The Korea Astronomy and Space Science Institute (KASI) and the National Aeronautics and Space Administration (NASA) have jointly developed the SPHEREx space telescope, which has now shared its global data with researchers. The archive site contains a wealth of information gathered during full-scale observations that began on March 12.
SPHEREx aims to investigate key scientific questions such as the origin of the universe, galaxy formation, and cosmic ice distribution. The telescope captured over 600 images in just one day, generating about 3,600 images, which will be combined into a 3D all-sky map every six months.
In total, 6,000 observation data cuts are being prioritized for release globally, allowing researchers to conduct various scientific studies. Initially, the released data consists of images obtained over a one-and-a-half-week period starting from May 1.
Future releases will occur within 60 days after initial collection, with the telescope’s raw data processed to remove errors and distortions. The processed observation data, along with processing procedures, will be made available for independent research.
KASI researchers have also selected and synthesized a new image of the Tarantula Nebula, which is being released as part of this effort. According to Yang Yu-jin, a senior researcher at KASI, “We are conducting further data processing work to enhance scientific research using observation data from over 120 research topics solicited from the Korean astronomical community.”
