To track the passage of time, mankind created time zones and a date line where one day ends and another begins.
American scientist Cameron Hummels from the California Institute of Technology said that for the first time on Earth you will see the sunrise. Live Science writes about it.
According to him, from a physical point of view, there is no first sunrise, but there is a whole series of eternal sunrises.
“From this point, the first sunrise occurs on the international date line,” Hummels said.
He said that this line passes through the middle of the Pacific along the 180th meridian east longitude. It is a straight line, with a slight deviation. So, a country cannot be in two time zones at the same time.
“To keep track of time, mankind created time zones and a date line where one day ends and another begins. For example, the date line runs about 3,200 km from the island nation of Kiribati, with earliest time. zone on Earth Based on this, for most of the year, for example, at the equinoxes, Kiribati should have the first sunrise. known as Caroline Island, which is part of Kiribati,” added Hummels.
Although, according to him, this does not always happen. Due to the fact that our planet has an inclination of 23.5 degrees, the direction of sunlight falling on the Earth changes throughout the year.
“During the southern summer solstice and northern winter solstice on December 21 or 22, the Sun usually rises at the Tropic of the South (23rd parallel south latitude), while the South Pole and most of Antarctica are illuminated 24 hours a day. a day. But if there is a little North of 66 degrees S, the Sun sets here briefly before rising just a few minutes after midnight, so the uninhabited Young Island claimed by New Zealand sometimes sees the first sunrise in days close to the solstices, including the first sunrise of the New Year, that is, January 1,” said the scientist.
From the claims that on Young Island the first sunrise occurs only 10-15% of the time. The rest of the time is 24/7 sunlight.
“The sun shines more directly in the northern hemisphere than in the southern hemisphere. Therefore, the first sunrise will be north. The date line runs between Russia and Alaska (US state) through the Bering Strait. Divided by on this line are two islands – the Diomede Islands. Big Island Diomede belongs to Russia, and Small Diomede belongs to the US. A few weeks and even months before June 21, the first sunrise on the planet will be seen on the Russian island ,” Hummels concluded.
Recall that earlier NASA published a photo of the rising Sun over the Earth, taken on August 10 by one of the astronauts from the International Space Station.
