Most of us have viruses sleeping inside us, and spaceflight wakes them up

Human spaceflight seems all the more remarkable when you consider the fact that our bodies didn’t evolve for space. We suffer in major ways as a result of microgravity and living in confined quarters hundreds of miles above the surface of the planet. Even our our immune systems take a hit, leaving us more susceptible to infection and disease as we spend more time in space.

Check Out This Incredible X-Ray ‘Superbubble’ That’s Nearly 5,000 Light-Years Wide

This incredible image shows a pair of “nuclear superbubbles,” one over 4,900 light-years across and the other over 3,500 light-years. They’re emanating from the center of the galaxy NGC 3079, likely the result of a central black hole consuming matter and spewing it back out.

A Collision With Another Planet May Have Seeded Earth With the Ingredients for Life

New research suggests that much of the material that made life possible on Earth arrived after a cataclysmic collision between our planet and a Mars-sized object billions of years ago—likely the same collision that produced the Moon, the scientists say. Continue reading A Collision With Another Planet May Have Seeded Earth With the Ingredients for Life

Astronomers detect more mystery radio bursts from beyond the Milky Way

Sure enough, astronomers have discovered even more of those mysterious fast radio bursts from outside the Milky Way galaxy. Scientists using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope have detected 13 different radio bursts, including six repeat bursts from the same location in a galaxy 1.5 billion light years away. Each of those bursts represents about 25 million times more energy than the Sun, and they were collected at the lowest frequencies yet (400MHz to 800MHz).

Gaze in Awe at Hubble’s Most Detailed View of the Triangulum Galaxy

Usually when astronomers talk about our neighboring galaxy, they’re talking about Andromeda, which is a cozy 2.5 million light-years away. But just a little farther—okay, 500,000 light-years farther—is another spiral galaxy, the third largest in our local group. Hubble has just released its most detailed view yet of that galaxy, which is known as Triangulum (can you see why?).
