Solar System: 10 Things to Know This Week

The Living Planet Edition

Whether it’s crops, forests or phytoplankton blooms in the ocean, our scientists are tracking life on Earth. Just as satellites help researchers study the atmosphere, rainfall and other physical characteristics of the planet, the ever-improving view from above allows them to study Earth’s interconnected life.

1. Life on Earth, From Space

While we (NASA) began monitoring life on land in the 1970s with the Landsat satellites, this fall marks 20 years since we’ve continuously observed all the plant life at the surface of both the land and ocean. The above animation captures the entirety of two decades of observations.

2. Watching the World Breathe

With the right tools, we can see Earth breathe. With early weather satellite data in the 1970s and ‘80s, NASA Goddard scientist Compton Tucker was able to see plants’ greening and die-back from space. He developed a way of comparing satellite data in two wavelengths.

When healthy plants are stocked with chlorophyll and ready to photosynthesize to make food (and absorb carbon dioxide), leaves absorb red light but reflect infrared light back into space. By comparing the ratio of red to infrared light, Tucker and his colleagues could quantify vegetation covering the land.

Expanding the study to the rest of the globe, the scientists could track rainy and dry seasons in Africa, see the springtime blooms in North America, and wildfires scorching forests worldwide.

3. Like Breathing? Thank Earth’s Ocean

But land is only part of the story. The ocean is home to 95 percent of Earth’s living space, covering 70 percent of the planet and stretching miles deep. At the base of the ocean’s food web is phytoplankton - tiny plants that also undergo photosynthesis to turn nutrients and carbon dioxide into sugar and oxygen. Phytoplankton not only feed the rest of ocean life, they absorb carbon dioxide - and produce about half the oxygen we breathe.

In the Arctic Ocean, an explosion of phytoplankton indicates change. As seasonal sea ice melts, warming waters and more sunlight will trigger a sudden, massive phytoplankton bloom that feeds birds, sea lions and newly-hatched fish. But with warming atmospheric temperatures, that bloom is now happening several weeks earlier - before the animals are in place to take advantage of it.

4. Keeping an Eye on Crops

The “greenness” measurement that scientists use to measure forests and grasslands can also be used to monitor the health of agricultural fields. By the 1980s, food security analysts were approaching NASA to see how satellite images could help with the Famine Early Warning System to identify regions at risk - a partnership that continues today.

With rainfall estimates, vegetation measurements, as well as the recent addition of soil moisture information, our scientists can help organizations like USAID direct emergency help.

The view from space can also help improve agricultural practices. A winery in California, for example, uses individual pixels of Landsat data to determine when to irrigate and how much water to use.

5. Coming Soon to the International Space Station

A laser-based instrument being developed for the International Space Station will provide a unique 3-D view of Earth’s forests. The instrument, called GEDI, will be the first to systematically probe the depths of the forests from space.

Another ISS instrument in development, ECOSTRESS, will study how effectively plants use water. That knowledge provided on a global scale from space will tell us “which plants are going to live or die in a future world of greater droughts,” said Josh Fisher, a research scientist at NASA’s Jet Propulsion Laboratory and science lead for ECOSTRESS.

6. Seeing Life, From the Microscopic to Multicellular

Scientists have used our vantage from space to study changes in animal habitats, track disease outbreaks, monitor forests and even help discover a new species. Bacteria, plants, land animals, sea creatures and birds reveal a changing world.

Our Black Marble image provides a unique view of human activity. Looking at trends in our lights at night, scientists can study how cities develop over time, how lighting and activity changes during certain seasons and holidays, and even aid emergency responders during power outages caused by natural disasters.

7. Earth as Analog and Proving Ground

Just as our Mars rovers were tested in Earth’s deserts, the search for life on ocean moons in our solar system is being refined by experiments here. JPL research scientist Morgan Cable looks for life on the moons of Jupiter and Saturn. She cites satellite observations of Arctic and Antarctic ice fields that are informing the planning for a future mission to Europa, an icy moon of Jupiter.

The Earth observations help researchers find ways to date the origin of jumbled, chaotic ice. “When we visit Europa, we want to go to very young places, where material from that ocean is being expressed on the surface,” she explained. “Anywhere like that, the chances of finding biomarkers goes up - if they’re there.”

8. Only One Living Planet

Today, we know of only one living planet: our own. The knowledge and tools NASA developed to study life here are among our greatest assets as we begin the search for life beyond Earth.

There are two main questions: With so many places to look, how can we home in on the places most likely to harbor life? What are the unmistakable signs of life - even if it comes in a form we don’t fully understand? In this early phase of the search, “We have to go with the only kind of life we know,” said Tony del Genio, co-lead of a new NASA interdisciplinary initiative to search for life on other worlds.

So, the focus is on liquid water. Even bacteria around deep-sea vents that don’t need sunlight to live need water. That one necessity rules out many planets that are too close or too far from their stars for water to exist, or too far from us to tell. Our Galileo and Cassini missions revealed that some moons of Jupiter and Saturn are not the dead rocks astronomers had assumed, but appear to have some conditions needed for life beneath icy surfaces.

9. Looking for Life Beyond Our Solar System

In the exoplanet (planets outside our solar system that orbit another star) world, it’s possible to calculate the range of distances for any star where orbiting planets could have liquid water. This is called the star’s habitable zone. Astronomers have already located some habitable-zone planets, and research scientist Andrew Rushby of NASA Ames Research Center is researching ways to refine the search. “An alien would spot three planets in our solar system in the habitable zone [Earth, Mars and Venus],” Rushby said, “but we know that 67 percent of those planets are not inhabited.”

He recently developed a model of Earth’s carbon cycle and combined it with other tools to study which planets in habitable zones would be the best targets to look for life, considering probable tectonic activity and water cycles. He found that larger planets are more likely than smaller ones to have surface temperatures conducive to liquid water. Other exoplanet researchers are looking for rocky worlds, and biosignatures, the chemical signs of life.

10. You Can Learn a Lot from a Dot

When humans start collecting direct images of exoplanets, even the closest ones will appear as only a handful of pixels in the detector - something like the famous “blue dot” image of Earth from Saturn. What can we learn about life on these planets from a single dot?

Stephen Kane of the University of California, Riverside, has come up with a way to answer that question by using our EPIC camera on NOAA’s DSCOVR satellite. “I’m taking these glorious pictures and collapsing them down to a single pixel or handful of pixels,” Kane explained. He runs the light through a noise filter that attempts to simulate the interference expected from an exoplanet mission. By observing how the brightness of Earth changes when mostly land is in view compared with mostly water, Kane reverse-engineers Earth’s rotation rate - something that has yet to be measured directly for exoplanets.

The most universal, most profound question about any unknown world is whether it harbors life. The quest to find life beyond Earth is just beginning, but it will be informed by the study of our own living planet.

A mermaid’s purse or devil’s purse is a casing that surrounds the fertilized eggs of some sharks, skates, and chimaeras. They are among the common objects which are washed up by the sea. They are made of collagen protein strands.

Because they are lightweight, they are often found at the strandline, the farthest point of the high tide. The egg cases that wash up on beaches are usually empty, the young fish having already hatched out.

So I logged onto Tumblr

And In the bottom left corner of my screen I see a horse icon

And of course I’m naturally like “what the hell is on my dash.” Curious, I clicked it and hoped to the overlords that it wasn’t a virus (specifically a trojan) and I see this

And my level of “wtf” went up a notch. Why do I just suddenly have a horse on my dash that I have to take care of Tumblr don’t hand me responsibility like this. While I was taking the screenshot and saving it I looked back it. 

And it died?!?!? How????? I just got it and it’s already dead

@staff What is this and why do you demand such responsibility from me?

Organisms change/ Nolan Holloway

Request: 23, 52, and 76 with Nolan please? I love his character so much :) <3 @bekindtomehistory

Prompt(s): 23. “I think I’m in love with you and you don’t get how much that            fucking scares me”

52. “When was the last time you slept?”

 76. “Why should I apologize for the monster I’ve become when no       ones apologized for making me this way.”                                                  


You had been friends with Nolan for a long time and yeah okay he had some problems but who doesn’t. You of course had a huge crush on him I mean have you seen him. You didn’t tell him because you didn’t wanna ruin your friendship but he had the biggest crush on you too. Lately Nolan had been really scared because of all of the supernatural stuff happening. You knew of the supernatural world because well you’re brother was Corey so you are in Scott’s pack. You had tried to tell Nolan to just stop freaking out about it and that nothing weird was going on but for some reason he just couldn’t stop thinking about it. You were waiting outside of school on Nolan to arrive. When he arrived you smiled but that smile fell really fast when you saw how bad he looked.

“Oh my god Nolan you look like shit.” You said looking at him.

“Wow thanks Y/N.” He said as he rubbed his eyes as the two of you walked into school.

When was the last time you slept?” You asked concerned.

“I-I don’t know.” He said as he opened his locker when the two of you arrived there.

“Well that isn’t good.” You said crossing your arms.

“You really need to stop freaking out about this stuff Nolan. Everything is normal okay.” You said trying to calm him.

“N-no it’s not Y/N. Nothing is normal. You’re brother isn’t normal. A-and I’m gonna prove it to you.” He said closing his locker and walking away from you.

You just sighed and turned around and tried to look for your brother. You saw him standing at his locker with Mason and Liam.

“Corey just a heads up. Nolan is going to try to show me that you aren’t normal.” You said with a sigh.

“Oh so now they want to expose me too.” He said rolling his eyes.

“Yeah sorry bro.” You said looking at him with a small smile.

“It’s fine it’s not your fault.” He said smiling at you.

The rest of the day every time you saw Nolan he just looked towards you very nervously and then just walked or looked away. Later that day you were in the library with Mason and your brother You were studying for the Biology test while Corey and Mason were talking about something. Suddenly you heard a book slam onto the table and you looked up.

“Hey Nolan.” Corey said looking at Nolan nervous because he knew he wanted to expose him.

“Studying for the Bio test?” Mason asked looking at him while Nolan just kept looking at the three of us.

“T-trying yeah……Um trying to understand how organisms often change…….Like how a fish can turn into an alligator.” He said while he went to sit down and just kept looking at the three of us but mostly at Corey.

“Alligator’s aren’t fish, there reptiles they hatch from fertilized eggs…..” Mason started to explain until Corey cut him of.

“And isn’t the test on DNA versus RNA.” Corey said looking at Nolan

You looked at Nolan and could see that something was wrong. He was going paranoid over something.

“N-nolan are you okay?” You asked as you put your hand on his.

He pulled his hand away from your’s and smiled.

“Y-yeah I’m fine.” He said looking at you before looking back at Corey.

“Do you think DNA changes?” Nolan asked looking at Corey.

“If it’s damaged yeah a change in DNA could cause cancer.” Mason explained to Nolan.

“So organisms can change, organisms change.” Nolan said with a smile.

“They can change right in front of your eyes.” He said while looking at Corey.

Corey looked really uncomfortable and looked down for a second before looking back at Nolan.

“I don’t think this is on the test.” He said nervously towards Nolan.

“Yeah I wonder if organisms can change and then change back. Like…They can be two things at once.” Nolan said looking at Corey and then at you before looking back at Corey.

You looked at Nolan as Mason started to explain some really complicated stuff that only he would know. You could see that he was doing really bad. His eyes kept shifting back and forth and he looked down like he was thinking about something. You were about to say something to him when Corey started to speak.

“That’s definitely not on the test, or any high school test.” Corey said looking at Mason very confused.

“I wonder if……Any of us have changed. And if we did would there be any way to tell.” Nolan said looking straight at Corey.

“Nolan.” You said trying to capture his attention but when he as like this nothing could capture his attention.

“Like a DNA test?” Mason asked while looking at Nolan

“I was thinking a different type of test.” Nolan said looking down before looking back up.

Corey and Mason looked at each other while you looked at Nolan. And before you could stop him he had plunged his pen in Corey’s hand.

“What the hell is wrong with you?” Mason asked as he stood up.

“What the hell Nolan.” You said standing up and putting an arm around Corey

Nolan leaned forward and grabbed Corey’s hand and looked at it.

“Look? Look at him! Look!” Nolan yelled for the whole library.

“Look Y/N I told you he wasn’t normal.” He said before pushing Corey’s hand away.

Nolan turned around and walked away. While Mason was trying to convince the library that Corey was fine and that he just had a little scratch you ran after Nolan.

“Nolan!” You yelled as you saw him in the hallway.

“What the hell where you thinking.” You said walking up to him.

“I-I had to prove it Y/N I’m sorry.” He said turning around to look at you.

“What you had to prove to me that my brother wasn’t normal. Well guess what Nolan I already knew that.” You said angrily.

“You knew.” He said looking at him.

“Yeah I did. God what has happened to you. You think that my brother’s a monster and all those other people. You are the monster  I really hope you’re sorry.” You said angrily.

Why should I apologize for the monster I’ve become when no ones apologized for making me this way.” He said angrily looking at you.

“Because you are a good person that’s why you should apologize. The person who made you like this is clearly not going to apologize they made you like this for a reason. God I’m so stupid? I can’t believe I loved you.” You said crossing your arms.

“Y-you love me?” He asked confused.

“Yeah but now that you stabbed my brother int eh hand I’m not so sure.” You said looking down.

I think I’m in love with you too and you have no idea how much that fucking scares me.” Nolan said looking at you.

“You know you are scared of a lot of things.” You said with a little smile.

“I’m sorry for what I did to you’re brother I’m just really scared okay.” He said looking down.

“You don’t have to apologize to me for doing that. I know you are but you don’t have to be. My brother is trying to protect you guys okay.” You said as you took his hand.

“Okay I believe you.”

mypersonalkinkblr  asked:

yoooo, for the stuffed belly meme can we see either 12 (rocks) or 5 (fish)??

Hey so just did 12 but 5 was next on my list of most-asked so here ya go:

Fish would almost certainly have to have started out as eggs from an InCube assignment, unless (a) he swallows them accidentally while swimming on an alien planet or (b) they’re force fed to him by Bad Guys.

But if you’re talking alien fish, then this is another faaaave of mine. I would have to assume these alien fish, once hatched, are totally adapted to thrive in Dash’s insides and seem committed to making sure Dash knows they’re in there. So he’s got a massive, sloshing, heavy belly that practically ripples as the fish twist and writhe and literally swim in there. It wouldn’t necessarily be super painful (other than the usual strained ache of everything being full and stretched), but it certainly wouldn’t be comfortable either.

And I know I mentioned it up there but I gotta reemphasize that the noises coming from Dash’s abdomen would be like, ungodly with this particular infestation. Constant, deafening, liquid groans and fizzing bubbles and tight little whines and creaks. 

anonymous asked:

what do you think about remoraid and octilliery did someone ask about this?

Sit yourself down anon, because ol’ ommanyte here is about to get a bit ranty.

Don’t get me wrong, I love Octillery. Cephalopods are like my favourite animal group. And hey, remoraid is a pretty cool guy too, remoras are awesome. But the fallacy, the insinuation that a fish ‘evolves’ into an octopus rustles all 700 of my biology jimmies.

We’re not only taking about this bizzare vertebrate to invertebrate cross , but a split even further back on the evolutionary tree, in relation to embryological development (molluscs are protostomes, i.e. when the gut forms in the embryo, the first hole that forms becomes the mouth, where as in us and echinoderms (starfish etc), the deuterostomes, the first hole becomes the anus lol) 

And this isn’t the only instance of such biological blasphemy in the pokemon world. Clamperl, again a mollusc, is supposed to ‘evolve’ into one of two fish, again an invertebrate/vertebrate cross.

Do I have an explanation for this? Maybe. Perhaps scientists in the pokemon world are actually a bit shit, and perhaps we are just exposed to psuedoscience and myths a lot because we literally play the games from the perspectives of children… but I think these ‘evolutions’ so to speak could be explained by a mixture of poor observation and folklore.

Here is my real world example. Meet the Barnacle Goose (Branta leucopsis) and the Goose Barnacle (Pollicipes pollicipes)

Back in the day, people thought that the geese literally grew and were born from these barnacles

Haha what idiots right? Birds hatching from barnacles lol. But don’t be too quick to judge. Barnacle geese are migratory, flying to the arctic circle from temperate latitudes, such as  the british isles every summer to breed and raise their young. Europeans at the time would never actually witness the geese breeding and rearing chicks  the old fashioned eggy bird way, but just manifesting in large numbers to do goose stuff every winter. Perhaps they grew and matured under the sea as barnacles during the summer, and hatch and flock as geese when winter approached. The barnacles do look like geese heads, and for lack of a better explanation for all these birds materialising, the connection was made and stuck fast, forming the folklore that gives both the geese and the barnacles their names today. 

So, we have here a  real life example of people thinking invertebrates could grow into vertebrates. Could the case of Remoroid -> Octillery, and Clamperl -> Gorebyss/Huntail be a similar case of association and lack of observation? Perhaps Remoraid are migratory, and move away from coastal habitats just when Octillery juveniles hatch and appear. Maybe Octillery predate on mature remoraid. Both instances could result in remoraid being there in one moment, but not the next. If an octillery is there in the habitat to take it’s place then perhaps the connection could be made between the two.

And what of Clamperl? I always thought that the pink ‘pearl’ could in fact be a fish egg, with the bivalve clam pokemon a separate entity (perhaps the blue stuff?) Both huntail and gorebyss could lay their eggs within the clam, and upon maturation of the eggs  it appears that the clam itself has turned into the respective fish pokemon (both gorebyss and huntail could lay eggs in the same clam, but pheromones from adult conspecifics, i.e. from the deep sea scale/tooth are needed for the specific fish pokemon species to hatch? I dunno, that’s a story for another time lol) 

It could be that these evolutionary stories perpetuate in the pokemon world because biologists are actually terrible at making observations of pokemon life histories (well like they did think that there were only 150 pokemon and now there are like over 700, or the relatively recent discovery of baby pokemon - I know this is all game mechanic stuff, but still), or maybe, as a ten year old, you still believe that remoraid grow into octillery because your grandmother told you such stories when you were a tot, but in my head anyway, these associative myths can explain these ‘evolutions’.

(I know it doesn’t explain trainers who raise these pokemon in isolation from the wild but shhhhhh)
