Eta Carinae: The Great Eruption of a Massive Star

- Опубликовано: 24 янв 2022
- Eta Carinae, or Eta Car, is famous for a brilliant and unusual outburst, called the "Great Eruption", observed in the 1840s. This visualization presents the story of that event and examines the resulting multiwavelength emissions and three-dimensional structures surrounding Eta Car today.
Massive stars are known to have major outbursts. Eta Car, one of the most massive stars known, expelled about 10% of its mass in the Great Eruption, creating a small nebula, called the Homunculus Nebula, around it. Images taken in different wavelengths of light reveal different structures, each providing more information about the outbursts of Eta Car.
For this visualization, astronomers and artists have used NASA observations to model both the close-up and wide views of this massive and eruptive star. The Hubble Space Telescope and the Chandra X-ray Observatory have observed the nested layers of gas and dust around Eta Car using visible, ultraviolet, and x-ray light, as well as in the Hydrogen Alpha emission line. The Spitzer Space Telescope provides a larger view of the Carina Nebula, along with Eta Car’s dominant position within this star-forming region.
This visualization is presented by the AstroViz Project of NASA’s Universe of Learning. Viewers gain appreciation for how the observations from two centuries ago connect to the resulting structures seen today. Full 360-degree 3D views help to assemble a complete mental model that aids interpretation of the NASA observations. Eta Car serves as a notable example of the outbursts in the dying stages of massive stars.

Hi everyone, I'm the leader of the team that created this video. Thank you for watching, and I'll answer your questions about it as time permits.
That zoom in was almost like a spiritual experience. Truly awesome.
That is the best CGI yet of a star going though a time period that is exciting to see and understand and it is the real deal. I still find Hubble's Ultra Deep Field image as the most incredible.
who has watched mahadev's damru??❤
They likes Shiva daamru
How did I get here from a King Buffalo song.
It's absolutely dazzling. Thank you for the excellent model
Thank God this thing is far away from us.
I'm 55 been into astronomy 40+ years..eta c is my favourite neb.truly awesome....what's the webb..gonna show us....I can't wait...thank you so much🖖👍🙏
Awesome to. See my mighty gods hand at work
Fantastic production
Thank you. That was both intellectually and artistically satisfying, and adds to my sense of wonder of the cosmos.
Very cool! Nicely done on this one--short and sweet, with a lot of cool information. Eta Carina is utterly fascinating.
This is why we do science! I just hope that Eta Car blew itself up a long time ago, and that the light from the supernova will hit earth at any moment. I could die happy then. Thank you to all involved in making this, you are the true heroes of the universe.
Both the star and the video itself are amazing. Thank you.
Incredibly well done , beautiful images and also very interesting comments . I was glued to my screen for a moment .Thank you
Wow, that cgi of the blast was amazing, this is an awesome way of learning about our universe. Thanks so much.
Brilliant. Thank you.
Incredible, thank you One Love from Portugal.
Thank you for this
