Searching for gamma ray emissions from black holes
Astronomers have failed to find any electromagnetic counterpart signal to the historic first ever direct detection of gravitational waves. The lack of an afterglow provides further support for the idea that the event was generated by a pair of black holes – 1.3 billion light years away -- as they spiralled in towards each other before merging.
Continuing the search for gravitational waves
While scientists were able to announce the confirmed detection of gravitational waves for the first time, the precise epicentre where those waves originated from is still a mystery. Pin pointing the exact location of a gravitational wave source will be of vital importance for studying the objects generating them.
Alien world blacker than coal
Astronomers have discovered distant gas giant similar to Jupiter -- but far more alien than any planet in our solar system. Instead of displaying Jupiter’s gleaming white and pink coloured clouds, this strange exoplanet is darker than the blackest lump of coal reflecting just one percent of the light reaching it.
Asteroid slams into Jupiter
Amateur astronomers in Austria and Ireland got the shot of a lifetime when they imaged what’s thought to be an asteroid slamming into Jupiter. At least two sky watchers were independently videoing the gas giant on March 17 when they both caught a massive ejecta blast erupting on the Jovian limb -- north of the planet’s equator.
