Australian scientists found a detached coral reef on the Great Barrier Reef that exceeds the height of the Empire State Building and the Eiffel Tower, the Schmidt Ocean Institute said this week, the first such discovery in over 100 years.
The “blade like” reef is nearly 500 metres tall and 1.5 kilometres wide, said the institute founded by ex-Google boss Eric Schmidt and his wife, Wendy. That’s nearly as tall as the CN Tower, whose antenna reaches a height of 553 metres.
On October 20th, scientists with the <a href=”https://twitter.com/hashtag/EdgeGBR?src=hash&ref_src=twsrc%5Etfw”>#EdgeGBR</a> expedition uncovered a new detached reef to be added to the <a href=”https://twitter.com/hashtag/GreatBarrierReef?src=hash&ref_src=twsrc%5Etfw”>#GreatBarrierReef</a>.

The reef lies 40 metres below the ocean surface and about six kilometres from the edge of Great Barrier Reef.
A team of scientists from James Cook University, led by Robin Beaman, were mapping the northern sea floor of the Great Barrier Reef on board the institute’s research vessel Falkor, when they found the reef on Oct. 20. “We are surprised and elated by what we have found,” said Beaman.
He said it was the first detached reef of that size to be discovered in over 120 years and that it was thriving with a “blizzard of fish” in a healthy ecosystem.
The discovery comes after a study earlier this month found the Great Barrier Reef had lost more than half its coral in the last three decades.
Reef explored by robot
Using the underwater robot known as SuBastian, the scientists filmed their exploration of the new reef, collecting marine samples on the way, which will be archived and placed in the Queensland Museum and the Museum of Tropical Queensland.
“To not only 3D map the reef in detail, but also visually see this discovery with SuBastian is incredible,” Beaman added.
Although the northern section of the Great Barrier Reef suffered from bleaching in 2016, Beaman said this detached reef didn’t display any evidence of damage.
Bleaching occurs when the water is too warm, forcing coral to expel living algae and causing it to calcify and turn white.

The Great Barrier Reef runs 2,300 km (1,429 miles) down Australia’s northeast coast spanning an area half the size of Texas. It was world heritage listed in 1981 by UNESCO as the most extensive and spectacular coral reef ecosystem on the planet.

A 'Beaver Full Moon' With Lunar Eclipse Happened This Morning—And Folks Took Some Stunning Photos – Good News Network
If you were up in the early hours of this morning, you may have noticed the full moon turning a shade or so darker and redder.
What you were seeing is called a penumbral lunar eclipse. Caused by the moon dipping behind the Earth’s fuzzy penumbra, or outer shadow, this subtle shading effect peaked at 4:32 am ET November 30, when—according to NASA—83% of the moon was in the shadow of our planet.
NASA has also given a list of the names November’s full moon is known by: The Algonquin tribes have long called this the Cold Moon after the long, frozen nights. Others know it as the Frost Moon, while an Old European Name is Oak Moon: perhaps because of ancient Druid traditions that involve harvesting mistletoe from oak trees for the upcoming winter solstice.
In America, the November full moon is perhaps still best known as the Beaver Moon—with Native Americans associating it with a time when the beavers are scrabbling to finish building their dens from mud and sticks and rocks in preparation for winter.
While this was the last penumbral eclipse of the year, don’t worry if you missed the occurrence due to sleep or clouds.
For those who didn’t get to witness the phenomenon in person, from San Francisco to Michigan to the Sydney Opera House, here are some stunning pictures of this year’s last partial lunar eclipse.
P.S. The next full moon will be the Cold Christmas Moon on December 29, 2020.

How to see a mysterious object that might be space junk fly near Earth today – CNET
The moon shouldn’t feel too jealous. Earth has another satellite right now, but it’s only a temporary fling. The exact identity of the object, named 2020 SO, is still a lingering question, but you can watch it on Monday, Nov. 30, when it gets close to Earth. The Virtual Telescope Project will livestream the flyby.
The Earth’s gravitational pull captured the object into our planet’s orbit earlier this month, which makes 2020 SO a sort of mini-moon.
Usually, we’d, and there are plenty of those flying around in space. But 2020 SO may have a more Earthly identity. The orbit of 2020 SO around the sun — which is very similar to Earth’s — has convinced researchers it’s probably not a rock, from a NASA mission.
The object’s closest approach to our planet will be on Dec. 1. The Virtual Telescope Project will offer a livestream starting at 2 p.m. PT on Nov. 30.
Virtual Telescope Project founder Gianluca Masi already managed to capture a view of the tiny object on Nov. 22. It appears as a dot against a backdrop of stars.
Scientists with NASA JPL’s Center for Near-Earth Object Studies (CNEOS) analyzed 2020 SO’s path and tracked it back in time.
“One of the possible paths for 2020 SO brought the object very close to Earth and the Moon in late September 1966,” CNEOS Director Paul Chodas said in a NASA statement earlier in November. “It was like a eureka moment when a quick check of launch dates for lunar missions showed a match with the Surveyor 2 mission.”
NASA’s ill-fated Surveyor 2 lander ended up crashing on the moon’s surface, but the Centaur rocket booster escaped into space.
NASA expects 2020 SO to stick around in an Earth orbit until March 2021 when it will wander off into a new orbit around the sun. The agency’s Planetary Defense Coordination Office shared a visual of the object’s journey around Earth.
The upcoming close approach should give astronomers a chance to dial in 2020 SO’s composition and tell us if it is indeed a relic from the 1960s.
Even with a telescope view, 2020 SO should look like a bright spot of light traveling against the dark of space. The cool thing is getting the chance to witness a piece of space history returning to its old stomping grounds.
Climate change has autumn leaves falling sooner, researchers say – CTV News
A new study based on European forest trees indicates that climate change is leading to longer growing seasons and causing leaves to fall earlier in the year.
Using a combination of experiments and long-term observational research dating back to 1948, scientists from the Swiss Federal Institute of Technology and University of Munich found that leaves are likely to fall three to six days sooner by the end of the 21st century, rather than lengthening by one to three weeks as current models have predicted.
Researchers say this predicted pattern will limit the capacity of temperate forests to mitigate climate change through carbon uptake.
In conducting their research, scientists obtained more than 430,000 phenological observations from 3,855 sites across Central Europe from 1948 to 2015.
According to the study, elevated carbon dioxide, temperature and light levels are causing an increase in spring and summer photosynthetic productivity. Leaves are emerging earlier and they’re also falling sooner than expected.
The new findings reveal the critical constraints on future length of growing-seasons and carbon uptake of trees.
Natural Resources Canada says forests can act as either carbon sources or carbon sinks, which means that a forest can either release more carbon than it absorbs or it can absorb more carbon than it releases.
“For decades we’ve assumed that growing seasons are increasing and that the autumn leaf-off is getting later,” co-researcher and professor at ETH Zurich Thomas Crowther told The Guardian. “However, this research suggests that as tree productivity gets higher, the leaves actually fall earlier.”
