An Astronomical Evening in the Planetarium

2015-3-21 (Sat) 18:00 - 20:30

As can be seen from the establishment of the first planetarium in Japan in 1937, Osaka has had a deep fascination with the universe for a very long time. For this lecture, with the help of the Osaka Science Museum, we'll take an astronomical look at the night sky using planetarium projections.

For the first half of the lecture, we'll talk about the formation of planets from both inside and outside of the solar system by taking an on-the-spot look at the birth of stars through the latest observational equipment, and we'll also delve into what meteoric stone analysis can tell us about the history of the solar system. During the second half of the lecture, we'll discuss the growth of the multitude of black holes, as well as examining the history of the universe.

Please enjoy this planetarium lecture by leading astronomical researchers!

The content to be covered in this lecture is aimed at those of high school age and up; however, anyone may register and join this lecture.

Lecture Overview

Lecture 1 -- Closing in on the Birth of Extrasolar Planets Using the Latest Observation Technology, FUKAGAWA Misato (Assistant Professor, Graduate School of Science, Osaka University)

There are many planetary systems in the universe, but how did they, including our own solar system, come to be? To examine this mystery, there has been large activity in the observation of newborn stars and their surroundings, leading to our current understanding and ongoing pursuit of just how planets forms. We will introduce observational results mainly taken from Japanese telescopes.

Lecture 2 -- "The History of the Solar System through Meteoric Stones," TERADA Kentaro (Professor, Graduate School of Science, Osaka University)

About 4.6 billion years ago, the solar system was born from nebular gas, a collection of gases and dust. Even though the 8 planets were born during the same period from the same material, they are all very unique, with the earth being the only one with thriving oceans and life. So how were the attributes of each planet decided, and when? We'll discuss the latest analysis of meteoric stones and how this analysis can show us the history of the solar system.

Lecture 3 -- "Why did the Universe make Black Holes?" TANIGUCHI Yoshiaki (Professor and head of the Ehime University Cosmic Evolution Research Center)

There are many, many black holes in the universe. But, how many would you say exist? A couple hundred million? Not even close. There are hundreds of billions of black holes in the universe. Not even light can pass through these holes in the universe. So why, then, did the universe make something like these? Come join me in looking for the answer together. The answer lies in the distant future.
