56: Cosmic ray neutrinos traced back to their source for the first time - SpaceTime with Stuart Gary Series 21 Episode 5618 Jul 2018, 11:32 UTC Cosmic ray neutrinos traced back to their source for the first time: A new study has identified a distant supermassive black hole called a blazar as the source of mysterious high energy cosmic ray neutrinos bombarding the Earth.
SpaceTime with Stuart Gary 12 Jul 2018, 12:17 UTC Cataclysmic collision helped shape Uranus: A new study claims Uranus was hit by a massive object roughly twice the size of Earth causing the planet to roll over onto its side. Listening in on an interstellar visitor to confirm it’s not an alien spacecraft: When the interstellar visitor Oumuamua was observed failing to slow down as much as it should be due to the Sun’s gravitational pull -- scientists explored several scenarios to try to explain what was happening.
ESOcast 11 Jul 2018, 10:00 UTC New observations with ESO’s Very Large Telescope have revealed the star cluster RCW 38 in all its glory. These observations was taken during testing of the HAWK-I camera with the GRAAL adaptive optics system. It shows the cluster and its surrounding clouds of brightly glowing gas in exquisite detail, with dark tendrils of dust threading through the bright core of this young gathering of stars.

SpaceTime with Stuart Gary 6 Jul 2018, 12:01 UTC Interstellar asteroid may actually be a comet: A new study suggests Oumuamua (oh-MOO-ah-MOO-ah) -- the first interstellar object discovered in the solar system – may be an interstellar comet rather than an asteroid. Japan’s Hayabusa-2 reaches the unexplored asteroid Ryugu: After a journey lasting three and half years, Japan’s Hayabusa-2 spacecraft has finally reached its target -- the kilometre-wide near-Earth asteroid 162173 Ryugu.
StarDate Online 3 Jul 2018, 05:00 UTC The Sun is larger and brighter than most other stars in the galaxy. In fact, only a few percent of the Milky Way’s stars are about the same size, temperature, and brightness as the Sun. And at this time of year, if you have a dark sky and a good star chart, you can see two of them for yourself.
NASA's Jet Propulsion Laboratory Video and Audio Podcasts 2 Jul 2018, 07:00 UTC What's Up for July? Mars is closest to Earth since 2003! If you've been skywatching for 15 years or more, then you'll remember August 2003, when Mars approached closer to Earth than it had for thousands of years. It was a very small percentage closer, but not so much that it was as Mars was an awesome sight: in binoculars, where some large features could be seen, and especially through telescopes. Astronomy clubs everywhere had long lines of people looking through their telescopes at the red planet, and they will again this month!
