Mysterious dark streaks on Mars were actually made by BOILING water


Here’s something you’d never expect to happen in a place with average temperatures of -67 degrees Fahrenheit — Mars’ flowing water is boiling!

The prodigal son returns: tailless comet from Earth’s distant past might hold primordial secrets

Artist impression of the first rocky object found in the Oort cloud.

A rocky body that’s neither exactly a comet nor an asteroid, may hold some interesting clues about how the planets in the solar system formed, including Earth. The tailless so-called Manx comet, named so after a breed of cats without tails, originates from the Oort cloud — a shell of icy objects that exist in the outermost reaches of the solar system. Although it’s more than a trillion miles away, this Manx comet is likely made of the same stuff that eventually coalesced to form Venus, Mars or even Earth.

Take me to Mars: NASA signs $67M contract for new solar electric propulsion engine

Advanced solar electric propulsion will be needed for future human expeditions into deep space, including to Mars. Shown here is a 13-kilowatt Hall thruster being evaluated at NASA’s Glenn Research Center in Cleveland. Hall thrusters trap electrons in a magnetic field and use them to ionize the onboard propellant. It uses 10 times less propellant than equivalent chemical rockets.

A company called Aerojet Rocketdyne has won a $67 million contract from NASA to design and develop an advanced electric propulsion system that could power complex missions to asteroids and even to Mars.

Lonely planet found in a family of stars

A young, free-floating world sits alone in space in this illustration. The object, called WISEA J114724.10?204021.3, is thought to be an exceptionally low-mass "brown dwarf," which is a star that lacked enough mass to burn nuclear fuel and glow like a star. Image credit: NASA/JPL-Caltech

NASA astronauts have discovered a lonely planetary-like mass floating on its own, without a solar system. Imagine a galaxy, riddled with countless solar systems. Then zoom in slowly on a solar system – how do you picture it? There’s probably a star at the center, and several planets around it. That’s generally where we feel planets should be, rotating around

There’s confidence that reproducing in space is indeed possible, based on previous research. The most recent experiment made by Chinese scientists, for instance, proved that mammalian embryos can develop in microgravity.
