Humans in Space!

What happens when astronaut teams don’t get along?

Professor Contractor Noshir knows how to help you get along better with your coworkers. He studies the interpersonal dynamics of crews in extreme environments,…


Microbes from extreme environments help us study space

Space is a hostile place. It has numerous stressors which make it seem impossible for Earth-like life to thrive there. Some of these stresses include harmful…


Building a better spacesuit for a trip to Mars

An intra-vehicular space suit and a storm shelter will help protect astronauts from radiation during a trip to Mars. Infusing the suit material with graphene…


How does the human body react to being in space?

Is going to space safe for human health? Two astronauts, who were twins, volunteered for a research study to look at how the body changes when it goes into…

1.76 billion light years away, two black holes smashed into one another, bearing one huge black hole the size of 53 suns. The explosion from this merger created enormous distortions in spacetime, known as gravitational waves. These gravitational ripples have been flying through the universe, and finally visited Earth.…

“How moving!” is what the Earth would say when it comes into contact with gravitational waves. Albert Einstein’s general theory of relativity predicted these gravitational waves. These waves are disturbances in space caused by very massive objects and events. LIGO, (Laser Interferometer Gravitational-Wave…

There is overwhelming evidence to support the existence of dark matter, but its existence is still a mystery to physicists. A method called Indirect detection remains one of our best hopes for experimentally detecting particles of the elusive Dark Matter (DM). The idea behind indirect detection is that dark matter…

Our Sun is the nearest star to us. We have worshipped it, bathed in its light, and, of course, studied it. Scientists regularly use our Sun as a model for how similar stars should work. Thus, scientists develop the theory of stellar evolution (the study of the life cycles of stars) by observing our sun. Curiously,…

Radio astronomers working with a radio dish telescope detected something a bit unusual. They were seeing a very fast radio burst, faster and more irregular than any signal in the history of radio astronomy. This radio burst was coming at very short time scales, lasting just a few milliseconds. The signal was irregular,…

Trains have been the fundamental backbone of transportation and shipping for a few hundred years. Despite the ubiquity of trains, the details of their workings are a bit of a mystery. Trains have come about as more of a feat of engineering than one of science. Thus, the detailed scientific theory of trains has remained…

Large stars and planets in space have intense gravity. The gravity of these large celestial bodies is so strong, that they actually warp the empty space around them. Also, in space, time progresses differently when near celestial bodies. Because of these effects on space and time, space is regarded as a space-time…

Our understanding of astrophysics states that we should be seeing co-orbiting planets when astronomers look through their telescopes. Co-orbiting planets are planets of roughly similar size that have overlapping orbits around their host star. These two planets orbit so closely to each other that they influence the…

51 Pegasi b is a roughly jupiter-sized planet around a star pretty similar to our sun. This planet has been part of astronomy conversations before, as it is a huge planet with a really small orbit; this planet orbits around its star only every 4 days. For comparison, Earth orbits the sun every 365 days. One way of…
