Introducing the Q-Drive: A concept that offers the possibility of interstellar flight

If Breakthrough Starshot is tackling the question of velocities at a substantial percentage of lightspeed, what do we do about the payload question? A chip-sized spacecraft is challenging in terms of instrumentation and communications, not to mention power. Enter Jeff Greason’s Q-Drive, with an entirely different take on high velocity missions within the Solar System […]

New LIGO Events Demolish The Idea Of A ‘Mass Gap’ Between Neutron Stars And Black Holes

On Monday, March 16, 2020, astrophysicist Carl Rodriguez expressed a sentiment echoed by gravitational wave physicists all across the world: NOT NOW LIGO! Just minutes earlier, the LIGO collaboration sent out an alert suggesting that it had just detected another gravitational wave event, the 56th candidate detection since starting up its latest data-taking run in […]

Heart, Eye Studies in Space as Next Crew Nears Launch

NASA astronaut Andrew Morgan retrieves gut microbe samples from a science freezer for an experiment to understand how microgravity affects microbes that impact astronaut health. Cardiac research and 3D bioprinting aboard the International Space Station today are helping NASA improve health for humans in space and on Earth. The three Expedition 62 crewmembers also participated […]

How Researchers Produce Sharp Images of a Black Hole

In April of 2019, the Event Horizon Telescope collaboration history made history when it released the first image of a black hole ever taken. This accomplishment was decades in the making and triggered an international media circus. The picture was the result of a technique known as interferometry, where observatories across the world combined light […]
