By definition, each population group shows the trend where lower metal content indicates higher age of stars. Hence, the first stars in the universe (very low metal content) were deemed population III, old stars (low metallicity) as population II, and recent stars (high metallicity) as population I. [6] The Sun is considered population I, a ...
HE 1327-2326, discovered in 2005 by Anna Frebel and collaborators, [2] was the star with the lowest known iron abundance until SMSS J031300.36−670839.3 was discovered. [5] The star is a member of Population II stars , with a solar-standardised iron to hydrogen index [Fe/H], or metallicity , of −5.4±0.2.
Mathilde Jauzac said observing the stars would shine a light on how stars were born during the cosmic noon [Mathilde Jauzac] Dragon Arc is located behind a cluster of galaxies called Abell 370.
HD 140283 (also known as the Methuselah star) is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy.

An environmentally beneficial species native to Kentucky was one of 21 species recently delisted. US declares species once found in Kentucky extinct. What does it mean for water quality?
It had been thought that NGC 2808, like typical globular clusters, contains only one generation of stars formed simultaneously from the same material. In 2007, a team of astronomers led by Giampaolo Piotto of the University of Padua in Italy investigated Hubble Space Telescope images of NGC 2808 taken in 2005 and 2006 with Hubble's Advanced Camera for Surveys.
