170 YEARS AGO,(from 2018) ETA CARINAE ERUPTED DRAMATICALLY. ASTRONOMERS NOW THINK THEY KNOW WHY

Superstar Eta Carinae Wont Die! 'The Death Star'

#EtaCarinae, the most luminous and massive stellar system within 10,000 light-years of Earth, is known for its surprising behavior, erupting twice in the 19th century for reasons scientists still don't understand. A long-term study led by astronomers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, used NASA satellites, ground-based telescopes and theoretical modeling to produce the most comprehensive picture of Eta Carinae to date. New findings include #HubbleSpaceTelescope images that show decade-old shells of ionized gas racing away from the largest star at a million miles an hour, #MilkywayGalaxy Narrated by BuzWeaver: :Support Eta Carinae Teespring: Music: Orange from YT Audio library

Weird X-Rays: What Happens When Eta Carinae�s Massive Stars Get Close?

While the stars appear unchanging when you take a quick look at the night sky,
there is so much variability out there that astronomers will be busy forever. One prominent example is Eta Carinae,
a star system that erupted in the 19th century for about 20 years, becoming one of the brightest stars you could see in the night sky.
It�s so volatile that it�s a high candidate for a supernova.

Raging Stellar Winds Collide in Eta Carinae Star System | Video


: More space news and info at - astronomers have used the Very Large Telescope Interferometer to image the Eta Carinae star system in the greatest detail ever achieved. They found new and unexpected structures within the binary system, including in the area between the two stars where extremely high velocity stellar winds are colliding. These new insights into this enigmatic star system could lead to a better understanding of the evolution of very massive stars. This colossal binary system consists of two massive stars orbiting each other and is very active, producing stellar winds which travel at velocities of up to ten million kilometers per hour. The zone between the two stars where the winds from each collide is very turbulent, but until now it could not be studied. The power of the Eta Carinae binary pair creates dramatic phenomena. A “Great Eruption” in the system was observed by astronomers in the 1830s. We now know that this was caused by the larger star of the pair expelling huge amounts of gas and dust in a short amount of time, which led to the distinctive lobes - known as the Homunculus Nebula - that we see in the system today. The combined effect of the two stellar winds as they smash into each other at extreme speeds is to create temperatures of millions of degrees and intense deluges of X-ray radiation. The above video zooms in on the massive star system Eta Carinae, located in the Carina Nebula. During the zoom the Homunculus Nebula and finally the violent surroundings of Eta Carinae becomes visible. Lastly, an artist's animation zooms in from outside of the Homunculus Nebula, revealing the system's two massive orbiting stars.

Will Eta Carinae Destroy Life on Earth?


Eta Carinae is located 7,500 light-years away. It is a system of two stars 100 times massive and 5 million times more brighter than our sun. According to astronomers Eta Carinae is about to explode into a hypernova. When that happens it will light up our night sky . It will be the first hypernova we've ever seen. Luckily, we're too far for it's radiation to affect us so we will be totally safe from it.

Astronomers stunned again by Eta Carinae – the star that will not die











Eta Carinae the Enigmatic Explosive Star Probed by NASA NUSTAR


Eta Carinae, is a well known massive, luminous star system located about 7,500 light-years away from the Earth. It is in the southern constellation of Carina, and produced an outburst in the 19th century making it the second-brightest star in the sky. Since then, Eta Car has been well studied but still it holds fascination for astronomers studying explosive star systems. It has two massive stars that come very close to each other every 5.5 years. The system has intense outflows which accelerate charged particles to an amazing speed and can produce energy bursts that can be observed by many telescopes. Studies with the NuSTAR space telescope recently have helped characterize the outbursts and the types of particles sent our way Join Tony Darnell and Carol Christian during Afternoon Astronomy Coffee on July 12 at 3PM Eastern time as they discuss with the investigators, including Kenji Hamaguchi of Goddard Space Flight Center (GSFC) and U. of Maryland (UMBC) and Michael Corcoran of GSFC and Catholic University and Christopher Russell (Pontificia Universidad Católica de Chile) and how they probed Eta Car with NuSTAR to understand the system, and they will describe this interesting NASA mission that probes the high energy universe.
