Explore the mysterious worlds in the Hunt for Planet B

One thought can send you down an existential rabbit hole. But I like to look at the Universe and think about all the possibilities that are waiting to be discovered.

Astronomers have yet to find a solar system similar to ours. Of the thousands of known exoplanets, none can match the planets in the backyard of space. But scientists are just beginning to explore the surface of these planets outside the solar system. The next step is to look inside.

If you’re keen on exploring other worlds, watch The Hunt for Planet B, which airs on CNN on Saturday, November 20 at 9:00 pm ET.

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

O The name of the telescope is controversialand many still hope NASA will change that.

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

other worlds

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

After launch, the telescope will take months to prepare for observations a million miles from Earth. Later, the magic begins

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

But astronomers are also interested in exploring other mysterious exoplanets, such as planets the size between Earth and Neptune. Our solar system does not have a planet as famous as this, but it is the most common exoplanet in our galaxy. Now scientists want to know how they formed.

across the universe

Scientists agree that there will likely not be a planet B for humanity. We must do our best to take care of the Earth because they say it is. The only world for us.

But looking ahead, astronomers are bewildered by the question: if planet B existed, what would it look like?

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

Others expect us to learn that life can be shaped in different ways. If you look at the variety of exoplanets around different types of stars, it doesn’t seem so incredible.

So, there is a more interesting idea: What if life on Earth never started?, and somewhere else?

Wonderful creatures

If you worked from home during the pandemic, your pet is probably used to having fun, which complicates separation anxiety when you return to the office.

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

She tested her invention on Zach, her black Labrador retriever, by hiding a sensor inside a ball. If the ball moves, it initiates a video call on the computer. O The results are promising

Spotify launches two custom home channels for music and podcasts

For music lovers and listeners of good podcasts, o Spotify llaunched another novelty to facilitate and make the user experience more exciting. The idea is to offer a new home screen, the streaming service home screen, for profiles and split it into two feeds, one dedicated to news and the other song suggestions and others for new episodes and podcast trends.

Android devices will be unveiled before iOS, which still doesn’t have a news release date.

The new home will work to bring even more offers to help profiles find the content they’re looking for. Currently, issues related to the world of music and audio programs The most diverse themes are combined in the house, classified together between the latest reproductions and the profile’s favorite and most listened to products.

There are proposals for alternating user themes such as “Your music misses you”, “Looks like such an artist”, “Popular with listeners of such a podcast show”, but in the announced split, the two products are treated as different paths for the user to consume and facilitate navigation .

Thus, the tape dedicated to song there will be the usual suggestions for new songs and artists based on what has been heard previously, as well as mixes and playlists, as well as link exchanges and instant track playback.

With the Podcast & Shows channel, you’ll get faster access to new episodes of your favorite audio shows and more accurate product recommendations. It will also be possible to read the description of each episode, save it as a favorite or listen later and play the new show without leaving the page in the midst of so much content.

Google pushes Apple for new RCS messaging campaign

Google pushes Apple for new RCS messaging campaign

O Google launched another advertising campaign to put pressure on Apple Adopt the RCS standard for instant messaging. “Get The Message” is a short video demonstrating the wide availability of the messaging format across a wide variety of brands using Android and highlighting Apple’s neglect.

The images provide a very simple explanation of what RCS is and how the protocol can improve online chat. The structure of the format allows you to send multimedia messages, check the status of reading and much more, creating competition for services such as whatsapp e Telegram.

 

Campaign not the reference to distinguishing the colors of the balloons goes unnoticed, obviously. Text field colors sparked controversy a few months ago when the Wall Street Journal reported on the complex stigmatization of “green balls,” the palette used by iOS to represent messages received in the SMS standard (usually sent from Android devices). . . .

“Apple just needs to think differently,” says the commercial, referring to Apple’s old “Think Different” slogan.

old trick

Within a few months Google tries to convince Apple accept the RCS protocol as one of the formats accepted by iMessage, the default messaging app for iPhone. Adding a format would actually facilitate communication between users of different platforms, but the debate goes deeper.

O The RCS format started slowly and suffered greatly from dependence on telephone operators. – something that in some way created a certain prejudice against technology. It was difficult to know when this standard was used for messaging, how much it cost, and what its benefits were. The situation began to change in 2019, when Google took over the implementation of the protocol.

From there, the reach of RCS has been greatly extended to Android devices. The popularity of the protocol, which simplifies communication, has spurred the adoption of Google Messages, the company’s dedicated SMS and RCS chat application.

However, one final hurdle is missing: Apple. iMessage may not be one of the strongest apps in Brazil (which is dominated by WhatsApp), but its presence in other regions of the world such as the US is very important.

Stuck with Apple

However, this condition of exclusivity creates a vicious circle – and Apple knows it. While iMessage provides simplified communication between Apple consumers, the trend is that they will continue to buy new iPhones. A user trying to get out of this “bubble” can be excluded from most conversations between friends, teachers, colleagues and family, as a Wall Street Journal article found.

So if Apple adopted the RCS standard, iPhone owners would have another opportunity to leave the company’s ecosystem, even if they had to try an Android phone. The move will not generate direct profit for Google, but buying more Android devices will inevitably increase the company’s market share in this segment.

The Earth was hit by the solar wind at a speed of 600 kilometers per second

Ilustração vento solar a atingir a Terra

We really do not live in peacetime. There is talk of extreme droughts, wars, fires, economic crises, and even in space, our star insists on whipping the planet with solar winds that surprise scientists who study these phenomena. The most recent case was a solar storm that hit Earth over the weekend. Without warning, the winds “hit” our planet in a completely unexpected way.

On Sunday, a stream of solar wind hit the Earth’s magnetic field, the speed of which reached more than 600 kilometers per second.

As we already mentioned, our star is in its 25th cycle, and when it began, the researchers left an alert that this new 11-year period will not be as calm as the last one, which ended at the end of 2019.

Some events, such as the M4.4 class solar flare or the X-class flare that occurred in 2021, show ongoing activity on our star. By the way, we saw that a G1 class storm was predicted last week. According to NOAA, this event, which reached us on August 3, did not cause any problems and its origin was associated with a hole in the sun. as explained here.

The Earth received an unexpected impact at a speed of more than 600 kilometers per second

Without warning, a strong gust of solar wind hit Earth last Sunday. While it's not all that alarming - solar storms often hit our planet and cause spectacular auroras - it's strange that this storm was completely unexpected.

This event was not in the forecast, so the auroras that arose came as a surprise.

informed SpaceWeather.

The solar wind occurs when a stream of high-energy particles and plasma can no longer be held by the Sun's gravity and erupts towards the Earth. Because how our Sun works is still largely unknown, these emissions are thought to come from large, bright spots on the Sun known as "corona holes." These events taking place on a star have been observed for a long time, and there is a lot of observational work being done here on Earth.

Picture of two holes in the sun

Through this attention to holes, scientists have been able to create "predictions" of space weather. They can already predict when these solar storms or solar flares, also known as coronal mass ejections (CMEs), will come our way. Plus, you can already see how powerful they will be.

However, this does not mean that the Sun does not surprise us and hit us without warning, as it did over the weekend.

But how was this effect of solar winds on our planet discovered?

Earlier Sunday, NASA's Deep Space Climate Observatory (DSCOVR) observed solar wind light streams that increased significantly and unexpectedly throughout the day. The cause of this solar storm is still unknown, but SpaceWeather suggests it may have been an early arrival of the solar wind, which is expected to come from an equatorial hole in the Sun's atmosphere two days later. Or it could be a lost coronal mass ejection (CME).

The inhomogeneity of the solar wind data at 00:45 UT on August 7 suggests a shock wave embedded in the solar wind.

Today, the active sun produces so many small explosions that it is easy to ignore the faint coronal ejections heading towards Earth.

This is how he described the SpaceWeather service.

It is interesting to note that as of today, August 9, the high-speed solar wind continues to beat the Earth's magnetic field, with records showing speeds as high as 551.3 kilometers per second. This new "attack" on our natural shield began this morning at 5 am.

The good news is that the solar wind is not harmful to us here on Earth. This is because we are safely protected by our planet's atmosphere.

However, when the "collision" is strong, our technologies can suffer from it. That's why they talk about it and we've seen it before problems with telecommunications satellites and, in extreme cases, with electrical networks.

Solar storm classified as G2

These winds have been classified as a moderate G2 solar storm - storms are classified as G1 at the bottom of the scale to G5 which is a powerful solar storm.

According to space meteorology, G2 storms can affect high-latitude energy systems and could impact spacecraft orbit forecasts.

In fact, it is already becoming a routine. This is due to the fact that this year there are especially many such events. However, as mentioned above, these 11 years of the 25th solar cycle will not be peaceful.
