Researchers at Johns Hopkins have developed a new mathematical algorithm called ImageMM that significantly improves the clarity of images captured by ground-based telescopes by effectively correcting atmospheric distortions, potentially rivaling space telescopes in image quality while maintaining the ability to survey large areas of the sky.
The Hubble Space Telescope captured a detailed image of a star cluster in the Large Magellanic Cloud, a nearby satellite galaxy of the Milky Way, providing insights into star formation and galactic evolution in different environments.
Ground-based astronomers are overcoming Earth's atmosphere by using large, powerful telescopes placed in optimal locations and employing adaptive optics. Adaptive optics systems compensate for atmospheric distortion by creating artificial guide stars and using deformable mirrors to un-distort incoming light. This technology has allowed ground-based telescopes to outperform space-based telescopes in imaging quality, making ground-based astronomy a cost-effective and superior option for high-quality astronomical imaging.
NASA's James Webb Space Telescope has captured an image of a protostar named HH12, located 1,300 light years from Earth, providing new insights into the formation of stars. The image reveals pinkish-red jets shooting in opposite directions, indicating the expulsion of angular momentum through magnetic fields. This is the first time scientists have obtained a "good color image" of a protostar, which will also shed light on the birth of our own Sun. The James Webb Space Telescope, launched two years ago, is situated over one million miles away and has been delivering stunning images of deep space.
