Space Time with Stuart Gary Series 19 Ep.17 - Searching for gamma ray emissions from black holes
Hi...Stuart here with the Show Notes for Ep.17...here's what's on the show:
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.
April Skywatch We turn our eyes to the skies as Jonathan Nally -- the editor of Australian Sky and Telescope Magazine -- takes us on a journey through this month’s night skies with Skywatch.
