![]() "It's a real testament to the care and the precision with which the observatory was put together on the ground and with how smoothly the ride to space went and all those deployments," says Perrin. Marshall Perrin, Webb deputy telescope scientist at the Space Telescope Science Institute, says that the mirrors' separate depictions of a single star showed up pretty close together in images taken with the camera, suggesting that the mirrors are already aligned reasonably well. It will also allow astronomers to probe the composition of the atmospheres of planets that orbit other stars, searching for combinations of gases that might indicate the possible presence of life. ![]() Once it is fully operational, this telescope should be able to capture faint infrared light that has been traveling through space for almost the entire history of the universe, revealing what the first galaxies looked like after the Big Bang. Science Why some astronomers once feared NASA's James Webb Space Telescope would never launch He thinks they won't know for sure that everything is OK until some fine-tuning that should occur in March. But Feinberg cautions that there's still plenty of work ahead. So far there's no sign of any major flaw, like the one that troubled the Hubble Space Telescope before astronauts went up and fixed it. "It is still early, but we are very encouraged with what we are seeing." "This amazing telescope has not only spread its wings, but it has now opened its eyes," says Lee Feinberg, Webb's optical telescope element manager at NASA's Goddard Space Flight Center in Greenbelt, Md., who adds that all the initial results match their simulations and expectations. Images like these are incredibly important as mission managers start to carefully adjust the position of each mirror segment to get them working as one giant mirror that's 21 feet across. "Wing" refers to the two sides of the mirror assembly that unfolded in space. Each is labeled with the name of the mirror segment that captured it. For the cases of Planet Nine and any other trans-Plutonian planet, the strong gravitational lensing is impossible because at least one of the images is always eclipsed.This mosaic shows images of the same star. The possibility of resolving these images is one of the main arguments favouring the gravitational lensing method as its efficiency in searching for dark massive objects at the edge of the Solar System is higher than the one corresponding to other methods such as stellar occultation. It is demonstrated that in most cases of the close rapprochement of a source and the lens (for Nemesis and Tyche), it is possible to resolve two images. The formation of gravitational lensing images is studied here for a point mass event. It is shown that, the required value of the scattering angle can be measured for the cases of Nemesis and Tyche. The problem of the definition of a scattering angle of a photon in the gravitational field of a spherical lens is studied. Basic physical properties and orbital characteristics of such massive bodies are considered. ![]() In this paper, the hypothesis of the existence of a massive dark body (Nemesis, Tyche, Planet Nine, or any other trans-Plutonian planet) at the Solar system periphery is analysed.
