This interstellar apparition has a surprisingly familiar shape. Known as
the Bubble Nebula, the cosmic circle is formed from the wind of a
massive star.
This spectactular photo was taken by astrophotographer Jaspal Chadha from London. Chadha used a Altair Astro RC 250TT Scope.
Approximately
6 light-years wide, NGC 7635 is located roughly 7,100 light-years from
Earth in the constellation Cassiopeia. A light-year is the distance
light travels in one year, or about 6 trillion miles (10 trillion
kilometers). Intense radiation and stellar winds from a nearby star
created this delicate-looking bubble, surrounded by red, hot gas.
Astronomers using ESO’s Very Large Telescope in Chile have captured this image of planetary nebula Abell 33.
The hand might look like an X-ray from the doctor's office, but it is
actually a cloud of material ejected from a star that exploded. NASA's
NuSTAR spacecraft has imaged the structure in high-energy X-rays for the
first time, shown in blue. Lower-energy X-ray light previously detected
by NASA's Chandra X-ray Observatory is shown in green and red.
This picture of the nebula around a rare yellow hypergiant star called
IRAS 17163-3907 is the best ever taken of a star in this class and shows
for the first time a huge dusty double shell surrounding the central
hypergiant. The star and its shells resemble an egg white around a yolky
centre, leading astronomers to nickname the object the Fried Egg
Nebula.
