How Blind Astronomers Will Observe the Solar Eclipse

  How Blind Astronomers Will Observe the Solar Eclipse Like millions of other people, Wanda Diaz Merced plans to observe the August 21 total solar eclipse, when the moon’s shadow will sweep across the sun and, for a few brief moments, coat parts of the United States in darkness.  Diaz Merced, an astrophysicist, is blind, with just 3 percent of peripheral vision in her right eye, and none in her left. She has been working with a team at Harvard University to develop a program that will convert sunlight into sound, allowing her to hear the solar eclipse. The sound will be generated in real time, changing as the dark silhouette of the moon appears over the face of the bright sun, blocking its light.

If you you’ve never seen a solar eclipse before, you should make an effort to witness the breathtaking event on August 21. While only people in the US will be able to see the total eclipse – in which the moon completely blocks the light from the sun – those living in parts of South America

From a typical spot on earth, a total solar eclipse will only occur once every four hundred years on average. Fewer than one in four people in the past, lacking the benefit of modern scientific foreknowledge and travel possibilities.

While only people in the US will be able to see the total eclipse – in which the moon completely blocks the light from the sun – those living in parts of South America, Africa and Europe should be able to see at least a partial solar eclipse.

Solar eclipses occur when the moon passes between the Earth and the sun so that it blocks part or all of the sunlight as viewed from a particular location on our planet. Earth is the only planet in the solar system where this can happen in this way. This is because of the moon’s size and its relative distance from the sun – when viewed from the Earth, it can identically cover the bright solar disc to reveal the tenuous, wispy outer atmosphere of the star (called the solar corona).

What Solar Eclipses Have Taught Us About the Universe

  What Solar Eclipses Have Taught Us About the Universe Total solar eclipses like the one that will cross the U.S. on Aug. 21 have captured the attention of astronomers throughout history — and have often led to advances in our understanding of how the universe works. Astronomers have been studying solar eclipses for centuries. In the late 16th and early 17th centuries, Danish astronomer Tycho Brahe and his apprentice German astronomer Johannes Kepler studied eclipses to try to arrive at a rough estimate of the moon’s diameter.

An eclipse does not happen every time the moon travels around the Earth. This is because its orbit has a slight inclination (about five degrees) relative to our planet’s journey around the sun. However when aligned correctly, the result is an awesome, emotional experience. Once the eclipse has begun, the moon continues to eat its way across the blazing sun before darkness falls, the temperature drops and the sky is dominated by a radiant crown around the moon. It happens approximately every 18 months.

On August 21, the moon’s shadow will travel west to east, touching land at Lincoln Beach, Oregon at 09:05 Pacific Daylight Time before speeding across North America at up to 1km per second and finally exiting close to Charleston, South Carolina, at 16:09 Eastern Daylight Time. The longest total eclipse will occur close to the town of Carbondale, Illinois – lasting about two minutes and 40 seconds.

Anywhere within the 110km wide path of the eclipse, observers will be able to see the sun completely covered. Outside of that, sky-watchers will still see a partial eclipse with decreasing percentages of the sun’s surface covered as one moves away from this narrow corridor. It is estimated that over 12m Americans live in the path of the total eclipse itself and another 200m people within a day’s drive of it. This is science engagement on an unprecedented scale and is likely to be the most orchestrated eclipse viewing event ever undertaken.

Digital deluge

Social media activity has been increasing for months now, building up the anticipation to be part of this rare event. Expect Twitter, Facebook, Snapchat, Flickr and Instagram to be swamped with eclipse pictures during and after the event. In fact, the eclipse should be one of the most digitally recorded events ever, which could be of use to scientists. The Citizen CATE (Continental-America Telescopic Eclipse) experiment aims to capture images of the inner solar corona using a network of more than 60 telescopes operated by citizen scientists, high school groups and universities.

Total Solar Eclipse 2017 - On Monday, August 21, 2017, all of North America will be treated to an eclipse of the sun. Anyone within the path of totality can see one of nature’s most awe inspiring sights - a total solar eclipse .

The total solar eclipse on August 21, 2017 is a rare phenomenon that offers many gifts for humanity. When an eclipse does occur, totality never exceeds a mere seven minutes, 30 seconds—and it’s usually much shorter.

Similarly, the Eclipse Mega-movie is asking observers to use their app to upload eclipse images along the path of totality to produce an expanded and continuous film of the total eclipse as it crosses the country. Both of these experiments will produce unique data-sets of the white light corona, a region that is usually impossible to observe because the exceptionally bright solar disc hides it from view. We will be able to examine like never before the detailed structure of the solar corona and how it is dragged out into space by the solar wind.

There is also a big focus on education. A top priority is making sure that people know how to safely view the eclipse. Looking directly at the sun is unsafe except during that brief period of the total eclipse. It is vitally important that only special solar filters, such as certified eclipse glasses, are used. Unfiltered cameras, telescopes, binoculars or other optical devices concentrate the solar rays and are a definite no-go in regard to eye safety. If no filters are available, it is best to use a pinhole camera to project the eclipse indirectly.

Next week’s total solar eclipse isn’t just a chance to see a cool natural phenomenon, it’s a rare opportunity for all kinds of science experiments. The path of a total solar eclipse hasn’t touched

The science of eclipses . Total eclipse seen from Africa, 2001. Co-ordinated eclipse -space observations. In this era of orbiting solar observatories, is there still a scientific benefit in making eclipse observations from Earth?

It is also important to take advantage of the amazing opportunity to inform a huge population about the science behind the event. There are thousands of astronomy-oriented events, parties even, being hosted along the path of totality.

New science?

Scientists are equally excited. Eleven NASA and NOAA satellites, high-altitude balloons, hundreds of ground-based telescopes and even the International Space Station will all take advantage of this unique shadow-chase across the surface of the Earth. However, it is not just looking up at the moon and sun that is important. Total eclipses also provide us with an unprecedented opportunity to examine our own planet under quite unusual conditions.

NASA says that observers across several states will measure the radiant energy from the sun into the Earth’s atmosphere from the ground as well as from space. This should provide new insights into how the incident solar energy in our atmosphere changes when particles, clouds and in this case the moon, prevents sunlight from reaching the surface of the planet.

I will be fortunate enough to be part of a four-hour live online telecast of the eclipse from Carbondale via NASA’s video podcast EDGE. This will include interviews with scientists and live panel questions, high-resolution sun images and a balloon launch. As a solar physicist who can only usually observe the solar corona from space by satellite instrumentation, it is special to be able to glimpse the corona with the (protected) naked eye for a brief time.

The total eclipse on August 21st, 2017 will be one of the most viewed in history. Observers will see the normally hidden loops and streamers of the solar corona, and as the eclipse approaches totality , the temperature will drop, stars will appear in the For its many benefits , projection can invite error.

One interesting part to all this is the fact that the US gets another chance in seven years to maximize the opportunities that the eclipse brings.

It is said that one of the longlasting legacies of the Apollo missions to the moon is the number of American scientists today who were inspired to be engineers and scientists. Though this solar eclipse is science engagement in a different manner, the end goal is the same – bringing about not just a greater appreciation of the Earth, and solar or lunar research, but also sparking a desire in many young people to be the science leaders of the future.
