Explore mysterious worlds in “The Hunt for Planet B”


The mere thought can send you down an existential rabbit hole. But I like to look at the universe and consider all the possibilities that are begging to be discovered.

Astronomers have yet to find a solar system similar to ours. And among the thousands of known exoplanets, none quite match the planets in our cosmic backyard. But scientists have only just started scratching the surface of these planets outside the solar system. The next step is to look inside them.

The name of the telescope is not without controversy, and many still hope NASA will change it.
Webb will scan the very atmospheres of exoplanets, some of which are potentially habitable. For those of you who have asked questions about the mission, we have sought answers from the experts.

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

Other worlds

Oh, the places Webb will go! The telescope will examine a variety of objects, like stars and galaxies in the distant universe and planets in our own solar system, but many associate Webb with exoplanets.

Once launched, the telescope will undergo months of setup to prepare for taking observations a million miles from Earth. Then the magic begins.

The observatory is expected to 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 eager to study other mysterious exoplanets, like those between the sizes of Earth and Neptune. No known planet like this exists in our solar system, but it is the most common exoplanet in our galaxy. Now scientists want to know how they were formed.

Across the universe

Scientists agree that for humanity there is probably no planet B. We have to do everything we can to take care of the Earth because they say it is the only world for us.

But for the future, this is a question that astronomers are asking: if planet B exists, what could it look like?

Some believe it will be a true terrestrial twin where life is formed in much the same way as here.

Others hope that we will learn that life can be formed in various ways. When you look at the diversity of exoplanets around different types of stars, it doesn’t seem that far-fetched.

And then there’s an even more intriguing idea: what if life doesn’t start on Earth at all, but elsewhere?

Fantastic creatures

If you’ve been working from home during the pandemic, chances are your pet has gotten used to the extra quality time – making separation anxiety all the more difficult once you’re back home. office.

Ilyena Hirskyj-Douglas, lecturer in animal-computer interaction at the University of Glasgow in Scotland, decided to change that with the DogPhone. Unlike other pet technology, DogPhone allows dogs to call their owners.

She tested her invention on Zach, her black Labrador, by hiding a sensor inside a bullet. If the ball is moved, it triggers a computer video call. The results are promising.

Secrets of the ocean

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

The more researchers learn, the more they realize that the animals that inhabit it play a vital role in regulating the Earth’s climate. Here, beautiful and strange creatures migrate from top to bottom on a daily basis.

This area has a surprising defender: filmmaker James Cameron.

“It acts like this giant carbon pump that extracts carbon from the atmosphere and brings it to the depths of the ocean,” Cameron told CNN. This is just one of the many reasons he wants to preserve this region, the largest biomass on our planet.


Take another look:

– Litter floating in space is a growing problem, and this week it’s only gotten worse, sending the space station crew scrambling for safety.
– More than 1,000 manatees in Florida have died this year, the highest number in decades, and the reasons may surprise you.
– Archaeologists have discovered what they believe to be one of Egypt’s lost “sun temples”, dating from the mid-25th century BCE.
