That's interesting how each section of the sun rotates at different rates, and creates all the twisting magnetic fields. Never considered that before.

here's some more on that asteroid that came uncomfortably close, at least on a solar systems scale:

http://www.sciencealert.com/the-aste...-double-mooner

The damn rock had it's own moons!

"While many known asteroids have passed by closer to Earth than Florence ... all of those were estimated to be smaller," said JPL-NASA's Paul Chodas, manager of the Center for Near-Earth Object Studies.

"Florence is the largest asteroid to pass by our planet this close since the NASA program to detect and track near-Earth asteroids began."

So how big is big enough to have moons? Florence is just 4.4 kilometres (2.7 miles) across. The moons themselves truly are tiny, between 100-300 metres (300-1,000 feet) across, with orbits of around eight hours for the inner moon and between 22 and 27 hours for the outer moon.

It's actually not unusual for asteroids to have moons. Around 60 near-Earth asteroids of the roughly 16,400 known have at least one moon.



Now let's get that space based earth defense system in place ASAP. An asteroid strike is the one proven existent threat facing us that HAS happened before.

The remarkable Cassini probe is about to end it's long & illustrious career plunging to it's death in the atmosphere of Saturn.

https://www.nytimes.com/2017/09/08/s...smtyp=cur&_r=0

This amazing machine has been studying Saturn and its moons for over 13 years. Check out the article at the NYT as it has some spectacular pictures of Saturn and its moons. Rest in peace Cassini for a job well done.

Be VERY careful guys, I've seen these movies and it never ends well for us!

http://news.sky.com/story/shape-shif...ation-11033655

Bacterial cells treated with a common antibiotic have been spotted changing shape to survive while aboard the International Space Station (ISS).


Seriously this is fascinating and important work:

The study also found that the bacterial cell envelope - the cell wall and outer membrane - thickened in space, protecting the E coli from the antibiotic.

In space the bacteria also tended to form in clumps, which Dr Zea thought was perhaps a defensive manoeuvre, which could involve outer cells protecting the inner cells from antibiotics.

Some of the bacterial cells were also spotted producing membrane vesicles, small capsules that form outside of the cell walls and act as messengers for cells to communicate with each other.

When these cells reach a critical mass they can synchronise to begin the infection process.

"Both the increase in cell envelope thickness and in the outer membrane vesicles may be indicative of drug resistance mechanisms being activated in the space flight samples," said Dr Zea.

"This experiment and others like it give us the opportunity to better understand how bacteria become resistant to antibiotics here on Earth."

Okay, I'm going to get on my soap box about a topic that is dear to my heart: Why are we allowing irresponsible "scientists" to announce our location to the Galaxy?

https://www.cnet.com/news/next-year-...ch-for-aliens/

But many SETI astronomers aren't content with only scanning the airwaves for signs of ET. Instead, they think we should also be actively reaching out to the cosmos on behalf of planet Earth.

These astronomers occupy a controversial niche within the SETI community known as Messaging Extraterrestrial Intelligences, or METI. At the forefront of this group is Douglas Vakoch, president of METI International, a research group dedicated to designing and sending messages intended for extraterrestrial recipients.



This is a bad idea and thankfully more folks are seeing that:

Vakoch and his colleagues at METI International are fighting an uphill battle. Aside from all the technical problems that come with trying to contact aliens, many SETI astronomers think it's a bad idea.

The METI opposition group, which includes scientists like Stephen Hawking, argues that since we have no idea what ET might be like, sending a message into the cosmos comes with a huge existential risk. If the aliens happen to be friendly, no problem. But if they're hostile, that means we're essentially sending out a beacon that says "ATTACK HERE."



Hawking is absolutely right here. We simply don't understand the type of civilization it would take to cross that stars. But we can guess and the answer is disturbing. It is probable that the first requirement for a star faring civilization is that it arises from a predatory species. Natural selection gifts Predator's with a highly developed 3D thinking capability. This evolutionary imperative means that predators are more apt to develop higher order mathematics & physics. Necessary prerequisites to building a star spanning civilization.

It also doesn't hep that periods of war (WW 1 & 2) or simmering strife (Cold War) are the conditions that breed the greatest technological leaps. Bottom line is that it's reasonable to assume that a civilization that could cross the stars would be war like or at least domineering in a way that we would not want to deal with.

IMO it's a moral matter that we don't burden future generations with having to deal with the nightmare scenario of alien invasion. It doesn't matter if our reaching out to extraterrestrial civilizations doesn't end in disaster for us today. What gives us the right to set events in motion that will end in disaster for our heirs whether it's 100, 500 or even a 1,000 years in the future. I would support making it a crime to try to proactively contact extraterrestrials and would hope that governments act to prevent it.

^^^ I agree, lotr.

If the aliens are the alpha species of the galaxy and a million years more advanced, I liken it to humans discovering a new species of insects. We might study the new insect-species, but we wouldn't be considered "friendly" to them, nor would we try to understand their language and communicate with them or teach them new technologies. Why would we expect advanced aliens to treat us different?

Again, it's not wise to shout in a jungle.

I'm convinced BlackHawk that it's the people who believe that alien civilizations exist that are the ones demanding that we NOT try to contact them. As you say, "don't shout in the Jungle". On the other hand those wanting to reach out and shake their hands are either very naive or don't really believe they're out there.

Meanwhile here's an update about an amazing deep space mission currently underway:

http://www.astronomy.com/news/2017/0...is-awake-again

NASA’s New Horizons spacecraft is awake — temporarily — for a short burst of activity while on its way to its post-Pluto target in the Kuiper Belt, an object known as 2014 MU69. The spacecraft was put into hibernation mode April 7 to save power on its long journey, which is not yet complete. Now that it’s awake, the mission team will begin performing instrument checks and data collection for the next three months, as well as an additional flight path correction, before the spacecraft is returned to hibernation until it’s ready to encounter MU69 in 2019.


MU69 is a very interesting object at the edge of our solar system.

MU69 orbits the Sun over four billion miles (6.5 billion kilometers) from Earth, and it’s an additional one-billion-mile (1.5 billion km) jaunt past the Pluto system. Although New Horizons is heading for the Kuiper Belt object now, the mission ops team will complete one further course correction December 9, which will lock in the final date and time of New Horizons’ encounter with the mysterious world (or worlds — a recent occultation revealed that MU69 may be two bodies orbiting each other closely).


I still can't get my head around the fact that we are communicating with a probe that is exploring beyond Pluto - amazing stuff.

They are calling this the "Goth Planet" and for very good reasons:

http://nypost.com/2017/09/15/astrono...-black-planet/

The researcher team, which was led by researchers from McGill University in Canada and the University of Exeter in the UK, used the Hubble Space Telescope to catch a glimpse of WASP-12b in the hopes of learning more about it. What they soon realized was that the planet is so impossibly dark that it almost completely blends into the darkness of space.

Using the Hubble’s built-in spectrograph, the scientists were able to measure the amount of light the planet reflects, called albedo and found it to be an incredibly low. “The measured albedo of WASP-12b is 0.064 at most. This is an extremely low value, making the planet darker than fresh asphalt! The low albedo shows we still have a lot to learn about WASP-12b and other similar exoplanets.”

Now the task of determining exactly why the planet is so dark begins. Researchers have theorized that the planet’s close proximity to its star could be responsible. WASP-12b is twice the size of Jupiter and is so close to its star that it completes a full rotation in about one Earth day. That short distance means that the planet’s surface could top 2,600 degrees Celsius, which may mean its atmosphere is actually responsible for absorbing so much of the light that hits the planet.

An interesting article on some of the analytical tests that will be used to identify any fossilized bacteria that may be found on Mars. Such a discovery will change the way we look at the universe:

https://phys.org/news/2017-09-life-m...-vanadium.html

The search for biology on neighbor planet Mars won't play out like a Hollywood movie starring little green men. Rather, many scientists agree if there was life on the Red Planet, it probably will present itself as fossilized bacteria. To find it, astrobiologists likely will need to decode the chemical analysis of rock samples performed by a rover (like the one NASA plans to send to Mars in 2020). Only then might humankind know conclusively that life exists beyond Earth.

A new paper in the journal Astrobiology suggests NASA and others hunting for proof of Martian biology in the form of "microfossils" could use the element vanadium in combination with Raman spectroscopy on organic material as biosignatures to confirm traces of extraterrestrial life.
