The first close-up photograph of a star outside the Milky Way has been taken by astronomers.
The WOH G64 star is 160,000 light years from Earth and the new image shows it in the last stages before becoming a supernova.
“For the first time, we have succeeded in taking a zoomed-in image of a dying star in a galaxy outside our own Milky Way,” said astrophysicist and lead author Keiichi Ohnaka.
The photograph shows a bright oval at the centre and a dusty cocoon shrouding the star. The fainter elliptical ring seen around it could be the inner rim of a dusty torus but the team behind the work published in Astronomy and Astrophysics on Thursday said more observations were needed to confirm that.
“We discovered an egg-shaped cocoon closely surrounding the star,” said Prof Ohnaka of Universidad Andres Bello in Chile. "We are excited because this may be related to the drastic ejection of material from the dying star before a supernova explosion."
The team believes the cocoon’s egg shape could be explained by either the star emitting gas or the influence of an as-yet undiscovered companion star.
The star is part of the Large Magellanic Cloud, one of the small galaxies that orbits the Milky Way.
It was photographed by the European Southern Observatory’s so-called very large telescope interferometer and the new observations reveal a star puffing out gas and dust.
Astronomers have taken more than 20 close-up images of stars inside the Milky Way but this was a step further in complexity and the team had to wait until the technology was available. In 2005 and again in 2007, the team had used telescopes in the Atacama Desert, Chile to learn about the star but a photograph was not possible until a new imaging system called Gravity was developed.
“This star is one of the most extreme of its kind and any drastic change may bring it closer to an explosive end,” said co-author Jacco van Loon, from the Keele University in the UK.
In the final life stages, "red supergiant" stars such as the one photographed shed outer layers of gas and dust in a process that can last thousands of years.
Astronomers have known about this star for decades and called it the "behemoth star". With a size about 2,000 times that of the Sun, WOH G64 is classified as a red supergiant.

10 tips for entry-level job seekers
- Have an up-to-date, professional LinkedIn profile. If you don’t have a LinkedIn account, set one up today. Avoid poor-quality profile pictures with distracting backgrounds. Include a professional summary and begin to grow your network.
- Keep track of the job trends in your sector through the news. Apply for job alerts at your dream organisations and the types of jobs you want – LinkedIn uses AI to share similar relevant jobs based on your selections.
- Double check that you’ve highlighted relevant skills on your resume and LinkedIn profile.
- For most entry-level jobs, your resume will first be filtered by an applicant tracking system for keywords. Look closely at the description of the job you are applying for and mirror the language as much as possible (while being honest and accurate about your skills and experience).
- Keep your CV professional and in a simple format – make sure you tailor your cover letter and application to the company and role.
- Go online and look for details on job specifications for your target position. Make a list of skills required and set yourself some learning goals to tick off all the necessary skills one by one.
- Don’t be afraid to reach outside your immediate friends and family to other acquaintances and let them know you are looking for new opportunities.
- Make sure you’ve set your LinkedIn profile to signal that you are “open to opportunities”. Also be sure to use LinkedIn to search for people who are still actively hiring by searching for those that have the headline “I’m hiring” or “We’re hiring” in their profile.
- Prepare for online interviews using mock interview tools. Even before landing interviews, it can be useful to start practising.
- Be professional and patient. Always be professional with whoever you are interacting with throughout your search process, this will be remembered. You need to be patient, dedicated and not give up on your search. Candidates need to make sure they are following up appropriately for roles they have applied.
