Galaxies, made up of billions of stars like our Sun, are the beacons that light up the structure of even the most distant regions in space. Not all galaxies are alike, however. They come in very different shapes and have very different properties; they may be large or small, old or young, red or blue, regular or confused, luminous or faint, dusty or gas-poor, rotating or static, round or disky, and they live either in splendid isolation or in clusters. In other words, the universe contains a very colourful and diverse zoo of galaxies. For almost a century, astronomers have been discussing how galaxies should be classified and how they relate to each other in an attempt to attack the big question of how galaxies form. Galaxy Zoo (Lintott et al. 2008, 2011) pioneered a novel method for performing large-scale visual classifications of survey datasets. This webpage allows anyone to download the resulting GZ classifications of galaxies in the project.
The World Ocean Atlas (WOA) contains objectively analyzed climatological fields of in situ temperature, salinity, oxygen, and other measured variables at standard depth levels for various compositing periods for the world ocean. Regional climatologies were created from the Atlas, providing a set of high resolution mean fields for temperature and salinity. The World Ocean Atlas 2018 (WOA18) release September 30, 2018 updates previous versions of the World Ocean Atlas to include approximately 3 million new oceanographic casts added to the World Ocean Database (WOD) and renewed and updated quality control. The WOA18 temperature and salinity fields are being released as preliminary in order to take advantage of community-wide quality assurance. WOA follows the World Ocean Database - WOD periodic major releases and quarterly updates to those releases.

The HEASARC is a multi-mission astronomy archive for the EUV, X-ray, and Gamma ray wave bands. Because EUV, X and Gamma rays cannot reach the Earth's surface it is necessary to place the telescopes and sensors on spacecraft. The HEASARC now holds the data from 25 observatories covering over 30 years of X-ray, extreme-ultraviolet and gamma-ray astronomy. Data and software from many of the older missions were restored by the HEASARC staff. Examples of these archived missions include ASCA, BeppoSAX, Chandra, Compton GRO, HEAO 1, Einstein Observatory (HEAO 2), EUVE, EXOSAT, HETE-2, INTEGRAL, ROSAT, Rossi XTE, Suzaku, Swift, and XMM-Newton.
Our knowledge of the many life-forms on Earth - of animals, plants, fungi, protists and bacteria - is scattered around the world in books, journals, databases, websites, specimen collections, and in the minds of people everywhere. Imagine what it would mean if this information could be gathered together and made available to everyone – anywhere – at a moment’s notice. This dream is becoming a reality through the Encyclopedia of Life.

The GISAID Initiative promotes the international sharing of all influenza virus sequences, related clinical and epidemiological data associated with human viruses, and geographical as well as species-specific data associated with avian and other animal viruses, to help researchers understand how the viruses evolve, spread and potentially become pandemics. *** GISAID does so by overcoming disincentives/hurdles or restrictions, which discourage or prevented sharing of influenza data prior to formal publication. *** The Initiative ensures that open access to data in GISAID is provided free-of-charge and to everyone, provided individuals identify themselves and agree to uphold the GISAID sharing mechanism governed through its Database Access Agreement. GISAID calls on all users to agree to the basic premise of upholding scientific etiquette, by acknowledging the originating laboratories providing the specimen and the submitting laboratories who generate the sequence data, ensuring fair exploitation of results derived from the data, and that all users agree that no restrictions shall be attached to data submitted to GISAID, to promote collaboration among researchers on the basis of open sharing of data and respect for all rights and interests.

BCSDB database is aimed at provision of structural, bibliographic, taxonomic and related information on bacterial carbohydrate structures. Two key points of this service are: covering - is above 90% in the scope of bacterial carbohydrates. This means the negative search answer remains valuable scientific information. And consistence - we manually check the data, and aim at hight quality error-free content. The main source of data is a retrospective literature analysis. About 25% of data were imported from CCSD (Carbbank, ceased in 1997, University of Georgia, Athens; structures published before 1995) with subsequent manual curation and approval. Current coverage is displayed in red on the top of the left menu. The time lag between publication of new data and their deposition ~ 1 year. The scope is "bacterial carbohydrates" and covers nearly all structures of this class published up to 2016. Bacterial means that a structure has been found in bacteria or obtained by modification of those found in bacteria. Carohydrate means a structure composed of any residues linked by glycosidic, ester, amidic, ketal, phospho- or sulpho-diester bonds, in which at least one residue is a sugar or its derivative.
