The Genesis Project: New life on exoplanets

exoplanets

exoplanets

Can life be brought to celestial bodies outside our solar system, which are not permanently inhabitable? A new essay that has been published is trying to deal with this question. Over the last several years, the search for exoplanets has shown that very different types exist leading to new questions and a variety of possible answers.

Scientists at Washington State University and the University of Idaho are helping students figure out how to farm on Mars, much like astronaut Mark Watney, played by Matt Damon, attempts in the critically acclaimed movie “The Martian.” Washington State University physicist Michael Allen and University of Idaho food scientist Helen Joyner teamed up to explore the challenge. Their five-page study guide was published the day the movie premiered earlier this month.

Research investigates whether solar events could trigger birth defects on Earth

Studies find airplane crews at high altitude are exposed to potentially harmful levels of radiation from cosmic rays. But could these cosmic rays pose hazards even at sea level? In recent years, research has suggested congenital birth defects down on Earth’s surface could be caused by these “solar particle events” — spikes in cosmic rays from the sun that touch off the northern lights and sometimes hamper communications or the electric power grid.

Dead galaxies in Coma Cluster may be packed with dark matter

Galaxies in a cluster roughly 300 million light years from Earth could contain as much as 100 times more dark matter than visible matter, according to an Australian study. The research, published today, used powerful computer simulations to study galaxies that have fallen into the Coma Cluster, one of the largest structures in the Universe in which thousands of galaxies are bound together by gravity.

Study finds metal foams capable of shielding X-rays, gamma rays, neutron radiation

metal foam

Research from North Carolina State University shows that lightweight composite metal foams — like the one pictured here — are effective at blocking X-rays, gamma rays and neutron radiation, and are capable of absorbing the energy of high impact collisions. The finding means the metal foams hold promise for use in nuclear safety, space exploration and medical technology applications.

While mass media was busy misquoting Stephen Hawking and arguing about black holes, astrophysicists have been hard at work trying to solve still unanswered questions about them. Now a team has not only proven that a supermassive black hole exists in a place where it isn’t supposed to be, but in doing so have opened a new door to what things were like in the early universe.
