Astronomers have used the ALMA and IRAM telescopes to make the first direct measurement of the temperature of the large dust grains in the outer parts of a planet-forming disc around a young star. By applying a novel technique to observations of an object nicknamed the Flying Saucer they find that the grains are much colder than expected: −266 degrees Celsius. This surprising result suggests that models of these discs may need to be revised.(learn more)

Birth of black hole kills the radio star

Source: Space Daily


Perth, Australia (SPX) Dec 27, 2013 - Astronomers led by a Curtin University researcher have discovered a new population of exploding stars that "switch off" their radio transmissions before collapsing into a Black Hole. These exploding stars use all of their energy to emit one last strong beam of highly energetic radiation - known as a gamma-ray burst - before they die.(learn more)

Radio Galaxy Zoo

Zooniverse has launched a new tool.

Earlier this year, Galaxy Zoo expanded to include the infrared. Now Radio Galaxy Zoo involves looking at galaxies in (yet) another light. This time we are asking you to match huge jets – seen in radio emission – to the supermassive black holes at the centre of the galaxy that produced them. This requires looking at the galaxies in infrared and radio wavelengths. These galaxies are not like our own, and your classifications will allow scientists to understand the causes of these erupting black holes and how they affect the galaxy surrounding them.


Get involved now at http://radio.galaxyzoo.org - and have fun discovering black holes in our Universe.
