What is the newest galaxy found?
Astronomers discover massive radio galaxy 100 times larger than the Milky Way. Its discovery was “a stroke of luck.” A joint radio-infrared view of Alcyoneus, a radio galaxy with a projected proper length of 5.0 megaparsecs.
What if Jupiter fell into the sun?
If Jupiter were mixed throughout the sun, the temperature of the sun would decrease slightly, and perhaps it would take a few hundred years for the sun’s temperature to return to its previous level, and maybe we would get a few basis points less solar radiation, but it wouldn’t go out. Highly active question.
