He Charted the Moon Before Galileo, But You've Probably Never Heard of Him

Did Thomas Harriot keep his great discovery a secret to avoid decapitation?

by Eliza Strickland
Link

On a clear night in July of 1609, English polymath Thomas Harriot pointed his “Dutch perspective glass” toward the crescent moon. The crude lunar map he sketched from his observations dates him as the earliest person known to have used a telescope to study a celestial object, beating Galileo Galilei by nearly four months. Over subsequent years Harriot produced remarkable drawings showing the locations of the moon’s craters and what he believed to be its oceans and coastlines. His cartography was not bettered for decades. So why does Galileo enjoy lasting fame while Harriot has been all but forgotten?


“The unfortunate thing is that Harriot never got around to publishing his maps,” says Stephen Pumfrey, a professor of history at Lancaster University in England, “and it was definitely a publish-or-perish situation.” Since Harriot never publicly claimed to have been the first to observe the moon’s surface in detail, Galileo got the credit.

Historians debate what made Harriot so reticent. In a paper published in February [pdf], Oxford professor Allan Chapman argues that Harriot was well-off and “was not an agenda- or career-driven individual,” whereas Galileo was determined to rise in station through his science. But Pumfrey also notes that both of Harriot’s wealthy patrons ended up imprisoned in the Tower of London, which may have discouraged him from crowing about his controversial discoveries. “Harriot had no one to protect him, because his patrons were worried about having their heads chopped off,” Pumfrey says. An exhibition of Harriot’s maps opens on July 23 at the Science Museum in London.

Turn Out for Earth Hour. Vote Earth
Quote:
Earth Hour is an international event organised by the WWF (World Wide Fund for Nature/World Wildlife Fund), and held on the last Saturday of March each year, which asks households and businesses to turn off their non-essential lights and electrical appliances for one hour to raise awareness towards the need to take action on climate change. Earth hour was conceived by WWF Australia and the Sydney Morning Herald in 2007, when 2.2 million residents of Sydney participated by turning off all non-essential lights.[1] Following Sydney's lead, many other cities around the world adopted the event in 2008. [2][3]

Earth Hour will next take place on Saturday, March 28, 2009 at 8:30 pm, local time.

Space Station Construction Visible in Backyard Telescopes

This is cool, I just received it in an email, ... from Here

If youve got a telescope,
Try to find it!!
Also go to http://www.heavens-above.com/
And that will show you and tell you when the ISS and other satellites will be over your house!

March 17, 2009: Talk about a big construction project...

Astronauts are about to add a pair of 115-foot-long solar wings to the International Space Station. The station's solar arrays are the largest deployable space assemblies ever built and the most powerful electricity producing arrays in orbit. Each wing weighs 2,400 pounds, uses 32,800 individual solar cells, and adds about 4000 sq. feet of light-collecting surface area to the ISS. When the work is done, the space station will have enough usable electricity to light up 42 houses.

Amateur astronomers can see it happen with their own eyes.

The International Space Station is so large, its outlines are visible in backyard telescopes. Here, for instance, is the view through a 10-inch Newtonian reflector:

see caption

"In December, the space station made a nice pass over my backyard observatory," says photographer Ralf Vandebergh of the Netherlands. "It was about as bright as Venus—you couldn't miss it." He hand-guided his telescope to keep the ISS centered in the field of view and captured the image using a digital video camera attached to the eyepiece.

Vandebergh's snapshot shows six previously-installed solar wings--four port and two starboard. The new arrays will go on the starboard side, rounding out the eight-wing set.

Once complete, the station's power system will generate between 80 and 120 kilowatts of usable electric power. Some of that electricity is needed to operate basic space station systems, but once that is figured in, the addition of the new arrays will nearly double the amount of power available to perform scientific experiments--from 15 kilowatts to 30 kilowatts. The extra power will also double the number of full-time crew the station can support from three to six.

The new wings are en route to the ISS onboard space shuttle Discovery, which left Earth on Sunday, March 15, in a beautiful twilight launch from Kennedy Space Center. In addition to the solar arrays, Discovery is also bringing a 31,000-lb truss segment to complete the station's massive backbone and a thermal radiator to shed heat from newly-powered electronics. If all goes according to plan, the arrays, truss segment, and radiator will be installed during a spacewalk on mission Day 5 (March 19); the arrays will be unfurled accordian-style on mission Day 8 (March 22).

The timing of these events favors sky watchers in the USA and Canada. The ISS (with Discovery docked) is due to fly over many North America towns and cities after sunset in mid- to late-March. Shining brighter than any star, the ISS-Discovery combo takes a leisurely 5 minutes to glide across the sky--plenty of time to point a telescope, take a picture, or just soak up some of the station's growing luminosity.

My Spaceship/Time Machine/ Telescope..

Hey internetters.... lol

Just posting a little on my Telescope/spaceship/time machine,
and a picture or two of it. :-)

It is a Meade DS-2114ATS-LNT 114mm 4.5" AutoStar Computer GoTo Altazimuth Reflector Telescope. found Here..

My Mother bought it for me for this past Xmas ('08),
ever since i was little, she would always try to have at least one Big gift, amongst all the others,
and to this day.. ( almost 29 years later), She still does it. I could write you a book on her,
but that's for another time, another place m'friends. lol But She is an angel, and i love her. <3

so This is my new joy,
<3 <3 <3

I have spent many hours with this telescope already so far,
and a whole lot more to come.
It is such a joy to be able to go out and find any heavenly body we choose...
and then to be able to zoom in on it!! :D

sometimes.....
when staring at the moon through it with my 9mm eyepiece,
it feels like i am hovering or floating above it, just watching it all. lol
like as if i was in a spaceship looking out the windows. lol
i feel like a kid again with all this. lol :)

Peace Love n Clear Skies. <3

Monday, March 16, 2009

Brrrrrrrrr...... but its ok...... lol



I was outside last night for hours....
I set up the scope around 6 or 7.. while Venus was still up in the sky,
and my friend and i looked at her for awhile, it was still light out.

by the time i brought the telescope inside,
it was like 3 or 4 am. lol :P

it got c c ccoollldddd after awhile..(see the car? lol) but... i had tea, and herbs and stuff to keep me warm, so i didnt think about the cold much,
but i did start shivering allot by the time i came in,
thats what made me come in. lol

<<<<---------------------<< Here is a Moon shot from last night, Im still only using my primitive method of holding my camera (Sony Cybershot) up to the eyepiece of the telescope. lol I will get the proper gear for all this stuff one of these days. lol


I also watched M42 for a good hour or so... Ill have to make a sketch, as i cant get pics of it yet,
but it is beautiful!! <3


then I watched Saturn for a long time last night also, I didnt get any pics.. ( still difficult with my method) lol..
and I dont have a Barlow yet, as soon as i get that, it will be sweet!! lol :P

Sirius and Arcturus and many others were also viewed,
so beautiful..
I think when we look at them, and actually see them as they are ( Stars, Planets, nebulae, etc)...
it is like making contact with them... in a way.. lol
tis a beautiful thing.



Thanks for checking this out. ( if anyone is even checking it out?!) haha :P

I got some cool stuff to post up. (about the Universe) woohoo!! lol :P

Peace , Love, and Clear Skies!! :D

The IYA2009 telescope is now available!

for those who dont have a telescope...
IYA is doing this... :) IYA2009 Telescope

The Galileoscope™: An IYA2009 Cornerstone Project




News Release - IYA0906: Galileoscope in production: The IYA2009 telescope is now available!

Mar 4, 2009, Paris

The Galileoscope — a high quality, easy-to-assemble and easy-to-use telescope at an unprecedentedly low price — is now available to order. A Cornerstone project of the International Year of Astronomy 2009 (IYA2009), the Galileoscope was developed by a team of leading astronomers, optical engineers and science educators to make the wonders of the night sky more accessible to everyone. Orders can now be placed through www.galileoscope.org for delivery beginning in late April.

By encouraging the experience of personally seeing celestial objects, the Galileoscope project aims to facilitate a main goal of IYA2009: promoting widespread access to new knowledge and observing opportunities. Observing through a telescope for the first time is an experience that shapes our view of the sky and the Universe. It prompts people to think about the importance of astronomy, and for many it's a life-changing experience. Galileoscopes will open up a whole new world for their users and are an excellent means of pursuing an interest in astronomy during IYA2009 and beyond.

Galileoscopes are available at the incredibly low price of US$15 per kit. Discounts are available for group purchases of 100 or more, bringing the price down even lower, to US$12.50 each, reducing costs for schools, colleges, astronomical societies, or even parties of interested individuals. Never before has such a high quality and professionally endorsed scientific instrument been available for this price.

To further this aim, the Galileoscope Cornerstone project has initiated the "Give a Galileoscope" programme. Participants may buy Galileoscopes for themselves, their families, or their friends at the regular $15 or $12.50 price (depending on quantity) plus shipping, and/or donate as many telescopes as they'd like for $12.50 each, with no shipping charges. Donated Galileoscopes will go to less advantaged schools and other organisations worldwide, especially in developing countries. This will help bring a modern education to students in poor schools and empower them to pursue science and technology knowledge. Donating Galileoscopes increases the project's global impact and gives people who might otherwise never have the opportunity to look through a telescope the chance to join millions of skywatchers worldwide in a shared experience of astronomical discovery.

The Galileoscope is named after the Italian astronomer Galileo Galilei, who first observed the heavens through a telescope 400 years ago. His observations were nothing short of revolutionary and changed our view of the world forever. The Galileoscope is optimised to provide views of the very same objects that inspired Galileo all those years ago- including craters and mountains on the Moon, the rings of Saturn, the phases of Venus, a variety of star clusters, and moons orbiting the planet Jupiter. Sights such as these astounded Galileo and they are all visible, along with countless other objects, through the Galileoscope. Although, with its 21st-century optics, it will provide a much better observing experience than Galileo had!

Galileoscopes are also invaluable educational tools, tying in with topics such as mathematics, physics, history and philosophy. As practical instruments they can be used to demonstrate basic optical theory in a real-world scenario, a technique often praised by educators and pupils themselves. Free educational guides are available on the project's website, providing further information to teachers, students and enthusiasts. Experience has shown that the "Wow!"-factor that kids get from assembling their own fully functional, high quality Galileoscope is unsurpassed.

"The ability to experiment with lenses while building the telescope offers a much more powerful learning experience than receiving a preassembled telescope," says Rick Fienberg, Editor Emeritus of Sky & Telescope magazine and Chair of the IYA2009 Cornerstone project. "Users will learn many aspects of optics and even have a chance to construct two types of telescopes - a modern one and a more primitive one similar to Galileo's," adds Stephen Pompea, US IYA2009 Project Director and member of the IYA2009 Cornerstone project. "Building and using a Galileoscope gives kids the feeling that science is fun."

Galileoscopes are easy to use, sturdy, reliable and well-designed windows to the Universe. Orders are now being taken through the official website, www.galileoscope.org. Build one and the stars will be within your reach!

Worldwide observing projects with small telescopes are a key part of the Galileoscope Cornerstone. The "You Are Galileo!" project, organised by the IYA2009 Japan National Committee, uses classroom telescopes along with worksheets and manuals to form part of a year-long observation programme. These are designed for children and certificates are available for participants who send records of their observations to the "You Are Galileo!" team.

Notes for Editors
The Galileoscope is a high quality 50-mm f/10 telescope, with a glass doublet achromatic objective. A 20-mm Plössl-like eyepiece with twin plastic doublet achromatic lenses gives a magnification of 25x across a 1.5-degree field, and a 2x Barlow lens (also a plastic doublet achromat) gives a magnification of 50x. The Barlow lens can also be used as a Galilean eyepiece to give a magnification of 17x and a very narrow field of view to simulate the "Galileo experience". The standard 1.25-inch focuser accepts commercial accessories, and the standard 1/4-20 tripod adapter works with any standard photo tripod (not included).

In addition to the IAU, UNESCO, the IYA2009 Global Sponsors and the IYA2009 Organisational Associates, principal sponsors of the Galileoscope project include the American Astronomical Society, the National Optical Astronomy Observatory, the National Science Foundation, the Astronomical Society of the Pacific, Carthage College, Merit Models, Photon Engineering, Sky & Telescope, and Galileo's Place, home of Galileo-brand telescopes.

IYA2009 marks the 400th anniversary of Galileo Galilei's first astronomical observations through a telescope. It is a worldwide celebration, promoting astronomy and its contribution to society and culture, with events at regional, national, and global levels.

International Year of Astronomy~ 2009~

About IYA2009 http://www.astronomy2009.org/general/

The International Year of Astronomy 2009 (IYA2009) is a global celebration of astronomy and its contributions to society and culture and marks the 400th anniversary of the first use of an astronomical telescope by Galileo Galilei. The aim of the Year is to stimulate worldwide interest, especially among young people, in astronomy and science under the central theme "The Universe, Yours to Discover". IYA2009 events and activities will promote a greater appreciation of the inspirational aspects of astronomy that embody an invaluable shared resource for all nations.

Image Image Image

The IYA2009 activities are taking place at global and regional levels, and especially at the national and local levels. National Nodes in each country are running activities throughout the year, aimed at establishing collaborations between professional and amateur astronomers, science centres, educators, and science communicators.


Welcome

Catherine Cesarsky
IAU President

The International Astronomical Union (IAU) launched 2009 as the International Year of Astronomy (IYA2009) under the theme, The Universe, Yours to Discover. IYA2009 marks the 400th anniversary of the first astronomical observation through a telescope by Galileo Galilei. It will be a global celebration of astronomy and its contributions to society and culture, with a strong emphasis on education, public engagement and the involvement of young people, with events at national, regional and global levels throughout the whole of 2009. UNESCO has endorsed the IYA2009 and the United Nations proclaimed the year 2009 as the International Year of Astronomy on 20 December 2007.

Astronomy is one of the oldest fundamental sciences. It continues to make a profound impact on our culture and is a powerful expression of the human intellect. Huge progress has been made in the last few decades. One hundred years ago we barely knew of the existence of our own Milky Way. Today we know that many billions of galaxies make up our Universe and that it originated approximately 13.7 billion years ago. One hundred years ago we had no means of knowing whether there were other solar systems in the Universe. Today we know of more than 200 planets around other stars in our galaxy and we are moving towards an understanding of how life might have first appeared. One hundred years ago we studied the sky using only optical telescopes and photographic plates. Today we observe the Universe from Earth and from space, from radio waves to gamma rays, using cutting edge technology. Media and public interest in astronomy have never been higher and major discoveries are frontpage news throughout the world. The IYA2009 will meet public demand for both information and involvement.

There are outstanding opportunities for everyone to participate in the IAU IYA2009 events.

The IAU, UNESCO and our Organisational Associates wish everyone a year rich in astronomical experiences as we all celebrate the International Year of Astronomy 2009!
