The Center of Curvature Optical Assembly (COCOA) tool will be used on the NASA James Webb Space Telescope (JWST) this winter, when engineers building the massive space observatory will test to see whether its mirrors are perfectly shaped and aligned or not.
Having a correct mirror alignment tends to be rather impor... |

When the NASA Hubble Space Telescope will be retired from active duty, the James Webb Space Telescope should theoretically be put in its place. This is the most advanced, largest orbital observatory ever designed, and is currently under construction.
The tool will have a massive main mirror, several times la... |

The NASA James Webb Space Telescope (JWST) is already helping to improve the world. Though its advanced technology is created to observe the early Universe, experts have already found a way to apply it to the field of ophthalmology, or eye health.
If completed, this telescope will be the American space agency... |

Earlier this week, the NASA James Webb Space Telescope (JWST) program achieved an important milestone, when the first batch of segments that will go on to form the spacecraft's main mirror managed to successfully pass cryogenic tests.
The assessments were designed in such a way that they mimicked the conditi... |

The first experimental evidence that the Casimir effect actually exists were obtained by researchers from the Chalmers University in Sweden. Using a rapidly-moving mirror, virtual photons were turned into real ones, the team reports. The dynamical Casimir effect manages to confirm one of the most interesting and surp... |

The effort to construct the massive James Webb Space Telescope (JWST) has reached a critical mission milestone on April 6. Engineers managed to complete the construction of a giant structural steel frame, that will act as a stand for the components of the flight optics system. What the huge assembly will do is it wil... |

Ever since scientists learned that the eyes of bees allowed the insect to execute remarkable feats of flight and reconnaissance, they wanted to be able to replicate the ability. Even though the flying insects have very tiny brains, they are able to make complex decisions based solely on their vision. They have many e... |

As the Hubble Space Telescope is reaching the end of its life, experts at the American space agency are currently racing against the clock to develop the next generation of space observatories. Their solution to replacing the venerable orbital instrument is the James Webb Space Telescope (JWST). The planned machine, ... |

Cichlid fish males are not exactly cowards. They are very territorial and highly aggressive, and would gladly pick a fight with any other fish that happens to enter their waters. They are also known for the fact that they readily attack their own reflections, posturing and lunging as in a real battle. But scientists ... |

Using data collected by a NASA spacecraft, experts were finally able to rediscover a long-lost, Soviet-built reflecting device on the surface of the Moon. The exact location of the scientific payload has remained a mystery since September 14, 1971. At that date, the Soviet Union lost contact with its Lunokhod 1 rover... |

When scientists at the US Department of Energy's (DOE) Lawrence Livermore National Laboratory (LLNL) first designed advanced mirrors, they had a specific use in mind, producing better, faster and smaller computer chips. The effort to create these instruments included at one point nearly 200 scientists, as well a... |

Even though the famous Hubble Space Telescope was repaired and upgraded in May 2009, it is clear that the technology on it cannot help the machine keep its dominant position for much longer. NASA is already working on a replacement for it, the massive James Webb Space Telescope, which will truly be a sight to behold ... |

Astronauts that flew to the Moon via the Apollo program left behind a host of scientific experiments on the lunar surface, including a few sets of mirrors. These instruments were designed in such a manner that a laser beam shone from Earth would be reflected back. This enabled physicists to conduct various types of s... |

Polymers, or electrically conducting plastics, were discovered more than ten years ago to be able to generate what researchers referred to as random lasers. This was a very peculiar phenomenon, which some physicists even refused to believe existed. Now, all these years later, scientists at the University of Utah, whe... |

A new scientific study evidenced the fact that the average farm pig could learn to find food with the help of mirror reflections in less than five hours. As this ability pigs had had been proven, experts added it to the small number of species who could recognize themselves in the mirror, which included dolphins, som... |

Mathematician Andrew Hicks from the Drexel University managed to develop, in collaboration with colleague Ron Perline, a new type of rear-view mirror, one that offers a wide-angle view of what's behind the car, while at the same time eliminating the dreaded blind spot that each car has. This spot is located on a... |
