33: The most sensitive ever Dark Matter search gets underway - SpaceTime with Stuart Gary Series 21 Episode 3327 Apr 2018, 07:56 UTC Scientists have begun their most sensitive ever search for a possible Dark Matter candidate called the Axion. Gamma rays are the most energetic forms of electromagnetic radiation and are emitted by some of the most powerful events in the universe. Now, a team of astronomers have published 14 papers in a special issue of the journal Astronomy & Astrophysics covering some fifteen years of gamma ray observations of the Milky Way.

32: NASA launches its latest planet-hunting spacecraft - SpaceTime with Stuart Gary Series 21 Episode 3225 Apr 2018, 11:55 UTC The Transiting Exoplanet Survey Satellite or TESS has blasted into orbit aboard a SpaceX Falcon 9 rocket from space launch complex 40 at the Cape Canaveral Air Force Base in Florida. TESS will follow on from NASA’s Kepler Space Telescope which helped scientists identify over two thousand six hundred exoplanetary candidates orbiting distant stars.
StarTalk Radio 20 Apr 2018, 22:00 UTC This week, Chuck Nice asks Neil deGrasse Tyson fan-submitted questions on a range of topics we couldn’t answer in other episodes. Now extended with a session of “Neil’d It” – where Neil and Chuck comb Internet comments to see if the science is right. (Adult Language).
SpaceTime with Stuart Gary 20 Apr 2018, 12:33 UTC Astronomers are back in the dark about what dark matter might be, after new observations have shown that it’s not interacting with forces other than gravity after all. The findings add more mystery to the enigma of dark matter – an invisible substance which makes up over 80 percent of all the matter in the universe.
Hubblecast HD 19 Apr 2018, 14:00 UTC On 24 April 1990, Hubble was launched into space. To celebrate its 28th year in orbit, some of Hubble’s precious observation time was used to observe the colourful Lagoon Nebula. One of only two star-forming nebulae visible to the unaided eye, this spectacular stellar nursery is not quite the tranquil landscape its name suggests. This new Hubblecast explores the image in more detail and shows some of the delicate features of this cosmic lagoon.
SpaceTime with Stuart Gary 18 Apr 2018, 11:52 UTC Astronomers peering deep into the violent heart of a supernova debris field have discovered a slowly expanding torus shaped cloud of oxygen and neon surrounding a young neutron star. The findings provide new insights into the processes involved in the explosive deaths of massive stars through core collapse supernovae.
