Thailand to Experience “Ring of Fire” Solar Eclipse on Sunday – Chiang Rai Times

Published

on


A partial solar eclipse will be visible in Thailand on Sunday afternoon, while sky-gazers in some other parts of Asia and Africa will be treated to a spectacular “ring of fire” event.

For those in Thailand, the moon will begin to move in front of the sun at 1.10pm local time. With maximum coverage reaching 40% at 2:48pm. The eclipse will end at 4:10pm.

Sunday’s event is known as an annular solar eclipse, in which the moon does not completely cover the sun as it passes between the sun and Earth. Instead, a ring of sunlight will still shine around the outer edge, hence the “ring of fire” name.

Viewers along a narrow band from west Africa to China will witness the most dramatic “ring of fire” eclipse in years.

Sunday’s eclipse coincides with the northern hemisphere’s longest day of the year. The summer solstice, when Earth’s north pole is tilted most directly toward the sun.

The solar eclipse will be seen first just a few minutes after sunrise local time in northeastern Congo-Brazzaville. This is the point of maximum duration, with the blackout lasting 82 seconds.

“Maximum eclipse”, with a perfect solar halo around the moon, will be reached over Uttarakhand between India and China. It will also be visible just after midday local time in Thailand.

Sky-Gazers are reminded that even if the day has turned cloudy, viewing a solar eclipse with the naked eye is dangerous. Sunglasses, which do not filter out ultraviolet rays, even more they “do not” offer any protection.

Advice on proper eye protection is available here.

What Is an Annular Solar Eclipse?

An annular solar eclipse happens when the Moon covers the Sun’s center. Leaving the Sun’s visible outer edges to form a “ring of fire” or annulus around the Moon.

In 2020, many locations will see a rare solstice annular solar eclipse on the same day as the June solstice. This will happen only twice this century, in 2020 and on June 21, 2039.

If you can’t see this eclipse from your city, don’t despair. We will be webcasting a live hosted stream of the eclipse with lots of information, images, and facts about this and other eclipses.

Moon Casts a Shadow

Solar eclipses happen when the New Moon casts a shadow on Earth.

The Moon’s shadow is not big enough to engulf the entire planet, so the shadow is always limited to a certain area. This area changes during the eclipse because the Moon and Earth are in constant motion; Earth continuously rotates around its axis while it orbits the Sun, and the Moon orbits Earth.

Solar eclipses are only visible from within the area where the shadow falls. Also the closer you are to the center of the shadow’s path, the bigger the eclipse looks.

Grizzly bears in the dark as they try to share living space with humans: study – Medicine Hat News

Published

By Bob Weber, The Canadian Press on July 7, 2020.

A grizzly bear roams an exhibit at the Woodland Park Zoo, closed for nearly three months because of the coronavirus outbreak, Tuesday, May 26, 2020, in Seattle.

EDMONTON – Grizzly bears are doing their best to get along with people, but it still isn’t enough.

Newly published research concludes that without large wilderness areas to replenish their numbers, grizzlies would disappear from landscapes they share with humans.

“The persistence of bears near people, when we see them along highways or near towns, they’re really propped up by the fact they exist near some sort of secure wilderness,” said Clayton Lamb, a University of Alberta biologist and lead author of a paper published in the Proceedings of the National Academy of Sciences.

Researchers found bears in populated areas in Alberta and British Columbia have even changed how they hunt in an attempt to share living space with humans.

“The bears are doing what they can,” Lamb said. “The difference might have to be made up by us.”

The study set out to examine an emerging phenomenon in wildlife conservation – large carnivores re-establishing themselves on mixed landscapes including cities, highways, rural communities and patchworks of natural habitat.

It digested 41 years worth of mortality, movement and demography among 2,669 grizzlies over nearly 400,000 square kilometres of British Columbia.

It found mortality has increased steeply with the amount of human impact measured through an index that includes human population, land use, infrastructure, coastlines, roads, railroads and navigable rivers.

Deaths have outnumbered births and the difference is being made up through emigration of young grizzlies from nearby wilderness. For every point the index increases, a local bear population must increase the number of individuals it draws by about two per cent.

“Grizzly bear range is quite tied to the distance from some secure piece of wilderness,” said Lamb.

That’s despite the grizzlies’ efforts to adapt to humans. The study found young, newly arrived bears gradually learned ways to avoid contact, such as hunting and gathering at night.

Adolescent bears in areas dominated by humans have increased their nocturnal time by up to three per cent annually, which has led to corresponding increases in survival. The cost, however, is steep.

The scientists found it takes 14 years for a grizzly to learn how to co-exist with humans. For every bear that makes it, 29 don’t.

“A lot of those bears would have been born on a mountaintop 10 kilometres away and lived with mom in an avalanche chute and lived a normal bear life,” Lamb said.

“Then they find a home near town and get lured in by an apple tree. The gauntlet they have to run is very difficult.”

The study shows that high mortality has impacts far from where the deaths take place. Bears dying in mixed-used areas draws more grizzlies from the wilderness to take their place.

“Conflicts with people have rippling effects on (bear) populations far removed,” Lamb said.

Highway overpasses are one good way to reduce deaths, he suggests. But humans living with bears have to get better at removing attractants such as roadkill or fruit trees to end the bears’ constant, often fatal, migration from the wilderness.

“We’re not quite there,” said Lamb. “The system relies quite heavily on adjacent wilderness.”

Odd pink snow in the Alps is pretty, but it might also be a red flag – CNET

Published

Pink snow, also called “watermelon snow,” has appeared at the Presena glacier in northern Italy, according to researcher Biagio Di Mauro of the Institute of Polar Sciences at Italy’s National Research Council. While it’s not uncommon for the Italian alps to be “pretty in pink” in spring and summer, scientists become cautious when the phenomenon, which is caused by algae, starts happening more frequently. 

Di Mauro told CNN that 2020’s lack of snowfall and higher temperatures have nurtured the algae’s growth. More algae could lead to ice melting faster.

When Di Mauro tweeted clarification for an article from The Guardian, he said the algae was probably Chlamydomonas nivalis, a snow algae. He also said the algae’s relationship with climate change hasn’t been proven yet. 

Di Mauro tweeted photos of the pink snow on Monday.

Across the ocean, in late May, Antarctica reported green snow, caused by microscopic algae. Though microscopic, the green blooms could be spotted by satellites. The color might also have connections with the impact of warming climates, researchers said.
