The Fermi Paradox Has An Incredibly Simple Solution

It’s possibly the most famous question in all of science — where is everyone? Join us today for deep dive into Fermi Paradox. 🌏 Get exclusive NordVPN deal here ➵ https://NordVPN.com/coolworlds It’s risk free with Nord’s 30 day money-back guarantee!✌

The Fermi Paradox has been a topic of keen debate amongst scientists, astronomers and the rest of us for more than seven decades. We can’t resist the urge to speculate about aliens! But what is the paradox even really about? What explanations have been offered? Today, we explore this famous question, and offer a mind-shifting explanation.

James Webb Space Telescope makes 1st detection of diamond-like carbon dust in the universe’s earliest stars

The James Webb Space Telescope has detected the earliest-known carbon dust in a galaxy ever.

Using the powerful space telescope, a team of astronomers spotted signs of the element that forms the backbone of all life in ten different galaxies that existed as early as 1 billion years after the Big Bang.

The detection of carbon dust so soon after the Big Bang could shake up theories surrounding the chemical evolution of the universe. This is because the processes that create and disperse heavier elements like this should take longer to build up in galaxies than the age of these young galaxies at the time the James Webb Space Telescope (JWST) sees them.

Our search for extraterrestrial life assumes alien life based on water and carbon, but could there be biochemistries based on other substances?

Is there life on Venus? Report confirms more phosphine

(NewsNation) — Astronomers have once again found a potential signal of life in the clouds of Venus.

The controversial observation of molecules of phosphine was first reported in 2020. Phosphine, comprised of hydrogen and phosphorus, is a gas on Earth that is only associated with life.

Three years later, “extensive additional detections” of the molecules were presented at the National Astronomy Meeting 2023 at Cardiff University in Wales, UK, according to a Forbes report.

‘Hundred times’ more probability of finding water on exoplanets, says new study

Rutgers University scientists believe there might be many more Earth-like exoplanets with liquid water.

Are we alone in this vast universe? Are there planets out there that harbor liquid water and ideal conditions for life to thrive?

These are some of the major questions that space scientists hope to find answers to. However, in order to answer these big questions, it is necessary to get into the nitty-gritty of what may allow water to sustain itself on other distant planets.

NASA’s Juno Spacecraft Just Captured A Spooky Green Lightning Flash On Jupiter

NASA’s Juno spacecraft recently captured this spooky green flash of lightning in a massive storm swirling near Jupiter’s north pole.

The tremendous burst of lightning glows bright against the dark gray vortex of the storm, even from Juno’s vantage point 19,900 miles above the tops of Jupiter’s clouds. Lightning often flashes between the clouds of stormy Jupiter’s higher latitudes, especially in the north. NASA’s Juno spacecraft is helping shed light on the gas giant’s wild alien weather.

Citizen scientist Kevin M. Gill processed the image from Juno’s raw data.

Ariane 5 aces final launch, paving the way for debut of Ariane 6

And Europe currently has no operational rocket at its disposal.

Europe’s workhorse Ariane 5 rocket aced its final launch, as its maker Arianespace now looks ahead to the debut of its long-delayed Ariane 6. The Ariane 5 rocket took off from the European Spaceport at Kourou, French Guiana, at 6 p.m. ET, July 5. Arianespace and The European Space Agency (ESA) had originally intended for the final launch of Ariane 5 to take place after the debut of Ariane 6.

A long string of delays to Ariane 6, however, means that Europe currently has no operational rocket, and it likely won’t have one until next year.
