It’s Friday…which seems like a great excuse to take a look at some awesome images from space.
First, let’s start with our home planet: Earth.
This view of the entire sunlit side of Earth was taken from one million miles away…yes, one MILLION! Our EPIC camera on the Deep Space Climate Observatory captured this image in July 2015 and the picture was generated by combining three separate images to create a photographic-quality image.
Next, let’s venture out 4,000 light-years from Earth.
This image, taken by the Hubble Space Telescope, is not only stunning…but shows the colorful “last hurrah” of a star like our sun. This star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star’s remaining core. Our sun will eventually burn out and shroud itself with stellar debris…but not for another 5 billion years.
The material expelled by the star glows with different colors depending on its composition, its density and how close it is to the hot central star. Blue samples helium; blue-green oxygen, and red nitrogen and hydrogen.
Want to see some rocks on Mars?
Here’s an image of the layered geologic past of Mars revealed in stunning detail. This color image was returned by our Curiosity Mars rover, which is currently “roving” around the Red Planet, exploring the “Murray Buttes” region.
In this region, Curiosity is investigating how and when the habitable ancient conditions known from the mission’s earlier findings evolved into conditions drier and less favorable for life.
Did you know there are people currently living and working in space?
Right now, three people from three different countries are living and working 250 miles above Earth on the International Space Station. While there, they are performing important experiments that will help us back here on Earth, and with future exploration to deep space.
This image, taken by NASA astronaut Kate Rubins shows the stunning moonrise over Earth from the perspective of the space station.
Lastly, let’s venture over to someplace REALLY hot…our sun.
The sun is the center of our solar system, and makes up 99.8% of the mass of the entire solar system…so it’s pretty huge. Since the sun is a star, it does not have a solid surface, but is a ball of gas held together by its own gravity. The temperature at the sun’s core is about 27 million degrees Fahrenheit (15 million degrees Celsius)…so HOT!
This awesome visualization appears to show the sun spinning, as if stuck on a pinwheel. It is actually the spacecraft, SDO, that did the spinning though. Engineers instructed our Solar Dynamics Observatory (SDO) to roll 360 degrees on one axis, during this seven-hour maneuver, the spacecraft took an image every 12 seconds.
This maneuver happens twice a year to help SDO’s imager instrument to take precise measurements of the solar limb (the outer edge of the sun as seen by SDO).
Thanks for spacing out with us…you may now resume your Friday.

Quantum Entanglement - The Quantum Source of Space-Time. Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently - instead, a quantum state must be described for the system as a whole. Quantum mechanics governs the world of the small - the weird realm in which particle can be in many places at the same time, and can simultaneously spin both clockwise and anticlockwise. Gravity governs the Universe at large - from the fall of an apple to the motion of planets, stars and galaxies. The theory holds that gravity is geometry: particles are deflected when they pass near a massive object not because they feel a force but because space and time around the object are curved. Both theories have been abundantly verified through experiment, yet the realities they describe seem utterly incompatible. And from Van Raamsdonk standpoint, all that’s needed is ‘entanglement’: the phenomenon that many physicists believe to be the ultimate in quantum weirdness. Entanglement lets the measurement of one particle instantaneously determine the state of a partner particle, no matter how far away it may be - even on the other side of the Milky Way. In conclusion, it seems that entanglement is the essential ingredient that knits space-time together into a smooth whole - not just in exotic cases with black holes. If any two particles are connected by entanglement, the physicists suggested, then they are effectively joined by a wormhole. And vice versa: the connection that physicists call a wormhole is equivalent to entanglement. They are different ways of describing the same underlying reality.
1. Cognitive Dissonance - the idea that when we hold two conflicting thoughts or beliefs, we unconsciously adjust to make one fit with the other. My social psychology professor gave an example of a student who values studying all the time, but slacks off when it comes to their favorite television show. So the student tells herself that watching the television helps her study later when it really doesn’t. However, telling herself that helped her eased the anxiety.
2. Hallucinations are common - one third of people report experiencing hallucination at some point in time. Similarly, normal people often have paranoid thoughts. So when was the last time you hallucinated?
3. The Placebo effect - this is when you think that something like a drug has an effect on you when really it doesn’t. It’s your thoughts that actually resulted in you getting better.

nasa-official!!!!!! why is it that the Rosette nebula only appears red in some photos? Is that how it appears optically, or is that just how it appears in one of the spectra that we read it in?
Well whenever you see red in nebulae, thats typically due to hydrogen being excited. The Rosette Nebula is actually classified as an H II region. H II (singly ionized hydrogen) regions are caused by some source of energy, kicking the electron out of the hydrogen atom and keeping it out.
So Rosette is definitely red. To strengthen this effect, pictures are often taken using a Hydrogen-Alpha filter which (you guessed it) only lets the light in from this transition!!! But, sometimes people want to look at what’s going on in the nebula in different wavelengths too
Timeline of the Far Future. While scientific predictions of the future can never be absolutely certain, present understanding in various fields allows for the prediction of far future events, if only in the broadest strokes. These fields include astrophysics, which has revealed how planets and stars form, interact, and die; particle physics, which has revealed how matter behaves at the smallest scales; evolutionary biology, which predicts how life will evolve over time; and plate tectonics, which shows how continents shift over millennia. All projections of the future of the Earth, the Solar System, and the Universe must account for the second law of thermodynamics, which states that entropy, or a loss of the energy available to do work, must increase over time. Stars eventually must exhaust their supply of hydrogen fuel and burn out. Close encounters gravitationally fling planets from their star systems, and star systems from galaxies. Eventually, matter itself is expected to come under the influence of radioactive decay, as even the most stable materials break apart into subatomic particles. Current data suggest that the universe has a flat geometry (or very close to flat), and thus, will not collapse in on itself after a finite time, and the infinite future potentially allows for the occurrence of a number of massively improbable events, such as the formation of a Boltzmann brain. This timeline coverS events from roughly eight thousand years from now to the furthest reaches of future time. A number of alternate future events are listed to account for questions still unresolved, such as whether humans will become extinct, whether protons decay, or whether Earth will survive the Sun’s expansion into a red giant.

Sooo I got myself some new glasses together with my dad today and I’m really happy about them! I’ll pick them up in two weeks and honestly I can’t wait~
