Consequence-free Cosmology

Consequence-free Cosmology

Aug 12, 2015 These two galaxies appear to be elbowing each other with their spiral arms. The consensus interpretation is that they’re colliding and generating shock waves that initiate gravitational collapse of gas clouds. The collapsing clouds become stars, many of which are extremely massive. These quickly run through their theoretical ...

Notes on an Incipient Cosmos Part One [DO NOT RE-RUN]

Notes on an Incipient Cosmos Part One [DO NOT RE-RUN]

Aug 10, 2015 New sights for old eyes We live in a constellation Of patches and of pitches…, Thinkers without final thoughts In an always incipient cosmos…. –Wallace Stevens, July Mountain The Big Bang appears to be the final thought of astronomical scientific endeavor. The verified theories of gravity, gas ...

Co-Dependent

Co-Dependent

Aug 7, 2015 Sometimes, one theory depends on another one to survive. According to a recent press release, the largest observable structure in the Universe was identified by a team of astronomers from Hungary and the United States. The vast ring of galaxies, over five billion light years in diameter, ...

Arcos Rojos

Arcos Rojos

Aug 6, 2015 What causes colorful streaks on Tethys? As reported in previous Pictures of the Day, maps of Mimas, Enceladus, Rhea, and Dione show that they are red to some degree. All the latest maps indicate that most of them are redder on their trailing hemispheres. No one is ...

Saturn Supernova

Saturn Supernova

Aug 5, 2015 Shockwave: a compressional wave of high amplitude caused by a shock (as from an earthquake or explosion) to the medium through which the wave travels. The plasmasphere of Saturn is highly energetic, enough so that, when the Cassini orbiter sent images to Earth, lightning up to a million times more powerful ...

The Colors of Thought

The Colors of Thought

Aug 4, 2015 M47 is an open cluster of fewer-than-usual stars. The contrasting colors of blue and red have an aesthetic appeal. One can even detect a few orange and yellow stars. A person may glimpse an occasional green one, especially if that person fiddles with the RGB settings in Photoshop ...

The Great Beguiler

The Great Beguiler

Aug 3, 2015 Galaxy clusters are thought to be pulled by a force emanating from "beyond the horizon" of the Universe. Astronomers believe that the Universe is expanding at an ever accelerating rate. Contemporary theories suggest that galaxies are receding from us because they started out receding from us due to ...

Cellular Plasmas

Cellular Plasmas

Jul 31, 2015 Astronomical theories predict a white dwarf star that can not be found. In the nuclear view, a planetary nebula is the result of a dying star that has exhausted its hydrogen/helium fuel supply and collapsed under gravitational compression. The stellar implosion rebounds off the core, throwing massive amounts ...

And Yet They Move

And Yet They Move

Jul 30, 2015 Io's caldera continue to puzzle scientists. Previous Pictures of the Day discuss several confirmed predictions about electrical activity on Io, notably, the intense electric arcing between the moon and its parent body, Jupiter. Images of Io verify that Io ought to be considered from an electric discharge hypothesis, ...

How You Know

How You Know

Jul 29, 2015 Another epistemological tour de force. Probable, Possible, my black hen, She lays eggs in the Relative When. She doesn't lay eggs in the Positive Now Because she's unable to postulate how. --- The Space Child's Mother Goose By Frederick Winsor People don't pay much attention to "how" they ...

Dynamic Asteroids

Dynamic Asteroids

Jul 28, 2015 Electrically active objects dominate the Solar System Small planetoids, called Near Earth Objects (NEO), are a concern for space scientists because it is thought that large rocks might strike our planet with devastating force. It is a commonly held belief that such an object caused the extinction ...

Nebular Lights

Nebular Lights

Jul 27, 2015 What creates X-ray emissions in nebulae? From gamma rays down through X-rays and extreme ultraviolet, conventional theories rely upon gravity and acceleration as the only way for them to be produced in space. Compression of hydrogen gas and dust is supposed to create enough transfer of momentum ...

Martian Plumes

Martian Plumes

Jul 24, 2015 Wispy clouds are seen hundreds of kilometers above Mars. Recently, planetary scientists announced the discovery of giant plumes reaching up to 250 kilometers from the Martian surface. Agustin Sanchez-Lavega of the Universidad del País Vasco in Spain wrote in the journal, Nature: “One idea we’ve discussed is ...

The X Factor

The X Factor

Jul 23, 2015 Consensus black hole theory called into question again. "The largest X-ray flare ever detected from the supermassive black hole at the center of the Milky Way galaxy" was recently announced by the Chandra X-ray Telescope observation team. According to the report, the extreme energy calls into question ...

Electrical Hierarchy

Electrical Hierarchy

Jul 22, 2015 Elves could be found in gas giant atmospheres. The plasmasphere of Saturn is highly energetic. The Cassini orbiter found lightning up to a million times more powerful than anything on Earth. It is not surprising that the discovery was made, since Saturn emits 2.3 times more energy than it receives ...

Trial and Tribulation

Trial and Tribulation

Jul 21, 2015 One of the Mars Exploration Rovers is still going strong. Recently, the Opportunity rover on Mars focused its camera on a grand vista from the summit of Cape Tribulation at the highest point of Endeavor crater's rim—a view extending for more than 40 kilometers. Considering that its mission ...

Another Fogged Image of Stephan’s Quintet

Another Fogged Image of Stephan’s Quintet

July 20, 2015 This image of Stephan’s Quintet is befogged with the same obsolete commentary as previous images: the foreground galaxy, collisions, shock waves, and heat. Editor's note: Please enjoy this Picture of the Day from July 20, 2009. The foreground galaxy (bottom left) is believed to be in the ...

Moon to Moon

Moon to Moon

Jul 17, 2015 Charon and Earth's Moons bear a striking resemblance. Pluto's moon, Charon was discovered by astronomer James Christy on June 22, 1978 when he noticed a "bulge" on the disk of Pluto that was subsequently found in telescope images as far back as 1965. Charon is a frozen, ...

Rhea's Debris Disc

Rhea’s Debris Disc

Jul 16, 2015 Evidence for the dust cloud came from a gradual drop on either side of Rhea in the number of electrons detected by two of Cassini's instruments. Scientists from the Jet Propulsion Laboratory in Pasadena, California discovered a “debris ring” surrounding Saturn’s frigid moon, Rhea. The Cassini space probe, ...

Dark Clusters

Dark Clusters

Jul 15, 2015 A recent press release announces the discovery of so-called "dark galaxies" in the Coma Cluster. Pieter van Dokkum of Yale University wrote: “On Coma’s outskirts lurk 47 galaxies similar in size to the Milky Way — but with 1,000 times fewer stars. To survive in crowded Coma, ...

Captives of Simplifying Assumptions

Captives of Simplifying Assumptions

Jul 14, 2015 "Our choicest plans have fallen through, our airiest castles tumbled over, because of lines we neatly drew and later neatly stumbled over." --- Piet Hein GROOKS I was checking out the dynamics describing the orbit of SOHO, the sun-watching satellite oscillating around a mathematical point in empty space, ...

Macrocosmic Charge

Jul 13, 2015 What are galaxies? Gal·ax·y /'ɡaləksē/ noun; plural noun: galaxies. A system of millions or billions of stars, together with gas and dust, held together by gravitational attraction. Modern astronomers suggest that galaxies are clouds of hydrogen gas and intergalactic dust that were assembled by gravity billions of ...

Galactic Speedway

Galactic Speedway

Jul 10, 2015 Does gravity power stellar behavior? Modern astronomical models of cosmic evolution rely on the kinetic effects of cold gas collapsing from gravitational forces. Clouds of gas and dust a thousand times less dense than a puff of smoke are said to be compressed into a region of ...

X-ray Eruption

X-ray Eruption

Jun 09, 2015 Stellar flares are seen in unexpected places. In a September 30, 2014 press release, NASA officials from the Goddard Space Flight Center announced that their SWIFT satellite detected a stellar flare with X-ray emissions larger than anything they expected to witness from DG Canum Venaticorum, a "normal" red ...

Astronomy in Collision

Astronomy in Collision

Jul 8, 2015 Modern astronomy is like a blind man, panicked, without his cane, running. There are collisions. It’s not because astronomy has lost its sight; it’s because it has gained a second sight, another sense beyond the five that evolved. It has gained a sixth extrasensory perception conferred by ...
