NASA Astronomy Picture of the Day:

Normally faint and elusive, the Jellyfish Nebula is caught in this alluring telescopic field of view. Floating in the interstellar sea, the nebula is anchored right and left by two bright stars, Mu and Eta Geminorum, at the foot of the celestial twins. The Jellyfish Nebula itself is right of center, seen as a brighter arcing ridge of emission with dangling tentacles. In fact, this cosmic jellyfish is part of bubble-shaped supernova remnant IC 443, the expanding debris cloud from a massive star that exploded. Light from the explosion first reached planet Earth over 30,000 years ago. Like its cousin in astrophysical waters the Crab Nebula supernova remnant, the Jellyfish Nebula is known to harbor a neutron star, the ultradense remnant of the collapsed stellar core. An emission nebula cataloged as Sharpless 249 fills the field at the upper left. The Jellyfish Nebula is about 5,000 light-years away. At that distance, this image would be about 300 light-years across.

What does the universe look like through infrared goggles? Our eyes can only see visible light, but astronomers want to see more. Today’s APOD shows spiral galaxy IC 5332 as seen by two NASA telescopes: Webb in mid-infrared and Hubble in ultraviolet and visible light. To toggle between the two space-based views just slide your cursor over the image (or follow this link). The Hubble image highlights the spiral arms of the galaxy separated by dark regions, whereas the Webb image reveals a finer, more tangled structure. Interstellar dust scatters and absorbs light from the stars in the galaxy, causing the dark dust lanes in the Hubble image, and then emits heat in infrared light, so dust glows in this Webb image. The Mid-InfraRed Instrument on Webb needs to operate at a chilling temperature of -266ºC (or - 447ºF), otherwise it would detect infrared radiation from the telescope itself. Combining these observations, astronomers connect the “small scale” of gas and stars to the truly large scale of galactic structure and evolution.

By night when others soundly slept
And hath at once both ease and Rest,
My waking eyes were open kept
And so to lie I found it best.

I sought him whom my Soul did Love,
With tears I sought him earnestly.
He bow'd his ear down from Above.
In vain I did not seek or cry.

My hungry Soul he fill'd with Good;
He in his Bottle put my tears,
My smarting wounds washt in his blood,
And banisht thence my Doubts and fears.

What to my Saviour shall I give
Who freely hath done this for me?
I'll serve him here whilst I shall live
And Loue him to Eternity

Anne Bradstreet (née Dudley; (1612 – 1672) Born to a wealthy Puritan family in Northampton, England, she was the most prominent of early English poets of North America and first writer in England's North American colonies to be published. She is the first Puritan figure in American Literature and notable for her large corpus of poetry, as well as personal writings published posthumously. Read more

Rough-scaled python Morelia carinata. This snake species was only discovered in the seventies, and is Australia’s rarest snake. It also has the longest teeth of any species for its size, and is the only python with keeled scales..

"Pain is something most people experience after an injury, whether from a sprained ankle, surgery or car accident. Normally pain fades as the body heals. But it may last longer in women than in men, making women more likely to develop chronic pain". More at The Conversation ➜

NASA Astronomy Picture of the Day:

ver wonder what it would look like to crack open the Sun? The Egg Nebula, a dying Sun-like star, can unscramble this question. Pictured is a combination of several visible and infrared images of the nebula (also known as RAFGL 2688 or CRL 2688) taken with the Hubble Space Telescope. The star has shed its outer layers, and a bright, hot core (or "yolk") now illuminates the milky "egg white" shells of gas and dust surrounding the center. The central lobes and rings are structures of gas and dust recently ejected into space, with the dust being dense enough to block our view of the stellar core. Light beams emanate from that blocked core, escaping through holes carved in the older ejected material by newer, faster jets expelled from the star’s poles. Astronomers are still trying to figure out what causes the disks, lobes, and jets during this short (only a few thousand years!) phase of the star’s evolution, making this an egg-cellent image to study!
