The James Webb Space Telescope reveals the unseen forces that shape planetary systems

  • No comments
Researchers studying the Orion Nebula with the James Webb Space Telescope found that ultraviolet radiation from massive stars prevents the formation of giant planets in young systems by scattering their building materials.

Cosmic Time Runs Back: Webb Space Telescope Discovers 'Dead' Galaxy 13 Billion Years Old

  • No comments
This galaxy experienced a tumultuous and fast life: the star formation process worked quickly and suddenly ended, a situation that is not expected at such an early stage in the evolution of the universe. It is still unclear whether the "frozen" state of the galaxy is temporary or permanent, and what is the reason for the cessation of the star formation process
The galaxy AM 1054-325 has been warped from a normal pancake-like spiral shape into an S shape by the gravitational pull of a neighboring galaxy, as seen in this Hubble Space Telescope image. As a result, new star clusters were formed along a tidal tail stretched over thousands of light years, resembling a string of pearls.

The galaxy is currently 25 billion light-years away, but when light began to travel from it to us about 12.5 billion years ago, it was much closer, because the universe is expanding

"Dead" galaxies mysteriously ran out of fuel to form stars in the early universe

When the universe was about three billion years old, only 20% of its current age, it went through the most abundant period of star birth in its history. But when Hubble and ALMA looked at cosmic objects during this period, they found something strange: six ancient massive "dead" galaxies that had run out of the cold hydrogen gas needed to form stars
The three images from top to bottom show what the evolutionary trajectory of galaxies such as XMM-2599 looks like, which starts out as a dusty galaxy full of star formation, then becomes a dead galaxy, possibly becoming the "brightest galaxy cluster" Credit: (NRAO/AUI/NSF/ B.

This image shows the galaxy cluster MACS J1149.5 + 2223 taken by the NASA / ESA Hubble Space Telescope. The image in the magnifying square is the distant galaxy MACS1149-JD1, as seen 13.3 billion years ago and recently observed by Alma. The oxygen concentration discovered by 'Alma' is depicted in red.

"This diagram explains how the light from the distant galaxy is disrupted by the gravitational influence of a nearby galaxy that is in the way, acting like a lens and making the distant object appear blurry but bright. This process creates rings of light known as Einstein rings. Analysis of the disruption has revealed some of the star-producing galaxies At a great rate and brightness in the light of 40 trillion suns and it has been magnified by gravitational lensing up to 22 times. Figure: Alma (ESO/NRAO/NAOJ), L. Calçada (ESO), Y. Hezaveh et al.

An infrared image of the Cygnus X star-forming region colored with wavelength-coded artificial colors. Light at 3.6 microns is colored blue, light at 4.5 microns in blue-green, 8 microns in green and 24 microns in red. These images were taken before the Spitzer mission ran out of cooling gas in 2009, becoming a "hot" mission.
