  Mayan Astronomy: The History of...

  Many ancient civilizations have influenced and inspired people in the 21st century, and the Greeks and Romans continue to fascinate the West today, but of all the world’s civilizations, none have intrigued people more than the Mayans, whose culture, astronomy, language, and mysterious disappearance all continue to captivate people. In the past decade especially, there has been a renewed focus on the Mayans, whose advanced calendar led many to speculate the world would end on the same date the Mayan calendar ended in 2012.  
  	For the Maya, astronomy was not a purely scientific pursuit but intimately linked to religious, mythological, and ideological elements that were of the highest importance. The celestial realm held a sacred nature, as did the many gods and goddesses that dwelt there, so for all Mesoamerican cultures, astronomy was a fundamental part of their everyday lives. Thus, astronomy was present in their calendars, religion, and even agriculture, and in close relation to astronomy, the concept of time was also an essential part of their worldview. The Maya recorded time on almost every surface they could, including lintels, cornices, panels, stelae, friezes, ceramics, and paper. This insistence on capturing dates has led many scholars to suggest the Maya were obsessed with time. 
  The Maya had some of the most advanced astronomical measurements in the world, and their work built upon thousands of years, spanning from around 2500 BCE until the the arrival of the Spanish in 1519. Thanks to their hieroglyphic writing, archaeologists have been able to learn a wealth of information about the way they lived and their complex system of beliefs.

  A BRIEF HISTORY OF TIME...

  A Brief History of Time is a popular science book by Stephen Hawking that aims to explain the fundamental principles of the universe in a way that’s accessible to a general audience. It covers major topics like the Big Bang, black holes, relativity, quantum mechanics, and even the possibility of time travel. Hawking uses a friendly, often humorous tone to make complex ideas easier to grasp. 
  Main themes include:From Philosophy to ScienceHawking argues that science has taken over from philosophy as the main way we understand the universe. Through experimentation and observation, science provides more precise answers to questions that were once seen as purely philosophical or religious.The Search for a Final AnswerThe ultimate goal of science, Hawking says, is to find a unified theory that explains everything—from subatomic particles to galaxies. He sees this quest as central to human curiosity, even if it might be impossible to fully complete.The Need for Humility in ScienceThroughout the book, Hawking highlights the importance of being willing to admit mistakes and consider new ideas. Many scientists, including Einstein and Hawking himself, have revised their views as new evidence came to light. 
  The book also encourages deeper engagement through essays and reflections. In short, A Brief History of Time is a key read for anyone interested in understanding the mysteries of the cosmos and how science helps us look for answers.

  Search for Exoplanets The: The...

  While modern technology has helped astronomers view the furthest reaches of the Solar System, it has also allowed scientists to start discovering planets orbiting distant stars. To make it easier to assess the relative mass and size of the new planets being discovered, scientists give these measurements as multiples of those properties for either Jupiter or Earth. In other words, if the planet is the same mass as Jupiter, then this measure would be listed as 1.0 MJ. If it were three times the mass of Earth, then it would be listed as 3.0 MEarth. The sizes of exoplanets are frequently given by expressing their radii as multiples of Jupiter’s radius or as multiples of Earth’s radius, RJ and REarth, respectively.  
  	Of course, given the immense distances involved, detecting exoplanets has always been hard, even to this day. The variations of light that might be evidence of an exoplanet can be caused by other phenomena, and separating the false positives from the actual detections is part of the rigor required by modern planet hunters. For example, in July 1988, a Canadian team led by astronomers Bruce Campbell, Gordon Walker, and Stephenson Yang discovered persistent indications that a planet orbited the primary star in the Gamma Cephei system, 44.98 light-years (13.79 parsecs) from the Earth. Though the technique they used was successfully employed in many subsequent discoveries, the quality of their data was insufficient for others to verify as unequivocally the result of an extrasolar planet. For reasons of poor data quality, the claimed discovery of Gamma Cephei Ab was retracted in 1992.  
  	The first confirmed discovery of an exoplanet involved a system that surprised most planet hunters. While most astronomers had been looking to find planets orbiting stars in the main sequence (between infancy and old age) or in their old age (giant phase), the first confirmed planets were found to orbit a dead star.
