cool, but looks like we have to wait to 2029 to get contact with life forms there: Jupiter Icy Moons Explorer (JUICE) slated to reach the Jupiter system in 2029

79 moons last time we did birth control of Saturn. If these big planets keeps getting so many babies the solar system will get over moonlated.

Discovery of 20 new moons gives Saturn a solar system record

"the massive haul comes just over a year after astronomers announced 12 new moons orbiting Jupiter, but with the latest finds, Saturn’s retinue now surpasses Jupiter’s 79 known natural satellites."

reminds me off NASA Did the Moon Form in Natural Nuclear Explosion? (could even explain the Fermi paradox?)

A Fast Radio Burst 500 Million Light Years Away Is Repeating - Forbes Feb 11

Every 16.35 days

“One idea is that it is due to the orbital period of a binary system, such as a neutron star orbiting a young OB star. OB stars are massive and highly energetic. Neutron stars are dense and have strong magnetic fields. A close binary of the two could create a beam of high energy radio light.”

More from the original paper here:

The golden age of neutron star physics has arrived
Nature
March 4

https://www.nature.com/articles/d41586-020-00590-8

“ Last December, this NASA space observatory provided astronomers with some of the most precise measurements ever made of a neutron star’s mass and radius1,2, as well as unexpected findings about its magnetic field1,3. The NICER team plans to release results about more stars in the next few months. Other data are coming in from gravitational-wave observatories, which can watch neutron stars contort as they crash together. With these combined observations, researchers are poised to zero in on what fills the innards of a neutron star.”...

Not to lose sight of the really really big picture.

Hehe - indeed.  But then what?  Looks like dense matter.  Not to be confused with dark matter!
Anyway nice to read more about this mystery tonight. I'm going off planet for awhile. : )

Thanks. That's very interesting and I had no clue. Had never even heard of 'hyperons'.

Here something to do as an isolation-deprivation-constellation lurks in the corner of your living room. : )

Design a payload for a mini moon rover - one of NASA’s next missions!

https://www.herox.com/NASApayload/guidelines

“ The Commercial Lunar Payload Services (CLPS) program supports the Artemis Program through the development and deployment of small robotic landers and rovers. These new lunar micro-rovers will be launching over the next several years to gather information about and conduct scientific research on the lunar surface. To meet the size, weight, and power constraints of these micro-rovers, new scientific payloads have to be designed, built, and tested in time for the different launch opportunities.”...
...
“ The timeline for establishing a pipeline of suitable payloads is aggressive. NASA plans to launch the first of these micro-rovers in 2022. To be successful in this ideation competition, your proposed miniaturized payloads will:

- Bridge one or more of the highlighted lunar strategic knowledge gaps
- Have a technology readiness level (TRL) of 3 or greater
- Be compatible with the new micro-rovers

...

Key payload guidance includes:

- Ability to manage external temperatures ranging from -120° to +100°C
- Maximum exterior enclosed dimensions of 100mm x 100mm x 50mm
- Maximum mass of 0.4Kg

**
more details on the link and although you would surrender the IP, there is prize money totaling $160,000.

Plus you can brag about how you built something for NASA forever!

Coronavirus: What's the latest with Brexit and other big stories?

In the meantime, outside of our Covid bubble:
1. Brexit - no need to worry about the travel and business disruption in the transition period anymore
2. Wars in Syria and Yemen temporarily halt. Do we need to bailout the Western arms industry?
3. Sanders drops out from Prickness Stakes. Now Americans voters will choose between fingering and grabbing.
4. Australian tourism collapses after the great fires - even Covid doesn't want to come.

And 5 from me (as usual they ignored Africa):

Fine details, but those are terrestrial news items.

Back to Outer Space!

The brightest supernova ever seen - CNN April 13

"The light emitted in ordinary supernovae is usually less than 1% of the total energy. But this supernova, called SN2016aps, radiated more than five times the explosion energy of a typical supernova. After observing the explosion for two years, the scientists found the mass was between 50 to 100 times greater than the sun. The mass of a normal-sized supernova is between eight to 15 times greater. 
The researchers were searching the night sky trying to pick out the "most exotic and the most rare types of supernova explosions," Edo Berger, professor of astronomy at Harvard University and co-author of the study, said. 
"This is one of the best examples we've had," he added. "This is the type of event we estimate is something like one in 1,000 to one in 10,000 stars end their life in this way. So this is an extremely rare type of explosion and incredibly energetic. And this is exactly what we set out to find.""

Due to spectacular phenomena like this, the aforementioned  isolation-deprivation-constellation that inhabits my living room is just sulking by itself. : )
