NASA Astronomy Picture of the Day:

What is a pair of headphones doing in the sky? Today’s image features the Headphone Nebula, also known as PK 164 +31.1 or Jones-Emberson 1. This planetary nebula, the remnant of a dying Sun-like star, faintly occupies an angular region of the Lynx constellation about 1/5th the diameter of the full moon. The red and blue-ish green colors trace hydrogen and oxygen atoms, respectively, that have been excited and ionized by the nebula's central white dwarf. The headphone shape, where two lobes of hydrogen puncture the inner region of oxygen, adds this object to a long list of oddly shaped nebulae. The morphology of such strange nebulae hint at the presence of a stellar or planetary companion, which can stir the material flowing out from the dying star. You can listen to Hubble and JWST sonifications of planetary nebulae through your very own headphones!

NASA Astronomy Picture of the Day:

The upper galaxy might be more photogenic, but the lower galaxy is more unusual. The galaxy up top is NGC 3660, a spiral galaxy similar to our own Milky Way galaxy in that it has several bright blue spiral arms and a central bar of stars, dust, and gas. Captured by chance in the featured deep and colorful image, surprisingly, is SN 2026cff, a supernova found just to the right of the central bar. Farther in the distance is the bottom galaxy, known informally as Burçin’s galaxy, but formally cataloged as LEDA 1000714. The center of this galaxy appears to be an old elliptical galaxy, but it is strangely surrounded by not one but two rings of stars. What created Burçin's galaxy is a mystery and remains a continuing topic of research, but it likely involves the accretion of one or more smaller galaxies.

What are these strange space globs? Situated in rich star fields and glowing hydrogen gas, these opaque clouds of interstellar dust and gas are so large they might be able to form stars. Their home is known as IC 2944, a bright stellar nursery located about 7,600 light years away toward the constellation of the Centaur (Centaurus). The largest of these dark globules, first spotted by A. D. Thackeray in 1950 using a telescope in South Africa, is likely two separate but overlapping clouds, each more than one light-year wide. Along with other data, the featured Hubble palette image from the El Sauce Observatory in Chile, indicates that Thackeray's globules are fractured and churning as a result of intense ultraviolet radiation from young, hot stars already energizing and heating the bright emission nebula. These and similar dark globules known to be associated with other star forming regions may ultimately be dissipated by their hostile environment -- like cosmic lumps of butter in a hot frying pan.

    Immortality 

Do not stand
By my grave, and weep.
I am not there,
I do not sleep,
I am the thousand winds that blow
I am the diamond glints in snow
I am the sunlight on ripened grain,
I am the gentle, autumn rain.
As you awake with morning’s hush,
I am the swift, up-flinging rush
Of quiet birds in circling flight,
I am the day transcending night.
Do not stand
By my grave, and cry—
I am not there,
I did not die.

Poem by Clare Harner, (Published in "The Gypsy", December 1934 - page 16). The poem is often attributed to anonymous or incorrect sources. Harner, wrote the verses in late 1934, attempting to cope with her grief, after the unexpected death of her brother.by presenting death, not as an ending but a transformation.
