- They're not stars - Dagsavisen

– The first thing to rule out is the presence of a star in the Milky Way, says Matt Kaplan, assistant professor of physics at Illinois State University according to CNN.

The phenomenon, which looks like a question mark, was imaged by NASA’s James Webb Space Telescope. The telescope is used to learn more about the history of the universe, how galaxies and solar systems are formed and what kind of atmospheres exist on other planets. Launched in December of 2021, According to Ung Forskning.no.

The first images from the telescope appeared in July last year, and one can now be amazed at what the images show.

Question mark behind the question

One of the near infrared images released on July 26 of this year shows something that looks tantalizingly like a question mark. The image shows two young stars named Herbig-Haro 46/47. The star pair is located 1,470 light-years away from us, in the constellation Celite or Vela in Latin.

The two stars have been observed and studied by space and ground-based telescopes since the 1950s, but the highly sensitive Webb telescope made it possible to capture the most accurate and detailed image to date. A telescope can look far into space and give us sharp images of what lies beyond our reach. That’s why we can now see the glowing “question mark”.

She is not a star

– The two parts can be merged galaxies. Researcher Matt Kaplan says the top of the Question Mark may be a larger galaxy undergoing perturbation.

Because this phenomenon does not have the kind of ripples that stars get in images taken by the James Webb Observatory, Kaplan rules it out as stars. However, he says there are many different things this question mark could be about.

The Milky Way will merge with Andromeda

The object is located far from our neighboring galaxy, possibly billions of light-years away, says Christopher Brett, an education and outreach researcher at the Space Telescope Science Institute. this printer Physical geography.

His guess is also that the question mark is that two galaxies merged. He explains that this happens to galaxies many times during their lifetime.

– This also applies to our galaxy, the Milky Way. It will merge with Andromeda in about four billion years.
