universe Begin? The universe began some 13.7 billion years ago in an event called the Big Bang. It was not an explosion (as is often depicted in some artwork) but more of a sudden expansion from a tiny pinpoint of matter called a singularity. From that beginning, the universe has expanded and grown more complex. Most depictions of the beginning of the universe show it almost as an explosion. It was really the beginning of the expansion of space and time, from a small point that contained the entire universe. The first stars formed a few hundred million years after the expansion began. Our universe is now 13.8 billion years old and measures 92 billion light-years across. HENNING DALHOFF / Getty Images What is the Universe Made of?   This is one of those questions that has an answer that is quite mind-expanding. Basically, the universe consists of galaxies and the objects they contain: stars, planets, nebulae, black holes and other dense objects.  The early universe was largely hydrogen with some helium and lithium, and the first stars formed from that helium. As they evolved and died, they created heavier and heavier elements, which formed second- and third-generation stars and their planets. This represents a timeline of the universe from the Big Bang through the present. At the left is the birth event of the cosmos, known as the Big Bang. NASA / WMAP Science Team Will the Universe Ever End? The universe had a definite beginning, called the Big Bang. Its ending is more like the long, slow expansion. The truth is,  the universe is slowly dying as it expands and grows and gradually cools. It will take billions and billions of years to cool completely and stop its expansion.   How Many Stars Can We See at Night? That depends on many factors, including how dark the skies are where. In light-polluted areas, people see only the brightest stars and not the dimmer ones. Out in the countryside, the view is better. Theoretically, with the naked eye and good seeing conditions, an observer can see around 3,000 stars without using a telescope or binoculars.   What Types of Stars Are Out There? Astronomers classify stars and assign types to them. They do this according to their temperatures and colors, along with some other characteristics.  Generally speaking, there are stars like the Sun, which live their lives for billions of years before swelling up and gently dying. Other, more massive stars are called giants and are usually red to orange in color. There are also white dwarfs. Our Sun is properly classified as a yellow dwarf.   This version of the Hertzprung-Russell diagram plots the temperatures of stars against their luminosities. The position of a star in the diagram provides information about what stage it is in, as well as its mass and brightness. A stars type depends on its temperature, age, and other characteristics plotted on diagrams such as this. European Southern Observatory Why Do Some Stars Appear To Twinkle? The childrens nursery rhyme about Twinkle, twinkle little star actually poses a very sophisticated science question about what stars are. The short answer is: the stars themselves dont twinkle. Our planets atmosphere causes starlight to waver as it passes through and that appears to us as twinkling.   How Long Does a Star Live? Compared to humans, stars live incredibly long lives. The shortest-lived ones can shine for tens of millions of years while the old-timers can last for many billions of years. The study of stars lives and how they are born, live, and die is called stellar evolution, and involves looking at many types of stars to understand their life cycles.   This is what a sun-like star looks like as it dies. Its called a planetary nebula. The Cats Eye planetary nebula, as seen by Hubble Space Telescope. NASA/ESA/STScI What is the Moon Made of?   When the Apollo 11 astronauts landed on the Moon in 1969, they collected many rock and dust samples for study. Planetary scientists already knew the Moon is made of rock, but the analysis of that rock told them about the Moons history, the composition of the minerals that make up its rocks, and the impacts that created its craters and plains. Its a largely basaltic world, which implies heavy volcanic activity in its past. What are Moon Phases? The Moons shape appears to change throughout the month, and its shapes are called the phases of the Moon.  They are a result of our orbit around the Sun combined with the Moons orbit around Earth.   This image shows the phases of the Moon and why they happen. The center ring shows the Moon as it orbits around the Earth, as seen from above the north pole. Sunlight illuminates half the Earth and half the moon at all times. But as the Moon orbits around the Earth, at some points in its orbit the sunlit part of the Moon can be seen from the Earth. At other points, we can only see the parts of the Moon that are in shadow. The outer ring shows what we see on the Earth during each corresponding part of the moons orbit. NASA Whats in the Space Between Stars? We often think of space as the absence of matter, but actual space is not really all that empty. The stars and planets are scattered throughout the galaxies, and between them is a vacuum filled with gas and dust.  The gases between galaxies are often there due to a galaxy collision that rips gases away from each of the galaxies in involved. In addition, if conditions are right, supernova explosions can also drive hot gases out into intergalactic space. Whats it Like to Live and Work in Space?   Dozens and dozens of people have done it, and more will in the future! It turns out that, aside from the low gravity, higher radiation hazard, and other dangers of space, its a lifestyle and a job.   What Happens to a Human Body in a Vacuum? Do the movies get it right? Well, not actually. Most of them depict messy, explosive endings, or other dramatic events. The truth is while being in space without a spacesuit WILL kill whoever is unlucky enough to be in that situation  (unless the person gets rescued very, very quickly), their body probably wont explode. Its more likely to freeze and suffocate first. Still not a great way to go. What Happens When Black Holes Collide? People are fascinated by black holes and their actions in the universe. Until very recently, its been tough for scientists to measure what happens when black holes collide. Certainly, its a very energetic event and would give off a lot of radiation. However, another cool thing happens: the collision creates gravitational waves and those can be measured! Those waves are also created when neutron stars collide! When two supermassive black holes collide and merge, some of the excess energy from the event is broadcast as gravitational waves. These can be detected on Earth using very delicate instruments at the LIGO observatory. The SXS (Simulating eXtreme Spacetimes) Project There are many more questions that astronomy and space spur in peoples minds. The universe is a big place to explore, and as we learn more about it, the questions will continue to flow! Edited and updated by Carolyn Collins Petersen.

The Value of Life Pro Life Free Essays

The Value of Life Imagine 3,700 children murdered in one day; their bodies torn, bruised, or poisoned. Sadly, this Is no sick fantasy, but a procedure called abortion, defined as an operation to end a pregnancy by removing an embryo or fetus from Its mother’s womb (â€Å"Choose† sec 1). In the united States alone, approximately 1. We will write a custom essay sample on The Value of Life: Pro Life or any similar topic only for you Order Now 37 million abortions occur per year. Late term abortions, or post first-term abortions, are known to cause serious health problems such as mental issues and moral dilemmas because the fetus has taken the shape ofa baby and thus is a viable human being. Abortion has een debated for centuries because of its political and social ramifications, and the correctness or lack of correctness. Both sides have strong arguments, but either way, late-term abortion should be made illegal in the United States because of its health risks, viability, and prevalence in society (â€Å"Statistics† sec 1). Late- term abortions damage both the mother’s mental and physical health dramatically. Once a fetus has taken a babys shape, the most common form of abortion Is using the combination of drugs and medicines. Methotrexate Is a drug that Is designed to kill the fetus Inside he mother’s womb; Misoprostol Is a llquld substance that Is also Involved with this abortion process. It Is used subsequent to Methotrexate and empties the uterus of the child. Medicines, like those mentioned above, are unsafe and unstable, putting the mother’s health at risk. For example, Methotrexate is known to be harmful to both the fetus and its mother (â€Å"Statistics† sec. 3). The primary use of this drug is to poison the fetus. A problem that can occur in this medicine, typically used for chemotherapy, is it can be toxic. In the case that the drug is toxic, the use in abortion can result in eath of both mother and fetus. In addition to drug toxicity, there are also many mental issues that can arise in the mother (â€Å"Abortion† sec. 3). Many become depressed because of their decision to abort; others contemplate suicide. Additionally, anxiety has affected many women who have had abortions. In a study of the after effects of abortion, 40% to 60% of women questioned gave negative reactions. This survey was done eight weeks subsequent to the procedure (â€Å"Abortion† sec. 3). Out of that percentage, 55% of them felt guilty. 4% claim they experienced ervous disorders, sleeping disorders had occurred in 36% of the women, and not surprisingly, 31% admitted feelings of regret. had to be prescribed with psychotropic pills. The high percentages of metal issues show that abortions cause serious health risks to the mothers. Adding on to mental health problems, physical complications can arise aft er an abortion (â€Å"Abortion† sec. 1). There are a multitude of â€Å"minor side effects from abortion. Small infections are a result of abortions. Many women become sick by a fever. Others experience gastrointestinal problems. Bleeding Is a very common outcome of this procedure. In the same study, women reported chronic abdominal pain, and also excessive vomltlng. Not including minor conditions, there are over 100 major problems recorded that women have faced. A DlocKage 0T an artery or emoollsm can result Trom aoortlon. some experience aeatnly infections. Hemorrhaging, or excessive bleeding, occurs in many. Ripping, or perforation of the uterus, is an excruciatingly painful result of the practice. Women can also experience anesthesia complications. In addition, cervical injury injuries are common. An astounding 5% become sterile, or unable to get pregnant again. Ectopic pregnancies may occur after one obtains an abortion (â€Å"Abortion† sec. 1). In a study of the National Rights to life Committee, two hundred and fifty-five deaths to mother’s having an abortion occur per year (McKeegan 123). Studies have shown that legal abortion is no safer than illegal, back-alley abortions. One 43year old woman bled to death during an abortion; another woman’s uterus perforated and she also passed. In addition, an eighteen year old girl had a blood infection that was fatal (Curie 52). All these major problems and more occur every year for women who abort. Although the viability of a fetus is debatable, many scientists and doctors concur that with todays modern technology, the week that a fetus becomes viable is becoming progressively earlier (Currie 26). All late-term abortions, or those occurring after twenty weeks of the pregnancy, are killing a viable fetus. Studies also show fetuses feel pain, as proven by the fact that they twisting in agony and display painful looks when aborted. Another way to show how the fetus is Just an unborn baby is the fact that its internal and external organs are the same. The fetus also performs many aby-like functions. Statistics from highly knowledgeable people have also back up the theory that a fetus is viable in post- first term state. The internal and external features show that the fetus is the same as a human, Just not as mature (â€Å"WPClinic†, sec 2). A viable fetus has the same external features of any newborn. With few exceptions, the human is made up of many different body parts such as a head, body, eyes, mouth, sex organs, hair, etc. A fetus, post-first term, has all of these typical parts and thus resembles a child. In addition to their exterior, fetuses also have the same nternal organs. They have a fully developed brain at 13-16 weeks-which is at the beginning of late 1st term. All organs are working at this point. In the latter weeks, its nervous system can even control functions (â€Å"WPClinic†, sec 2). These features prove that the fetus is Just like a newborn. Not only does the fetus resemble a newborn, it also acts like one. â€Å"The baby plays so to speak, now†¦ We know what he feels and have listened to what he hears† (McBride 34). This quote shows that a fetus is no different than a newborn baby, for it performs the same functions; the fetus is Just perhaps ot as mature. Some normal procedures the fetus performs include swallowing, making breathing sounds, recognizing its mother’s voice, blinking, grasping, kicking, and somersaulting. Physicians also say a fetus feels pain around twenty weeks (McBride 64). Today, physicians give women pamphlets to let them know their fetus will feel pain when it is aborted. Studies support this through the fact that the fetus twists in agony and shows painful looks when it is aborted (McKeegan 112). The facts prove that the fetus acts and plays like a newborn, so it should have the same rights s well. How to cite The Value of Life: Pro Life, Papers
