Recent questions
What is the farthest star discovered in 2022?
In 2022, astronomers discovered the farthest single star named Irondale, located 12.9 billion light years away with a present proper distance of 28 billion light years. This star is 8.2 billion years older than the Sun and Earth, making it a significant find in the field of astronomy.
What telescope first spotted the star Irondale?
Irondale was first spotted by the Hubble Space Telescope in the Sunrise Arc. The telescope observed the star showing constant brightness for over three and a half years, indicating it as a gravitationally lensed bright star, leading to its discovery.
What is the potential significance of Irondale's discovery?
The discovery of Irondale is significant as it could be a population 3 star, rare and dim stars believed to have formed in the early universe with low metallicity. This finding could provide valuable insights into the early stages of star formation and the evolution of the universe.
What did the James Webb Space Telescope reveal about Irondale?
The James Webb Space Telescope revealed Irondale as a b type star with a surface temperature of 13,000 to 16,000 degrees Celsius and a luminosity between 600,000 to 1 million times that of the Sun. This information challenges existing astrophysical models and expands our understanding of stellar evolution.
What did the New Horizons probe discover about Pluto?
The New Horizons probe, launched in 2006, reached Pluto after nine years and revealed a geologically active surface with bumpy volcanoes and no impact craters. This discovery hints at recent volcanic activity on Pluto, possibly fueled by leftover heat from its formation, shedding light on the dwarf planet's geological history.
