The biased distribution of the early dwarf galaxies where the first stars formed should result in an age gradient with radius of the low-metallicity stars in the Milky Way, with the oldest ones concentrated in the bulge and the youngest in the outer halo....

Beyond a wholesome discipline, be gentle with yourself. You are a child of the universe, no less than the trees and the stars; you have a right to be here. And whether or not it is clear to you, no doubt the universe is unfolding as it should. Therefore be at peace with God, wha...
根据下句These black holes have masses that are more than one million suns together.可知这些黑洞的质量超过一百万个太阳.所以大黑洞被称为"超自然的黑洞"是有原因的,因此答案是D. 5.D.主旨大意题.根据倒数第二段Scientists can study stars to find out if they are flying around, or orbiting a black...
IMFs are hardcoded into Sunscreen. The IMF is calculated by calling the IMF wrapper function. It returns a quantity of the form dN/dM*, the number of stars per infitesimal stellar mass range per unit solar mass of stellar population. All these masses are in units of Msun. Most of the ...
But the elements are still products of stars and would still be present in planetesimals everywhere. No matter what kinds of life we are looking for, we are likely to find the necessary elements on almost every planet, moon, asteroid, and comet in the universe. [#paragraph5]A somewhat ...
The special tools can see how stars near black holes act differently from other stars.Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom*. These black holes are very tiny but have the mass* of a large mountain. Mass is the amount ...
Stars are formed out of clouds of gas and dust in interstellar space that begin to collapse and flatten into a disk. During this time grains of dust and ice come together and grow larger over time. When objects grow as big as the giant planets, any smaller (km-scale) bodies called plan...
Imagine two newly formed planets orbiting at the same distance from their respective stars, each starting with a rocky core and a substantial hydrogen-helium gas envelope. Planet A has a lower mass and weaker gravity, so it can’t hold on to its atmosphere as the star pumps energy into it...
