Astronomers have revealed new evidence about the properties of the giant bubbles of high-energy gas that extend far above and below the Milky Way galaxy’s center.

In a study recently published in Nature Astronomy, a team led by scientists at The Ohio State University was able to show that the shells of these structures—dubbed “eRosita bubbles” after being found by the eRosita X-ray telescope—are more complex than previously thought.

Although they bear a striking similarity in shape to Fermi bubbles, eRosita bubbles are larger and more energetic than their counterparts...

No matter where we go in the universe, we’re going to need water. Thus far, human missions to Earth orbit and the moon have taken water with them. But while that works for short missions, it isn’t practical in the long term. Water is heavy, and it would take far too much fuel to bring sufficient water to sustain long-term bases on the moon or Mars. So we’ll have to use the water we can extract locally.

Fortunately, water is a common molecule in the universe. Even the moon has plenty of water to sustain a lunar colony. The only real challenge is how to extract it. As a recent study published in Acta Astronautica shows, that might be as easy as popping things into a microwave oven.

Although wate...

An international team of space scientists has found that observation of a gas cloud stream heading into a massive galaxy may offer evidence of gas material recycling. In their paper published in the journal Science, the group describes their observance and analysis of a gas cloud surrounding a dense galaxy cluster 11 billion light years away, and what they learned from their work.

Space scientists have, for many years, predicted that enriched gases surrounding galaxies could be pulled into such galaxies and wind up as material for making new stars...

A “beautiful effect” predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized Xrays emitted by a magnetar – a neutron star featuring a powerful magnetic field, according to a Cornell astrophysicist.

The extremely dense and hot remnant of a massive star, boasting a magnetic field 100 trillion times str...
