black hole

NASA began "sonifying" its famous photos of outer space to help people who are visually impaired enjoy the images. Recently, it recreated the sound of a black hole 240 million light-years away.

The black hole is roughly 1,000 light-years from Earth — and more than 2,000 light-years closer than the next one known. What's more, scientists say, it may be just "the tip of an exciting iceberg."
