Let's say, for the sake of speculation, we acquire the technology necessary to travel to the outer edge of one of the spiral arms of our galaxy. We go to a star in this "outer rim" and land on a pl…
Agar bizda $ rho (r) = rho_c (1-r / R) $ yulduz zichligi modeli mavjud bo'lsa, bu erda yulduz o'zini nisbiy bo'lmagan degeneratsiyaga ega bo'lgan mukammal gaz va elektron kabi tutadigan ionlardan iborat. Markaziy bosim t…
Jupiter is currently shrinking due to the Kelvin-Helmholtz mechanism. Will this mechanism eventually hold or getting slower? If so, at what size of Jupiter will it stop and why? If not, what will
What is the inclination of Mercury's orbit w.r.t. the Sun's equatorial plane? Additionally, what is the orientation of Mercury's orbit (long axis) w.r.t. the Milky Way?
Kashf etilgan ekzoplaneta tizimlarining katta qismi, ehtimol bizning quyosh tizimimizga qaraganda yulduzga yaqinroq masofada joylashgan bir nechta gaz gigantini o'z ichiga oladi. Ma'lumki, Quyosh tizimida evo…
The cosmic microwave background radiation should provide kind of a global reference frame, because you can determine your speed relative to it using the redshift. Is it known how fast we are movin…
