Astronomers usually cannot tell the age of an individual star. There are certain stars that we know are very young, and others that are very old, but for most stars we cannot tell. When we have a large group of stars, however, we can tell its age. This is possible because all of the stars in a cluster are presumed to have begun their life at approximately the same time. After a relatively brief time (in 'star time,' that is--we are talking thousands to millions of years here) stars reach the adult phase of their life, which we call the main sequence phase. The length of time a star spends in the main sequence phase depends on its mass. "Constructing a plot, called the HR diagram, of the stars in the cluster, scientists can determine the mass of the stars that are just ending this phase and moving on to the next phase of their life, the red giant phase. Computer models allow us to predict how old a star of that mass must be to be at that juncture of its life, and hence to estimate the age of the cluster. Recently, this procedure has come under close scrutiny because that age it gives for the oldest star clusters in our Milky Way seems to be older than the age of the universe derived from the most recent Hubble Space Telescope data."

NASA will provide live coverage of the return of astronauts Robert Behnken and Douglas Hurley to Earth in SpaceX's Dragon "Endeavour" spacecraft. They're scheduled to leave the International Space Station at 7:34 p.m. EDT Aug. 1 and splash down at 2:42 p.m. EDT Aug. 2. The pair have been onboard our orbiting laboratory since May 31 - Do you agree with this post? 💯 ❗️Follow us    for more Space Science Facts❗️ @_space___lover_ @_space___lover_ @_space___lover_ @_space___lover_ @_space___lover_ Double tap ❤️ Share More👇 Follow us for more 🌍 -tag:-) #nasa  #galaxies #spacetravel #universes #earthplanet #nasabeyond #spacescience #futures #alieninvasion #elonmusk  #humanscale #astrogeekz #dangeroustour #himalayas #_space___lover_ #plutoretrograde #tomcruire  #physicsisfun #theoreticalphysics (at ISS) https://www.instagram.com/p/CDRK_EPnDRp/?igshid=1jbeodnlip4mx

𝐀𝐧𝐨𝐮𝐬𝐡𝐞𝐡 𝐀𝐧𝐬𝐚𝐫𝐢 was the world's first woman space tourist.🌌 . Anousheh Ansari is an Iranian American engineer and co-founder and chairwoman of Prodea Systems. Her previous business accomplishments include serving as co-founder and CEO of Telecom Technologies, Inc. (TTI). The Ansari family is also the title sponsor of the Ansari X Prize. On September 18, 2006, a few days after her 40th birthday, she became the first Iranian and first female Muslim in space. Ansari was the fourth overall self-funded space tourist, and the first self-funded woman to fly to the International Space Station. Her memoir, My Dream of Stars, co-written with Homer Hickam, was published by Palgrave Macmillan in 2010. https://www.instagram.com/p/CDnSR2rD-tw/?igshid=9z06k0hf64xu
