Astronomers Discover Twin Stars Orbiting Galactic Black Hole: A World-First Revelation

Breaking News, Learning & Developments, Space

In an unprecedented discovery, astronomers led by Florian Peißker from the University of Cologne, Germany, have identified a binary star system named D9 orbiting the supermassive black hole Sagittarius A* at the center of the Milky Way. This groundbreaking find, published in Nature Communications, unravels mysteries surrounding hypervelocity stars and the extreme environment near black holes. Binary star systems, where two stars orbit each other, are common in the universe, but none have been observed near a supermassive black hole until now. Using the Very Large Telescope, the team detected D9 through subtle shifts in its starlight, known as the Doppler effect, confirming its binary nature. The D9 system, approximately 2.7 million years old, likely formed elsewhere in the galaxy bef...

Big Bang to Boundless Expansion: A Physicist’s Guide to the Ever-Growing Universe

Breaking News, Space

Have you ever tried to imagine how the Universe expands? Picture baking a muffin. As it bakes, the batter rises, and chocolate chips spread apart. The Universe’s expansion works similarly except there's no pan or edge. It grows into itself, an idea that’s as fascinating as it is hard to grasp. Unlike a muffin expanding into a baking pan, the Universe doesn’t expand into anything. It’s all dough no pan. Even if a pan existed, it would also be part of the Universe and would expand with it. This concept is mind-boggling because it’s so different from anything we experience in daily life. It’s like asking what’s farther north than the North Pole. Yet scientists define the Universe’s expansion by observing galaxies moving away from us, not by needing something for the Universe to expand i...

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 ...

ISRO Successfully Launches PROBA-3 Satellite for European Space Agency

Breaking News, Space, Tech

In a significant achievement, the Indian Space Research Organisation (ISRO) successfully launched the European Space Agency’s (ESA) PROBA-3 satellite aboard its trusted Polar Satellite Launch Vehicle (PSLV-C59) on its 61st commercial mission. The launch signifies another milestone in India’s growing prominence in the global space sector and highlights international collaboration in cutting-edge space exploration. PROBA-3, short for Project for Onboard Anatomy, is a groundbreaking solar mission by the ESA. The mission is specifically designed to study the Sun's corona, the outermost layer of the Sun's atmosphere, with unprecedented precision. The mission consists of two spacecraft, each designed to perform a unique and interdependent role. The Coronagraph Spacecraft (CSC), weighing 31...

Could a Rogue Planet Join Our Solar System? Scientists Explore the Possibility

Breaking News, Space

In 2017, the first confirmed interstellar visitor, Oumuamua, zipped through our Solar System, followed by Comet 2I/Borisov in 2019. These fleeting guests sparked curiosity about interstellar objects (ISOs) and rogue planets uncharted wanderers that could traverse space and potentially interact with our Sun. New research explores the tantalizing idea that the Solar System could permanently capture one of these cosmic drifters, and what such an event might mean. The study, published in Celestial Mechanics and Dynamical Astronomy by Edward Belbruno and James Green, delves into the dynamics of phase space an intricate mathematical framework used to describe the possible states of a system like our Solar System. Phase space reveals pathways where an interstellar object could become gravitati...

Gravitational Wave Hot Spot Detected in Southern Hemisphere, Raising Questions About Cosmic Activity

Breaking News, Idea & Innovations, Learning & Developments, Space

Astronomers using the MeerKAT Pulsar Timing Array in South Africa have unveiled groundbreaking insights into the universe’s gravitational wave background, including the discovery of a curious "hot spot" in the Southern Hemisphere. The findings, published in the Monthly Notices of the Royal Astronomical Society, suggest a more active universe than previously believed, potentially altering our understanding of supermassive black holes and their role in cosmic evolution. The Gravitational Wave Background Gravitational waves, ripples in the fabric of space-time, are created by massive objects like black holes and neutron stars as they orbit or collide. These waves, first detected in 2015, exist across a spectrum, with the slowest and most powerful waves stemming from supermassive black h...

Venus Never Had Oceans Study Confirms Ending Decades of Speculation

Breaking News, Learning & Developments, Space

Venus often referred to as Earth’s twin due to its similar size and rocky composition has been at the center of one of astronomy’s most enduring mysteries: Did it ever host oceans? A new study has finally provided an answer, and it’s not what some scientists had hoped. According to research published in the journal Nature Astronomy, Venus has likely been a dry, desolate world throughout its history. By analyzing the chemical composition of Venus’s atmosphere, scientists concluded that the planet’s interior has a remarkably low water content. This finding contradicts earlier hypotheses suggesting Venus might once have harbored oceans or even supported conditions favorable for life. The key lies in volcanic activity. On Earth, volcanic eruptions release large amounts of water vapor, wh...

Hot Water on Ancient Mars? Tiny Martian Zircon Reveals Oldest Evidence Yet

Breaking News, Learning & Developments, Space

A groundbreaking study has uncovered the oldest evidence of water on Mars dating back 4.45 billion years, just shortly after the planet formed. The discovery, rooted in analysis of a Martian meteorite called NWA 7034, suggests Mars had hot water circulating in its crust, potentially creating environments suitable for microbial life. Key Findings Researchers from Curtin University identified a microscopic zircon grain in the meteorite, which contains minerals that could only form in the presence of water. This water, however, wasn’t just ordinary it was likely scalding hot, resembling conditions in hydrothermal vents or hot springs seen on Earth. “This is the earliest evidence of water on Mars, predating Earth’s oldest water signatures,” said geologist Aaron Cavosie of Curtin Unive...
