A new study has revealed more spiral galaxies in the universe’s youth than astronomers had expected. The universe is about 13.8 billion years old and is home to different kinds of galaxies, from spiral to elliptical and those with or without bulges. Astronomers previously believed spiral galaxies formed about 6 billion years ago, but a…

This handout image obtained on May 30, 2024 courtesy of NASA/ESA/CSA STScI shows an infrared image from NASA’s James Webb Space Telescope. A 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 earliest known galaxy. | Photo Credit: AFP NASA’s James…

A big open problem in cosmology is the Hubble tension. There are two equally valid ways to measure how fast the universe is expanding, but they have yielded two very different estimates. No amount of rechecking and refining calculations has made this tension go away. In a study published recently in Monthly Notices of The…
