A mysterious Fast Radio Burst (FRB) from beyond the galaxy has been detected at Arecibo. This is the first FRB discovered outside of Parkes Observatory, giving greater credence to the astronomical nature of these signals.
We can measure the expansion of the universe with velocities and distances of extragalactic objects. But measuring distances is tough! The authors of this paper have developed a new technique for measure the distances of AGN using the “echo” of light from heated dust.
A recent result on the commonality of exoplanets has made headlines, but has it for the right reasons?
By looking at the spectral changes of the accretion disk emission around black holes, we can trace the physical changes of the accreting material.
Astronomers are hearing a new type of radio transient, but no one knows where they come from and how they are created. This paper suggests one of the six documented Fast Radio Bursts detected so far originated close to home, within our own galaxy.
Tune in now for the first extrasolar weather map of a nearby brown dwarf, made using Doppler imaging.
Most binary stars probably formed at the same time, meaning all stars in the same system should have the same age. The authors of this paper analyze a stellar binary system where one star appears to be lying about its age, as one star appears 3 billion years older than its companion.
Small and massive compact galaxies are some of the hardest galaxies to find, but they could potentially reveal how galaxies evolved in the early universe.
By examining their expansion rate over time, Type II supernovae provide a way to measure extragalactic distances.
A new debris disk is discovered by the Herschel Space Telescope around the red dwarf tertiary star in the famous Fomalhaut system.
