From Hubblecast, the unveiling of Hubble’s 23rd Anniversary image: a stunning new image of one of the most distinctive objects in our skies: the Horsehead Nebula. This image shows the nebula in a whole new light, capturing plumes of gas in the infrared and revealing a beautiful, delicate structure that is normally obscured by dust.
This year marks the 23rd year of observing for the Hubble Space Telescope. Alongside cutting-edge science, the orbiting observatory has produced countless stunning astronomical images. Some of the most striking and beautiful subjects of Hubble’s images have been nebulae — vast interstellar clouds of gas and dust.
This new Hubble image, captured and released to celebrate this milestone, shows part of the sky in the constellation of Orion (The Hunter). Rising like a giant seahorse from turbulent waves of dust and gas is the Horsehead Nebula, otherwise known as Barnard 33. The nebula formed from a collapsing interstellar cloud of material, and glows as it is illuminated by a nearby hot star [1].
The gas clouds surrounding the Horsehead have already dissipated, but the jutting pillar is made of stronger stuff — thick clumps of material — that is harder to erode. Astronomers estimate that the Horsehead formation Continue reading Horsehead Sculpted in Dust
