Titanium has been discovered in the beautiful remnants of the Cassiopeia A supernova, about 11,000 light-years away. The element, used in electronics and jewelry, is thought to originate from the explosions of massive stars.
This discovery could help scientists understand what leads some giant stars to explode, according to the new study. Observations of the supernova were made using NASA's Chandra X-ray Observatory, which has been in operation since 1999, between 2000 and 2018. Scientists recently sifted through the data to understand more about the supernova that has captivated researchers for years.Senate Democrats have confirmed some of President Joe Biden’s picks for the federal bench this week in the face of President-elect Donald Trump’s calls for a total GOP blockade of judicial nominations – in part because several Republicans involved with the Trump transition process have been missing votes.
