Neutron Stars Are Weird!

There, we came right out and said it. They can’t help it; it’s just what happens when you have a star that’s heavier than our sun but as small as a city. Neutron stars give us access to crazy conditions that we can’t study directly on Earth.

Here are five facts about neutron stars that show sometimes they are stranger than science fiction!

1. Neutron stars start their lives with a bang

When a star bigger and more massive than our sun runs out of fuel at the end of its life, its core collapses while the outer layers are blown off in a supernova explosion. What is left behind depends on the mass of the original star. If it’s roughly 7 to 19 times the mass of our sun, we are left with a neutron star. If it started with more than 20 times the mass of our sun, it becomes a black hole.

2. Neutron stars contain the densest material that we can directly observe

While neutron stars’ dark cousins, black holes, might get all the attention, neutron stars are actually the densest material that we can directly observe. Black holes are hidden by their event horizon, so we can’t see what’s going on inside. However, neutron stars don’t have such shielding. To get an idea of how dense they are, one sugar cube of neutron star material would weigh about 1 trillion kilograms (or 1 billion tons) on Earth—about as much as a mountain. That is what happens when you cram a star with up to twice the mass of our sun into a sphere the diameter of a city.

3. Neutron stars can spin as fast as blender blades

Some neutron stars, called pulsars, emit streams of light that we see as flashes because the beams of light sweep in and out of our vision as the star rotates. The fastest known pulsar, named PSR J1748-2446ad, spins 43,000 times every minute. That’s twice as fast as the typical household blender! Over weeks, months or longer, pulsars pulse with more accuracy than an atomic clock, which excites astronomers about the possible applications of measuring the timing of these pulses.

4. Neutron stars are the strongest known magnets

Like many objects in space, including Earth, neutron stars have a magnetic field. While all known neutron stars have magnetic fields billions and trillions of times stronger than Earth’s, a type of neutron star known as a magnetar can have a magnetic field another thousand times stronger. These intense magnetic forces can cause starquakes on the surface of a magnetar, rupturing the star’s crust and producing brilliant flashes of gamma rays so powerful that they have been known to travel thousands of light-years across our Milky Way galaxy, causing measurable changes to Earth’s upper atmosphere.

5. Neutron stars’ pulses were originally thought to be possible alien signals

Beep. Beep. Beep. The discovery of pulsars began with a mystery in 1967 when astronomers picked up very regular radio flashes but couldn’t figure out what was causing them. The early researchers toyed briefly with the idea that it could be a signal from an alien civilization, an explanation that was discarded but lingered in their nickname for the original object—LGM-1, a nod to the “little green men” (it was later renamed PSR B1919+21). Of course, now scientists understand that pulsars are spinning neutron stars sending out light across a broad range of wavelengths that we detect as very regular pulses – but the first detections threw observers for a loop.

The Neutron star Interior Composition Explorer (NICER) payload that is soon heading to the International Space Station will give astronomers more insight into neutron stars—helping us determine what is under the surface. Also, onboard NICER, the Station Explorer for X-ray Timing and Navigation Technology (SEXTANT) experiment will test the use of pulsars as navigation beacons in space.

Ocean Worlds Beyond Earth

We’re incredibly lucky to live on a planet drenched in water, nestled in a perfect distance from our sun and wrapped with magnetic fields keeping our atmosphere intact against harsh radiation and space weather.

We know from recent research that life can persist in the cruelest of environments here on Earth, which gives us hope to finding life thriving on other worlds. While we have yet to find life outside of Earth, we are optimistic about the possibilities, especially on other ocean worlds right here in our solar system.  

So…What’s the News?!

Two of our veteran missions are providing tantalizing new details about icy, ocean-bearing moons of Jupiter and Saturn, further enhancing the scientific interest of these and other “ocean worlds” in our solar system and beyond!

Cassini scientists announce that a form of energy for life appears to exist in Saturn’s moon Enceladus, and Hubble researchers report additional evidence of plumes erupting from Jupiter’s moon Europa.

The Two Missions: Cassini and Hubble

Cassini

Our Cassini spacecraft has found that hydrothermal vents in the ocean of Saturn’s icy moon Enceladus are producing hydrogen gas, which could potentially provide a chemical energy source for life.

Cassini discovered that this little moon of Saturn was active in 2005. The discovery that Enceladus has jets of gas and icy particles coming out of its south polar region surprised the world. Later we determined that plumes of material are coming from a global ocean under the icy crust, through large cracks known as “tiger stripes.” 

We have more evidence now – this time sampled straight from the plume itself – of hydrothermal activity, and we now know the water is chemically interacting with the rock beneath the ocean and producing the kind of chemistry that could be used by microbes IF they happened to be there.

This is the culmination of 12 years of investigations by Cassini and a capstone finding for the mission. We now know Enceladus has nearly all the ingredients needed for life as we know it.

The Cassini spacecraft made its deepest dive through the plume on Oct. 28, 2015. From previous flybys, Cassini determined that nearly 98% of the gas in the plume is water and the rest is a mixture of other molecules, including carbon dioxide, methane and ammonia. 

Cassini’s other instruments provided evidence of hydrothermal activity in the ocean. What we really wanted to know was…Is there hydrogen being produced that microbes could use to make energy? And that’s exactly what we found!

To be clear…we haven’t discovered microbes at Enceladus, but vents of this type at Earth host these kinds of life. We’re cautiously excited at the prospect that there might be something like this at Enceladus too!

Hubble

The Hubble Space Telescope has also been studying another ocean world in our solar system: Europa!

Europa is one of the four major moons of Jupiter, about the size of our own moon but very different in appearance. It’s a cold, icy world with a relatively smooth, bright surface crisscrossed with dark cracks and patches of reddish material.

What makes Europa interesting is that it’s believed to have a global ocean, underneath a thick crust of ice. In fact, it’s got about twice as much ocean as planet Earth!

In 2014, we detected evidence of intermittent water plumes on the surface of Europa, which is interesting because they may provide us with easier access to subsurface liquid water without having to drill through miles of ice.

And now, in 2016, we’ve found one particular plume candidate that appears to be at the same location that it was seen in 2014. 

This is exciting because if we can establish that a particular feature does repeat, then it is much more likely to be real and we can attempt to study and understand the processes that cause it to turn on or off. 

This plume also happens to coincide with an area where Europa is unusually warm as compared to the surrounding terrain. The plume candidates are about 30 to 60 miles (50 to 100 kilometers) in height and are well-positioned for observation, being in a relatively equatorial and well-determined location.

What Does All This Mean and What’s Next?

Hubble and Cassini are inherently different missions, but their complementary scientific discoveries, along with the synergy between our current and planned missions, will help us in finding out whether we are alone in the universe. 

Hubble will continue to observe Europa. If you’re wondering how we might be able to get more information on the Europa plume, the upcoming Europa Clipper mission will be carrying a suite of 9 instruments to investigate whether the mysterious icy moon could harbor conditions favorable for life. Europa Clipper is slated to launch in the 2020s.

This future mission will be able to study the surface of Europa in great detail and assess the habitability of this moon. Whether there’s life there or not is a question for this future mission to discover!

THE REAL STORY BEHIND THE NAMJOON, WALE, AND VENNY INCIDENT

So long story short an “army” that goes by the name of Venny is pretty good at making celebrities notice bangtan. She got a retweet from wale from an old cover from namjoon and even got tinashe to notice hobi. 

But heres why you SHOULD NOT treat here as the best namjoon stan ever because she is not

*i dont want to bring up the past but a lot of people are comparing her with namjoon because VENNY IS PROBLEMATIC SHE MADE A LOT OF RACIST REMARKS AND NEVER APOLOGIZED OR OWNED UP TO THEM AND EVEN REPEATED THEM UNLIKE NAMJOON*

So basically many armys AND HER claim that the collab happened because of her WHICH I HIGHLY DOUBT BECAUSE ME KNOWING NAMJOON HE WOULD OF SAID SOMETHING HIMSELF

so then venny venn diagram releases these on her twitter (WHICH IS NOW PRIVATE COINCIDENCE I THINK NOT)

Okay but e ven before i knew that this was fake I HIGHLY DOUBTED IT namjoon would of done something himself he has the full capability to dm and message intl armys he has done so before

also she sounded soooooo shady i wasnt buying it

BUT THEN

so then seeing this beef wale assumed namjoon knows venny venn diagram not knowing the real situation

BUT NAMJOON DOESNT KNOW WHO TF THIS PROBLEMATIC SHIT IS
THIS COLLAB DIDNT HAPPEN BECAUSE OF YOU BOO

the fact that some people dont know this AND ARE ACTING LIKE SHE IS THE BEST NAMJOON STAN IS DISGUSTING BECAUSE THERE ARE SO MANY BEAUTIFUL NAMSTANS OUT THERE NOT THIS LYING SHIT WHO WANTED TO BE NOTICED SO DAMN BAD

I feel really bad for her BECAUSE SHE IS SO PETTY
LIKE YOU ALREADY LIED AND EVERYONE KNOWS STOP TRYNA COVER YOURSELF UP
WE ARE ARMYS
WE ARE DETECTIVES WE WILL FIGURE OUT EVERYTHING

okay but basically i dont know what to do

the whole situation is so petty and stupid, like did this girl REALLY have to do this, being a namjoon stan since pre-debut i wouldnt be this thirsty to get namjoon to notice me, like i dont really know what to do because she already has done it and really cant take it back.

but hey im happy this happened because the twitter memes about her are so funny

peace, love, and support namjoon’s mixtape

*note* so many people are supporting namjoon remember when everyone used to fucking hate him people are giving him so much love i love armys we are amazing we need to protect namjoon 

i feel bad for namjoon bc this is affecting his career, some “armys” are no different from antis using namjoon as a fucking target for everything, i remember him mentioning that he wont feel as if his life has purpose until his music affect the lives of his fans and now when he actually gets to know an intl “army” its about something negative and false accusations against him. Imagine how hard breaking he would feel GREAT START TO HIS SECOND MIXTAPE UGH

LEAVE HIM ALONE

atfirst i thought it was stupid to hate on  venny as what she did was a harmless petty joke but this can really affect namjoon’s image in his rap career as wale knows about this

imagine how ashamed he felt goddamn

Mistakes were made. And worse is that you failed to keep the subjects contained and recover them after the initial breach. Now we have potentially dangerous individuals at large. Over 30 of them

And currently we only have budget to surveil one

  • Shirou: Saber, are you all right??
  • Saber: Yes, thank you, I'm fine.
  • Lemony Snicket from outta nowhere: Of course, in this case, 'fine' is only meant to reassure. She has never been less fine, nor was she ever fine in the first place. Here, the word 'fine' could be defined as 'I am actually slowly dying on the inside, but don't wish for anyone to worry.'

Brooklyn Nine-Nine to take on racial profiling with stop-and-frisk episode

Brooklyn Nine-Nine tends to take a light-hearted approach when it comes to the long arm of the law: After all, it’s a comedy in which Andy Samberg effuses lines like “Don’t worry, we can outsmart some small-town sheriff. We’re NYPD detectives. We caught the Son of Sam! Ice-T plays us on TV! We keep the Tonys safe!” But an upcoming episode is aiming to mine humor in a serious topic involving the police: Racial profiling via the controversial stop-and-frisk program, in which officers temporarily detain and search citizens for concealed weapons and illegal goods.

In an episode airing May 2 on Fox, Terry (Terry Crews) — a sergeant in the Nine-Nine — is subjected to a stop-and-frisk (which, coincidentally, is also known as a “Terry stop“) by an officer when he’s on the street looking for his daughter’s blankie. “He tries to work it out with the cop by going out to dinner with him, but that doesn’t work out, and he has to decide whether or not to file a formal complaint,” series co-creator Dan Goor tells EW. “To a certain extent, it’s the question of: Am I blue or am I black?”

It’s a subject matter that the show’s writers have been wanting to tackle for a long time, but “because our heroes are the police, it’s difficult to talk about the police in an abstract way,” says Goor. “We’ve talked about a million different stories and I think this one really works. It felt very natural and real, but at the same time, we’ve managed to make it as funny as any other Brooklyn Nine-Nine episode.”

The idea for the story stemmed from a conversation with Crews, who revealed a similar incident in which he had been racially profiled. The writers began working on an episode but were having trouble around the halfway mark. It was a conversation about the episode with a different cast member — Andre Braugher, a.k.a. Captain Holt — that led to a breakthrough moment. “Andre told me what he thought Captain Holt would do at that moment,” says Goor. “And it was like the clouds parted and I could see for the first time. It was so unexpected, but true to the character and honest, and made for an entire act’s worth of scenes.”

In the episode, after Terry hashes it out with other members of the Nine-Nine, “ultimately it comes down to a great set of scenes between Holt and [Terry],” says Goor. “It’s Andre at the height of Andre and Terry really keeps up with him. And it’s the first time we’ve done an A story for anyone other than Jake.”

Speaking of Jake (Samberg), he and Amy (Melissa Fumero) will spend most of the episode taking care of Terry’s twins with Sharon (Merrin Dungey) out of town. “They want to know why their dad was arrested, so Jake and Amy have to talk about these issues with these kids,” says Goor. “It’s one of the funniest stories we’ve done.”
