Large-scale structures are also visible, such as large clouds of dust and gas where stars are forming at rapid rates.
This says that the exploding material (whatever it may be) races outwards and collides with interstellar dust and gas, producing radiation.
By observing the cloud of dust and gas kicked up by each impact, scientists knew they could obtain valuable data about the Moon's composition.

As a comet gets closer to the sun, the sun's heat causes these elements to melt, spewing out dust and gas in a brilliant tail.
Because of the large amount of dust and gas in such galaxies, it is difficult to peer deep into their central regions with optical telescopes.
It already has a 64, 000km-long tail of dust and gas that will become visible to the naked eye later in the year - a trail scientists will study closely.
Herschel's view of RCW 120, a bubble of gas and dust in space around a massive star.
It will study the clouds of gas and dust that go into making stars and planets.
It is obscured by vast clouds of gas and dust in the constellation of Sagittarius.
However, X-rays emanating from the galactic core can penetrate the veil of gas and dust.
Herschel will be remembered as the telescope that produced great vistas of gas and dust, as here in the constellation of Cygnus.
When the explosion occurred, the ejected material would have traveled unimpeded by gas and dust and spread out quickly.
FORBES: NASA Reveals the Mysteries of the First Known Supernova
This technology has allowed Herschel to study the processes at play as large clouds of gas and dust collapse to form new stars.
The light from such giants blows away the outer gas and dust of their neighbours, leaving nothing to form planets.
According to Tomsick, the radio emission from the gas and dust surrounding the star make those pulses more difficult to read.

There may not exist in today's Universe places that have sufficient supplies of gas and dust to feed ever more massive stars.
Instead, gas and dust would simply have orbited around our star without moving inward, creating a so-called "dead zone" in the disk.

Gas and dust would have piled up in the dead zone, increasing its density and causing it to heat up by gravitational compression.

Ordinarily, there should come a point where the pressure from all the radiation emitted by a stellar behemoth pushes back against any further infall of gas and dust.
It is thought that debris from the explosion slams into the gas and dust surrounding whatever it was that blew up, and that this collision generates gamma rays.
Here, looking towards the centre of the Milky Way, it spies a ribbon of cold gas and dust that is more than 600 light-years across and which appears to be twisted.
By comparison, meteors of the type that hit Russia originate at the earliest reaches of time in the disk of gas and dust that swirled around the early sun.
Stars are the result of the gravitational collapse of huge clouds of gas and dust, whereas planets are thought to evolve by the accretion of the material left over from such collapses, which forms a rotating disc around the newly created star.
Mr. EICHER: We can't really understand the solar system and how it got going unless we can really understand the origins and the conditions that happened when the solar nebula, this cloud of gas and dust, contracted down and the star turned on and the planets got going.
Collisions between the cosmic rays and the slower-moving protons that exist in the gas and the dust around a supernova should produce subatomic particles called neutral pions.
Mining experts said it could have been a methane gas explosion, a coal dust explosion, or a combination of both.
In 2008, while automakers plodded along with the same old gas-guzzling models as the price at the pump hit record highs, American consumers scrambled for more fuel-efficient vehicles and left the gas-guzzlers to collect dust on the showroom floor.
FORBES: Auto Industry And U.S. Economy Will Benefit Under New Mileage Standards
The first kind, the chunks, could be anything in size from dust grains, up through rocks and asteroids, to brown dwarfs (condensed lumps of gas not quite heavy enough to be stars).
