New findings about ions around comets

Sofia Bergman, Swedish Institute of Space Physics (IRF) and Umeå University, will defend her doctoral thesis on low-energy ions around comet 67P/Churyumov-Gerasimenko on 26 November. Observing low energy ions is notoriously ...

The magnetic fields swirling within the Whirlpool galaxy

Messier objects are some of the most imaged objects in the universe. In part that's because many of them are so visibly appealing. A good example of that is the Whirlpool galaxy, M51, which recently received an even more ...

Galaxy survives black hole's feast—for now

Black holes are thought to gobble up so much surrounding material that they put an end to the life of their host galaxy. In that process they create a highly energetic object called a quasar which was previously thought to ...

Stellar pulsations distribute key ingredient for life

As Carl Sagan famously said, "We're made of star stuff"—but how do stars distribute their essential "stuff" for life into space? NASA's telescope on an airplane, SOFIA, is finding some answers by watching pulsating stars ...

Magnetic fields force new perspective on Milky Way's black hole

Observations from Stratospheric Observatory for Infrared Astronomy (SOFIA) indicate that the magnetic field near our galaxy's core is strong enough to control the material moving around the black hole, even in the presence ...

SOFIA finds clues hidden in Pluto's haze

When the New Horizons spacecraft passed by Pluto in 2015, one of the many fascinating features its images revealed was that this small, frigid world in the distant solar system has a hazy atmosphere. Now, new data helps explain ...

Flying observatory maps the Milky Way

A new panoramic image based on data captured by NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) shows the bustling center of our galaxy like it has never been seen before.

Magnetic field may be keeping Milky Way's black hole quiet

Supermassive black holes exist at the center of most galaxies, and our Milky Way is no exception. But many other galaxies have highly active black holes, meaning a lot of material is falling into them, emitting high-energy ...
