Oumuamua is an object that passed through the solar system in 2017 and was initially thought to be an asteroid. However, its unusual shape and trajectory led some scientists to suggest that it could be an alien spacecraft.

Scientists from the SETI Institute (Search for Extraterrestrial Intelligence) proposed that Oumuamua could be a lightsail, a type of spacecraft that uses the pressure of sunlight to propel itself through space. They proposed that Oumuamua might be a discarded lightsail from an alien civilization.

However, most scientists believe that Oumuamua is a natural object, possibly a fragment of a larger body that was ejected from its own star system. Studies of Oumuamua’s properties, such as its size, shape, and rotation, suggest that it is a fragment of a larger body that was ejected from its own star system. While the possibility of Oumuamua being an alien spacecraft cannot be ruled out, it is considered as highly unlikely as per the current understanding of the data available.

Vast volcanic eruptions may have turned Venus from paradise (68 to 122 degrees Fahrenheit) into hell. The surface temperature is a sweltering 867 degrees Fahrenheit (464 degrees Celsius), hot enough to melt lead, and there’s a crushing pressure of 90 atmospheres underneath the dense clouds of carbon dioxide laced with corroding sulfuric acid. Venus is a victim of a runaway greenhouse effect.

After just under a year in space, astronaut Scott Kelly’s gene expression changed significantly and it’s different to his identical twin brother’s DNA. A new NASA statement suggests the physical and mental stresses of Scott Kelly’s year in orbit may have activated hundreds of “space genes” that altered the astronaut’s immune system, bone formation, eyesight and other bodily processes. While most of these genetic changes reverted to normal following Scott Kelly’s return to Earth, about 7 percent of the astronaut’s gene expression remained altered — and it may stay that way permanently.
