Rare blue moon expected on Halloween – CTV News

Published

 on


TORONTO —
Trick-or-treaters around the world will be treated to more than candy this Halloween as a rare blue moon is expected to illuminate the sky Saturday night. 

The spectacle occurs when two full moons coincide in the same calendar month, and this year it will be visible in every time zone.

 

WHY IS IT CALLED A BLUE MOON?

Despite its name, the moon’s colour is not actually blue. Instead, a blue moon is a common way to refer to the second full moon in October, as the first is typically referred to as a harvest moon.

However, there is also an alternate definition of a blue moon that says it is the third full moon of four occurring in a single season, according to NASA.

 

HOW RARE IS A BLUE MOON?

Contrary to the saying, blue moons are not all that uncommon as they occur every 2.5 years in different time zones.

What makes this blue moon so rare is that it will be seen in every time zone. The last time that happened was in 1944, according to the Farmer’s Almanac.

On top of that, it’s happening on Halloween, making the phenomenon that much rarer.

On average, blue moons appear on Halloween once every 19 years and are only visible to those who live in certain time zones. The last full moon that appeared on Halloween was on Oct. 31, 2001 and it was only seen by people in central and Pacific time zones.

“Any time the moon is technically full on October 31, it will also have to be a blue moon because the lunar cycle is only 29.5 days long,” the Farmer’s Almanac’s website states.

People who live towards the east of the international date line will see this full moon on Nov. 1 and will have a blue moon at the end of November as it will be their second full moon of the lunar cycle.

Blue moons are a direct result of the lunar cycle. Since the cycle is shorter than most calendar months — lasting only 29.5 days — blue moons are bound to eventually occur in October.
The next blue moon is expected fall on Halloween in 2039.

NOAA scientists discover new species of gelatinous animal near Puerto Rico – CTV News

Published

 on


Scientists have discovered a new species of ctenophore, or comb jelly, near Puerto Rico.

The newly named Duobrachium sparksae was discovered two and a half miles below sea level by the National Oceanic and Atmospheric Administration Fisheries research team. It was found during an underwater expedition using a remotely operated vehicle in 2015 and filmed by a high-definition camera.

NOAA Fisheries scientists Mike Ford and Allen Collins spotted the ctenophore and recognized it as a new species. This is the first time NOAA scientists have identified a new species using only high-definition video, according to NOAA.

“The cameras on the Deep Discoverer robot are able to get high-resolution images and measure structures less than a millimeter. We don’t have the same microscopes as we would in a lab, but the video can give us enough information to understand the morphology in detail, such as the location of their reproductive parts and other aspects,” Collins said.

The scientists also said there was another unique quality to the discovery. During the expedition, they were not able to gather any samples, so the video evidence is all they have.

“Naming of organisms is guided by international code, but some changes have allowed descriptions of new species based on video — certainly when species are rare and when collection is impossible,” Ford said. “When we made these observations, we were 4,000 metres down, using a remote vehicle, and we did not have the capabilities to take a sample.”

There are between 100 and 150 species of comb jellies, and despite their name, they are not related to jellyfish at all, according to the NOAA. The species is carnivorous, and many are highly efficient predators that eat small arthropods and many kinds of larvae.

The researchers said that there did not initially get a long look at the animal, so there is still a lot about this new species that they do not know yet. Their findings were recently published in the journal Plankton and Benthos Research.

“We’re not sure of their role in the ecosystem yet,” Ford said.

“We can consider that it serves similar roles to other ctenophores near the ocean floor and it also has some similarities to other ctenophores in open ocean areas,” he said.

The videos are now part of the Smithsonian National Museum of Natural History Collection and publicly accessible.

You might want to stay up late: lunar eclipse to coincide with November’s Beaver full moon early Monday morning – Toronto Star

Published

 on


A special celestial event is set to grace Toronto skies early Monday morning.

The November full moon, which is traditionally called the Beaver moon, will coincide with a penumbral lunar eclipse.

This kind of eclipse event happens when the moon crosses Earth’s outer shadow, or penumbra, giving it a reddish brown hue.

Those in Toronto will be able to observe the phenomenon starting 2:29 a.m. ET. The eclipse will be at its peak at 4:42 a.m. ET.

Environment Canada predicts partly cloudy skies at that time, but stargazing enthusiasts may be able to get a glimpse of the moon.

Although the Canadian Space Agency notes lunar eclipses are usually among the most observable because you can see them — quite safely — with the naked eye, with the more subtle penumbral eclipse they recommend using binoculars or a small telescope for the best viewing experience.

The fourth and last lunar eclipse of 2020, a penumbral eclipse, will occur on November 30 (Monday).

According to Prof Dr Javed Iqbal, of the Institute of Space and Planetary Astrophysics (ISPA), University of Karachi, the eclipse will take place at 12:32pm according to Pakistan Standard Time.

The lunar eclipse will be seen in South and North America, Australia and Asian countries and will not be seen anywhere in Pakistan.

It will reach its peak at 2:42pm, Dr Iqbal said, adding that the shadow of the eclipse will be removed from the moon at 4:53pm.

The total duration of the eclipse will last 4 hours and 21 minutes, Dr Iqbal said.

The last three lunar eclipses occurred on January 10, June 5, and July 4.

A penumbral eclipse occurs when the Earth blocks some of the sun’s light from directly reaching the moon’s surface. All or part of the moon is covered with the outer part of its shadow, also known as the penumbra.
