Inside star cluster NGC 602, a star-forming region in the Small Magellanic Cloud, bright, blue, newly formed stars are blowing a cavity in this nebula,sculpting the inner edge of its outer portions, slowly eroding it away and eating into the material beyond. The diffuse outer reaches of the nebula prevent the energetic outflows from streaming away from the c...

寻找失踪的黑洞

Despite searching with NASA’s Chandra X-ray Observatory and Hubble Space Telescope, astronomers have no evidence that a distant black hole estimated to weigh between 3 billion and 100 billion times the mass of the Sun is anywhere to be found. This missing black hole should be in the enormous galaxy in the center of the galaxy cluster Abell 2261, which ...
