Hubble Space Telescope - The Best Images From Over Two Decades In Orbit (by Best0fScience)
This video is absolutely breathtaking!
We choose to go to the moon
I am not a United States citizen, but people from all over the world was somehow affected by the acts of this outlier man.
This man pushed to get to the moon, pushed to gain knowledge , pushed to challenge, even though he recognized that this act was more of faith and vision, and he did not know the outcomes.
You cannot believe how many things have been developed thanks to the space program, and we use it in daily basis.
Things like: scratches resistant lenses, the shoe insoles, smoke detectors, water filters, cordless tools, satellites to predict the weather, GPS, were developed thanks to the space program.
If I know how to make my way to an unknown place, is thanks to the GPS developed thanks to the space program.
If I have clean water, is thanks for water filters developed thanks by the space program.
Please feel free to reblog and add something you use thanks to the space program.

How simple ideas lead to scientific discoveries
I love the idea that different branches of science are called fields of study. Most people think of science as a closed, black box, when in fact it is an open field, and we are all explorers.
ISS030-E-078095 (6 Feb. 2012) —- One of the Expedition 30 crew members aboard the International Space Station took this nighttime photograph of much of the eastern (Atlantic) coast of the United States. Large metropolitan areas and other easily recognizable sites from the Virginia/Maryland/Washington, D.C. area spanning almost to Rhode Island are visible in the scene. Boston is just out of frame at right. Long Island and the Greater Metropolitan area of New York City are visible in the lower right quadrant. Large cities in Pennsylvania (Philadelphia and Pittsburgh) are near center. Parts of two Russian vehicles parked at the orbital outpost are seen in left foreground.
Look with detail this piece! It’s awesome!
Have a great day everybody!
That is this number: 7 000 000 000 000 000 000 000 000 000
Nowadays there is a popular application called fMRI (where the f stands for functional), used to identify which part of the brain is working when any type of activity is taken place. The principle is simple. When a part of the brain becomes active, blood flow increases into that part of the brain and that is detected in an MRI scan as a change in contrast on the image.
The image above is the result of the next experiment:
A subject was told to move their left hand for ten seconds and then not to move for others ten seconds and so on. An image of the brain was acquired every second of the experiment.
If you are moving your left hand during a fMRI; at the end of the experiment, the analysis of the data will show that the right motor cortex of your brain will be illuminated as active, and this is because when you are moving your left hand, the blood flow is increased in that part of the brain, and that small changes in blood flow are detected by MRI as a change in contrast of the different images. What happens in the background is that the scans acquired are then analyzed in search for small changes in every image, and where small changes are detected consistently, that means there is activity.
At the bottom of the image, there is a green graph tracing the activity of a selected area of the brain during the whole experiment. You can see the selected area on the brain of the middle in the second row. This graph is going up, and going down. When it goes up means activity, and “no activity” when it goes down.
One clinical application of fMRI is the detection of active areas of the brain, before a neurosurgical intervention where brain tissue needs to be removed. In that way, when a tumor needs to be removed, it can be removed as extensively as possible, while preserving the active adjacent areas.
Colpophyllia natans, known as boulder brain coral and large-grooved brain coral, is a species of stony coral found primarily in the Caribbean Sea and the Gulf of Mexico. It inhabits the slopes and tops of reefs, to a maximum depth of fifty metres. It is characterised by large, domed colonies, which may be up to two metres across, and by the meandering network of ridges and valleys on its surface. The ridges are usually brown with a single groove, and the valleys may be tan, green, or white and are uniform in width, typically 2 centimetres. The polyps only extend their tentacles at night.
Last week I went to an aquarium with lots of Corals, and to my surprise, there was one coral with shape of a Brain, It was mind-boggling for me.
This is a scan of a brain using an MRI. There are 120 sagital slices put together in a video.
I made this video time ago, when I used to hear Van Halen. I was looking at the scans and I thought : “Hey, if the transition of this slices could make some sounds, I believe the sound it’s something very close to the song 1984 by Van Halen”
Above, the South Pole marker which was unveiled on 1 January 2011! This amazing creation takes the art of Pole marker design to a whole new level! Not a bad idea, since this year is the 100th anniversary of when Roald Amundsen’s team first set foot on this bit of the world.
A new marker for the Geographic South Pole is put in place each year on January the first. The South Pole is covered by a moving ice sheet, so at the end of the year the marker is about 10 metres from where it started.
The previous markers are kept in a display case in the South Pole station and a new marker designed and made from brass by the station expeditioners.
This is inspiring! Imagine in 1911 withouth GPS, ar any special device to tell where you are, using analog devices, and guided by stars. In 1911 Roald Amundsen and Captain Robert Scott and his teams,embodied (I believe) the most human characteristic: Curiosity.
Amazing!
This is a set of scans of some fruits and vegetables in a Magnetic Resonance Imaging (MRI).
- Cucumber.
- Pomegranate.
- Onion.
- Tangerine.
- Starfruit or Carambola.
- Kiwi (axial slice).
- Kiwi (sagital slice).
- Tomato (axial slice).
- Tomato (sagital slice).
Magnetic Resonance Imaging is a medical imaging technique to acquire images from the human body —vegetables and fruits also =) —, and it is completely harmless (no radiation). If well applied, you can virtually scan any part of the human body.
Those scans were made, when I was in college, being able to play around with an MRI. Yeah MRIs are fun =)
