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...

Trio of Infant Planets discovered around Newborn Star

Last year, the Dawn spacecraft spied organic material near Ernutet crater on the dwarf planet Ceres, largest denizen of the asteroid belt. A new analysis suggests those organics could be more plentiful than originally thought. Credit: NASA / Hannah Kaplan

New technique could find some of the youngest planets in our galaxy. Two independent teams of astronomers have uncovered convincing evidence that three young planets are in orbit around an infant star known as HD 163296. Using a new planet-finding strategy, the astronomers identified 3 discrete disturbances in a young star’s gas-filled disk: the strongest evidence yet that newly formed planets are in orbit there.

Over the past several years, ALMA has transformed our understanding of protoplanetary disks – the gas- and dust-filled planet f...

Rings around Young Star suggest Planet Formation in progress

An ALMA image of the star HD 163296 and its protoplanetary disk as seen in dust. New observations suggested that two planets, each about the size of Saturn, are in orbit around the star. These planets, which are not yet fully formed, revealed themselves in the dual imprint they left in both the dust and the gas portions of the star’s protoplanetary disk.

Rice University astronomers and colleagues have for the first time mapped gases in 3 dark rings around a distant star. The rings mark spaces where planets are thought to have formed from dust and gas around the star...
