Eyes in the sky Several space telescopes planned for Launch after the James Webb Space Telescope(JWST)promise to deliver incredible science. Here are three of the most important. | ||
Planetary Transits and Oscillations of stars (PLATO) Expected launch date: 2026 This European Space Agency project will search a million stars looking for blips in their light that indicate the presence of an orbiting planet. Similar kinds of previous telescopes have only been able to see planets that are close to their stars and so pass in front of them frequently. Plato will linger on each star for longer and so has the chance to detect planets that are more distant from their star, with a longer orbital period. In particular, the mission is focused on trying to spot signs of rocky exoplanets in the habitable zone, the narrow region of a star system in which temperatures are right for liquid water. It also has the tools to characterize such worlds, providing clues to how Earth-like they may be. | Nancy Grace Roman Space Telescope Expected launch date: 2025 Like the James Webb Space Telescope, the Roman Space Telescope, named after the first female executive at NASA, will observe mainly infrared radiation. But while the JWST focuses on detail, Roman is going for the big picture. The telescope has a panoramic(全景的)field of view more than 100 times greater than the JWST’s. During its first five years, Roman will image more than 50 times as much sky as the Hubble Space Telescope covered in its first 30 years. That will allow it to make the first wide-field infrared maps of the sky. It is hoped this will help solve mysteries like the true identity of dark matter and dark energy. Astronomers can see the influence of these substances on the universe but have not been able to explain what they are. | Laser Interferometer Space Antenna(LISA) Expected launch date: 2034 We first detected gravitational waves, ripples in the fabric of space, in 2015. So far, we have seen waves from black hole and neutron star collisions(碰撞). LISA, a mission led by the European Space Agency, will be a much larger gravitational wave detector than existing ground-based ones. It will consist of three spacecraft positioned 2.5 million kilometres apart in a triangular formation. This space detector will be sensitive to gravitational waves with extremely low frequencies. Among other things, it could allow us to spot planets in other galaxies just from the subtle way in which they influence the gravitational waves produced by their parent stars. Until now, all confirmed discoveries of exoplanets have been in our own Milky Way galaxy. |
A.It is designed to detect gravitational waves in the fabric of space. |
B.It is aimed to look for planets that are closely orbiting their stars. |
C.It is the first of its kind to be able to see blips in the stars’ light. |
D.It observes each star for longer so as to detect more distant planets. |
A.The Roman Space Telescope can observe infrared radiation while the JWST cannot. |
B.The Roman Space Telescope has a larger field of view compared to the JWST. |
C.The James Webb Space Telescope make the first wide-field infrared maps of the sky. |
D.The James Webb Space Telescope can image more than 50 times as much sky as the Roman. |
A.All of the three space telescopes are being led by the European Space Agency. |
B.With the help of LISA, we might be able to find planets outside of the Milky Way galaxy. |
C.Getting wide-field infrared maps of the sky, scientists are sure to spot what dark matter and dark energy are. |
D.Scientists have already confirmed the clues to the existence of all the exoplanets with the aid of gravitational waves. |
2 . While some say school safety depends on guns, cameras or alarms in classrooms, Mark Gomer and Kristi Schiller think specially trained dogs should play an important role in preventing violence in schools.
Gomer’s for-profit company has sent a gun-and-drug detecting dog to patrol (巡查) the halls of an Ohio high school, while Schiller is launching a nonprofit program in Houston to give schools the trained dogs for free.
Gomer’s first full-time safety dog is a three-year-old Dutch shepherd named Atticus, who is reported to duty this school year at Oak Hills High School in Green Township in southwest Ohio. The dog was trained at the school before the summer break, said Gomer, co-owner of American Success Dog Training in Bridgetown, Ohio. Atticus has won over students, parents, teachers and district Superintendent Todd Yohey, who initially worried what people would think of him spending $10,000 on a dog. Gomer has talked to a lot of parents and faculty, and they are saying it was money well-spent, he said.
For her part Schiller is looking to provide safety dogs to schools free of charge. She hopes her new initiative, program “K9S4KIDS”, does for schools what her program “K9S4COPS” did for police departments. She has placed more than 60 dogs with agencies in three years. “These dogs are extremely social, yet highly qualified warriors that are accustomed to going straight to the source of a threat or shooter and disengaging the suspect armed with the weapon,” said Schiller.
As the programs get up and running, questions remain about possible health problems and distractions the dogs can cause.
A school safety expert said those are concerns parents and schools will have to work out. Ken Trump, president of the Cleveland-based National School Safety and Security Services consulting firm, discussed the issue in general because he was not familiar with either program.
He said the dogs would have to be extremely social to deal with students’ initial excitement “Kids are going to like those dogs,” Trump said, “There are concerns to work around, but with the right dogs and right handler and the right policies and procedures, they should be very beneficial. The dog might be a distraction in the beginning, but they will become part of what students expect to see when they go to school.” “There is so much these dogs can do,” said Ted Dahlin, a deputy who serves on the K9S4COPS board of directors. “If I were going to pick a school to make trouble, it would be one that I knew didn’t have a dog.”

10 . He’s considered the father of the technological innovation, and apart from that, he was also known as a design perfectionist. There is no single executive or creator in the technology industry who is more creative and inspirational than him, and with that being said he was a one-in-billion creator.
On February 24, 1955, in San Francisco, California, United States, a baby named Steve Jobs entered the world. His parents’ inability to provide for him led to a difficult childhood, one in which he battled with his sense of self and felt constantly confused and unfulfilled. Nonetheless, who could have predicted that this person would cause such a dramatic shift in the information technology? The way Steve Jobs showed the world the new products and devices he was working on was truly out of this world, and that’s a big part of why he’s so beloved.
Steve Jobs was well-informed, but he was not a scholar. He possessed a high IQ but showed little enthusiasm for formal education. His main hobbies were playing tricks on people via phone and computer, goofing off with his best friends, and coming up with ground-breaking business concepts.
Steve Jobs’ philosophy on education is well-known at this point; he has stated publicly that he was only able to learn after leaving college. When Steve Jobs and his friend Wozniak were in their early 20s, they came up with the idea for the Apple Computer. Steve Jobs’ Volkswagen bus and Wozniak’s beloved scientific calculator were sold to finance the pair’s garage-based startup. Jobs and Wozniak have been given much of credit for democratizing the computer industry by making computers more user-friendly, portable, and affordable.
Wozniak envisioned a line of accessible and lightning-fast personal computers, and Jobs was put in charge of the company’s marketing and management. From the get-go, Apple sold the computers for up to $666. The unexpected greatness of their early success inspired them to develop more powerful machines. In the 70s, they accomplished what would become the company’s crowning achievement. Assembled by Apple, Inc. , the high-performance computer was an instant success in their home state of California, and its sales helped make Jobs a multimillionaire.
