Trending Now - Astronomers Discover Rare Ancient Star in Early Universe

WHO:

Anirudh Chiti, team leader, Stanford University

Chris Davis, National Science Foundation Program Director for NOIRLab

Researchers involved in the MAGIC survey

WHAT:

Discovery of a rare, iron-deficient second-generation star designated PicII-503

PicII-503 has only 1/40,000th of the iron contained within the sun

PicII-503 has a carbon-to-iron ratio over 1,500 times greater than that of the sun

PicII-503 is the first confirmed example of a POP II star found in a faint dwarf galaxy

PicII-503 has the lowest concentration of iron ever seen beyond the Milky Way

The MAGIC survey lasted for 54 nights

WHERE:

Dwarf galaxy Pictor II, located around 150,000 light-years from Earth in the constellation Pictor

Observations conducted using the Dark Energy Camera (DECam) mounted atop the Víctor M. Blanco 4-meter Telescope

Very Large Telescope (VLT) in the Atacama Desert region of northern Chile

Baade Magellan Telescope

WHEN:

Discovery reported in 2026

Data collected during the MAGIC survey

WHY:

The discovery provides evidence of how the first generation of stars died to chemically enrich their successors

The rarity of such objects makes the discovery significant

HOW:

The team combined MAGIC data with observations from the VLT and Baade Magellan Telescope to analyze PicII-503

The Dark Energy Camera was used to identify the star among hundreds of others in the vicinity of Pictor II

In a groundbreaking discovery, researchers from Stanford University and the National Science Foundation have identified a rare, iron-deficient second-generation star known as PicII-503, located about 150,000 light-years away in the dwarf galaxy Pictor II. This star contains only one-fortieth-thousandth of the iron found in our sun and boasts a carbon-to-iron ratio that is over 1,500 times greater, making it the first confirmed example of a POP II star in a faint dwarf galaxy and the lowest concentration of iron ever observed beyond the Milky Way. The findings, reported in 2026, were made possible through a 54-night MAGIC survey, utilizing the Dark Energy Camera and observations from the Very Large Telescope and Baade Magellan Telescope to analyze this remarkable celestial object.
