Astronomers used Hubble’s Wide Field Camera 3 to probe the Homunculus nebula in ultraviolet light. They uncovered the glow of magnesium embedded in warm gas (shown in blue) in places they had not seen it before. The luminous magnesium resides in the space between the dusty bipolar bubbles and the outer shock-heated nitrogen-rich filaments (shown in red). The streaks visible in the blue region outside --> the lower-left lobe are a striking feature of the image. These streaks are created when the star’s light rays poke through the dust clumps scattered along the bubble’s surface. Wherever the ultraviolet light strikes the dense dust, it leaves a long, thin shadow that extends beyond the lobe into the surrounding gas. Image Credit: NASA, ESA, N.

GIANT STAR YIELDS NEW CLUES ABOUT TURBULENT LIFE This Hubble Space Telescope image of the giant, petulant star Eta Carinae is yielding new surprises. Telescopes such as Hubble have monitored the super-massive star for more than two decades. The star, the largest member of a double-star system, has been prone to violent outbursts, including an episode in the 1840s during which ejected material formed the bipolar bubbles seen here. Now, using Hubble's Wide Field Camera 3 to probe the nebula in ultraviolet light, astronomers have uncovered the glow of magnesium embedded in warm gas (shown in blue) in places they had not seen it before. The luminous magnesium resides in the space between the dusty bipolar bubbles and the outer shock-heated nitrogen-rich filaments (shown in red). The streaks visible in the blue region outside the lower-left lobe are a striking feature in the image. These streaks are created when the star's light rays poke through the dust clumps scattered along the bubble's surface. Wherever the ultraviolet light strikes the dense dust, it leaves a long, thin shadow that extends beyond the lobe into the surrounding gas. Eta Carinae resides 7,500 light-years away.

In the mid-1800s, mariners sailing the southern seas navigated at night by a brilliant star in the constellation Carina. The star, named Eta Carinae, was the second brightest star in the sky for more than a decade. Those mariners could hardly have imagined that by the mid-1860s the brilliant orb would no longer be visible. Eta Carinae was enveloped by a cloud of dust ejected during a violent outburst named “The Great Eruption. Because of Eta Carinae's violent history, astronomers have kept watch over its activities. Although Hubble has monitored the volatile superstar for 25 years, it still is uncovering new revelations. Using Hubble to map the ultraviolet-light glow of magnesium embedded in warm gas, astronomers were surprised to discover the gas in places they had not seen it before.

This rather garish picture is a unique three-dimensional image of the star Eta Carinae, with its twin lobes and equatorial disk of expanding dust and gas. To see the 3D structure the image must be viewed through colour 3D glasses with the left eye looking through a red filtered lens, and right eye looking through ablue filtered lens. Not likely you have a pair on hand, but it’s kind of cool anyway. Image Credit: Jon Morse (University of Colorado), Kris Davidson (University of Minnesota), and NASA/ESA

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.

: 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.

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.

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.

In addition to being one of the most beautiful and frequently photographed objects in the night sky, Eta Carinae also has also had the honor of being one of the sky’s most luminous stars for over a century and a half. In addition, it has been a scientific curiosity since its giant ejected nebula (Homunculus) contains information about its parent star.

An international team of astronomers has developed a 3D model of a giant cloud ejected by the massive binary system Eta Carinae during its 19th century outburst. Eta Carinae lies about 7,500 light-years away in the southern constellation of Carina and is one of the most massive binary systems astronomers can study in detail. The smaller star is about 30 times the mass of the sun and may be as much as a million times more luminous. The primary star contains about 90 solar masses and emits 5 million times the sun's energy output. Both stars are fated to end their lives in spectacular supernova explosions. Between 1838 and 1845, Eta Carinae underwent a period of unusual variability during which it briefly outshone Canopus, normally the second-brightest star. As a part of this event, which astronomers call the Great Eruption, a gaseous shell containing at least 10 and perhaps as much as 40 times the sun's mass was shot into space. This material forms a twin-lobed dust-filled cloud known as the Homunculus Nebula, which is now about a light-year long and continues to expand at more than 1.3 million mph (2.1 million km/h). Using the European Southern Observatory's Very Large Telescope and its X-Shooter spectrograph, the team imaged near-infrared, visible and ultraviolet wavelengths along 92 separate swaths across the nebula, making the most complete spectral map to date. The researchers have used the spatial and velocity information provided by this data to create the first high-resolution 3D model of the Homunculus Nebula. The shape model was developed using only a single emission line of near-infrared light emitted by molecular hydrogen gas. The characteristic 2.12-micron light shifts in wavelength slightly depending on the speed and direction of the expanding gas, allowing the team to probe even dust-obscured portions of the Homunculus that face away from Earth.

The Vela Nebula
We’re not certain, exactly, what the interior of a neutron star looks like, but mathematical models suggest they’re like this. Image Credit: By Robert Schulze – Own work, CC BY-SA 3.0, But it’s the ‘looking deeper into a neutron star’ that’s the problematic part. Nobody’s ever seen the inside of one.
Pulsars are thought to emit relatively narrow radio beams, shown as green in this animation. If these beams don't sweep toward Earth, astronomers cannot detect the radio signals. Pulsar gamma-ray emission (magenta) is thought to form a broader fan of radiation that can be detected even when the radio beam is unfavorably oriented. (No audio.) Credit: NASA/Fermi/Cruz deWilde
This Chandra image shows the Vela Pulsar as a bright white spot in the middle of the picture, surrounded by hot gas shown in yellow and orange. A jet of material is wiggling from the hot gas in the upper right. Image Credit: By NASA/CXC/PSU/G.Pavlov et al. – Public Domain,
