The cosmos is offering up a double feature in August: a pair of supermoons culminating in a rare blue moon.

Catch the first show Tuesday evening as the full moon rises in the southeast, appearing slightly brighter and bigger than normal. That’s because it will be closer than usual, just 222,159 miles (357,530 kilometers) away, thus the supermoon label.

The moon will be even closer the night of Aug. 30 — a scant 222,043 miles (357,344 kilometers) distant. Because it’s the second full moon in the same month, it will be what's called a blue moon.

“Warm summer nights are the ideal time to watch the full moon rise in the eastern sky within minutes of sunset. And it happens twice in August,” said retired NASA astrophysicist Fred Espenak, dubbed Mr. Eclipse for his eclipse-chasing expertise.

The last time two full supermoons graced the sky in the same month was in 2018. It won’t happen again until 2037, according to Italian astronomer Gianluca Masi, founder of the Virtual Telescope Project.

Masi will provide a live webcast of Tuesday evening’s supermoon, as it rises over the Coliseum in Rome.

“My plans are to capture the beauty of this ... hopefully bringing the emotion of the show to our viewers,” Masi said in an email.

“The supermoon offers us a great opportunity to look up and discover the sky,” he added.

This year’s first supermoon was in July. The fourth and last will be in September. The two in August will be closer than either of those.

Provided clear skies, binoculars or backyard telescopes can enhance the experience, Espenak said, revealing such features as lunar maria — the dark plains formed by ancient volcanic lava flows — and rays emanating from lunar craters.

According to the Old Farmer’s Almanac, the August full moon is traditionally known as the sturgeon moon. That’s because of the abundance of that fish in the Great Lakes in August, hundreds of years ago.

Air pollution caused by fires is linked to more than 1.5 million deaths a year worldwide, the vast majority occurring in developing countries, a major new study said on Thursday.
This death toll is expected to rise in the coming years as climate change makes wildfires more frequent and intense, according to the study in The Lancet journal.
The international team of researchers looked at existing data on "landscape fires", which include both wildfires that rage through nature and planned fires such as controlled burns on farming land.
Around 450,000 deaths a year from heart disease were linked to fire-related air pollution between 2000 and 2019, the researchers said.
A further 220,000 deaths from respiratory disease were attributed to the smoke and particulates spewed into the air by fire, AFP said.
From all causes around the world, a total of 1.53 million annual deaths were associated with air pollution from landscape fires, according to the study.
More than 90 percent of these deaths were in low and middle-income countries, it added, with nearly 40 percent in sub-Saharan Africa alone.
The countries with the highest death tolls were China, the Democratic Republic of Congo, India, Indonesia, and Nigeria.
A record amount of illegal burning of farm fields in northern India has been partly blamed for noxious smog that has recently been choking the capital New Delhi.
The authors of the Lancet study called for "urgent action" to address the huge death toll from landscape fires.
The disparity between rich and poor nations further highlights "climate injustice", in which those who have contributed the least to global warming suffer from it the most, they added.
Some of the ways people can avoid smoke from fires -- such as moving away from the area, using air purifiers and masks, or staying indoors -- are not available to people in poorer countries, the researchers pointed out.
So they called for more financial and technological support for people in the hardest-hit countries.
The study was released a week after UN climate talks where delegates agreed to a boost in climate funding that developing countries slammed as insufficient.
It also came after Ecuador declared a national emergency over forest fires that have razed more than 10,000 hectares in the country's south.
The world has also been battered by hurricanes, droughts, floods and other extreme weather events during what is expected to be the hottest year in recorded history.
