New stars stir up a nebula


Welcome to the Daily Telescope .
At Ars Technica, we’re going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.
It’s March 12, and today’s photo comes from the James Webb Space Telescope.
Astronomers have long been fascinated by a nebula, NGC 604, in the relatively nearby Triangulum Galaxy.
That’s because this nebula contains about 200 of the hottest and largest types of stars, most of which are in the early stages of their lives.
Astronomers know of no other region in the Universe so densely packed with large stars as this nebula.
In this image, captured by the Near-Infrared Camera on the Webb telescope, there are brilliant reds and oranges.
Stellar winds from the brightest and hottest young stars have carved out these cavities, while ultraviolet radiation ionizes the surrounding gas.
The bright orange streaks in the Webb near-infrared image signify the presence of carbon-based molecules known as polycyclic aromatic hydrocarbons.

This is the Daily Telescope .. There is a bit too much pseudoscience and not enough science in the world, as well as a bit too much darkness. We’re going to let other magazines give you a daily horoscope instead. We’re going to go in a different direction here at Ars Technica, drawing inspiration from actual photographs of a universe full of wonder and stars.

Hi there, good morning. Today’s image, taken on March 12, was captured by the James Webb Space Telescope.

Nebula NGC 604 in the relatively nearby Triangulum Galaxy has long captivated astronomers. This is because, for the most part, the 200 stars in this nebula are young, massive stars that are among the hottest in the universe. More than 100 times the mass of the Sun is found in some of these stars. There is nowhere else in the universe that has as many massive stars crammed together as this nebula, according to astronomers.

These vivid reds and oranges were seen in this picture taken with the Webb telescope’s Near-Infrared Camera. According to astronomers, these colors mean what follows:.

The most striking features are bright red emission tendrils and clusters that radiate from what appear to be clearings or sizable bubbles in the nebula. The hottest and brightest young stars’ stellar winds have sculpted these cavities, and the surrounding gas has been ionized by UV radiation. An ethereal white and blue glow is the result of ionized hydrogen. Polycyclic aromatic hydrocarbons, which are carbon-based molecules, are indicated by the bright orange streaks in the Webb near-infrared image.

At most, the nebula is only 3.5 million years old.
