Study reveals new details on what happened in the first microsecond of Big Bang

Posted by in categories: alien life, evolution, particle physics

Researchers from University of Copenhagen have investigated what happened to a specific kind of plasma—the first matter ever to be present—during the first microsecond of Big Bang. Their findings provide a piece of the puzzle to the evolution of the universe, as we know it today.

About 14 billion years ago, our changed from being a lot hotter and denser to expanding radically—a process that scientists have named the Big Bang.

And even though we know that this fast expansion created particles, atoms, stars, galaxies and life as we know it today, the details of how it all happened are still unknown.

A rare glimpse of a star before it went supernova defies expectations

Posted by in category: alien life

A rare glimpse of a star before it exploded in a fiery supernova looks nothing like astronomers expected, a new study suggests.

Images from the Hubble Space Telescope reveal that a relatively cool, puffy star ended its life in a hydrogen-free supernova. Until now, supernovas without hydrogen were thought to originate only from extremely hot, compact stars.

The discovery “is a very important test case for stellar evolution,” says Sung-Chul Yoon, an astrophysicist at Seoul National University in South Korea, who was not involved in the work. Theorists have some ideas about how massive stars behave right before they blow up, but such hefty stars are scant in the local universe and many are nowhere near ready to go supernova, Yoon says. Retroactively identifying the star responsible for a supernova provides an opportunity to test scenarios of how stars evolve right before exploding.

Mushrooms on Mars: Do These Images Show Proof of Life on Mars?

Posted by in category: alien life

Scientists believe these photos show mushrooms on mars—and proof of life.


Could there be mushrooms on Mars? In a new paper, an international team of scientists from countries including the U.S., France, and China have gathered and compared photographic evidence they claim shows fungus-like objects growing on the Red Planet.

China rocket debris likely plunged into the Indian Ocean near the Maldives, says China’s space agency

Posted by in categories: alien life, engineering

Debris from an out-of-control Chinese rocket likely plunged into the Indian Ocean, just west of the Maldives, on Saturday night ET, China’s space agency said.

Most of the huge Long March 5B rocket, however, burned up on reentering the atmosphere, the China Manned Space Engineering Office said in a post on WeChat.

It was unclear if any debris had landed on the atoll nation.

Scientists Claim to Spot Fungus Growing on Mars in NASA Rover Photos

Posted by in category: alien life

The team went so far as to say that “black fungi-bacteria-like specimens also appeared atop the rovers.”

They didn’t stop there: the team also examined photos taken by NASA’s HiRISE, and found evidence for “amorphous specimens within a crevice” that “changed shape and location then disappeared.”

“It is well established that a variety of terrestrial organisms survive Mars-like conditions,” the team concludes. “Given the likelihood Earth has been seeding Mars with life and life has been repeatedly transferred between worlds, it would be surprising if there was no life on Mars.”
