<<This image from NASA's Wide-field Infrared Survey Explorer (WISE) takes in several interesting objects in the constellation Cassiopeia, none of which are easily seen in visible light.
The red circle visible in the upper left part of the image is SN 1572, often called "Tycho's Supernova." This remnant of a star explosion is named after the astronomer Tycho Brahe, although he was not the only person to observe and record the supernova. When the supernova first appeared in November 1572, it was as bright as Venus and could be seen in the daytime. Over the next two years, the supernova dimmed until it could no longer be seen with the naked eye. It wasn't until the 1950s that the remnants of the supernova could be seen again with the help of telescopes.
When the star exploded, it sent out a blast wave into the surrounding material, scooping up interstellar dust and gas as it went, like a snow plow. An expanding shock wave traveled into the surroundings and a reverse shock was driven back in toward the remnants of the star. Previous observations by NASA's Spitzer Space Telescope indicate that the nature of the light that WISE sees from the supernova remnant is emission from dust heated by the shock wave.
In the center of the image is a star-forming nebula of dust and gas, called S175. This cloud of material is about 3,500 light-years away and 35 light-years across. It is being heated by radiation from young, hot stars within it, and the dust within the cloud radiates infrared light. On the left edge of the image, between the Tycho supernova remnant and the very bright star, is an open cluster of stars, King 1, first catalogued by Ivan King, an astronomer at UC Berkeley, Calif. This cluster is about 6,000 light-years away, 4 light-years across and is about 2 billion years old.
Also of interest in the lower right of the image is a cluster of infrared-emitting objects. Almost all of these sources have no counterparts in visible-light images, and only some have been catalogued by previous infrared surveys. There are indications that they may be young stellar objects associated with a dense nebula in the area. Young stellar objects (YSOs) are stars in their earliest stages of life. YSOs are surrounded by an envelope of dust, which would explain the very red color of the sources in this image.
All four infrared detectors aboard WISE were used to make this mosaic. The image spans an area of 1.6 x 1.6 degrees on the sky or about 3 times as wide and high as the full moon. Color is representational: blue and cyan represent infrared light at wavelengths of 3.4 and 4.6 microns, which is dominated by light from stars. Green and red represent light at 12 and 22 microns, which is mostly light from warm dust.>>

- JOYCE: Ulysses, Scylla & Charybdis
STEPHEN: (Stringendo) He has hidden his own name, a fair name, William,- in the plays, a super here, a clown there, as a painter of old Italy
set his face in a dark corner of his canvas. He has revealed it in the
sonnets where there is Wil{L IN OVER}plus. Like John o’Gaunt his name
is dear to him, as dear as the coat and crest he toadied for, on a bend
sable a spear or steeled argent, honorificabilitudinitatibus, dearer
than his glory of greatest shakescene in the country. What’s in a
name? That is what we ask ourselves in childhood when we write the name
that we are told is ours. A star, a daystar, a firedrake, rose at his
birth. It shone by day in the heavens alone, brighter than Venus in the
night, and by night it shone over delta in Cassiopeia, the recumbent
constellation which is the signature of his initial among the stars.
His eyes watched it, lowlying on the horizon, eastward of the bear,
as he walked by the slumberous summer fields at midnight returning
from Shottery and from her arms.
Both satisfied. I too.
Don’t tell them he was nine years old when it was quenched.
And from her arms.
Wait to be wooed and won. Ay, meacock. Who will woo you?
Read the skies. Autontimorumenos. Bous Stephanoumenos. Where’s your
configuration? Stephen, Stephen, cut the bread even. S. D: sua donna.
Già: di lui. Gelindo risolve di non amare S. D.
—What is that, Mr Dedalus? the quaker librarian asked. Was it a
celestial phenomenon?
—A star by night, Stephen said. A pillar of the cloud by day.

At London printed for N.L. and Iohn Trundell. 1603.
Barnardo: Sit downe I pray, and let vs once againe - Assaile your eares that are so fortified,
What we haue two nights seene.
Horatio: Wel, sit we downe, and let vs heare Bernardo speake of this.
Barnardo: Last night of al, when yonder starre that's west- - ward from the pole, had made his course to
Illumine that part of heauen. Where now it burnes,
The bell then towling one.
