New results from HST show relativistic jets on scales rarely seen before
... speeds (6−7c) have been observed in the optical kpc-scale jet, our first proper-motion study of a powerful quasar jet reveals no significant proper motions.” Superluminal refers to the apparently faster-than-light motion seen in some...

Have astronomers found the missing mass in the Universe?
... low temperature (around 105 − 107K) and is of low density, previous attempts to observe it via X-ray emission or absorption in quasar spectra have proven difficult. Now, by looking at these warm-hot baryons through a phenomena known as the thermal...

Merger with the LMC spells doom for our Solar System
... our galaxy's dormant black hole thus turning the Milky Way into an 'active galactic nucleus' (AGN) or quasar. "This phenomenon will generate powerful jets of high energy radiation emanating from just outside the black...

Clashing galaxies may have triggered Solar System formation says new study
... measurements of Gaia, a mission that is also helping scientists to detect new asteroids, exoplanets, extragalactic sources such as quasars and has even provided some tests of Einstein’s theory of general relativity. “This is really the first time...
