Active Galaxy

German astronomers have measured the magnetic field in the vicinity of a supermassive black hole. A bright and compact feature of only 2 light-days in size was directly observed by a world-wide ensemble of millimeter-wave radio telescopes in the heart of the active galaxy NGC 1052.

Sounding Rocket Solves a Cosmic Mystery, Reveals Another

In the last century, humans realized that space is filled with types of light we can't see - from infrared signals released by hot stars and galaxies, to the cosmic microwave background that comes from every corner of the universe. Some of this invisible light that fills space takes the form of X-rays, the source of which has been hotly contended over the past few decades.

Massive Holes Punched Through a Trail of Stars Likely Caused by Dark Matter

Massive Holes Punched Through a Trail of Stars Likely Caused by Dark Matter

Researchers have detected two massive holes which have been 'punched' through a stream of stars just outside the Milky Way, and found that they were likely caused by clumps of dark matter, the invisible substance which holds galaxies together and makes up a quarter of all matter and energy in the universe.
