Explanation:
These wisps of gas are all that remain visible of a
Milky Way star.
Many thousands of years ago that star exploded in a
supernova leaving the
Veil Nebula,
pictured above.
At the time, the
expanding cloud
was likely as bright as a crescent
Moon toward the
constellation of
Cygnus,
visible for weeks to people living at the dawn of
recorded history.
The
supernova remnant lies about 1400
light-years away and covers over five times the size of the
full Moon.
The above image of the
Veil
was made clearer by digitally dimming stars in the frame.
The bright wisp at the top is known as the
Witch's Broom Nebula
and can be seen with a small telescope.
The Veil Nebula is also known as the
Cygnus Loop.
