Evidence the universe might not be expanding

Posted by in categories: alien life, information science

Dismantling the belief in a static universe, Edwin Hubble’s revolutionary observations in the 1920s laid the groundwork for our understanding of a continually expanding cosmos. However, we must seek to reconcile this theory with observations that are consistent with a non-expanding universe, writes Tim Anderson.

You have been taught that the universe began with a Big Bang, a hot, dense period about 13.8 billion years ago. And the reason we believe this to be true is because the universe is expanding and, therefore, was smaller in the past. The Cosmic Microwave Background is the smoking gun for the Big Bang, the result of a reionization of matter that made the universe transparent about 300–400,000 years after the Big Bang.

How did we go from Einstein modifying his equations to keep the universe static and eternal, which he called the biggest blunder of his life, to every scientist believing that the universe had a beginning in 10 years? It all started with astronomer Edwin Hubble using the most powerful telescope at the time on Mount Wilson in California. At the time, in the 1920s, scientists believed that the Milky Way galaxy was the totality of the universe. Objects in the night sky like Andromeda that we now know are galaxies were called “nebulae”.

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

Posted by in categories: alien life, chemistry, evolution

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.

Is there life on Venus? Report confirms more phosphine

Posted by in category: alien life

(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

Posted by in category: alien life

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

Posted by in categories: alien life, climatology

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.
