International Astronomy Day 2019 is on Sunday, April 28, 2019: Astronomy and revolutions in our thinking?


Sunday, April 28, 2019 is International Astronomy Day 2019.

International Astronomy Day

Astronomy enables us to determine a brief history from the world with this own eyes. The heavens that twinkle while you watch out on the dark, obvious evening might not exist at this time. They been around at whatever reason for history they released that light, that has taken countless many years to achieve Earth.Celebrate this wonderful task on International Astronomy Day by taking part inside a little stargazing. Take a look at the local planetarium or library for activities, or just look for a quiet, dark place to appear out to the sparkling canvas that lies above our heads. Use books or websites to recognize the gamers within the Universe’s spectacular, historic light show.Telescopes let us see even more than is seen towards the human eye alone. On International Astronomy Day, many organizations provide the public using telescopes to see sights from the World that they’ve never witnessed before.

Astronomy and revolutions in our thinking?

Astronomy has probably shown more clearly than most other sciences how much time, wealth, and human energy can be wasted when mankind generally pays respect to institutions that are not really respectable - faith-based religion being the premiere example of such an institution.

Astronomy has also provided an illustration of how truth eventually does come out into the light, even if deceitful or deluded people have tried to bury it for centuries. When it happens, the perpetrators of the lies and illusions may face embarrassment. Or worse. And rightly so. Cries of anti-whatever-itism won't help them then.

The sun-centered (heliocentric) theory of the solar system, combined with Newton's law of gravitation and Kepler's work on elliptical orbits produced a way to predict the positions of planets with much greater accuracy and elegance than was possible with the earlier (incorrect) theories of Ptolemaic astronomy.

The invention of the telescope made possible the degree of accuracy required for confirming the heliocentric theory of the solar system, as well as for proving that Earth is not at the center of all orbital motions. The telescope has repeatedly shown to mankind that the universe is bigger and more intricately detailed than he had previously known.

The Apollo moon landings proved that manned interplanetary spaceflight is possible, and that landings on other worlds can be done. In fact, it proved that a couple of educated cowboys can land on the moon in a primitive contraption, with a barely functional computer, by looking out through a window to see how far they've got left to drop.

The discovery that human-made chemicals were eating a hole in the ozone layer brought some people to the understanding that what people do in pursuit of near-term profits can have a longterm cost to the entire world that far outweighs the petty, selfish gains of the few. Of course, those few remain in studious denial of the significance of that discovery. Ayn Rand's writing must be a great comfort to them in these days of ecological awakening.

Artificial satellites made it possible for humans to communicate globally at the speed of light, predict the weather more reliably and with more advance warning, and provide geographical and navigational services to explorers and travelers.

Astronomy Club help??

Astronomy Club help??

Actually, they could study star charts and discuss what their members saw during the previous evenings, prior to their meetings. (Club "homework")

They may do "projects" like display personal "space" photographs taken by members.

They can make plans to view the International Space Station, as it passes over their area, or perhaps any comets or other "space" events happening that month, such as stars or planets coming close to the moon, whatever stirs their imaginations.

Some clubs may actually build their own telescopes, or at least earn how to build them.

Lots of Astronomy work, and events can not be followed during the day time on the internet. Anyone can visit NASA's website too.

"Live feeds" from space shuttle and Sky Lab are available on the NASA site and other weblinks.

Remember, that when its day time on part of the earth, the other half is still in the dark.

The list of activities for an Astronomy Club are almost endless.

Science fair projects with astronomy...?

International Dark-sky Association (IDA) has all the information you need.

There have been investigations on sky visibility and stars in the past.
