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

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 ...

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...

ISRO Successfully Launches ESA’s Proba-3 Satellites, Advancing Solar Research

Breaking News, Space, Tech

In a major milestone for space exploration, the Indian Space Research Organisation (ISRO) successfully launched the European Space Agency’s (ESA) Proba-3 satellites aboard the PSLV-C59 rocket. This groundbreaking mission, a collaboration between ISRO and ESA, is expected to revolutionize the study of the Sun's corona and solar wind, marking a new chapter in solar physics. Proba-3 focuses on the Sun's corona, the outermost layer of the Sun's atmosphere that is inexplicably hotter than its surface. The mission aims to analyze the solar wind a stream of charged particles emitted by the Sun and its impact on space weather conditions. Former ISRO scientist PV Venkitakrishnan highlighted that Proba-3’s advanced design will replicate the effects of a total solar eclipse, offering continuous ob...

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...

Jupiter to Light Up the Night Sky in a Rare Celestial Event on December 7

Breaking News, Space

A spectacular astronomical event is set to captivate stargazers on December 7 as Earth aligns directly between the Sun and Jupiter. This rare occurrence, known as Jupiter’s Opposition, will illuminate the largest planet in our solar system like never before. Throughout the night, Jupiter will dominate the skies, its brilliance unmatched and its details visible to anyone with even a basic telescope or binoculars. During this phenomenon, Jupiter’s sunlit side will face Earth in its entirety, creating a breathtaking view that resembles the full moon in its glory. As Earth’s faster orbit brings it into perfect alignment with the gas giant, the planet will appear larger and brighter than at almost any other time. The result is a celestial show that will keep skywatchers enchanted from dusk t...

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...
