Beyond what was thought Possible: New data from Webb unearths a mysterious early galaxy

283 Comments / Astronomy & Astrophysics, Galaxies, James Webb Space Telescope, NASA /

Our understanding of how galaxies form and the nature of dark matter could be upside down thanks to observations of a stellar population bigger than the Milky Way from more than 11 billion- years ago that should not exist. A study published today in Nature using new data from the James Webb Space Telescope discovers […]

Hubble sees double clusters of Bright Galaxies

1 Comment / Galaxies, Galaxy Clusters, Hubble Space Telescope, NASA, Uncategorized /

This Hubble image shows a massive cluster of shiny bright galaxies identified as galaxy cluster Abell 3192. This galaxy Cluster is filled with hot gas that produces powerful X-rays, and it’s covered in a halo of dark matter. All of the unseen material thus the amount of galaxies seen in this image makes the galaxy

New Dark Matter theory explains two aspects of Astrophysics

104 Comments / Astronomy & Astrophysics, Galaxies /

It is widely believed that dark matter constitutes approximately 85% of the universe. Dark matter is matter that does not interact with light and is poorly understood, making it extremely difficult to detect. A research team, led by Professor Bai-Bo Yu from the University of California, has proposed that Self-Interacting Dark Matter (SIDM) theory can

James Webb Space Telescope found Hydrogen-Alpha Emission in the era of reionization

1,565 Comments / Galaxies, James Webb Space Telescope, Stars /

A team of astronomers with the leader named Pierluigi Rinaldi discovers Hydrogen- Alpha Emissions during the era of Reionization. The detection of H-alpha emissions was possible thanks to the farthest images taken by the Mid-Infrared (MIRI) Instrument on the James Webb Space Telescope. The study has been accepted in the Astrophysical Journal and is currently

The Hubble Space Telescope captures this inspiring image of a massive galaxy cluster named Abell 1351 with its Wide Field Camera 3 and Advanced Camera for Survey. Abell 1531 is located more than 4 billion light-years away and lies within the northern constellation, Ursa Major. The image is filled with light streaks that are actual

James Webb Space Telescope will help uncover more of the early universe

131 Comments / Galaxies, James Webb Space Telescope, NASA /

Before the James Webb Space Telescope, space telescopes have looked back at lights from galaxies that reached a period of no earlier than 400 million years after the big bang. One question that remains unsolved and important even today is what were the first galaxies like when the universe was experiencing a time phase known

Astronomers learn and discovers how galaxies form through galactic mergers

1 Comment / cosmic collisions, Galaxies /

In the United Kingdom (UK), astronomers announce that they find how galaxies such as the Milky Way formed over more than 10 billion years through multiple varieties of galaxies colliding together. Galaxies are the largest single islands in the universe in which their origin of how they form or evolve is a very old question
