UnverifiedGalaxy clusters are often used as cosmological probes, and the evolution of their number with redshift is highly sensitive to the nature of dark energy and the expansion history of the universe.66% similarUnverifiedExtreme star-forming galaxies refer to galaxies with abnormally high rates of star formation.62% similarUnverifiedThe core challenge of directly imaging exoplanets is that a star's brightness is often billions of times that of its planets.58% similarUnverifiedIf some quasar samples are actually star-forming galaxies, conclusions such as the number density of supermassive black holes and the quasar luminosity function in the early universe may need to be recalibrated.57% similarUnverifiedThe star type with the largest radius in the known universe is the red supergiant, whose radius can reach about two thousand times that of the Sun, close to nine astronomical units; if placed at the Sun's position, its surface would engulf everything from Mercury to Jupiter and almost reach Saturn's orbit.57% similar
