A Planetary Nebula Like This Will Only be Visible for About 10,000 Years Before it Fades Away

   25 Jan 01:00:01   |  Universe Today

For some stars, their last act is a final exhalation of gases, which we call a planetary nebula. While a living being’s last breath is closely followed by death, a star can continue to shine. And that shining illuminates the final exhalation of gases like a cosmic, diaphanous veil. Astronomers have captured one such planetary …

An almost unimaginably enormous black hole is situated at the heart of the Milky Way. It’s called a Supermassive Black Hole (SMBH), and astronomers think that almost all massive galaxies have one at their center. But of course, nobody’s ever seen one (sort of, more on that later): It’s all based on evidence other than …
