Description | The image is a false-colour image reproduction from a short-exposure CCD frame, obtained with the Danish 1.54-metre telescope and the DFOSC instrument with a 2052 x 2052 pix Loral/Lesser CCD. They show the innermost coma of Comet Hyakutake and the pronounced asymmetry of the dust distribution around the nucleus. This photo displays an area of approx. 9.2 x 6.7 arcmin. The typical elongation in the anti-solar direction (at p.a. = 290 deg, i.e. West-North-West) is very pronounced. The asymmetry in the upper-right quadrant (North-West) is also obvious. When moving outwards from the nucleus (located within the black area), the isophotes (curves of equal brightness; particularly well shown by the contrasting colours on these photos) turn anti-clockwise over an angle of about 20 degrees. This effect is caused by the repulsive action on the dust grains by the solar photons. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
