Mirach’s Ghost

Explanation: As far as ghosts go, Mirach’s Ghost isn’t really that scary. In fact, Mirach’s Ghost is just a faint, fuzzy galaxy, well known to astronomers, that happens to be seen nearly along the line-of-sight to Mirach, a bright star. Centered in this star field, Mirach is also called Beta Andromedae. About 200 light-years distant, Mirach is a red giant star, cooler than the Sun but much larger and so intrinsically much brighter than our parent star. In most telescopic views, glare and diffraction spikes tend to hide things that lie near Mirach and make the faint, fuzzy galaxy look like a ghostly internal reflection of the almost overwhelming starlight. Still, appearing in this sharp image just above and to the right of Mirach, Mirach’s Ghost is cataloged as galaxy NGC 404 and is estimated to be some 10 million light-years away.

Mirach’s ghost is, in itself, not a very interesting galaxy. A small plain looking E-S0 type galaxy. However, its postion about 7 arc minutes from the 2nd magnitude M0 star beta And – known as Mirach – makes it into an interesting photographic target.

Ann Druyan, talking about her husband, Carl Sagan

“When my husband died, because he was so famous & known for not being a believer, many people would come up to me — it still sometimes happens — & ask me if Carl changed at the end & converted to a belief in an afterlife. They also frequently ask me if I think I will see him again. Carl faced his death with unflagging courage & never sought refuge in illusions. The tragedy was that we knew we would never see each other again. I don’t ever expect to be reunited with Carl. But, the great thing is that when we were together, for nearly twenty years, we lived with a vivid appreciation of how brief & precious life is. We never trivialized the meaning of death by pretending it was anything other than a final parting. Every single moment that we were alive & we were together was miraculous — not miraculous in the sense of inexplicable or supernatural. We knew we were beneficiaries of chance… That pure chance could be so generous & so kind… That we could find each other, as Carl wrote so beautifully in Cosmos, you know, in the vastness of space & the immensity of time… That we could be together for twenty years. That is something which sustains me & it’s much more meaningful…

The way he treated me & the way I treated him, the way we took care of each other & our family, while he lived. That is so much more important than the idea I will see him someday. I don’t think I’ll ever see Carl again. But I saw him. We saw each other. We found each other in the cosmos, and that was wonderful.“

The God Helmet

Neuroscientist Michael Persinger uses helmet with solenoids to stimulate the brain with magnetic fields inducing a sense of presence of beings such as angels, demons, ghosts, and aliens.
