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
thanks for the correction. The corrected translation would be: SwRI scientists used data from the James Webb Space Telescope to model the geothermal processes in the subsurface that may explain how methane reached the surface of Eris and Maki Maki, two dwarf planets in the distant Kuiper Belt. The figure suggests three possibilities, including the likelihood that liquid water exists within these icy bodies at the edge of the solar system, far from the sun's heat.

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.

This image from Webb's MIRI (mid-infrared) camera shows the star system Beta Pictoris. A flat disk of dust fragments, formed by collisions between planetesimals (orange), dominates the landscape and is called the "main disk plane". In the lower left corner, Webb showed the true extent of the secondary disk (cyan (turquoise), which is inclined 5 degrees relative to the primary disk. Webb also discovered a previously unseen feature called the "cat's tail." A coronagraph (a black circle and two small disks) was used to block The light of the central star. Scale bar shows that the disks of Beta Peak (pictoris) span hundreds of astronomical units (AU), where one AU is the average distance from Earth to the Sun. (In our solar system, Neptune orbits the Sun at a distance of 30 AU) in this image , light at a wavelength of 15.5 microns is shown in cyan (turquoise) and 23 microns in orange (F1550C and F2300C filters, respectively).

The Webb Space Telescope discovered a 'cat's tail' made of dust in the Beta Pictoris system

  • No comments
Beta Pictoris is a solar system in the making and relatively close so that the gas disks can be seen. It turns out that Webb was able to discover a structure that was not noticed in photographs with less sensitive instruments, thus he discovered a disk of gas tilted from our main disk and because of our vantage point it looks like a cat's tail

An example of a supernova detected by the Dark Energy Survey within the field covered by one of the few detectors in the Dark Energy Camera. The supernova exploded in a spiral galaxy with redshift = 0.04528, which corresponds to a light travel time of about 0.6 billion years. For comparison, the quasar on the right has a redshift of 3.979 and a light travel time of 11.5 billion years. Credit DES Collaboration/NOIRLab/NSF/AURA/M.

Jupiter, the largest planet by far in our solar system, plays an important protective role. Its enormous gravitational field deflects comets and asteroids that might otherwise hit Earth, helping to create a stable environment for life to exist. But giant planets elsewhere in the universe don't necessarily protect life in their smaller, rocky neighbors.

The researchers developed an amplifier - a medium containing atoms that the photon coming from space passes through after the telescope key. The impact of the photon on the atom forces the atom to release a large number of photons identical to the original photon. The improvement in resolution will benefit any telescope, especially for medium-sized telescopes, and in particular for space telescopes
