See a stunning image of the Orion nebula stellar nursery

Orion is one of the most recognizable constellations in the night sky, and within the constellation is a beautiful nebula that is a busy region of star formation. A stunning image of the Orion nebula was recently released by NASA, showing the delicate structures of dust and gas that make up this stellar nursery.

The structure of the nebula is formed by large stars that give off radiation that affects the clouds of dust. “Two enormous caverns that dominate the cloud were carved out by giant stars (unseen in this image) that can release up to a million times more light than our sun,” NASA explains. “All that radiation breaks apart dust grains there, helping to create the pair of cavities. Much of the remaining dust is swept away by winds from stars or when the stars die explosive deaths as supernovae.”

This infrared image of the Orion Nebula features plenty of dust but no stars. In these infrared wavelengths, it’s possible to see hot spots where new stars are forming, while unseen bright, massive stars have carved out caverns of empty space.

The image combines data from the now-retired Spitzer Space Telescope and the current Wide-Field Infrared Survey Explorer (WISE), now known as NEOWISE. Spitzer, which retired in 2020, looked in the infrared wavelength to peer through dust and see the interior structure of objects like nebulae. As for NEOWISE, the telescope now watches the sky for near-Earth objects like asteroids, but it also produces all-sky maps showing how the sky is changing over time.

Additional data for the image came from the European Space Agency’s now-retired Herschel Space Telescope, which added data on the far-infrared and microwave wavelengths, which is shown in red and green. In the image of the Orion nebula, areas of blue light represent regions of warm dust, while areas of red represent cooler dust. Red areas are as cold as minus 440 Fahrenheit (minus 260 Celsius), and tend to be around the outer edge of the nebula, while in the center of the nebula, the dust is hotter due to stars forming there.

Stars will continue to form in the region as the dust and gas clumps together to form knots, which attract more material until they eventually collapse under gravity to form a the heart of a new star.

See a stunning field of galaxies captured by James Webb Space Telescope
A crowded field of galaxies throngs this Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope, along with bright stars crowned with Webb’s signature six-pointed diffraction spikes. The large spiral galaxy at the base of this image is accompanied by a profusion of smaller, more distant galaxies which range from fully-fledged spirals to mere bright smudges. Named LEDA 2046648, it is situated a little over a billion light-years from Earth, in the constellation Hercules.

Stunning images from the James Webb Space Telescope continue to entrance, and recently the researchers using the telescope have shared a gorgeous image of a field of galaxies as part of the Webb Picture of the Month collection.

The image shows a spattering of different background galaxies, while the foreground shows bright individual stars and a bright spiral galaxy at the bottom called LEDA 2046648. Located around a billion light-years from Earth, this galaxy is relatively much closer to us than the far-off background galaxies which is why it is so prominent in the image.

Stars sparkle in Orion Nebula in this week’s gorgeous Hubble image
The bright variable star V 372 Orionis takes center stage in this image from the NASA/ESA Hubble Space Telescope, which has also captured a smaller companion star in the upper left of this image. Both stars lie in the Orion Nebula, a colossal region of star formation roughly 1,450 light-years from Earth.

The Hubble Space Telescope is one of the great achievements in modern astronomy, still producing stunning and scientifically valuable images after more than 30 years of operation. Each week, scientists working with Hubble share an image captured by the telescope, and this week's image shows a snippet of a famous nebula along with two bright stars.

The image shows a part of the beautiful Orion Nebula, featuring the bright star V 372 Orionis just to the lower-right of the center along with a companion star to the top-left. The Orion Nebula is located 1,450 light-years away and is famous as a stellar nursery where large numbers of new stars are born.
