Insanely Detailed Webb Image of the Horsehead Nebula

The NASA/ESA/CSA James Webb Space Telescope has captured the sharpest infrared images to date of one of the most distinctive objects in our skies, the Horsehead Nebula. The observations show a part of the iconic nebula in a whole new light, capturing its complexity with unprecedented spatial resolution.

Few space images are as iconic as those of the Horsehead Nebula. Its shape makes it instantly recognizable. Over the decades, a number of telescopes have captured its image, turning it into a sort of test case for a telescope’s power.

The JWST has them all beat.

New Images Reveal the Magnetic Fields in the Horsehead Nebula

Located near the summit of Maunakea, Hawaii, the 15-meter (~49 ft) James Clerk Maxwell Telescope (JCMT) at the East Asia Observatory (EAO) is the largest telescope in the world designed to operate exclusively in the submillimetre-wavelength. In 2018, Molokai’i High School alumna Mallory Go was awarded time with the JCMT under the Maunakea Scholars program. With the assistance of EAO astronomer Dr. Harriet Parsons, Go obtained unique images of the Horsehead Nebula in polarized light, which revealed the nebula’s magnetic fields.

A New Image Reveals Orion’s Flame Nebula in Infrared

Do not let the image and the name of the depicted cosmic object fool you! What you see in this picture is not a wildfire, but the Flame Nebula and its surroundings captured in radio waves. The Flame Nebula is the large feature on the left half of the central, yellow rectangle. The smaller feature on the right is the reflection nebula NGC 2023. To the top right of NGC 2023, the iconic Horsehead Nebula seems to emerge heroically from the “flames”. The three objects are part of the Orion cloud, a giant gas structure located between 1300 and 1600 light-years away. The different colours indicate the velocity of the gas. The Flame Nebula and its surroundings are moving away from us, with the red clouds in the background receding faster than the yellow ones in the foreground. The image in the rectangle is based on observations conducted with the SuperCam instrument on the ESO-operated Atacama Pathfinder Experiment (APEX) on Chile’s Chajnantor Plateau. The background image was taken in infrared light with ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA) at the Paranal Observatory in Chile.

The ESO has released some stunning new images of Orion’s Flame Nebula. They’re from a few years ago but are newly processed as part of the Orion cloud complex study. The images have led to discoveries in the often-observed Orion cloud complex.

Stunning 3D Tours of Two Well-Known Nebulae

Two videos recently released by the Hubble team take us on a tour of two famous and intriguing cosmic objects: the stellar wind-blown “celestial snow angel” Sharpless 2-106 and the uncannily equine Horsehead Nebula, imaged in infrared wavelengths by the HST.

Using Hubble imagery complemented with data from the Subaru Infrared Telescope and ESO’s Visible and Infrared Survey Telescope for Astronomy — VISTA, for short — the videos show us an approximation of the three-dimensional structures of these objects relative to the stars surrounding them, providing a perspective otherwise impossible from our viewpoint on Earth.

The stellar nursery Sharpless 2-106 is above; hop on the Horsehead Nebula tour below:

Astrophoto: Gorgeous Panorama of the Orion & Horsehead Nebulae and Orion’s Belt

A panoramic view of the Great Orion Nebula and the Horsehead Nebula including the very familiar three bright stars of Orion's belt. This was captured in January, February and early March 2014 over 8 nights. Credit and copyright: Terry Hancock.

Astrophotographer Terry Hancock has been working on this for several weeks and the results are fabulous. This panoramic view of the Orion region includes two of the most recognizable objects in this constellation — the Orion Nebula and the Horsehead Nebula. It also takes a look at the three bright stars of Orion’s belt Alnitak (to the left of the image), Alnilam and Mintaka. Additionally, it shows part of the Orion molecular cloud.

Wow!

More info on this image from Terry:
