Direct link 54: Cataclysmic collision helped shape Uranus - SpaceTime with Stuart Gary Series 21 Episode 54

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.

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.

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.

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.

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!

Direct link 51: Astronomers witness a star ripped apart by rare black hole - SpaceTime with Stuart Gary Series 21 Episode 51

1 Jul 2018, 09:43 UTC Astronomers witness a star ripped apart by rare black hole: Astronomers have detected a rare intermediate mass black hole as it ripped apart and devoured a passing star. Finding missing cosmic matter: Astronomers have solved another of the cosmos’s mysteries finding the last of the universe’s missing ordinary matter. The ongoing mystery of the big wow signal: The Wow! signal represented as 6EQUJ5 was a strong narrowband radio signal received on August 15, 1977, by Ohio State University's Big Ear radio telescope which at the time in the United States, then was being used by SETI -- the search for extra-terrestrial intelligence.

Direct link ESOcast 168: NEOs — Near Earth Objects

29 Jun 2018, 14:00 UTC Near Earth Objects (NEOs) are bodies in the Solar System with orbits that can bring them into close proximity with the Earth. Every day, many of these objects collide with our planet, but most are too small to have any noticeable effect. However, there are larger objects that lurk within our Solar System with the potential to impact the Earth, like the large Chelyabinsk meteor in 2013, or even larger -- like the devastating asteroid impact that wiped out the dinosaurs. With the fate of the world at stake, scientists and engineers are working hard to protect us from these collisions. In ESOcast 168 we hear from Olivier Hainaut, an ESO astronomer, who explains the origin and nature of NEOs. He will also explore the potential threat NEOs pose to life on Earth, how we study them with ESO telescopes like the VLT, and how scientists plan to shield the Earth from this extraterrestrial threat.

Direct link 50: Martian Dust Storm Grows Global - SpaceTime with Stuart Gary Series 21 Episode 50

29 Jun 2018, 08:06 UTC New data from an armada of spacecraft at Mars has confirmed that a massive dust storm on the red planet has gone global. Astronomers have captured a rare glitch in the usually regular clockwork like spin of a pulsar. Ever since Voyager 1 flew past Jupiter back in the 1970s scientists have wondered about the origin of Jupiter's lightning which seemed to be very different to lightning on Earth. Now new data from NASA’s Juno spacecraft has found that while Jovian lightning is in some ways analogous to Earth's lightning – the two types are two types are poles apart in other ways.
