Heavy elements are needed to make living things. The lens galaxy was missed in previous studies because the more distant, host galaxy harbors a younger stellar population, causing it to shine brightly. Traces of radioactive iron-60, a strong indicator of supernova debris, is buried in the sea floor right across the globe. Furthermore, the expelled envelope interacts with the expanding front, making the supernova appear uniform, but much brighter than expected. This is the cause of all types of supernova except type Ia. This is a relatively common way for small stars to die, but in this case, the resulting detonation crashed into a massive shell of gas surrounding the dwarf, lighting it up so that we could see it from 238 million light-years away.

So the astronomers advocated a second explanation, which "required only well demonstrated physics: gravitational lensing,” says coauthor Marcus Werner (University of Tokyo and Duke University, U.S.).

"SN 2006gy is only one arcsecond from an active galactic nucleus in the host galaxy, and it is seen amid bright galaxy light that is almost impossible to subtract from the ground," Smith explains.

Sometimes they are brighter than the whole rest of the galaxy. While several other superluminous supernovae could also fit by the scenario described by Jerkstrand’s team, it will be difficult to tell — they are all farther away and if iron has left fingerprints in their spectra, the imprints can’t be seen. But whether PS1-10afx was an unnaturally bright supernova that defies explanation or a typical supernova brightened due to a chance cosmic alignment — where intervening matter worked like a lens to deflect and intensify the background light — was highly debated.

The short answer is yes. [3] This drives a shock wave into the surrounding interstellar medium. By: Shannon Hall But, the collapse of the core is so rapid (about 23% of the speed of light) that a huge shock wave is produced. They came so close, in fact, that they shared a common envelope, basically trading gas between them. Sky & Telescope is part of AAS Sky Publishing, LLC, a wholly owned subsidiary of the American Astronomical Society. The problem is this: PS1-10afx doesn’t easily match these two additional characteristics. The ball, in other words, is in the theorists’ court.

July 23, 2003, By: Kelly Beatty June 30, 2016, By: Joshua Roth In a star like the Sun, nuclear fusion turns hydrogen into helium. The core-collapse of a massive star doesn’t usually leave much iron behind. Rather, Quimby’s team has argued since the supernova’s discovery that PS1-10afx matched a typical type Ia supernova in every measurable characteristic, except brightness. Woosley also notes that it’s difficult to precisely estimate the amount of iron present based on spectra taken so long after the supernova went off. As the stars continued to spiral inward, the common envelope was ejected so­me 10 to 200 years before the stellar cores merged and exploded. This sweeps up an expanding shell of gas and dust, which we see as a supernova remnant. It could be dangerous if a supernova explosion happened very close to the Earth.

[11] SN 1987A was also bright enough to see without a telescope. This scenario explains most of the observations of the event, including its extreme brightness and the way that brightness changed over time. “I am skeptical,” says Stan Woosley (University of California, Santa Cruz).

supernova explained

There are a few places in the universe that defy comprehension. “This makes the lens galaxy hard to see over the brighter glare from the supernova host,” says Quimby. In addition, the discovery of the lensing foreground galaxy also allows the team to conclude that PS1-10afx is indeed a Type Ia supernova, the death cry of a white dwarf. People in the southern hemisphere saw it. Supernovas are usually sorted into Type I and Type II supernovas. The core collapses, and explodes.

“If there was a massive galaxy in front of PS1-10afx, it could warp space-time to form magnified images of the supernova.". We're talking about a …
