Astrophisics
- Lunar surface from Appolo 15
- Joe Rogan - Brian Cox (black hole)
- how does the sun affects the temperature of earth
a) earth turns under it's axis (23.5 grade from the axis)b) North pole is always pointing to polaris (north star)
c) a rotation approx 24 hours (under axis) and a revolution 365 days (and a quarter),around Sun.
d) the distance between sun and earth is not equal always during the revolution perihelion 147 mil km (jan 1) and aphelion 152 mil km (july 4).
- The days in the northern emisphere in aphelion are higher and the temperature is higher.
-The days in the souther emispher because of the angle from axis (jan 1) is summer.
- Geomagnetic storms and solar flare
a) a geomagnetic storm can reach earth in 8 minutes.
b) the maximum of the solar acrivity this time can be in 2025.
- Comet C/2023 A3 (Tsuchinshan-ATLAS)
Poti sa o vezi maine la 7.30
Pana pe la 8 si ceva
Imediat dupa apusul soarelui
Ca ea se duce dupa soare
da, fiind imediat deasupra Soarelui la apus, se ducea si ea destul de repede in jos
teoretic isi pastreaza cam toata luna pozitia
insa nu se stie cat de mult o sa isi pastreze luminozitatea
si nu se stie cand si cum mai avem asa senin
dar o data la 5-10 ani apare una vizibila cu ochiul liber
ultima a fost Neowise, prin 2019 parca
