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

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...

Why Does Delhi Flood? The Answer Lies in Our Urban Stormwater Management

Breaking News, Disasters, Idea & Innovations

Every year, we witness flooding in our large metropolises and most state capitals. Normally, Delhi is in the news for flooding due to the overflowing of the Yamuna River when large volumes of water are released from the Tajewala dam upstream. However, on June 28, 2024, we witnessed flooding from a high rainfall episode in south Delhi. What explains the frequent in-situ urban flooding in Delhi? This happened in Bengaluru and Lucknow in 2023 as well. High rainfall and climate change are undoubtedly a reality. But is it just that, or something more? To understand the recent flooding in Delhi, let us first understand why 15 minutes of rainfall causes flooding on the Mehrauli-Badarpur road (MB Road) in south Delhi. What does this have to do with understanding Delhi’s urban stormwater managem...

Climate Crisis and the Lengthening of Days: The Impact of Melting Polar Ice Caps

Breaking News, Environment

A recent study highlights a lesser-known consequence of the climate crisis: the melting of polar ice caps is causing Earth to spin more slowly, increasing the length of days at an unprecedented rate. Published in the Proceedings of the National Academy of Sciences, the paper reveals how water flowing from Greenland and Antarctica is resulting in more mass around the equator, a phenomenon co-author Surendra Adhikari of NASA's Jet Propulsion Laboratory likens to a figure skater extending their arms during a spin, slowing down their rotation. While Earth is often thought of as a sphere, it is more accurately described as an "oblate spheroid," bulging around the equator much like a satsuma. This shape is constantly changing due to various factors such as daily tides, tectonic plate movement...

New Study Reveals Ancient Origins of LUCA Early Life on Earth

Breaking News, Climate Actions, Idea & Innovations

Once upon a time, Earth was a barren planet. That changed dramatically when, out of the chemistry present during its early history, something began to squirm processing matter to survive, reproduce, and thrive. The nature of that something, and when it first appeared, have puzzled humanity for as long as we have been able to ask, "What am I?" Now, a groundbreaking study has provided some answers, revealing that life emerged surprisingly early in Earth's history. By analyzing the genomes of organisms alive today, scientists have determined that the last universal common ancestor (LUCA) the first organism that spawned all current life on Earth emerged as early as 4.2 billion years ago. Given that Earth is around 4.5 billion years old, this suggests that life began when the planet was s...
