Miliardi di pianeti nella Via Lattea possono ospitare la vita

Ci sono oltre 6 miliardi di esopianeti come la Terra nella nostra galassia, la ricerca degli scienziati. Uno studio del 2020 calcola in oltre 6 miliardi di esopianeti simili alla nostra Terra presenti nella sola Via Lattea, la nostra galassia: i dettagli. Possono esistere fino a un pianeta simile alla Terra per ogni cinque stelle simili al Sole nella Via Lattea, secondo le stime del 2020 degli astronomi dell’Università della Columbia Britannica che utilizzano i dati della missione Kepler della NASA (missione terminata). Per essere considerato simile alla Terra, un pianeta deve essere roccioso con un diametro simile a quello terrestre e in orbita attorno a stelle come il Sole (tipo G).

Hurt (SSC-Caltech) Inoltre gli esopianeti devono orbitare nelle zone abitabili delle proprie stelle, la giusta distanza affinché ci sia una temperatura atta a poter “ospitare” acqua liquida, e potenzialmente vita, sulla sua superficie. Un numero enorme di pianeti extrasolari Le stime precedenti della frequenza dei pianeti simili alla Terra andavano da circa 0,02 pianeti potenzialmente abitabili (per stella simile al Sole) ad uno. In genere, i pianeti come la Terra sono più difficili da individuare rispetto agli altri tipi, poiché sono piccoli e orbitano lontani dalle loro stelle. Ciò significa che un catalogo planetario rappresenta solo un piccolo sottoinsieme dei pianeti che sono effettivamente in orbita attorno alle stelle. Gli scienziati hanno usato una tecnica nota come “modellazione in avanti” per superare questi limiti. Il radius gap La ricerca ha anche fatto luce su una delle questioni più importanti della scienza degli esopianeti: il “radius gap” dei pianeti. Il divario di raggio dimostra che non è comune per i pianeti, con periodi orbitali inferiori a 100 giorni, avere una dimensione compresa tra 1,5 e 2 volte quella della Terra. I ricercatori hanno scoperto che il divario del raggio esiste in un intervallo molto più ristretto di periodi orbitali di quanto si pensasse in precedenza. La ricerca continua!

Dreams maybe do come true

On February 19th 2018 I was so frustrated. Will I go to UBC or will I not? I was thinking about it so much that I even had a dream about getting an acceptance letter from UBC. The next morning I very hesitantly checked my email. Nothing from UBC. Then I checked my SSC. And there it was “Congratulations!” I was in shock and felt tears rolling down my cheeks. I finally made it. I made everyone in my life including myself proud, I showed it to my haters that I’m worth so much more than what they saw me as. It was time to leave. It was time to go 22 hours away from home. I was excited, nervous and sad. Leaving family is always hard. Leaving your childhood home is so hard. But I was also looking forward to living a new life. A different life. I was lucky enough to find the most amazing group of girls in the first week of university itself. They are so supportive and still continue to hype me up. They constantly boost my morale. I started feeling better about myself. I started feeling competent specially when I wasn’t afraid of doing things by myself. Going off campus alone, eating alone, and so on. There was a different kind of freedom. I started falling in love with city of Vancouver and started falling in love with myself and the people around me, started feeling so grateful and blessed. University was everything I expected. Although my academics aren’t the best and I don’t feel fully accomplished, l know that the things I am taking back with me are life skills and lessons.

July 1983 map:

The map is up to 519 sites in North America plus 29 sites in Europe. and 1 in Australia. It is becoming increasingly three-dimensional. Because of this, there is one crossover on the map, as well as a number (16) of connections that are keyed in with numbers (so that (1) connects to (1) and so on). Reading the map: -, |, and + indicate connections. Lines never pass through a +, which always indicate where the connecting line ends or changes direction. Logical buses are represented by =. This means that a site such as hplabs is indicated by the entire string of characters as follows: +====+=hao===+====+. olduse.net \ (wormhole to 2013) USENET LOGICAL MAP - July 10,1983 \ Karen Shannon

"Logical buses" are denoted by "=" or "+". A logical bus is merely a way of providing more space to indicate connections to a site. For example, hplabs is represented by the character string "+===hplabs===+". Places on the map where a dash and vertical bar intersect do not represent actual intersections, but rather crossovers (think of them as a highway over/underpass). Unlike the last logical map, there has been no attempt made to differentiate between various types of networks, largely because that information is difficult to obtain.
