Research Presently Discovered a rare Dwarf Galaxy that's Loaded with Precious Elements

Scientists have been searching for the source of some of the most precious metals on Earth - including gold, silver, &  platinum - for almost six decades. And now we strength finally have the answer.
Heavy, and often precious elements like these are called r-process rudiments, and they need an incredible amount of energy to create. So far, no one’s been able to give details how they came to exist in the Universe.
But the discovery that an very old dwarf galaxy called Reticulum II - about 98,000 light-years from Earth - has stars that hold a "whopping" amount of these metals could lastly bring an end to this secrecy.
"sympathetic how heavy, r-process elements are formed is one of hardest evils in nuclear physics," said one of the group, physicist Anna Frebel from MIT.
"The production of these actually heavy elements takes so much energy that it's near impossible to make them experimentally. The process for creation them just doesn't work on Earth. So we have had to use the stars and the matter in the cosmos as our lab."
Discovered presently previous year, the tiny Reticulum II galaxy is orbiting our own Milky Way, and is one of the closest dwarf galaxies ever establish. It’s considered one of the top candidates for detecting the famously indefinable dark matter, and now it also looks like the top place for us to figure out how some of our favourite elements originate in the Universe.
By analysing the starlight from more than a few of the brightest stars in the Reticulum II galaxy with the Magellan telescopes at the Las Campanas Observatory in Chile, Frebel and her team strong-minded that they restricted massive amounts of r-process elements. But here’s the obsession - there’s no way they could have shaped them on their own.
"When we interpret off the r-process content of that opening star in our telescope, it presently looked wrong, like it could not have approach out of this galaxy!" said one of the team, graduate learner Alexander Ji. "I spent a long time creation sure the telescope was sharp at the right star."
"Amazing to think about is that all the gold at first here on Earth sank into the planet's centre since the early Earth was melt," said Ramirez-Ruiz. "So all the gold bars we have today on or near the surface is from asteroid impact."
"As we've been saying, the gold wasn't complete in the asteroids, it was probably complete in a neutron star amalgamation," Frebel adds. "It then mixed into the cloud of gas and powder in which all the asteroids and planets formed. That gold was then elated to us on Earth as a special release."
What’s crazy is that these star mergers were in fact extremely rare in the early on Universe, which means much of the gold atoms, for example, probable come from the same collisions.
"Because presently one of these neutron star mergers shaped so much gold, probably all of the gold atoms that are in the four of us in this roundtable discussion came from the same event," said Ramirez-Ruiz. "So we're not only connected by genetics, but by these exotic phenomena that happen in the space."

So not only are we all complete of stars, we all contain precious metals born from the same cosmic collisions that happen billions of years ago, the results of which somehow made it into our own cells today. Go hug your adjacent pet, because that is freaking-awesome.
