Hace 5 días · One such galaxy, JADES-GS-z14-0 (shown in the pullout), was determined to be at a redshift of 14.32 (+0.08/-0.20), making it the current record-holder for the most distant known galaxy. This corresponds to a time less than 300 million years after the big bang. Get the JADES image details and downloads.
Hace 5 días · Located 12.5 million light-years away in the constellation of Canes Venatici, the Hunting Dogs, NGC 4449 has much in common with our very own Large Magellanic Cloud (LMC), the satellite...
Hace 4 días · Distance estimates put WR 134 about 6,000 light-years away, making the frame over 100 light-years across. Shedding their outer envelopes in powerful stellar winds, massive Wolf-Rayet stars have burned through their nuclear fuel at a prodigious rate and end this final phase of massive star evolution in a spectacular supernova explosion.
Hace 5 días · 4 min read. The James Webb Space Telescope has discovered what appears to be a new record-holder for the most distant known galaxy, a remarkably bright star system that existed just 290 million years after the Big Bang, NASA said Thursday.
