Astronomers use the very large telescope interferometer to (VLTI) from European Southern Hemisphere Observatory (ESO) Find and take pictures Big star WOH G64 in “Galaxy Cloud Magellanic Cloud” which is a dwarf satellite of the Milky Way galaxy
A team of astronomers has revealed that they have known this star for some time. and he called it a “big star” because it is 2,000 times bigger than the sun. WOH G64 It is located in the Large Magellanic Cloud galaxy. and is about 160,000 light years away from Earth.
Thanks to the power of the VLTI telescope, these distant stars can be seen in detail, revealing the gas and dust around them. the flow of these materials This indicates that WOH G64 is dying in the final stages of its star’s life. This will lead to a massive supernova explosion. This data is consistent with a sharp decline in the star’s brightness over the past ten years.
Keiichi Ohnaka, astronomer from Andres Bello University The leader of the team that studies this star It is said to be the first time he has successfully photographed a dying star in an extragalactic galaxy outside the Milky Way. They also found an egg-shaped cocoon that closely surrounds the star. And we’re excited because this could involve sending stuff out of the star. who dies violently before the supernova explosion
Astronomers around the world are now able to take pictures of stars in the Milky Way galaxy. But to be able to take pictures of stars outside the galaxy at such a level of detail It still takes time to develop technology in the future. Because the distance between each galaxy is very long. And the universe is very wide.
for “Galaxy Cloud Magellanic Cloud”It is a satellite galaxy of the Milky Way. Located about 160,000 light years away from us, it is the third closest galaxy to the Milky Way. It has an elliptical dwarf galaxy. by the Great Dog Dwarf Galaxy It is near the center of the Milky Way galaxy. The Magellanic Cloud has an equivalent mass of about 10 billion times the mass of the Sun. Its mass is estimated to be about 1/10 the mass of the Milky Way. The Magellanic Cloud is the 4th largest galaxy in the Local Group.It contains the Andromeda galaxy, the Milky Way, and the Triangulum. They are the 1st, 2nd, and 3rd largest galaxies, respectively.

## Interview: A Star’s Last Breath
**Host:** Welcome back to World Today News. Today, we’re delving into the cosmos to discuss the incredible feat of capturing an image of a dying star outside our own galaxy. We’re joined by Dr. Emily Carter, an astrophysicist specializing in stellar evolution, and Dr. Alex Garcia, an astronomer working on cutting-edge telescope technology. Welcome both.
**[Theme 1: The Discovery]**
**Host:** Dr. Carter, can you tell us about WOH G64, the star that’s captured the attention of astronomers worldwide?
**Dr. Carter:** WOH G64 is a red supergiant star, a behemoth roughly 2,000 times the size of our own Sun. It’s located in the Large Magellanic Cloud, a relatively nearby galaxy. Though it’s been known for some time, the recent images captured by the VLTI have given us an unprecedented look at this star’s final stages.
**Host:** Dr. Garcia, can you explain how the VLTI, the Very Large Telescope Interferometer, allowed for this groundbreaking image?
**Dr. Garcia**: The VLTI is a remarkable instrument combining the light from four separate telescopes, effectively creating a virtual telescope with a much larger collecting area. This allows it to see incredibly fine details, even in objects as distant as WOH G64. This technology pushes the boundaries of what we can observe in the universe.
**[Theme 2: The Lifecycle of Stars]**
**Host:** Dr. Carter, what can this image of WOH G64 teach us about the lifecycle of stars?
**Dr. Carter:** Stars like WOH G64 go through a spectacular cycle. They burn through their fuel, expanding and cooling, eventually leading to a dramatic supernova explosion. These images not only confirm previous observations about WOH G64’s decline in brightness, but also show the fascinating gas and dust structures surrounding it, possibly material ejected before its final explosion.
**Host:** This image seems to confirm what we already suspected about WOH G64’s fate. Can you elaborate on what we now know about its future?
**Dr. Carter:** Based on the observations, we believe WOH G64 is in its final stages. It will likely undergo a supernova explosion in the not-too-distant future, unloading a massive amount of energy and raw materials back into the cosmos, enriching the interstellar medium
**[Theme 3: The Future of Astronomy]**
**Host:** Dr. Garcia, what are the implications of being able to capture such detailed images from outside our own galaxy?
**Dr. Garcia**: This is just the beginning. Technology like the VLTI allows us to peer further into the universe, observing stellar phenomena that were previously obscured. By studying these objects, we gain deeper insights into the vastness of the cosmos and the processes governing star formation and death.
**Host:** Looking ahead, Dr. Garcia, what advancements do you see in telescope technology that will allow us to uncover even more mysteries of the universe?
**Dr. Garcia**: There are exciting developments ongoing. We’re constantly working on improving resolution and sensitivity, aiming to collect even more data from incredibly distant objects. The future of astronomy lies in pushing these technological boundaries further, allowing us to unravel the secrets of the universe.
**Host**: It’s indeed an incredibly exciting time for astronomy. 1Turning our gaze to the stars provides endless wonder and the potential for groundbreaking discoveries. Thank you both for joining us today.
