top 10 science stories of 2017 - top 10 earbuds 2016
On 2017, Did you capture the eclipse, the first video clip of the Ruby Hailong, and news about the first asteroid outside the solar system?
Here's a look back at the most popular scientific stories of the past year on CBC News.
In January, scientists found an animal in the wild that they had never seen before-the Ruby Hailong.
They took some shots of two rare seahorses with a remote underwater camera.
It's like a sea fish swimming on the southern coast of Australia.
Previously, the animal was only found in four specimens of corpses collected since 1919, and was only confirmed as a new species in 2015. 7 Earth-
Like the planets that orbit the stars in February, NASA has announced the discovery of the best places we know so far that life may exist outside the solar system. Seven Earth-
The size of the planet, all of which may contain water, was found to run around a small star
Called TRAPPIST years later-1.
Scientists hope to use the Hubble Space Telescope and the James Webb Space Telescope, which will be launched on 2019, to search for methane, carbon dioxide, oxygen or ozone in the planetary atmosphere, this may indicate whether these planets are truly habitable.
First North American?
In April, scientists said they found evidence that humans were in North America more than 100,000 years earlier than previously thought.
The stone tools and rustodon bones found in California in 1992 were analyzed by uranium dating and found to be from 130,000 years ago.
The finding is controversial, as both ancient biologists and anthropologist agree that humans came to North America about 15,000 years ago.
On June, scientists announced that they had found one that was kept at 99-million-year-
An old amber in Myanmar with scales, feathers and claws.
It even has insects and mites.
Scientists in Canada say the bird, which began in the dinosaur era, had an untimely ending and was wrapped in amber when it was only a few days or weeks old.
The total eclipse of August.
On the 21st, you can see total solar eclipse on the mainland of the United States. S.
This is the first time in 99 years.
The great solar eclipse in the United States has also attracted many Canadians to watch rare astronomical wonders south of the border.
Many people who remain in Canada are still treated for partial solar eclipse.
If you miss the eclipse and only see the partial eclipse and want to experience the whole or see it and want to revisit it, you can check it out here.
You can also start preparing for the next total solar eclipse, which can be seen in some parts of Canada in 2024.
The mysterious signal from space on August.
On the 31st, astronomers looking for signs of intelligent life in the universe announced that they had detected 15 rapid radio bursts from distant galaxies.
These signals are different from the past, prompting a Canadian astronomers to call them "confusing ".
"The researchers hope that the Columbus Bell telescope, which began to operate in September, will help solve the mystery of rapid radio bursts.
In 2017, researchers announced that they had discovered the oldest evidence of life on Earth in Canada.
, An international team of scientists reported that rocks in northern Quebec contain an iron oxide, a tubular structure of which is most likely made by microorganisms.
8 billion years ago.
Then in September, a Japanese
The leading team said they found rocks containing graphite in Labrador that seemed to come from creatures that lived earlier --3.
95 billion years ago.
About four years after the Earth is thought to have formed for half a billion years.
5 billion years ago.
Colliding neutron stars in October, scientists detected gravitational waves from the collision of two neutron stars for the first time, which is an extremely dense relic left by some supernova explosions.
Then, at the other first, they found "kilonova "-a star-
Like the brightness in the sky, it is caused by a combined neutron star and telescope.
There was a lot of amazing things in that collision that produced gold equivalent to Jupiter's mass.
The discovery was announced less than two weeks after three months in the United States. S.
Scientists won the Nobel Prize in Physics for detecting gravitational waves for the first time in 2015.
Later in October, a Canadian astronomers made another unprecedented discovery.
Now at the University of Hawaii Institute of Astronomy, Robert Weryk found an asteroid from outside the solar system.
Something never seen before.
Later, it was called Oumuamua (
Hawaiian language for "Boy Scouts or messengers from a distant past ")
It was later found to be red, Rocky, cigar
About 400-metres long.
CBC quirks and host Bob McDonald of Quarks pointed out that it is similar to the alien spaceship of Arthur C.
Clark's dating novel with Rama.
However, scientists who bugged asteroids failed to detect any alien signals.
In November, more than 15,000 scientists from 184 countries warned humans that saving the planet needed to change.
Climate change, loss of forests, population growth and unsustainable marine fisheries are all contributing to mass extinction, they said.
Their information was widely received by the audience. This is the most
