The Big Bang theory: It all started here! Humans have been looking up at the sky and stars, wondering how the universe all began for a long time and there are many contributors who have tried to uncover the truth about our mysterious universe including,...
There are many people who have contributed in obtaining knowledge about the universe we live in. A few that stick out to me are Carolyn S. Shoemaker, Galileo Galilei, Nicolaus Copernicus, Johannes Kepler and my favorite, Carl Sagan. Let’s begin with Carolyn...

A Little Bit about the Age of our Universe: The Wilkinson Microwave Anisotropy Probe (WMAP) satellite helped us measure our Universe by determining the parameters with an accuracy of better than 1.5%. Therefore, with the WMAP, we were able to estimate...
Our Milky Way may harbor millions of black holes... the ultra dense remnants of dead stars. But now, in the universe far beyond our galaxy, there's evidence of something far more ominous. A breed of black holes that has reached incomprehensible size and...
In this class, we read about Gravitational Lensing. I found Gravitational Lensing so interesting! There are three types of gravitational lensing: Strong Lensing: We can easily observe distortions such as the formation of Einstein rings, arcs, and multiple...

What is Gravity? Gravity is described by the general theory of relativity (proposed by Albert Einstein in 1915). Describing gravity as a consequence of the curvature of spacetime caused by the uneven distribution of mass/energy rather than describing...
To solve several important issues in cosmology, in 1981, cosmologists introduced the theory of inflation, suggesting that the early Universe expanded exponentially fast for a fraction of a second after the Big Bang. One of these issues in cosmology is...
In 1998 the Hubble Telescope (HST) allowed us to observe distant supernovae that showed us that our thinking that the universe was slowing due to gravity was false. The expansion was actually accelerating! We did not know how to explain this though. We...
Stars: A thousand years ago, humans first looked up into the dark sky and saw the stars; pinpoints of light that had seemed to slowly rotate around Earth. Over time observations have been made by astronomers and we now know more about the stars of our...
