StarDate Online 5 Jun 2018, 05:00 UTC A star system in the constellation Ophiuchus, which is in the east on June evenings, can’t keep quiet. It pops off every decade or two. In just a day, it grows tens of thousands of times brighter. But those outbursts may be only the prelude to a bigger one: The star may blast itself to bits as a supernova.
ESOcast 4 Jun 2018, 15:00 UTC Astronomers using ALMA and the VLT have discovered that starburst galaxies in both the early and the nearby Universe contain a much higher proportion of massive stars than is found in more peaceful galaxies.
ESOcast 30 May 2018, 10:00 UTC Glowing brightly about 160 000 light-years away, the Tarantula Nebula is the most spectacular feature of the Large Magellanic Cloud, a satellite galaxy to our Milky Way. The VLT Survey Telescope at ESO’s Paranal Observatory in Chile has imaged this region and its rich surroundings in exquisite detail. It reveals a cosmic landscape of star clusters, glowing gas clouds and the scattered remains of supernova explosions. This is the sharpest image ever of this entire field.

41: Water vapour plumes on Europa - SpaceTime with Stuart Gary Series 21 Episode 41 - The Astronomy Podcast25 May 2018, 11:04 UTC What appears to be plumes of water vapor have been discovered erupting into space from below the frozen surface of Jupiter’s ice-moon Europa. And a new study claims the Sun will form a visible planetary nebula when it eventually dies. The findings may help resolve debate among astronomers about the ultimate fate of the Sun.
SpaceTime with Stuart Gary 23 May 2018, 11:26 UTC New evidence indicates the first stars formed just 250 million years after the big bang. Astronomers have discovered evidence that the universe’s first stars formed just 250 million years after the big bang.
NASACast Audio 18 May 2018, 21:19 UTC A conversation with Jon Jenkins, the science lead for the Science Processing Operations Center at NASA's Ames Research Center in Silicon Valley. At the SPOC, the raw data from NASA’s newly launched planet hunter, TESS, is prepared for scientists to analyze.
SpaceTime with Stuart Gary 18 May 2018, 08:38 UTC A new phase in a project to search the heavens for signs of Extra-Terrestrial intelligence has just commenced at the CSIRO’s Parkes Radio Telescope. It will be another six months before the Federal government decides on a location for Australia’s new Space Agency.
ESOcast 16 May 2018, 17:00 UTC Astronomers have used observations from the Atacama Large Millimeter/submillimeter Array (ALMA) and ESO’s Very Large Telescope (VLT) to determine that star formation in the very distant galaxy MACS1149-JD1 started at an unexpectedly early stage, only 250 million years after the Big Bang. This discovery also represents the most distant oxygen ever detected in the Universe and the most distant galaxy ever observed by ALMA or the VLT.
SpaceTime with Stuart Gary 16 May 2018, 12:10 UTC Astronomers have found that like some people galaxies grow bigger and puffier as they age. NASA has announced plans to send a helicopter to Mars in 2020. The small, autonomous rotorcraft drone will travel with the agency's Mars 2020 rover mission slated to launch in July 2020.
