NASA's IXPE helps researchers maximize 'microquasar' findings

The powerful gravity fields of black holes can devour whole planets' worth of matter—often so violently that they expel streams of particles traveling near the speed of light in formations known as jets. Scientists understand ...

Astronomers inspect supernova remnants with MeerKAT

Using the MeerKAT radio telescope, astronomers from the National Radio Astronomy Observatory (NRAO) in Charlottesville, Virginia, and elsewhere have investigated a batch of 36 high latitude supernova remnants. Results of ...

FAST telescope reveals unprecedented details of the Milky Way

The Milky Way is our home galaxy in the vast universe, but the structure and composition of the Milky Way remain mysterious. The vast interstellar space between the billions of stars is not empty, but filled with tenuous ...

Engineers solve data glitch on NASA's Voyager 1

Engineers have repaired an issue affecting data from NASA's Voyager 1 spacecraft. Earlier this year, the probe's attitude articulation and control system (AACS), which keeps Voyager 1's antenna pointed at Earth, began sending ...

Coherent interstellar magnetic field detected

Magnetic fields are the essential, but often "secret" ingredients of the interstellar medium and the process of making stars. The secrecy shrouding interstellar magnetic fields can be attributed to the lack of experimental ...

Science fiction revisited: Ramjet propulsion

In science fiction stories about contact with extraterrestrial civilisations, there is a problem: What kind of propulsion system could make it possible to bridge the enormous distances between the stars? It cannot be done ...

Cosmic rays may be key to understanding galactic dynamics

Cosmic rays are charged subnuclear particles that move close to the speed of light, constantly raining down on the Earth. These particles are relativistic, as defined by Albert Einstein's special relativity, and manage to ...
