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

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 ...
Indian Astronomers Detect Ultraviolet Emissions from Novae in Andromeda

Indian Astronomers Detect Ultraviolet Emissions from Novae in Andromeda

Breaking News, Space
Astronomers from the Indian Institute of Astrophysics (IIA) have achieved a groundbreaking discovery, detecting far ultraviolet (FUV) emissions from novae in the Andromeda galaxy for the first time. Novae are transient astronomical phenomena marked by a sudden outburst of light from a star-like object, which gradually fades over time. Using data from the Ultraviolet Imaging Telescope (UVIT) aboard India's AstroSat, the IIA team identified these emissions while analyzing archival observations of Andromeda. AstroSat, India’s first dedicated space observatory, features UVIT as a key payload developed by IIA. During their study, the team uncovered ultraviolet emissions from 42 novae in Andromeda, including four captured during their explosive outburst phase. This discovery is significant...
Could a Rogue Planet Join Our Solar System? Scientists Explore the Possibility

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

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...
Mysterious Tessera Terrain on Venus Could Be the Remains of Giant Ancient Impacts

Mysterious Tessera Terrain on Venus Could Be the Remains of Giant Ancient Impacts

Breaking News, Climate Actions, Space
In the chaotic early days of the Solar System, planets endured a relentless barrage of cosmic collisions. Most of the rocky worlds including Mercury, Mars, and Earth's Moon still bear scars of these ancient impacts in the form of vast craters and impact basins. However, Venus has been a strange outlier, with scientists finding no evidence of large craters over 300 kilometers wide. This missing piece of Venus's violent past has puzzled researchers for years. A recent study now suggests that these long-sought impact structures may indeed exist on Venus but look very different from our expectations. Geologist Vicki Hansen of the Planetary Science Institute and her team propose that a peculiar formation called the Haastte-Baad Tessera could be Venus’s largest and oldest impact structure. Lo...
Astronomers Discover Tiny Exoplanet Orbiting Barnard’s Star, Just 6 Light-Years Away

Astronomers Discover Tiny Exoplanet Orbiting Barnard’s Star, Just 6 Light-Years Away

Breaking News, Disasters, Space
In a groundbreaking discovery, scientists have found a new exoplanet orbiting Barnard’s Star, the nearest single star to our Solar System, located just 5.96 light-years away. This small, rocky world, named Barnard b, has a mass of only 37% that of Earth, making it one of the smallest exoplanets ever detected. Although uninhabitable, the discovery marks a significant step toward finding Earth-sized planets scattered across the galaxy. Barnard b is incredibly close to its host star, completing an orbit every 3.15 days at just 0.02 astronomical units (AU) from the red dwarf. Despite Barnard’s Star being much cooler than our Sun, this proximity makes the planet too hot to sustain liquid water or life as we know it. However, the discovery is still a scientific marvel, as detecting such small...
