Wolf-Rayet Nebula is a nebula which surrounds a Wolf-Rayet star. There are different types of WR-nebula, based on their formation mechanism: 1.HII regions 2.ejecta-type nebulae 3.wind-blown bubbles 4.neutral hydrogen voids and shells (may be associated gas). The nebula shown is a 'wind-blown bubbles' type.

SNR 0509-67.5 is the last gasp of a massive star snuffed out in a titanic explosion 400 years ago. In 2012, Hubble spied this 23-light-year-wide supernova blast wave expanding at speeds of 11 million miles per hour. It is located in a Milky Way satellite galaxy called the Large Magellanic Cloud, about 170,000 light-years from Earth (National Geographic)

'Soap Bubble Nebula' - This is one huge bubble... as large as our Solar System.

Red Giant Blows a Bubble

In the realm of theory, the first appearance of fractals in cosmology was likely with Andrei Linde’s "Eternally Existing Self-Reproducing Chaotic Inflationary Universe" theory, in 1986. In this theory, the evolution of a scalar field creates peaks that become nucleation points which cause inflating patches of space to develop into "bubble universes," making the universe fractal on the very largest scales. Is our universe a subset of a more infinite "Mandelbrot Set", repeating over and over?

Two artificial fish fins placed side-by-side and flapped in-phase with each another as water flows past the fins (flow direction is up). Small hydrogen bubbles (the white part of the image) allow for the wake of the fins to be visualized. The interaction of the fins creates two repeating patterns of swirling vortices known as vortex streets.

Dark matter observed for the first time

Even NASA cannot explain it. It’s best to gaze in wonder at the sliding rocks on this dry lake bed in Death Valley National Park. Racetrack Playa is almost completely flat, 2.5 miles from north to south and 1.25 miles from east to west, and covered with cracked mud. The rocks, some weighing hundreds of pounds, slide across the sediment, leaving furrows in their wakes, but no one has actually witnessed it.
