Were the Very First Stars Really That Massive?
New research suggests the first stars weren't the behemoths we expected them to be — which might explain why we haven't seen them yet.

Could nearby relic galaxy NGC 1277 lead to the first stars?

Galaxy NGC 1277 hasn't formed stars in over 10 billion years.

The strongest-ever silicon signal that's inside of it could indicate the remains of the first stars of all.

Could nearby relic galaxy NGC 1277 lead to the first stars?
At 240 million light-years away, galaxy NGC 1277 hasn't formed new stars in over 10 billion years. Could it contain the first stars' ashes?

A close-up image of the Cosmic Infrared Background (CIB), showcasing light from the earliest stars and galaxies. The image, captured by the 2MASS telescope, reveals a surprisingly bright background, indicating prolific star formation in the early universe (redshift 1-7). The speckled appearance is due to the distribution of these ancient celestial objects. Black areas represent obscured regions.

Infrared image data from the Spitzer Space Telescope showing possible light from the first generation of stars, which formed hundreds of times more massive than our Sun, approximately 13 billion years ago. The gray areas represent foreground stars from our Milky Way Galaxy that have been digitally removed. The image reveals a diffuse glow, suggesting the existence of these massive, early stars in the universe.
