A mosaic taken by the European Space Telescope over a period of about 26 hours is the largest and most detailed visible-light image of the center of the galaxy. The image is not intended to immediately discover new planets, but to provide a reference point
Simulation of an expanding mini-universe inside a gravity star forming a Gravastar

Theoretical model: A tiny universe may form inside a collapsing star

  • One response
Physicists have developed a dynamical solution to Einstein's equations in which an expanding region forms inside a collapsing star and stops the collapse. The result is a gravistar - a theoretical alternative to a black hole that has no singularity or event horizon

Webb captures the “final breath” of a sun-like star in the Helix Nebula

  • No comments
The sharpest infrared observation yet of a nearby planetary nebula reveals comet-like bonds of gas and dust, illustrating how material from a dying star becomes the seeds of future systems.
This composite image shows a portion of the interstellar medium where scientists searched for sulfur using X-ray imaging of Charisma. The X-ray binary system GX 340+0 is the blue dot in the center. The image is a blend of X-ray (shown in dark blue), E-ray, and light images. Credit: DSS/DECaPS/eRosita/NASA's Goddard Space Flight Center

X-ray satellite CHRISMA reveals missing sulfur in Milky Way
