Announcement: This Saturday at The Science Circle - "Understanding Science: Earth and the Solar System"

 

"Understanding Science: Earth and the Solar System" 

Saturday April 17

10AM to 11 AM

From the bizarre world of the very small, the subatomic particles that make up everything we know, we turn our attention to the macro world, namely our sun and the objects which orbit it. In this case, one of the small particles within this ‘atom,’ just one among a billion other star systems that comprise our galaxy, itself only one of billions of other galaxies in our known universe, is the only home we have, the ‘third rock from the sun’ we call Earth.

I do not think humans really appreciated how special the Earth is until we were able to travel beyond it. I remember during the Apollo 8 mission, the first that time humans left Earth’s gravity, how the contrast of the ‘blue marble’ in space rising over the drab, lifeless moon brought a stark realization to everyone who witnessed it that we live on a fragile, ‘goldilocks’ planet with just the right conditions to make the surface habitable for life as we know it. It was this realization that inspired Earth Day in 1970 and the movements since to preserve what we have here for future generations.

During the 1960’s, space exploration seemed part of the Space Race and Arms Race, a product of the Cold War. After a few missions to the moon, humans have not ventured outside Earth’s orbit. However, robotic spacecraft have not only helped us to better understand our home planet but have also probed deep into space and the worlds beyond ours to try to understand our place in the universe, to answer the questions of how unique our planet is, whether there may be life elsewhere, and to understand how it all began.

In recent years, there has been a resurgence of interest in space exploration. In just this last year there have been three missions to Mars, and several more to our Moon, the Sun, and the smaller bodies of the solar system, by a handful of nations, not just the Cold War rivals. There are also several commercial entities planning serious efforts to exploit the resources on the moon and beyond, and cooperative efforts to put a space station around the Moon, with a base on the surface to follow.

Join me as we explore how we ventured out beyond our home and the amazing discoveries we have made about our solar system and its inhabitants and the world beyond, some exciting recent and current plans for further exploration, and what all this might mean for our future.

Announcement: This Week At The Science Circle: "Copernicus’ Epicycles"


“Copernicus’ Epicycles”
Saturday March 3 at 10:00 AM - 11:00 AM SLT
by Rob Knop

Nicolaus Copernicus (1473-1543) is sometimes called the father of modern astronomy. He’s famous for introducing to Western Europe a thorough and worked-out model of the Solar System with the Sun at the center. At the time, nearly everybody accepted Ptolemy‘s Earth-centered model, with planets riding on celestial spheres, and riding on epicycles inside those spheres. Many of us carry the idea that Copernicus simplified it all by moving the Sun to the center. It turns out, however, that Copernicus’ system is not appreciably simpler than Ptolemy’s — he, too, had epicycles in his model! Nor was Copernicus the first one to think about Sun-centered models of the Solar System, as that idea goes back at least to ancient Greece.
  In this talk, I will outline the history of our understanding of the Sun-centered model of the Solar System, and give some detail about how Copernicus’ model worked, and why it took the work of others later for us to really accept that his basic idea was right.

“Voyager and Cassini - Where No One Has Gone Before!”
          
By Phil Youngblood Ph.D


Reality begins with a vision. Over 50 years ago, a NASA JPL scientist realized that a rare alignment of planets to take place years in the future could be exploited by a spacecraft using Jupiter’s gravity to slingshot itself to the outer planets and beyond. That vision led to the Pioneer, Voyager, Cassini, and New Horizons missions that left us spellbound with wonder as these craft gave us a closeup view of the worlds that are our neighbors. Join me this Saturday for a personal journey from our ‘pale blue dot’ to the outer reaches of our solar system, a journey that continues to go where no one has gone before!

Announcement: UH Astronomy: "New Discoveries in the Solar System"



Our ancestors could see Solar system objects with their naked eyes. Mercury, Venus, Mars, Jupiter and Saturn were the planets known in ancient times. In 1609 Galileo Galilei made the first recorded astronomical observations with a telescope. One year later he was the first person to observe Saturn’s rings. Uranus was discovery in 1781 and in 1977 Keck telescope in Hawaii observed rings around Uranus. Neptune was discovered in 1846 and in 1977 a telescope in Chile discovered that Neptune also has rings. Voyager 1 spacecraft found rings around Jupiter in 1979. Voyager 2 discovered more rings around Uranus and Neptune in the 80’s. In this talk we will talk about general proprieties of solar system objects including planets, comets and moons and a technique called stellar occultation that led the discovery for the first time of rings around an asteroid by a group of scientists that includes the speaker.
