Proekt Skysoft - internet kollekciya astronomicheskogo programmnogo obespecheniya razlichnogo urovnya ot prostogo professional'nogo i polu professional'nogo do lyubitel'skogo (no poslednego malo). Avtory nadeyutsya, chto ot drugih kollekcii astronomicheskogo softa, sushestvuyushih segodnya v seti, eta budet otlichat'sya professional'noi podderzhkoi i orientaciei ne tol'ko na pol'zovatelei, no i na razrabotchikov. V nastoyashee vremya po adresu http://www.skysoft.org dostupny 197 programm.

Nekotore vremya nazad byla predlozhena koncepciya interaktivnyh astronomicheskih baz dannyh AstroCat. Katalog kataklizmicheskih peremennyh CVcat - pervaya baza dannyh postroennaya po etomu principu.

Predlagaetsya novyi otkrytyi standart hraneniya obshedostupnyh izobrazhenii zvezdnogo neba. Kazhdoe izobrazhenie rassmatrivaetsya kak proekciya uchastka sfery na ploskost', iz takih perekryvayushihsya uchastkov (fasetov) stroyatsya polnye atlasy i krupnomasshtabnye izobrazheniya. Standart orientirovan na massovoe hranenie izobrazhenii i na ispol'zovanie ego v virtual'nyh observatoriyah.

Segodnya na rannei stadii razrabotki nahodyatsya proekty bol'shih nablyudatel'nyh kompleksov (teleskop + priemnik + komp'yuter + software) dlya obnaruzheniya ekzoplanet po variaciyam bleska ih svetil iz-za prohozhdenii po disku. Odnoi iz problem podobnyh ustanovok yavlyaetsya ogromnyi potok dannyh: dlya togo chtoby chasto obnaruzhivat' planety nado odnovremenno sledit' za bol'shim chislom zvezd s vysokim vremennym razresheniem (chtoby ne propustit' moment izmeneniya bleska) i s vysokoi tochnost'yu (0.01 zvezdnoi velichiny i luchshe) Sohranit' etot potok informacii nevozmozhno, poetomu ego obrabatyvayut v real'nom vremeni s ispol'zovaniem prostoi triggernoi shemy s dvumya urovnyami. Dlya obrabotki dannyh s bol'shih PZS (16000h16000 elementov), kotorye planiruetsya stavit' na podobnyi teleskop, budet dostatochno seti ne bolee chem iz 256 standartnyh rabochih stancii!

Sputnik INTEGRAL ochen' vazhen dlya evropeiskoi astronomii. Krome togo, on ochen' vazhen dlya Rossii. Pervym rezul'tatam etoi kosmicheskoi observatorii budet posvyashen special'nyi nomer Astronomy & Astrophysics. V etoi stat'e rasskazyvaetsya o edinom centre dannyh sputnika. Observatoriya yavlyaetsya mnogofunkcional'noi, ispoveduyushei politiku otkrytyh dannyh (spustya nekotoroe vremya posle nablyudenii vse materialy stanovyatsya dostupnymi mirovomu soobshestvu). Vse eto trebuet bystrogo i kachestvennogo predostavleniya dannyh vsem zhelayushim. Imenno etoi rabotoi zanimaetsya centr dannyh.

Astronomicheskih ob'ektov mnogo, a potomu mnogo dannyh.
Rabotat' s nimi (pover'te!) ochen' tyazhelo.
K schast'yu, raznoobraznye sovremennye tehnologii zdes'
ochen' pomogayut.
V stat'e rech' idet kak raz ob etom.
Krome astronomov stat'ya mozhet byt' ochen' interesna vsem tem,
kto zanimaetsya rabotoi s bol'shimi massivami dannyh.

Neironnye seti nahodyat mnozhestvo razlichnyh primenenii, v tom chisle i v obrabotke astronomicheskih dannyh (my neskol'ko raz pisali ob etom). Eta rabota yavlyaetsya dovol'no populyarnym obzorom po neiroinformatike, gde opisyvayutsya osnovnye principy, a takzhe reshennye i nereshennye problemy.
