AFM’s Space Pirate Radio 2017/10/19 Sometimes It’s Hard To Get Rid Of A Bomb!

October 19th, 2017 by Nick Evetts

Marty &  John tonight


Meanwhile, looking up at the night sky this week:
Wed, Oct 18, 00h Venus 2° S. of Moon
Thu, Oct 19, 18h Uranus at opposition
Thu, Oct 19, 19h NEW MOON
Tue, Oct 24, 12h Saturn 3° S. of Moon
Wed, Oct 25, 02h Moon at apogee
Times given in UT. These events, and more can be found at:  http://asa.usno.navy.mil/


Today, Oct. 18th, solar wind is blowing around Earth with less speed and pressure than previously expected. As a result, NOAA forecasters have lowered the odds of polar geomagnetic storms to only 30%.
Get ready, the sky’s going to be falling:





Japan’s lunar probe discovers moon cave, which may be optimal base for space exploration


Soyuz capsule suffered partial depressurization during April landing

Musk offers more technical details on BFR system

Focus On: Messier 80

October 9th, 2017 by Tavi Greiner


Messier 80, aka M80, is a globular cluster located nearly 33,000-light-years away, towards the constellation Scorpius. While most of the stars in this cluster are of similar age – about 13-billion years – scientists have noted a large number of younger “blue stragglers” within the cluster’s core. M80 also contains many bright red-giants, which you can see in greater detail by clicking on the Hubble image at left.


Globular clusters are dense collections of tens-of-thousands to hundreds-of-thousands of gravitationally-bound stars. They include the oldest stars in a galaxy and orbit the galactic core as a halo system. Our Milky Way has about 150 known globular clusters; larger galaxies can contain hundreds and even thousands of globular clusters. With upwards of 200,000 stars, our subject cluster, M80, is one of the most densely populated globulars in our galaxy. A few globulars, like M13 and Omega Centauri, contain even more stars.

Blue stragglers, like those found in M80, are younger main-sequence stars that are more massive and luminous than the general population of a cluster. The prevailing theory for their existence centers around the interactions between two or more cluster stars, resulting in the consequential transference of materials from one star to another.

Red-giants are older main-sequence stars with vastly inflated, thus cooler but brighter, atmospheres and lower masses. Our own Sun will someday expand into a red-giant star, engulfing the inner planets as it undergoes the hydrogen shell fusion stage.

The entire collection of M80’s stars spans some 96-light-years across. It has an apparent diameter of 10′, an apparent magnitude of 7.8, and appears as a distinctly fuzzy ball of light through a telescope or higher-powered binoculars. You can find this celestial gem about 4-degrees NW of bright red Antares (or between the scorpion’s bright red eye and its famous claw,) anytime that Scorpius is visible in your local sky. While you’re looking for M80, check-out another globular beauty, Messier 4, closer to Antares.

** ESO and HST offer some stunning images of globular (and open) clusters, here and here. **

AFM’s Space Pirates 2017/10/04 Dust In The Vacuum

Breaking – bolide over China:

2-4 meter superbolide just fell over southern China!
Wed Oct 4, 2017 12:16 pm (PDT) . Posted by: planetaryscience

Dear all,

Looks like the new CNEOS page has kept much more up to date- just 7 hours ago a bolide traveling 14.6 km/s fell over the northern parts of China’s Yunnan province, near the northern border of Myanmar!

They estimate a radiated energy around 192 gigajoules, the making it the most energetic “impact” in several months after the 2017/06/20 event, and the most energetic “impact” over land in over a year since the 2016/06/27 event over Mauritania!

It’s the middle of the night in China, so unsurprisingly I haven’t been able to find any photos or new sources on it, but expect the news to catch on in a few hours! This is the largest impact over china since the 2000/12/15 event, and will definitely merit attention in one way or another.

Hi Sam,

There is quite a buzz over the Chinese social media about this event. A video can be found here: http://weibo.com/tv/v/FoR0Lbl7Y?fid=1034:a827d14877a01e2e02f9b2c4bb9a2454

The event occurs at about 8 pm local time, and because it was a holiday in China (mid-autumn day of which there is a tradition of moon-gazing) there are a lot of witnesses. There are also reports about ground shaking after the flash.

Unfortunately the area is quite mountainous, so meteorite search would be difficult.
