Webb Telescope Uncovers Mysterious Smooth Disk Around Star Vega

The James Webb Space Telescope has captured images of a remarkably smooth, pancake-like circumstellar disk around the star Vega, suggesting no exoplanets have formed there. This finding challenges current understanding of planet formation, as similar stars like Fomalhaut show gaps in their disks indicative of exoplanets. Researchers are puzzled by the differences between these systems and are considering the implications for the prevalence of exoplanets in the galaxy.

Webb Telescope Uncovers Mysterious Smooth Disk Around Star Vega

The James Webb Space Telescope has provided new insights into the debris disk surrounding the star Vega, revealing a smooth structure without clear planetary influence, challenging previous ideas about planetary formation. The disk's appearance, reminiscent of the depiction in Carl Sagan's 'Contact,' lacks the typical ring formations seen in other systems, prompting researchers to reconsider the diversity of exoplanet systems. The findings, which suggest possible unseen influences within the disk, are detailed in upcoming papers in The Astrophysical Journal.

Extragalactic Discovery: Newborn Star's Spinning Disk Found in Another Galaxy

Astronomers have observed a circumstellar disk around a newborn star in the Large Magellanic Cloud, a neighboring galaxy of the Milky Way. This is the first time such a disk has been seen outside of our galaxy. The star is larger and more luminous than the sun, and the disk has a diameter about 10 times larger than the one that encircled the sun when it formed. The detection was made using the ALMA telescope in Chile. The discovery provides valuable insights into star formation in different galactic environments.

Unveiling the Secrets of CI Tauri's Inner Ring

Using ESO's Very Large Telescope, astronomers have studied the inner dusty ring of the young star CI Tauri, located in the Taurus molecular cloud. The observations identified a highly inclined resolved inner disk, whose inner edge is located at a distance of about 21 times the radius of CI Tau from the star. The inner disk of CI Tau showcases a strong misalignment relative to the outer disk seen at submillimeter wavelengths, which could be induced by magnetic warping or by gravitational torques induced by a close-in massive companion. The results also shed more light on the magnetospheric accretion region of CI Tau.
