Indian Astronomers Unravel Mysteries of Planet Formation in Unique Tri-Star System

Breaking News, Idea & Innovations, Space

December 11, 2024 – In a groundbreaking achievement, Indian astronomers from the National Institute of Science Education and Research (NISER), Odisha, have unveiled new insights into planetary formation within the unique tri-star system, GG Tau A, located 489 light-years from Earth. Using the advanced Atacama Pathfinder Experiment (APEX) radio telescope in Chile's Atacama Desert, the team, led by scientist Liton Majumdar, has detected molecular emissions within the protoplanetary disk a giant rotating disk of gas and dust. These emissions, originating from the coldest and densest regions of the system, serve as fundamental building blocks for planet formation. GG Tau A, an infant solar system approximately 5 million years old, features three stars orbiting one another, surrounded by ...

Solar Orbiter Captures Most Detailed Images of the Sun Yet

Breaking News, Learning & Developments, Space

From a staggering distance of 74 million kilometers, the ESA/NASA Solar Orbiter has delivered breathtaking new images of the Sun, showcasing unprecedented details of our closest star. Despite the vast distance, the Orbiter's advanced instruments have captured some of the highest-resolution images ever taken, shedding light on the Sun's magnetic and plasma dynamics. Launched in 2020, the Solar Orbiter is on a mission to unravel the Sun's mysteries, from its solar wind to the complex behavior of its magnetic field and dynamic eruptions like solar flares. Among its objectives is producing detailed, high-resolution imagery of the Sun's surface, a feat it accomplishes using cutting-edge instruments: Polarimetric and Helioseismic Imager (PHI): A German contribution capturing the Sun's ma...

Researchers Propose New Definition for Planets Potentially Reclassifying Celestial Bodies Across the Universe

Breaking News, Idea & Innovations

A recent study published in The Planetary Science Journal proposes a new definition of a "planet" that could challenge the longstanding criteria established by the International Astronomical Union (IAU). The team of researchers from the United States and Canada, led by Dr. Jean-Luc Margot from the University of California, Los Angeles, aims to address the issues with the current IAU Resolution B5, which was established in 2006 and led to the demotion of Pluto from a planet to a dwarf planet. The current IAU definition requires a celestial body to orbit the Sun, be nearly round in shape, and have cleared its orbit of other debris. This definition, however, excludes exoplanets and is considered vague by many in the scientific community. Dr. Margot and his team argue that a more quantitati...
