天文学家首次拍到黑洞

Astronomers have taken the first ever photograph of a black hole. It is located in a far, distant galaxy called M87, which is 500 million trillion km from Earth.

That gargantuan number is a five followed by twenty zeroes. Scientists estimate the black hole to have a diameter of 40billion km and to be three million times larger than our planet.

》

Lead astronomer Professor Heino Falcke spoke to the BBC about the black hole. He said: What we see is larger than the size of our entire Solar System. It has a mass billion times that of the Sun.

And it is one of the heaviest black holes that we think exists. It is an absolute monster - the heavyweight champion of black holes in the Universe. The image

of the black hole was captured by an array of eight linked telescopes called the Event Horizon Telescope (EHT).

No single telescope exists that is powerful enough to capture the image. Each of the EHT telescopes is located high upon volcanoes in Hawaii and Mexico, mountains in the USA and Spain, a desert in Chile, and in Antarctica.

A team of 200 scientists pointed the networked telescopes towards the M87 galaxy and scanned it over a period of 10days. The data they gathered was stored ·

on hundreds of hard drives.

It was then collated and processed to produce the image that is now a landmark in space exploration. Professor Sheperd Doeleman called it an extraordinary scientific feat.

催熟奶酪的最佳音乐

Scientists have discovered a bizarre link between music and cheese. Different genr es of music affect the way cheese

matures. A top Swiss cheese-maker and a team of

researchers from Switzerland's Bern University conducted a six-month test to look into the effect music had on the maturation process of Emmental cheese. After the cheese had matured, it was sampled and assessed by the researchers and a jury of ,

culinary cheese experts.

The researchers found that cheese that had been played hip-hop had a strong er aroma and flavor than the other cheese aficionados reached the same conclusion as the researchers - the hip-hop cheese was the tastiest.

The experiment involved exposing different cheeses to a 24-hour, non-stop musical loop. A music player directed sound waves at the cheese for six months. The experiment was titled Cheese in Surround Sound.

The music included Mozart's The Magic Flute, Led Zeppelins rock classic Stairway to Heaven, and A Tribe Called Quest's hip-hop tune Jazz (We've Got).

）

A researcher explained the differences in taste.

He said: Bacteria are responsible for the formation of the taste of cheese, wit h

the enzymes that influence its maturity. I

am convinced that humidity, temperature

or nutrients are not the only things that influence taste.

Sounds, ultrasounds or music can also have physical effects.

纸质书更适合做睡前读物

The march of technology may seem unstoppable, but all things digital may

】

have a way to go before they replace the traditional bedtime book - the

paper one.

A new study shows that paper books are better than e-books for bedtime reading.

The study suggests that the good old printed book, with real pages that you tu rn with your fingers, makes parents and children interact more than they do when reading with an electronic book.

Researchers from the University of Michigan studied how 37 pairs of parents and toddlers interacted with e-books and paper books. The researchers found that with electronic books, parents asked their children fewer questions and made fewer

comments about the story.

：

The study involved observing parents and children aged two or three reading from three different book formats. These were printed books, basic e-books on a tablet, and enhanced e-books with features such as animation, graphics and sound effects.

The researchers discovered that the parents and toddlers interacted with each other less with both types of e-books than they did with the printed books. A researcher said that when they did speak, they were far likelier to talk about the

device and the technology rather than about the story.

Children were likelier to say things like, don't push that button or don't chang e the volume than ask questions or make observations about the story.

缓解全球变暖新方法

Scientists have come up with a revolutionary new idea to save planet Earth from global warming. Geo-engineers from Harvard University believe that spraying sun-dimming chemicals into the stratosphere high above the Earth could slowdown global warming.

They also say their technique would be remarkably inexpensive, costing in the region of $ billion a year over a 15-year period. The technique is known as stratospheric aerosol injection (SAI). It is still in its infancy and is yet to be proven.

It would involve the use of gigantic hoses or high-powered chemical cannons …

to spray chemicals into the stratosphere to act as a reflective barrier against sunlight and harmful UV rays.

The scientists have admitted that their idea is currently still in the planning stages. They said: We make no judgment about the desirability of SAI. We simply show that a hypothetical deployment program commencing 15 years hence,while both highly uncertain and ambitious, would indeed be technically possible from an engineering perspective. Not all scientists think the idea is a good one. Some think it is somewhat pie in the sky.

They say it would require a fleet of 100 specially-designed planes to make 4,0 00 missions a year, crossing most of the globe's airspace. This would require

：

permission from over 100 governments. There are also concerns it could increase droughts and extreme weather.
