The Trombone Sitting in a dark room there is dead silence... all of a sudden the spotlight shoots on and there in so sorrowful ...such emotion. Such beautiful music‚ the audience almost mistakes the sound as a human voice. The trombone is a musical instrument that while there were many changes throughout time can be linked back through the thresholds of the universe. However there will only be time to talk about The chemical elements and their origins‚ the creation of music‚ and the evolution of

Black holes are a very interesting and fun topic to learn about! A black hole is a hole in space that sucks things in‚ not even light can get out. These holes pull forcely because stronge matter has been squeezed into a tiny space. Light can’t get out‚ so the human eye can not see them. Scientists use special equipment for seeing black holes. The tools can see how stars around the black hole act differently than the stars away from the black hole. Black holes were first discovered in 1916 by Karl

A nebula‚ an immense cloud of hydrogen gas and dust‚ condenses into smaller regions of matter. On occasion‚ one of these regions collapses under the force of its own gravitational attraction‚ often triggered by an outside force‚ like a nearby supernova-an explosion of a star. After the collapse of a cloud‚ atoms begin gravitating together to form a condensed center. The condensed center is a protostar. As gravity pulls in more gas and dust‚ pressure builds‚ causing the protostar core to heat up

create another element‚ therefore the fusion stops. Eventually‚ the star stops producing the energy and collapses. As the core is compressed‚ the temperature of the star rises. It eventually explodes and creates what is called a Supernova. The shockwave that comes from the supernova is so powerful‚ that is forces the iron to form even heavier elements such as gold‚ platinum‚ and lead. This eventually leads to more and more elements being formed. It creates everything we see around us. Stars created

The Life Cycles of Stars In the universe‚ there are hundreds of billions of stars. They are formed when gas and dust from space "clump" together. As the mass grows larger‚ gravity takes over and a core begins to form. The core becomes extremely dense and this compaction causes temperatures within it to rise to the point where nuclear fusion (the burning of hydrogen in a chain reaction) can begin. The heat generated by fusion can reach 24 million degrees F (Fahrenheit). "That amount of heat keeps

Rand Proprietary Gold mines in South Africa~\cite{F_Reines}. \subsubsection{Neutrinos from supernovae} \label{sec:Neutrinos from Supernovae} Neutrinos are copiously emitted during stellar collapse. The first such observation of neutrinos from a supernova took place in 1987. During the early stage of stellar collapse neutrinos are produced through neutronization as following: \begin{equation} e^{-} + p \rightarrow n + \nu_{e}‚ \end{equation} \noindent where only $\nu_{e}$s are produced. The main

Monocerotis lies at a distance of 20‚000 light years from the sun and was once 60‚000 times brighter than the sun. Monocerotis is classified as a red colored variable star whose brightness changes either regularly or irregularly. V838 Monocerotis was first discovered as a brightening star by Nicholas J. Brown in Australia while he photographed an area of the sky as a part of a nova patrol (Cowen). As Brown looked at the images he had taken of the same area in the night sky for days‚ he noticed a

The Study of Celestial Objects When we were born‚ we did not know how vast the world really is‚ we were convinced that this Earth was the center‚ the only place in this world. However‚ growing up we come to accept that Earth is just a piece of the infinite universe‚ and one might even say Earth is not even an atom compared to the cosmos. It took humans thousands of years to discover the reaches of the Earth‚ we finally were able to capture the whole planet and create a map of Earth. Yet the universe
