Researchers discover how space travel weakens astronauts’ immune systems

A new study published June 7 in the journal Scientific Reports found that space travel weakens the immune system by causing the abnormal activation of cells that suppress immune responses. Researchers from the University of California, San Francisco and the Stanford University School of Medicine arrived at this finding after exposing human blood samples to simulated weak gravity, or microgravity. They then used … Continue reading Researchers discover how space travel weakens astronauts’ immune systems

Weak spot in magnetic field may be caused by an ancient planet buried inside the Earth

There is a weak spot in the Earth’s magnetic field, and some scientists believe it may have been caused by the remnants of an ancient planet that impacted the Earth billions of years ago. The Earth has a protective geomagnetic field that shields the planet from deadly solar radiation. This field is generated by a process that … Continue reading Weak spot in magnetic field may be caused by an ancient planet buried inside the Earth

Earth may have been a “water world” three billion years ago, new research suggests

Earlier studies have suggested that the Earth was once engulfed by water and had few or no landmasses at all some three billion years ago. A recent analysis of the Earth’s mantle provides evidence in support of that idea. Published in the journal AGU Advances, it suggested that back when the planet was a molten ball of magma, its mantle held far less … Continue reading Earth may have been a “water world” three billion years ago, new research suggests

Meteorite in Michigan may hold clues to origin of life on Earth

According to a new study a meteorite that fell in Michigan in 2018 may contain clues to the origin of life on Earth. Published in the journal Meteoritics & Planetary Science, the study said that the meteorite contained a good amount of organic matter. Researchers from the U.S., Canada, Germany and China were able to pick up and examine the rock … Continue reading Meteorite in Michigan may hold clues to origin of life on Earth

Scientists use nanoparticles as an alternative propulsion method for small spacecraft

Propellant is one of the most important things that any spacecraft needs to carry – without it, a spacecraft will be unable to move or change course. This is why spacecraft tend to carry a lot of it on board. Carrying propellant, however, brings its own set of problems. Not only is the chemical highly flammable, … Continue reading Scientists use nanoparticles as an alternative propulsion method for small spacecraft

Research: Strange behavior of Earth’s magnetic field in the South Atlantic believed to be symptoms of an event that repeats every few million years

The Earth is protected from solar wind — a stream of charged particles from the sun — by its geomagnetic field. But this protective barrier is weak in certain areas, particularly south of the Atlantic Ocean. Called the South Atlantic Anomaly (SAA), this area makes it easier for solar wind and other cosmic rays to enter the … Continue reading Research: Strange behavior of Earth’s magnetic field in the South Atlantic believed to be symptoms of an event that repeats every few million years

Space cooties: Should astronauts be worried about fungi on space stations?

Bacteria and viruses are not the only tiny hitchhikers during outer space that might endanger the health of astronauts. Recently, Belgian researchers brought up concerns about microscopic fungi living aboard space stations and spacecraft, especially the upcoming missions to the moon and Mars. Experts know very little about the potential pathogenic properties of these microorganisms. The … Continue reading Space cooties: Should astronauts be worried about fungi on space stations?

Devastating solar storms are much more common than previously believed, warn scientists… and Earth is in the cross hairs

Researchers have found evidence that a massive solar storm enveloped Earth 2,600 years ago. Now, they warn that similar space weather phenomena of the same magnitude could happen again. Since the last such event in 1859, humans have come to rely on electricity. Another solar storm of that size and power would cause chaos around the world. … Continue reading Devastating solar storms are much more common than previously believed, warn scientists… and Earth is in the cross hairs

NASA admits that climate change occurs because of changes in Earth’s solar orbit, and NOT because of SUVs and fossil fuels

For more than 60 years, the National Aeronautics and Space Administration (NASA) has known that the changes occurring to planetary weather patterns are completely natural and normal. But the space agency, for whatever reason, has chosen to let the man-made global warming hoax persist and spread, to the detriment of human freedom. It was the year 1958, to be … Continue reading NASA admits that climate change occurs because of changes in Earth’s solar orbit, and NOT because of SUVs and fossil fuels

Earth’s ozone hole rapidly shrinking following ban of ozone depleting chemicals

About three decades have passed since scientists made the devastating discovery that a massive hole had developed in the Earth’s ozone layer – the shield that protects us from the sun by absorbing most of its ultraviolet radiation – right over Antarctica. Recognizing the immensely dangerous potential of the situation, most of the world’s countries … Continue reading Earth’s ozone hole rapidly shrinking following ban of ozone depleting chemicals
