Comet Explodes Over Spain and Portugal: Everything We Know

What are comets?

Comets are celestial bodies that consist of ice, dust, and rocks. They revolve around the Sun on elliptical trajectories. As a comet approaches the sun, the ice in its core sublimates, or turns from a solid to a gas. This creates a coma, or cloud of gas and dust, around the nucleus. The solar wind then blows the coma away from the sun, forming a tail.

Skies over Spain and Portugal turn green after comet explosion

What causes comet explosions?

When a comet gets too close to the Sun, the heat can cause its nucleus to collapse. This can release large amounts of gas and dust, which can cause a spectacular explosion. The explosion seen over Spain and Portugal is thought to have been caused by a comet passing close to the Sun for the first time.

What are the consequences of a comet explosion?

Comet explosions can have a number of consequences for Earth. Dust and gas from the explosion could reflect sunlight, which could cool the Earth. An explosion can also release harmful chemicals into the atmosphere that can harm human health. However, comet explosions are relatively rare and usually do not pose a serious threat to Earth.

What do we still not know about comets?

There's still a lot we don't know about comets. Scientists are still working to understand their composition, formation, and behavior. They are also trying to determine what impact comets have on Earth.

Green Energy Costs to 2035: Prices & Trends

Green Energy Costs to 2035: Why Solar and Wind May Rise While Batteries Fall The global renewable energy revolution is accelerating. Governments, corporations, and households are investing billions in green energy systems. Yet a paradox is emerging: while the cost of generating solar power and wind energy may increase in the coming decade, battery storage prices are projected to decline significantly. Why is this happening? And what will it mean for consumers and investors by 2035? This evergreen analysis explores the economic forces shaping energy markets, provides price forecasts in U.S. dollars, and explains how global trends could redefine the cost of clean electricity. Why Green Energy Became So Affordable Over the past 15 years, renewable technologies have experienced dramatic cost reductions. According to the International Renewable Energy Agency (IRENA) , global weighted-average costs of solar photovoltaic electricity dropped by nearly 90% between 2010 an...

NASA’s Webb Uncovers Methane on Interstellar Comet 3I/ATLAS: A Cosmic Breakthrough

Imagine looking up at the night sky and realizing that the tiny, distant glimmer you see isn't just a remnant of our own cosmic neighborhood, but a visitor from a completely different solar system. The universe is whispering secrets to us, and for the first time in human history, we have the ears to listen. The James Webb Space Telescope (JWST) has just shattered our understanding of interstellar travelers by detecting methane on the comet 3I/ATLAS. This isn't just a chemical reading; it is a profound connection to the unknown, a bridge built of stardust and science that links our home to the mysterious voids between stars. The Arrival of an Interstellar Messenger For decades, astronomers dreamed of catching a glimpse of an object originating from outside our solar system. In 2017, we met 'Oumuamua, and later, 2I/Borisov. However, the discovery of 3I/ATLAS —often referred to as an interstellar comet—has provided us with a laboratory like no other. When this icy wanderer...

Unearthing the Secrets of Notre-Dame: The Archaeological Discovery of the Century

Imagine standing in the heart of Paris, surrounded by the echoes of modernity—the honking of taxis, the bustle of tourists, and the vibrant hum of a 21st-century metropolis. Now, imagine peeling back the layers of time, descending deep into the cool, silent earth beneath the scarred but resilient frame of Notre-Dame Cathedral. What lies beneath is not merely dirt and stone; it is a time capsule, a bridge across millennia, and quite arguably, the most significant archaeological find in modern French history. When the catastrophic fire of 2019 ravaged the cathedral, the world watched in heartbreak. But from the ashes, a new narrative emerged. As architects and historians prepared to reconstruct the spire, they stumbled upon secrets that had been buried for nearly two millennia. This is the story of the "dig of the century," where ghosts of the past finally meet the light of the present. Who Excavated the Site? The Guardians of History The monumental task of excavating ben...
