What a Star About to Go Supernova Looks Like

No, this isn't a distant view of the

. This nebula with a giant star at its center is known as SBW2007, located in the Carina Nebula. Astronomers say it has striking similarities to a star that went supernova back in 1987,

SN 1987A

. Both stars had identical rings of the same size and age, which were travelling at similar speeds; both were located in similar HII regions; and they had the same brightness. We didn't have the telescopic firepower back before 1987 like we do now, so we don't have a closeup view of how SN 1987A looked before it exploded, but astonomers think SBW2007 is a snapshot of SN1987a's appearance, pre-supernova.

Of course, no one can predict when a star will go supernova, and since SBW2007 is 20,000 light-years away, we don't have any worries about it causing any problems here on Earth. But astronomers are certainly hoping they'll have the chance to watch it happen.

SN 1987A is the closest supernova to that we've been able to study since the invention of the telescope and it has provided scientists with good opportunities to study the physical processes of an exploding star.

She is currently retired from daily writing, but worked at Universe Today for 20 years as a writer and editor. She also contributed articles to The Planetary Society, Ad Astra (National Space Society), New Scientist and many other online outlets.

Her 2019 book, "Eight Years to the Moon: The History of the Apollo Missions,” shares the untold stories of engineers and scientists who worked behind the scenes to make the Apollo program so successful, despite the daunting odds against it. Her first book “Incredible Stories From Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos” (2016) tells the stories of 37 scientists and engineers that work on several current NASA robotic missions to explore the solar system and beyond.

Nancy is also a NASA/JPL Solar System Ambassador, and through this program, she has the opportunity to share her passion of space and astronomy with children and adults through presentations and programs. Nancy's personal website is nancyatkinson.com
