## NASA Confirms: Living Aboard The International Space Station Changed Scott Kelly’s DNA

Although it is almost a given that the DNA that we are all born with does not change throughout our lives, there is new evidence that could go against that belief as astronaut Scott Kelly’s DNA changed after spending time in space. U.S. astronaut Scott Kelly recently spent a whole year of his life living

## We Now Have An Idea About What Jupiter’s Interior Looks Like And It’s Incredible

NASA’s Juno spacecraft, that has been orbiting Jupiter since 2016, has sent us back some incredible information. The interior of Jupiter has been a mystery to us since we first started studying Jupiter in the 1600’s, but now we actually have an idea about what Jupiter’s interior is like. The results of the study were

## Integer Aperture Estimation In The Presence Of Biases

Integer aperture estimation, also called integer ambiguity resolution, is a critical step to realized fast and precise global navigation satellite system (GNSS) positioning. It is a process which projects a float ambiguity to an integer ambiguity and then judges whether to fix that integer. Decades of research offer many projection methods. Efficiency and success rate

## Predicting CMEs And Solar Flares

The two biggest energy explosions in our Solar System are solar flares and coronal mass ejections (CMEs). These eruptions can have a serious effect on our modern society’s way of life. A main disparity between the enormous eruptions is the scale on which they appear. A flare is a localized sudden brief brightening on the

## Celestial Mechanics, Relative Equilibria, And Many Difficult Problems

Celestial mechanics is a branch in the intersection of mathematics and physics, where the main goal is to describe the motion of any number of bodies (in a three dimensional space), characterized by some physical attributes like mass or electric charge and with some specific geometrical form, which interact each other by a law dependent

## Finding Time For Evolution

Time is a concept that is taken for granted in most areas of human life. It is treated casually without much thought, and we only seem to run into trouble when trying to take the concept apart to see what exactly makes it tick. But tearing apart concepts is what theoretical physicists do best, and

## NASA Believes Saturn’s Moon Enceladus Could Have Alien Life

As most might know, the gas giants in our solar system all have a multitude of moons and natural satellites surrounding. Saturn has a whopping 62 moons, including the moon Enceladus, which has recently been found to have the possibility of harboring life. If so, this could be one of the most important discoveries of

## Finding Solutions To Contradictions In Relativity And Quantum Mechanics

The twentieth century gave birth to two of the most important Physics theories of nowadays: Special/General Relativity and Quantum Mechanics. These two theories have accompanied humanity in the questions of what is space, what is time and what is matter; they have taught us to characterize these entities. In spite of their great successes, not

## Sources Of The High-energy Tail Of Solar Wind

The heliosphere is filled with hot dilute plasma known as solar wind. Due to thermal collisions, the velocity distribution of ions follows a Maxwell distribution. The measured energy spectrum of the ions above the peak at about 1 keV/nucleon, however, is not falling off as rapidly as the Maxwell distribution would predict. Instead, the spectrum

## NASA’s Mars Opportunity Rover Exceeds All Expectations: Reaches 5,000 Sols

The Mars rover Opportunity has reached a milestone. February 15, 2018, marked 5,000 sols (Martian days) that Opportunity has been on Mars when its original mission was only supposed to last 90 sols. The Opportunity was one of the first rovers that NASA sent to Mars and it is now part of a much bigger plan
