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 […]

Saturn’s moon Mimas may have a subocean

97 Comments / Planetary science/ Astrobiology, Solar system, Uncategorized /

Astronomers discover enormous evidence that a geologically young ocean exists beneath the icy crust of Saturn’s moon Mimas. A French-led research team observed changes in Mimas’s orbit and rotation and reported that a hidden ocean 12 to 18 miles ( 20 to 30 kilometers) beneath the icy crust was more likely a prolonged rocky core.

NASA’s Webb’s Holiday images of Uranus, its rings, and moons

103 Comments / James Webb Space Telescope, NASA, Solar system /

NASA’s Webb captured a marvelous image of Uranus showing its inner and outer dim rings(including the extremely diffuse dim ring the Zeta Ring) and many of its moons during December 2023. This image is a two-colored version that shows atmospheric details of the planets such as a seasonal north polar cap and storms. This new

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

Hubble’s Spectacular view of NGC 2210 in the Large Magellanic Cloud

121 Comments / Hubble Space Telescope, NASA, Star Clusters, Stars /

This image shows a tightly packed globular cluster called NGC 2210, which is located about 160,000 light-years away within the Large Magellanic Cloud (LMC). The Large Magellanic Cloud and Milky Way are gravitationally attached. Globular Clusters are a stable, tightly attached group of stars that contain thousands to millions of old stars. Globular clusters are

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

1,599 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

James Webb find new surprises IN a galaxy’s organic biosignatures near Black Holes

239 Comments / Black holes, James Webb Space Telescope, NASA /

Research by Oxford University is the first of its kind to study tiny dust molecules in the central active regions of active galaxies by the use of early observations captured by NASA’s Webb. The research is the first U.K.-led paper to use spectroscopic data from JWST’s MIRI (Mid-Infrared Instrument) and addresses one of the biggest

Citizen Scientists SHARPEN new spectacular images of Europa from NASA’s Juno

103 Comments / NASA, Solar system /

Citizen scientists have shared unique insights into the close flyby of Europa by NASA’s Juno Spacecraft. Thanks to processing raw images captured by JunoCam, the spacecraft’s public-engagement camera, members of the general public have created deep-space portraits of Europa that are indeed worthy of further scientific examination. According to Juno principal investigator Scott Bolton, Juno

NASA’s Webb’s Mid-Infrared Instrument is prepared to perform science

114 Comments / James Webb Space Telescope, NASA /

The James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) has concluded its post-launch preparations and is now prepared to do science. The last MIRI mode to be approved was its coronographic imaging capability, which uses two different designs of masks to block off light from a star to make observations of the star’s orbiting planets. These
