Kleopatrah 5,024 Report post Posted February 19, 2019 (edited) Pentru ca in ultima vreme apar multe stiri intersante din astronomie si astrofizica, am deschis un topic unde sa postam si eventual sa discutam aceste stiri. Daca era deja un topic dedicat, rog unirea acestuia cu acel topic. Saturn isi pierde inelele. https://www.businessinsider.com/saturn-losing-rings-faster-than-thought-nasa-2018-12?IR=T&fbclid=IwAR0oF6jVjewDCq1kkuuQz3PHWKXz0dNpLtWQXaICC8H2iu-ILiAHTgncP0E Edited February 19, 2019 by Sherlock 2 Share this post Link to post Share on other sites

Enki 3,832 Report post Posted April 17, 2019 https://www.sciencealert.com/our-closest-neighbouring-star-has-a-planet-in-the-habitable-zone?fbclid=IwAR2exYhGBZGXSV94NyguLKxXI7bGRVcUn_tRwmZaUPdZa8l-LPDjgw6VcXI In 2016 se anunta descoperirea unei exoplanete in sistemul stelei pitice rosii Proxima Centauri, cel mai apropiat de noi la 4,2 ani lumina, iar planeta se situeaza in zona locuibila din acel sistem, cu o temperatura care permite starea lichida a apei. Desi se afla in zona locuibila, cercetarile au aratat ca nu ar fi favorabila vietii din motive ce tin de comportamentul instabil al piticelor rosii a caror eruptii solare bombardeaza cu radiatii planeta. un studiu facut la Carl Sagan Institute ale carui concluzii le gasiti aici http://news.cornell.edu/stories/2019/04/study-nearest-exoplanets-could-host-life iar studiul aici https://academic.oup.com/mnras/article/485/4/5598/5426502?searchresult=1 spune ca desi nu este potrivit mediul pentru a fi locuit de catre formele de viata pe care le stim acum din cauza radiatiilor, este foarte asemanator cu cel in care au aparut si s-au dezvoltat primele forme de viata de pe Terra. 1 Share this post Link to post Share on other sites
