The Astrophysics programme is dedicated to unraveling the history of the universe.

Athena is scheduled to launch in the early s. The space telescope will answer two big scientific questions: How does ordinary matter glue together to form large-scale structures such as the Milky Way and clusters of galaxies? And how do black holes grow and influence their surroundings? Athena will observe the hot universe for at least four years. Our hardware contribution to X-IFU is the focal plane assembly including its cold electronics. To answer the two big scientific questions mentioned above, Athena will map and study large-scale gas structures in the Universe and survey supermassive black holes and explore high-energy astrophysical events such as supernova explosions and energetic stellar flares.

Communication by and between satellites, including small satellites such as CubeSats, is currently solely relying on radio links in various frequency bands. Most of the small satellites launched until now are involved in technology demonstration missions and only require a small amount of data to be transmitted to ground. This situation is rapidly changing. Recent developments show a strong increase in the use of small satellites for earth observation missions. The huge amount of data gathered by these missions cannot be transmitted to earth in its full amount due to the limited available bandwidth in the radio spectrum. An OGT requires an optical telescope, optical benches, acquisition and tracking mechanism and photonic components such as high power lasers and detectors. The active telescope and beacon lasers are required in the OGT to acquire, track and communicate with satellites as they pass over the OGT. In addition free space optics, detectors and modems are required to convert optical modulated data into the electrical domain and then process in real time the electrical modulated signal into protocols suitable to be relayed via the terrestrial communication backbone. In the reverse direction, terrestrial data is modulated into the optical domain and transmitted to the satellite using high power and accurately pointed laser beams. The key missing part is an integrated ground terminal system that brings these subsystems together. The selling price of a Laser Communication Terminal LCT and its subsystems is a key consideration in making them commercially viable. This TKI aims to end with testing on the ground.

Moreover these insights can be used for other telescope tki such as optical heads for Air and Space terminals, which might be interesting opportunities for Dutch industry as well.

These instruments offer a wide range of capabilities: X-ray imaging, spectrometry, photometry and optical monitoring. The mission enables scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes, exploding stars, to the origin of the universe itself. XMM-Newton was successfully launched on 10 December and is still functioning fine. XMM-Newton operates as an observatory, available to all astronomers. With the help of XMM-Newton — now truly a veteran space telescope — astronomers have made crucial observations that have influenced every aspect of astronomy.

AstroSystems offers the TeleKit in a variety of sizes: 10, What we are really offering is an opportunity for you to experience the pride and satisfaction of building your own, top-quality telescope. It's easy for an individual to spend more attention to detail and more time on fine finishing than commercial suppliers. You can also customize the design and feel confident adding any options desired. We supply all the hard to find or fabricate components, including a light shroud for the trusses and 10" transport wheels and handles. We also supply all the precision cut wood components which are routed with CNC technology. Only the highest quality stainless steel hardware is included.

Few things are as awe-inspiring as being under a clear night sky, looking up, and gazing at a seemingly infinite array of stars overhead. So we rounded up 14 telescopes, and, after months of holding star parties, we think the Celestron NexStar 5SE is the best telescope for a curious amateur. It gathers enough light for you to view the best features of our solar system, and it provides enough power for you to begin exploring deep-sky objects. In addition, this model has an electronic GPS database preloaded with almost 40, celestial objects, so after you calibrate the scope, it can scan the skies for you. This electronic telescope lets you program it to find objects in the night sky automatically, saving you the effort of reading star charts and manuals. This manual telescope a type some people prefer offers quality optics and design touches that far exceed its price. It works best on a tabletop. Though a bit unwieldy at times, this model can view dimmer objects in the deeper reaches of space.

Each grating measures 10 x 20 centimeters. These instruments consist of reflection grating arrays placed behind the telescope mirrors which disperse the light onto CCD detector cameras at the spectroscopic focus of the telescopes. Athena will look for them at distances where the Universe appears to be between 1. Astronomers can use those data to understand how these large-scale structures formed and evolved. Several types of detection techniques are necessary to cover this broad spectral interval. The RGS allows astronomers to decompose X-ray light of individual sources into a spectrum of great detail.

Each RGS has no less than gratings, each made from a 0. Geef een korte toelichting.

Wij zijn benieuwd naar uw mening en gaan graag met u in gesprek. Netherlands Institute for Space Research. Athena will observe the hot universe for at least four years. Science Athena will map the distribution and content of hot gas clouds within galaxies and galaxy clusters at various distances, so at different points in cosmic history. The RGS allows astronomers to decompose X-ray light of individual sources into a spectrum of great detail. But there are more questions that await answers.

An OGT requires an optical telescope, optical benches, acquisition and tracking mechanism and photonic components such as high power lasers and detectors. The Astrophysics programme is dedicated to unraveling the history of the universe. XMM-Newton operates as an observatory, available to all astronomers. X-rays are only reflected at an angle, where the wavelength difference of reflected radiation between two adjacent steps is exactly one entire wavelength or a multiple thereof. These instruments consist of reflection grating arrays placed behind the telescope mirrors which disperse the light onto CCD detector cameras at the spectroscopic focus of the telescopes.
