Total Solar Eclipse 2024: Live Updates

Total Solar Eclipse 2024: Live Updates

  • Post category:Science

For centuries, people have been clamoring to glimpse solar eclipses. From astronomers with custom-built photographic equipment to groups huddled together with special glasses, this spectacle has captivated the human imagination.

In 1860, Warren de la Rue captured what many sources describe as the first photograph of a total solar eclipse. He took it in Rivabellosa, Spain, with an instrument known as the Kew Photoheliograph. This combination of a telescope and camera was specifically built to photograph the sun.

Forty years later, Nevil Maskelyne, a magician and an astronomy enthusiast, filmed a total solar eclipse in North Carolina. The footage was lost, however, and only released in 2019 after it was rediscovered in the Royal Astronomical Society’s archives.

Telescopic Vision

For scientists and astronomers, eclipses provide not only an opportunity to view the moon’s umbra and gaze at the sun’s corona, but also to make observations that further their studies. Many observatories, or friendly neighbors with a telescope, also make their instruments available to the public during eclipses.

Indirect Light

If you see people on Monday sprinting to your local park clutching pieces of paper, or with a cardboard box of their head, they are probably planning to reflect or project images of the solar eclipse onto a surface.

Cynthia Goulakos demonstrated a safe way to view a solar eclipse, with two pieces of cardboard to create a reflection of the shadowed sun, in Lowell, Mass., in 1970.

Another popular option is to create a pinhole camera. This woman did so in Central Park in 1963 by using a paper cup with a small hole in the bottom and a twin-lens reflex camera.

Amateur astronomers viewed a partial eclipse, projected from a telescope onto a screen, from atop the Empire State Building in 1967.

Back in Central Park, in 1970, Irving Schwartz and his wife reflected an eclipse onto a piece of paper by holding binoculars on the edge of a garbage basket.

Staring at the Sun (or, How Not to Burn Your Retinas)

Eclipse-gazers have used different methods to protect their eyes throughout the years, some safer than others.

In 1927, women gathered at a window in a building in London to watch a total eclipse through smoked glass. This was popularized in France in the 1700s, but fell out of favor when physicians began writing papers on children whose vision was damaged.

Another trend was to use a strip of exposed photographic film, as seen below in Sydney, Australia, in 1948 and in Turkana, Kenya, in 1963. This method, which was even suggested by The Times in 1979, has since been declared unsafe.

Solar eclipse glasses are a popular and safe way to view the event (if you use models compliant with international safety standards). Over the years there have been various styles, including these large hand-held options found in West Palm Beach, Fla., in 1979.
