I've been looking for an older bit of research and this is likely the group that may have seen it. Years ago (well before YouTube) I ran across a study of heating and cooling of metal in zero G and the odd properties there in. There where a few mpeg videos showing the odd cooling process that happens. i.e. the mass (which has formed itself into a near perfect sphere) goes to cool, but as there is nothing to cause one part to cool faster than the others, it does the phase change from a liquid to a solid in one step for the whole mass, releasing the energy in the form of a light pulse. Does anyone else remember seeing this? There were some additional videos of the odd properties of the metal sphere in gravity (they where showing it bounce in a clear plastic tube relative to a similar sphere cast from the same material in normal G)

I used to have a lot of trouble visualizing just where and how the Oort clouds came into it all. This diagram explains it very well.

An article published in the journal "Nature Communications" describes a research on the craters found on the surface of the dwarf planet Ceres by NASA's Dawn space probe. A team of scientists led by Simone Marchi of the Southwest Research Institute in Boulder argues that there are fewer large craters than expected and the reason is that were obliterated.

Hi,

Lights sprawl toward the horizon in this night skyscape from Uludag National Park, Bursa Province, Turkey, planet Earth. The stars and nebulae of the Milky Way are still visible though, stretching above the lights on the northern summer night while three other planets shine brightly. Jupiter is at the far right, Mars near the center of the frame, and Saturn is just right of the bulging center of our galaxy. Because the panoramic scene was captured on July 6, all three planets pictured were hosting orbiting, operational, robotic spacecraft from Earth. Popular Mars has five (from three different space agencies): MAVEN (NASA), Mars Orbiter Mission (India), Mars Express (ESA), Mars Odyssey (NASA), Mars Reconnaissance Orbiter (NASA). Ringed Saturn hosts the daring Cassini spacecraft. Just arrived, Juno now orbits ruling gas giant Jupiter.

Cassiopia A - Glowing remains of an old supernova

Glowing gaseous streamers of red, white, and blue — as well as green and pink — illuminate the heavens like Fourth of July fireworks. The colorful streamers that float across the sky in this photo taken by NASA's Hubble Space Telescope were created by one of the biggest firecrackers seen to go off in our galaxy in recorded history, the titanic supernova explosion of a massive star. The light from the exploding star reached Earth 320 years ago, nearly a century before our United States celebrated its birth with a bang.

The dead star's shredded remains are called Cassiopeia A, or "Cas A" for short. Cas A is the youngest known supernova remnant in our Milky Way Galaxy and resides 10,000 light-years away in the constellation Cassiopeia, so the star actually blew up 10,000 years before the light reached Earth in the late 1600s.

This stunning Hubble image of Cas A is allowing astronomers to study the supernova's remains with great clarity, showing for the first time that the debris is arranged into thousands of small, cooling knots of gas.

The dead star's shredded remains are called Cassiopeia A, or "Cas A" for short. Cas A is the youngest known supernova remnant in our Milky Way Galaxy and resides 10,000 light-years away in the constellation Cassiopeia, so the star actually blew up 10,000 years before the light reached Earth in the late 1600s.

This stunning Hubble image of Cas A is allowing astronomers to study the supernova's remains with great clarity, showing for the first time that the debris is arranged into thousands of small, cooling knots of gas. This material eventually will be recycled into building new generations of stars and planets. Our own Sun and planets are constructed from the debris of supernovae that exploded billions of years ago.

This photo shows the upper rim of the supernova remnant's expanding shell. Near the top of the image are dozens of tiny clumps of matter. Each small clump, originally just a small fragment of the star, is tens of times larger than the diameter of our solar system.

The colors highlight parts of the debris where chemical elements are glowing. The dark blue fragments, for example, are richest in oxygen; the red material is rich in sulfur.

The star that created this colorful show was a big one, about 15 to 25 times more massive than our Sun. Massive stars like the one that created Cas A have short lives. They use up their supply of nuclear fuel in tens of millions of years, 1,000 times faster than our Sun. With their fuel exhausted, heavy stars begin a complex chain of events that lead to the final dramatic explosion. Their cores rapidly collapse, releasing an enormous amount of gravitational energy. This sudden burst of energy reverses the collapse and tosses most of the star's mass into space. The ejected material can travel as fast as 45 million miles per hour (72 million kilometers per hour).

#ExoMars-2016 to make deep-space maneuver tomorrow.
On July 28, 2016, half way between Earth and Mars, the Trace Gas Orbiter, TGO, is scheduled to fire its 424-newton main engine for around 30 minutes, changing the spacecraft's velocity by 326 meters per second and resulting in slightly lower speed for the ExoMars-2016 arrival at the Red Planet.

+Fraser Cain  You (or most likely one of so many moderators) have deleted my introduction message (with no links or videos included) with no reason when I have started already be welcome by community members. That was so weird that I have reported this community as "harassment and bulling"
My office just two minutes drive from local Google office. If this should happened again I would visit them for sure and discuss if this kind of harassment (without the reason) is acceptable by Google policies. I am sure it is not.

Mount Wilson boasts the world’s longest optical interferometer: the Center for High Angular Resolution Astronomy (CHARA) Array. The CHARA Array is resolving the surfaces of nearby stars, providing unprecedented glimpses of the Sun’s neighbours.
Mount Wilson Observatory, perched atop the San Gabriel Mountains outside Los Angeles, has been the site of some of the greatest expansions in human knowledge of the cosmos. It is here that, in 1924, Edwin Hubble proved the existence of galaxies be...

Hadley Rille on the Moon, seen by SMART-1

Copyright ESA/Space-X, Space Exploration Institute

This strangely meandering channel, carved on the Moon, is one of the most famous features on our nearest celestial neighbour. It shot to fame in July 1971 when the two astronauts of Apollo 15 drove their lunar rover to its very edge.

Known as Hadley Rille, the feature is named after the 18th century British mathematician and inventor John Hadley. In 1721, Hadley presented a telescope that used a non-spherical mirror to the Royal Society in London. Shaped as a parabola, the mirror avoided the aberration caused by a spherical mirror, and set the shape for all telescope mirrors to come.

Hadley Rille is thought to have been carved by an ancient lava flow, dating back just over 3 billion years to soon after the Moon formed. It stretches more than 120 km, up to 1500 m wide and more than 300 m deep in some places.

Hi,

M13 is one of the most prominent and best known globular clusters. Visible with binoculars in the constellation of Hercules, M13 is frequently one of the first objects found by curious sky gazers seeking celestials wonders beyond normal human vision. M13 is a colossal home to over 100,000 stars, spans over 150 light years across, lies over 20,000 light years distant, and is over 12 billion years old. At the 1974 dedication of Arecibo Observatory, a radio message about Earth was sent in the direction of M13. The featured image in HDR, taken through a small telescope, spans an angular size just larger than a full Moon, whereas the inset image, taken by Hubble Space Telescope, zooms in on the central 0.04 degrees.

Observing separate galaxies, their groups and clusters, we understand that the Universe is highly inhomogeneous on sufficiently small scales. At the same time, according to the cosmological principle, the Universe is supposed to be homogeneous and isotropic when viewed at a large enough scale. The natural question arises: what is this typical averaging scale, at which the cosmological principle comes into its own? The standard approach leads to the value ~ 370 Mpc, contradicting the fact of existence of the observed largest cosmic structures with Gpc dimensions. However, there is another suitable value in cosmology, which is 10 times larger at present, namely, the Yukawa range of gravitational interaction. Therefore, we can trust the cosmological principle starting from distances, which exceed ~ 3.7 Gpc, and then the contradiction associated with the Gpc structures may be removed.

NGC 6302 es una nebulosa planetaria bipolar en la constelación de Scorpius, el escorpión, también conocida como nebulosa del Insecto o nebulosa de la Mariposa. Al estar incluida en el Nuevo Catálogo General, este objeto es conocido al menos desde1888. El primer estudio conocido de NGC 6302 data de 1907 y fue llevado a cabo por Edward Emerson Barnard, quien dibujó y describió esta nebulosa.

A una distancia de 3400 años luz de la Tierra, NGC 6302 es una de las nebulosas planetarias más complejas que se conocen. Su espectro muestra que su estrella central es uno de los objetos más calientes del universo, con una temperatura superior a 200.000 K. No ha podido ser observada al estar rodeada de un denso disco ecuatorial compuesto de polvo y gas, que la oculta en todas las longitudes de onda. Este disco denso puede ser el responsable de que los flujos de la estrella formen una estructura bipolar.

La compleja morfología de la nebulosa puede aproximarse como bipolar con dos lóbulos principales, si bien hay evidencia de un segundo par de lóbulos que pueden provenir de un episodio previo de pérdida de masa. El lóbulo prominente, orientado en sentido norte-oeste, puede haberse formado hace unos 1900 años. A 1,71 minutos de arco del centro, la velocidad de expansión de este lóbulo es de 263 km/s, pero en la periferia del mismo la velocidad supera los 600 km/s. El borde oeste del lóbulo muestra características que sugieren una colisión con glóbulos de gas preexistentes que modificaron el flujo en esa región.

Junto a la Nebulosa de la Araña Roja (NGC 6537), es uno de los dos objetos en donde por vez primera se han encontrado carbonatos sin ninguna relación con el agua líquida. El descubrimiento (mediante elObservatorio Espacial Infrarrojo (ISO) de grandes cantidades de calcita y dolomita en NGC 6302, rompe la asociación automática entre estos minerales y el medio acuoso.
