The James Webb Space Telescope just captured the most detailed images yet of a flowing mane. Horsehead Nebulaa dense, distant cloud of gaseous particles that serves as a breeding ground for new stars.

“These observations reveal the tip of the horse’s mane, or edge, of this iconic nebula,” a NASA spokesperson said in an official press release, “reflecting the complexity of the region with unprecedented spatial resolution.”

The Clearest Infrared Images

These observations, made by an international team of astronomers, reveal the complexity of this cosmic object with unprecedented spatial resolution and show part of the nebula in light infrared eyes from Webb.

This nebula is located approximately 1300 light years from Earth, in the constellation Orion (the Hunter). The Horsehead Nebula is also known as Barnard 33and formed from turbulent waves of dust and gas on the western side of the Orion B molecular cloud.

Stars sneeze too

It was first recorded in 1888 by an American astronomer of British origin. Williamina Fleming at the Harvard University Observatory. An astronomer who was an assistant at the observatory identified this intriguing structure on a photographic plate taken through a telescope. The nebula is part of a much larger complex in Orion. includes the Orion Nebula (M42), one of the brightest nebulae visible to the naked eye.

New images from JWST, the most powerful telescope ever to orbit our planet, show the nebula as turbulent waves of gas rising from the western side of the planet. Orion Molecular Cloud Complex, and is about 3.5 light years across. It is considered one of the best objects in the sky for studying the interaction of radiation with interstellar matter.

To capture the impressive images, astronomers used a near-infrared camera. (NIRKam) and mid-infrared instrument (MIRI) James Webb, which capture photons emitted in the infrared spectrum of light as massive young stars heat up regions of the gas cloud; something that helps scientists understand the chemical and physical processes that allow interstellar matter to evolve and stars to form.

One of the new infrared images taken by the James Webb Telescope shows a region of gas made up of cold hydrogen molecules with sharp color separation. (blue) turns into charged “ionized” hydrogen atoms (red).

Another image shows mid-infrared light in great detail as this heat is emitted by dusty quartz-like silicate particles and hydrocarbon molecules that form deep space clouds in the mane of the Horsehead Nebula.

“As ultraviolet light evaporates a dust cloud, dust particles are drawn out of the cloud and carried along with the heated gas,” NASA James Webb said in a study published in the journal. Astronomy and astrophysics. “Webb discovered a network of small features that track this movement. The observations also allowed astronomers to explore how dust blocks and emits light, and better understand the multidimensional shape of the nebula.”

In the future, astronomers intend to study spectroscopic data obtained from the nebula to demonstrate the evolution of the physical and chemical properties of the material observed throughout the nebula. These images show that JWST is poised to make an impact on this research.

The ultimate fate of this nebula is its extinction. although, according to astronomers, the Horsehead Nebula has about five million years before it falls apart. The horse-shaped structure that makes this nebula so distinctive resulted from the erosion of lighter gas, leaving a thick plume of dense gas and dust that is more difficult to destroy. But this card won’t last forever. Webb’s new view focuses on the illuminated edge of the top of the nebula’s distinctive structure of dust and gas, offering a glimpse into its eventual future.

The $10 billion James Webb Telescope was built to observe the first galaxies born in the early Universe. more than 13.5 billion years ago, observe the sources of stars, exoplanets and even the moons and planets of our solar system. It is the largest and most powerful orbiting space telescope in the world. Webb’s infrared gaze will continue to illuminate the mysteries of the universe, allowing us to appreciate the wonders that surround us and deepen our understanding of the vast conditions facing our planet.
