Explore mundos misteriosos em The Hunt for Planet B

Just a thought could send you down an existential rabbit hole. But I love looking at the universe and thinking about all the possibilities waiting to be explored.

Astronomers have not yet found a solar system like ours. Of the thousands of known exoplanets, none quite compare to the ones in the cosmic backyard. But scientists are just beginning to scratch the surface of these planets outside the solar system. The next step is to look inside.

If you’ve been fascinated by exploring other worlds, check out “The Hunt for Planet B,” which airs on CNN on Saturday, November 20 at 9:00 PM EST.

Follow scientists as they plan to launch NASA’s James Webb Space Telescope, the world’s most powerful space observatory.

defying gravity

After years of delays, the Webb telescope is scheduled to launch on December 18 in French Guiana. He will study exoplanets in new ways and See the universe deeper than ever.

NS The name of the telescope is controversialMany still hope that NASA will change that.

Webb will examine the atmospheres of exoplanets, some of which are likely habitable. For those who have submitted questions about the mission, we’ve done it. Tracking expert responses.

Webb is ready to help us understand the origins of the universe and begin answering key questions about our existence, such as where we come from and whether we are alone in the universe.

other worlds

Oh, the places Webb will go! The telescope will look at different things, such as stars and galaxies in the distant universe and planets in our solar system, but many people associate Webb with exoplanets.

Once launched, the telescope will undergo months of preparation to make observations within a million miles of Earth. Then, The magic begins.

The observatory will examine the TRAPPIST-1 system, which includes seven Earth-sized exoplanets orbiting a cold dwarf star about 40 light-years away.

But astronomers are also interested in investigating other mysterious exoplanets, such as those between the sizes of Earth and Neptune. There is no known planet like this found in our solar system – but it is the most common exoplanet in our galaxy. Scientists now want to know how they formed.

around the universe

Scientists agree that for humanity there is likely to be no Planet B, we must do everything in our power to take care of the Earth, because they say it is. The only world for us.

But looking into the future, it’s a question that baffles astronomers: If Planet B existed, what would it look like?

Some believe that it will be a true twin of the Earth, since life is formed in the same way that it is formed here.

Others expect us to learn that life can be shaped in many ways. When looking at the diversity of exoplanets around different types of stars, this does not seem unlikely.

So here’s a more interesting idea: What if life did not begin on Earth?but somewhere else?

If you’ve been working from home during the pandemic, your pet has probably gotten used to having fun — which makes separation anxiety even more challenging when you’re back in the office.

Elena Herskij Douglas, professor of animal-computer interaction at the University of Glasgow, Scotland, decided to change that with her DogPhone. Unlike other pet technologies, DogPhone allows dogs to call their owners.

She tested her invention on Zack, her black Labrador retriever, hiding a sensor inside a ball. If the ball is moved, it will start a video call on the computer. NS The results are promising.

ocean secrets

It’s time to go to the twilight zone – the ones in the ocean. This region, before daylight gives way to the permanent darkness of the deep sea, is as mysterious to us as space.

The more researchers learn, the more they realize that the animals that live in them play an important role in regulating the Earth’s climate. Here, beautiful and exotic creatures migrate up and down daily.

This region has a surprising backer: director James Cameron.

“It acts like a giant carbon bomb that pulls carbon out of the atmosphere and transports it to the depths of the ocean,” Cameron told CNN. Just One of the reasons he wanted to preserve this area, the largest biomass on our planet.
