Star Explosions

A discovery by NASA via the Chandra X-ray Observatory might turn out to be a key step in examining precisely how some massive stars explode. The space company mentions that its scientists have discovered bits of titanium exploding out of a renowned supernova. Which is an exceptionally bright super explosion of a star. For years, scientists face challenges in understanding how giant stars — with masses 10 times that of the Sun — blast. This incident took place when they ran out of fuel. The conclusions are on the basis of interpretations of the remains of a supernova called Cassiopeia A (Cas A).

Details on Cassiopeia A (Cas A) are as follows:

  • Cas A is one of the youngest supernova fragments
  • The age of Cas A is 350 years
  • It is in our galaxy about 11,000 light-years from Earth

A post by NASA on its social media account (Instagram) with a picture of star explosions, captions it “We’re blown away”. In addition, it also adds the amount of stable titanium generated in Cas A surpasses the total mass of the Earth.

It further adds, “Latest 3D computer simulations indicate that these are neutrinos or extremely low-mass subatomic fragments. These are made in the formation of the neutron star that plays a vital role in powering bubbles that pace away from the neutron star. These bubbles continue to drive the shock wave ahead in order to trigger the supernova explosion.”

The study is conducted by Toshiki Sato of Rikkyo University in Japan. He says that that scientists believe for the most part of the titanium that is consumed in our daily lives.

Applications of Titanium which is an outcome of a huge star explosion include the following:

  • Electronics
  • Jewelry

Toshiki says that as of now they have a capture of the moment right after stable titanium forms. Astrophysicists take more than 18 days of Chandra’s observation time from the moment the supernova Cas A takes between 2000 – 2018.
Keiichi Maeda is the co-author, and he is from Kyoto University in Japan. He says, “We have not once seen this sign of titanium bubbles in a supernova trace before. An outcome which is only possible with Chandra’s exceedingly clever images.” The outcome is a crucial step in the direction of answering the mystery of how these stars blast as supernovae, he adds.

A few days back, NASA celebrates the 31st anniversary of the initiation of the Hubble Space Telescope by intending the observatory at one of the sharpest stars seen in our galaxy. It shares an image of AG Carinae, which locates roughly 20,000 light-years away.

The Hubble Space Telescope launches 31 years ago on 24th April and still captures spectacular interstellar images. Stars like the AG Carinae are amongst the largest and brightest. It starts developing around 10,000 years ago and is prone to survive only a few years.
