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.

Salty Water Under the Surface of Mars Could Have Enough Oxygen for Life

Mars may have a hostile, dusty exterior bathed in dangerous radiation, but a new study suggests that it’s possible life could exist under that inhospitable crust. Pockets of salty water with enough dissolved oxygen to support life may be present in certain parts of the planet, according to a new paper published in the journal Nature Geoscience.

Explorers Will Face Dangerous Amounts of Radiation On Their Trip to Mars

Traveling to Mars is the next great step in humanity’s space journey. In Hollywood, the recent movie The Martian and television series The First present reaching the Red Planet as more of a near-term logistics challenge rather than a pie-in-the-sky space dream. NASA is currently orienting itself toward a “Moon to Mars” Mission, but the technical hurdles facing a Mars mission are still massive. One of the most difficult challenges is dealing with the dose of radiation any interplanetary astronauts would face. Meghan Bartels at Space.com reports that new data from the European Space Agency (ESA) has refined our model for radiation during the journey to and from Mars, and it doesn’t look good.
