Researchers focus AI on Finding Exoplanets

New research from the University of Georgia reveals that artificial intelligence can be used to find planets outside of our solar system. The recent study demonstrated that machine learning can be used to find exoplanets, information that could reshape how scientists detect and identify new planets very far from Earth.

“One of the novel things about this is analyzing environments where planets are still forming,” said Jason Terry, doctoral student in the UGA Franklin College of Arts and Sciences department of physics and astronomy and lead author on the study...

Star Formation in Distant Galaxies by the James Webb Space Telescope

Galaxies at a great distance
The James Webb Space Telescope captured this image of a galaxy cluster (SMACS0723). The five zoomed in galaxies are so far away that we observe them as they were when the Universe was between one and five billion years old. Today the Universe is 13.7 billion years old. Credit: Image adapted from image release by NASA, ESA, CSA, STScI.

Thanks to the James Webb Space Telescope’s first images of galaxy clusters, researchers have, for the very first time, been able to examine very compact structures of star clusters inside galaxies, so-called clumps. In a paper published in the Monthly Notices of the Royal Astronomical Society, researchers from Stockholm University have studied the first phase of star formation in distant galaxies.

“The galaxy clusters we examined are so massive that th...

New Webb Image Reveals Dusty Disk Like Never Seen Before

These two images are of the dusty debris disk around AU Mic, a red dwarf star located 32 light-years away in the southern constellation Microscopium. Scientists used Webb’s Near-Infrared Camera (NIRCam) to study AU Mic. NIRCam’s coronagraph, which blocked the intense light of the central star, allowed the team to study the region very close to the star. The location of the star, which is masked out, is marked by a white, graphical representation at the center of each image. The region blocked by the coronagraph is shown by a dashed circle.

Discovering Rare Red Spiral Galaxy Population from Early Universe with the James Webb Space Telescope

Morphology of galaxies contain important information about the process of galaxy formation and evolution. With its state-of-the-art resolution, NASA’s James Webb Space Telescope has now captured several red spiral galaxies in its first image at an unprecedented resolution. Researchers have now analyzed these galaxies, revealing that these are among the furthest known spiral galaxies till date. The analysis further detected a passive red spiral galaxy in the early universe, a surprising discovery.

Spiral galaxies represent one of the most spectacular features in our universe. Among them, spiral galaxies in the distant universe contain significant information about their origin and evolution...
