Everything discovered by JWST

Image
Image courtesy : NASA • The James Webb Space Telescope (JWST ) is the world's most advanced space observatory, dedicated to unraveling the secrets of the cosmos. Since its deployment, JWST has transformed our view of the universe, revealing previously unknown data about galaxies, exoplanets, and celestial events. Let's look at some of the telescope's most amazing finds. A New Window into the Early Universe . Image courtesy : NASA • One of JWST's key tasks is to investigate the early universe. Its strong infrared instruments discovered galaxies that formed just a few hundred million years after the Big Bang. JWST discovered some of the most ancient and distant galaxies, providing insight into the universe's origins. These findings help scientists comprehend how galaxies developed over billions of years.  Supermassive Black Holes : JWST unexpectedly detected supermassive black holes in the early universe. These observations call into question prevailing theories regar...

What Does It Smell Like in Space?

Image
 • When we think about space, we envision stars, planets, and an endless, silent void. Have you ever wondered what space smells like? It may appear unusual to raise this topic, especially since space is a vacuum with no air to transport smells. However, astronauts who have traveled to space report that it has a distinct aroma. Let us investigate this fascinating topic! Astronauts Talk About the Smell of Space • Astronauts who have been on spacewalks frequently mention the scent of space when they return to the safety of their spacecraft. They detect it on their spacesuits, helmets, and gear. Here is how some of them describe it.  Burnt Steak : According to several astronauts, space smells similar to burned beef.  Welding Fumes : Others liken it to the metallic smell of a welding flame.  Gunpowder : Some people compare the smell to the strong, smokey scent of gunpowder. Don Pettit, an astronaut, stated, "It's kind of like the smell of ozone, a faint acrid smell... it ...

The Top 10 Space Missions of 2024: A Closer Look

Image
• As we say goodbye to 2024, it's the ideal opportunity to reflect on humanity's remarkable progress in space exploration. This year has been full with historic accomplishments, ground-breaking missions, and discoveries that have broadened our understanding of the universe.  • Let's take a deeper look at the top ten space missions of 2024, each one demonstrating human ambition, curiosity, and drive to explore the unknown.  1. Chandrayaan-3, India's Moon mission . • India's Chandrayaan-3 mission made news in 2024 for successfully landing near the Moon's south pole, a previously unexplored region. The mission's goal was to investigate the lunar surface and research its composition, with an emphasis on the south pole, which has the potential for water ice.   Highlights : The Pragyan rover conducted tests and transmitted significant data on lunar materials to the global scientific community.  Why It's Special : This mission made India the first country to la...

The Venus Orbiter Mission (VOM): ISRO's upcoming mission

Image
• India's space exploration program, led by the Indian Space Research Organisation (ISRO), has continually pushed the boundaries with its ambitious missions • Following significant triumphs such as Chandrayaan and Mangalyaan, ISRO now turns its attention to Venus with the impending Venus Orbiter Mission (VOM), which is scheduled for March 2028. Let's go into the specifics of this historic mission, which attempts to solve the riddles of our planetary neighbor. Why Venus ?  • Venus is sometimes referred to as Earth's twin due to its comparable size and composition, although its atmosphere and surface conditions are starkly different from ours.  • Venus, with surface temperatures reaching 470°C, a dense atmosphere dominated by carbon dioxide, and sulfuric acid clouds, is an ideal laboratory for studying greenhouse effects, planetary evolution, and atmospheric dynamics. Exploring Venus can help scientists figure out why two similar planets formed so differently. Mission Objecti...

What If We Could Travel to the Past and Kill Our Ancestors?

Image
• Time travel has long been one of the most intriguing concepts in science fiction. It opens the door to limitless possibilities, both thrilling and terrible. But what if we could travel back in time and kill our ancestors? This isn't simply a weird idea; it's a well-known thought experiment termed the "grandfather paradox." Let's take a look at this mind-bending topic in plain terms. The Grandfather Paradox: Breaking the Chain • Imagine this: You invent a time machine, go back in time, and accidentally (or intentionally) kill your grandfather before he meets your grandmother. If your grandfather dies, your parents wouldn’t be born. And if your parents aren’t born, you wouldn’t exist. But if you don’t exist, how could you have traveled back in time to kill your grandfather in the first place? • This is the paradox. It creates a loop of impossibility where your actions in the past contradict your very existence. Could time travel actually work this way? • Scientist...

Space Exploration V/S. Ocean Exploration

Image
  • The world around us is riddled with secrets, both above and below. While we marvel at the heavens, we frequently overlook the marvels hiding beneath the waters of our own planet.  • Space exploration and ocean exploration are two of humanity's most thrilling adventures. But how do they compare? Let's delve further and look beyond the stars to investigate this fascinating subject. 1. Why should we explore space?  • Space has always inspired us because of its grandeur. It is the final frontier, presenting limitless opportunities to learn about the universe, our origins, and potentially our future.  • Here are a few reasons why space exploration is important:  Understanding the Universe : Studying space teaches us about stars, planets, black holes, and galaxies.  Missions such as Mars Rovers and the James Webb Space Telescope search for signs of life beyond Earth .  Space flights have resulted in technological advancements such as GPS, satellite com...

What if Time Travel Becomes Possible?

Image
  • Imagine waking up one day and discovering you can travel to the past or future. So, what would you do first? Going to see the dinosaurs? Witness humanity's future? Or perhaps you want to correct a past mistake? We've always been captivated by time travel, which appears in books, movies, and TV series. But what if it were real? Let's look at what might happen if time travel become possible. How might time travel work?  Scientists frequently discuss two major concepts about time travel:  1. Traveling to the Future : Einstein's theory of relativity makes this possible to some extent. When you travel at the speed of light, time slows down in comparison to those on Earth. In principle, you could travel into the future.  2. Traveling to the Past : This is difficult. Scientists believe that wormholes, which are shortcuts through space and time, may allow for backward travel. However, we lack the capability to construct and govern wormholes. The Benefits of Time Travel ...
