NASA's Hubble Space Telescope has snapped a spectacular new image of an iconic nebula to celebrate its 23 years of peering deep into the heavens.
The Hubble observatory, which launched on April 24, 1990, captured theHorsehead Nebula in infrared light, peering through obscuring veils of dust to reveal the object's hidden features.
"The result is a rather ethereal and fragile-looking structure, made of delicate folds of gas -- very different to the nebula's appearance in visible light," mission officials wrote in an image description today (April 19). The new observations allowed astronomers to create a dazzling video of the Horsehead Nebula based on Hubble's photos.
The Horsehead Nebula, also known as Barnard 33, is located about 1,500 light-years from Earth in the constellation Orion (The Hunter). The Horsehead is a huge interstellar cloud of gas and dust, like other nebulae, and the light from a nearby star gives it a beautiful glow.
The object is a popular observing target, and Hubble has taken numerous Horsehead photos over the years -- including in 2001, to celebrate the telescope's 11-year anniversary.
We hope anyone hurt/affected by the tragedy today can be at peace and safe.
