Solar system is estimated to be about 4.57 billion years old: Research
Updated : 3 years, 1 month ago IST
Our solar system is estimated to be about 4.57 billion years old. Previous analyses of ancient meteorites have shown that minerals were created through chemical reactions with water as far back as 4.5 billion years ago. New findings from the Ryugu asteroid samples indicate that carbonates we

Research details wide diversity of galaxies in the early universe
Updated : 3 years, 2 months ago IST
New data from the James Webb Space Telescope (JWST) have revealed that the structures of galaxies in the early universe were much more diverse and mature than previously known. Scientists compared images of hundreds of galaxies taken by JWST for the Cosmic Evolution Early Release Science (CE

James Webb telescope reveals Milky Way-like galaxies in young universe
Updated : 3 years, 2 months ago IST
NASA's James Webb Space Telescope (JWST) reveal for the first time galaxies with stellar bars, elongated features of stars stretching from the centers of galaxies into their outer disks, at a time when the universe was a mere 25% of its present age. The finding of so-called barred galaxies,

Hubble finds ghost light among galaxies stretches far back in time
Updated : 3 years, 2 months ago IST
In giant clusters of hundreds or thousands of galaxies, innumerable stars wander like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any one galaxy in a cluster.

Study confirms light from outside our galaxy is brighter than expected
Updated : 3 years, 2 months ago IST
Washington [US], December 17 (ANI): Scientists analyzed new measurements showing that the light emitted by stars outside our galaxy is two to three times brighter than the light from known populations of galaxies, challenging assumptions about the number and environment of stars in the unive

Webb telescope 'Pearls' project brings exquisite views of distant galaxies
Updated : 3 years, 2 months ago IST
For decades, the Hubble Space Telescope and ground-based telescopes have provided us with spectacular images of galaxies. This all changed when the James Webb Space Telescope (JWST) launched in December 2021 and successfully completed commissioning during the first half of 2022. For astro

Scientists discover rare red spiral galaxy population from early universe
Updated : 3 years, 2 months ago IST
Spiral galaxies represent one of the most spectacular features in our universe. Among them, spiral galaxies in the distant universe contain significant information about their origin and evolution. However, we have had a limited understanding of these galaxies due to them being too distant t

Researchers reveal that meteorites could have given Earth building blocks
Updated : 3 years, 3 months ago IST
Even as detailed images of distant galaxies from the James Webb Space Telescope show us more of the greater universe, scientists still disagree about how life began here on Earth. One hypothesis is that meteorites delivered amino acids life's building blocks to our planet. Now, researchers h
