The age of the Milky Way Galaxy is estimated to be 11 to 13 billion years old, whereas the age of the Universe is estimated to be 10 to 15 billion years old. Who was the first to calculate the Earth's radius? Eratosthenes was the first person to mathematically calculate the diameter ...
Distance and Location:Positioned in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, WOH G64 resides at a distance of approximately 160,000 light years (50,000 parsecs) from Earth. It is located in the southern constellation of Dorado. ...
Approximately how long does it take the sun to orbit the center of the milky way galaxy? Is our Sun a binary star? What is the mass of the Sun? Transit curves show that planet X has an orbital period of 70.5 da...
The integrated metallicity profile of the Milky Way The heavy element abundance profiles of galaxies place stringent constraints on galaxy growth and assembly history. As the Milky Way is currently the only spiral galaxy in which we can measure temporally resolved chemical abundances, it ... J Lian...
Besides the eccentricity of the satellite orbit, the tidal radius depends also on the ratio of the satellite internal angular velocity to the orbital angular velocity. We compare our formula to the results of two $N$-body simulations of dwarf galaxies orbiting a Milky Way-like host on a ...
We find substantial agreement between model isochrones and Milky Way globular cluster parameters, which suggests that there is a balance between the flow of energy and the central energy production for almost all globular clusters. We also find that the majority of the globular clusters are still ...
Perhaps most significantly, NTT observations of stars orbiting the centre of our Milky Way helped determine the mass and the radius of its supermassive black hole, effectively helping confirming the existence of such a massive and compact object. 或許最重要的是,NTT對環繞銀河系中心恆星的觀測,可以...
What is the angular size of the Andromeda galaxy? If the sun's mass is about average, how many stars are there in the Milky Way galaxy? The mass of the sun is of the order of 10^{30} kg How many Earths can fit in VY Canis Majoris? How ...
