Humanity was built to explore — it’s not just in our nature, it’s in our DNA. Since our beginning we have traveled the planet searching for answers. Even before we finished discovering all there was on our planet, we began to look beyond. More specifically, we began to look up. We craved more knowledge; we wanted to understand our purpose and our place in a world of which we knew so little. We looked to the stars.
And what could the twinkling spheres of nuclear fusion billions of light years away teach us? They taught us our insignificance. And yet…
What if humanity managed to unite and as a global government we invested all our resources in finding and reaching a new planet?
Then the question becomes, what planet?
There aren’t any options in our solar system. Earth is the only planet in our solar system that’s in the habitable zone. The habitable zone is a certain distance away from a star where a given planet within that range of distance could have liquid water on its surface and potentially harbor life. Venus is too close to the sun and Mars is too far, but Earth on the other hand…
So if we can’t overcome climate change here on Earth or get to a new planet in time, is the human race doomed?
What I do know is that taking money away from NASA and other space agencies won’t save us. Yes, they still cost a lot of money. But are these costs even measurable? What does money mean in the face of scientific knowledge? How can we put a dollar value on curiosity and inspiration?
I’d like to conclude this series of articles with the story of the spacecraft Voyager 1.
Drug development and preclinical/clinical research have traditionally focused more on the male physiology and less on the female one. For example, more men are enrolled in clinical trials than women are and more male animals are used in biomedical research. This can be seen when looking at Figure 1.
When you imagine Earth from space, the picture above most likely resembles what you think of. We see this Earth in picture books and on TV. And that makes sense — this is Earth. Or, at least the Earth we’ve been taught about. But, in reality, this is what Earth used to look like.
In fact, today it looks something more like the animation below. As time passed, our need for telecommunications and weather satellites grew and launches occurred with increasing frequency. …
The same Doppler Effect that changes a siren’s pitch as it passes by an observer is used by planetary scientists to find exoplanets. Exoplanets orbit other stars outside our solar system. They are new worlds that may be habitable. The technique is known as Doppler spectroscopy, also referred to as the radial-velocity method, or the “wobble method.”
Spectrographs are high-resolution prism-like instruments that are able to separate light waves into different colors. When mounted on ground based telescopes they can be used to measure redshifts and blueshifts from astronomical objects extremely far away, such as a star. Scientists can also…
With five days on the clock, the Perseverance rover, built by NASA’s Jet Propulsion Laboratory in Southern California, is getting close to touching down. After being launched on July 30, Perseverance is scheduled to land in the Jezero Crater on Mars on February 18. Many events need to occur in a specific order during the final minutes of the rover’s nearly seven-month journey. The mission, aptly given the name, “Mars 2020” has four main objectives:
Have you ever wondered why the pitch of a siren drops while an ambulance passes by? Or wondered how scientists discovered that the universe was expanding? Well, believe it or not, the answers to those two questions are deeply related through something called the Doppler effect.
The Doppler effect can be observed for all types of waves, sound, light, even ocean waves. Both sound and light waves travel at a finite speed, though light is significantly faster and is the fastest thing that can move through space.
Born on November 29, 1803, in Salzburg, Austria, Christian Doppler was the person…
Common in science fiction, an antimatter powered rocket is not new. In fact, the propulsion system was first proposed by Eugen Sänger in 1953. When seen powering the Enterprise in “Star Trek” to speeds faster than light, using antimatter as an energy source seems completely in the realm of fiction. However, this futuristic technology may not be as far off as you think.
Let’s take a step back. What is antimatter?
There’s no trick, it’s exactly what it sounds like. The prefix ‘anti’ has Greek origin and means, “against, opposed to, opposite of, instead.” Antiparticles make up antimatter just as…
The human body is made up of trillions of cells. Most recent estimates put the number of cells at approximately 30 trillion. (Written out, that’s 30,000,000,000,000) Cells are the building blocks of all living things — they have many different parts, each with different functions.
Each cell has a set of instructions for making us, like a recipe book for the body. This set of instructions is called our genome and is made up of deoxyribonucleic acids, DNA.
DNA is a long molecule that holds our unique genetic code. It contains the instructions for making all the proteins in our…
