The results presented by Lockman suggest that, as some astronomers have predicted, the hot gas in the halo slowly cools and condenses
into hydrogen clouds along with wispy filaments that connect them.
Then, list 2 effects that would be expected upon substi - tuting an electron with a muon in a helium atom when mixed
into a hydrogen cloud.
Then, summarize the effects that would be expected upon subst - ituting an electron with a muon in a helium atom when mixed
into a hydrogen cloud.

Clumpiness begot more clumpiness, as gravity pulled more matter
into these dense regions, and
clouds of gas, composed mostly of
hydrogen atoms, began to assemble.
About 4.6 billion years ago, an enormous
cloud of
hydrogen gas and dust collapsed under its own weight, eventually flattening
into a disk called the solar nebula.
At the time our solar system formed about 4.6 billion years ago, only about 39 % of the
hydrogen and helium in our galaxy had collapsed
into clouds that then evolved
into stars, they say.
He and his colleagues slammed a beam of heavy
hydrogen atoms
into a
cloud composed of more heavy
hydrogen.
At the center of the
cloud, matter would pile up to densities and temperatures that (scientists later realized) were high enough to allow
hydrogen atoms to fuse
into helium.
Comets are surrounded by a huge
cloud of atomic
hydrogen because water (H2O) vaporizes from the icy nucleus, and solar ultraviolet light breaks it apart
into hydrogen and oxygen.
Supernova explosions blew these heavier elements
into interstellar space, where they mixed with
clouds of primordial
hydrogen and helium and were recycled
into subsequent generations of stars.
The shared
cloud of electrons indicated a transition
into a metallic state, making the
hydrogen shiny and electrically conductive.
The Calabash nebula (bottom left), illustrates what happens when high - speed winds of stellar gas (yellow) create shock waves as they ram
into clouds of interstellar
hydrogen and nitrogen (blue).
Under the
clouds of methane,
hydrogen and helium, the sky gradually turns
into liquid until it becomes a giant ocean of liquid chemicals.
The faint but enormous ionised
clouds visible in
hydrogen - alpha to the east of the CMa OB1 association hint at the structure of this enormous celestial river reaching
into the outer galaxy.
«However, as we penetrate deeper
into the Universe, and hence back to earlier times, the space between galaxies contains an increasing number of dark
clouds of
hydrogen which absorb this signal.»
Photo Source: S. Brunier; Design & Illustration: P. Vosteen (CC BY - ND) A team of astronomers has discovered what appears to be a grand exodus of more than 100
hydrogen clouds streaming away from the center of the Milky Way and heading
into intergalactic space.
This question stands because the
clouds are constantly being washed out by intense radiation, hence cracking the
hydrogen molecules
into atoms.
Observations of SN 2006gy with optical telescopes have determined that the bulk of supernova's debris is moving outward at around 15 million kilometers (or 9.3 million miles) per hour (kph or mph)
into a circumstellar nebula or «
cloud» of
hydrogen gas that is coasting along at a leisurely 700,000 kph (or 430,000 mph).
