题目:A New Visualization of the Pillars of Creation

摘要:the Pillars of Creation in the heart of the Eagle Nebula have captured imaginations worldwide with their arresting, ethereal beauty. NASA has released a new 3D visualization of these towering celestial structures using data from NASA's Hubble and James Webb space telescopes. This is the most comprehensive and detailed multiwavelength movie yet of these star-birthing clouds.

题目:Some Challenges for the Compton Telescope

摘要:In the MeV band, the sensitivity to gamma ray sources is much worse than in other bands. Therefore, our detection of this energy band is insufficient. The main interaction that occurs with gamma rays in this energy band is Compton scattering. Due to the peculiarities of Compton scattering, a single photon case can only limit the point source direction to a single cone. In order to better reconstruct the location of the point source, it is necessary to reconstruct the tracks of the Compton events and reconstruct the image of multiple conic overlapping images, which is the challenges of the Compton telescope.
