Happy #StPatricksDay! Celebrating with a wave of green aurora that @Astro_JeffW was lucky enough to see in person during his 2016 mission on the space station (@ISS). The dancing lights of the aurora provide stunning views, but also capture the imagination of scientists who study incoming energy and particles from the sun. Aurora are one effect of such energetic particles, which can speed out from the sun both in a steady stream called the solar wind and due to giant eruptions known as coronal mass ejections or CMEs.
[No Audio] Earth’s radiation belts, two doughnut-shaped regions of charged particles encircling our planet, were discovered more than 50 years ago, but their behavior is still not completely understood. Now, new observations from NASA’s Van Allen Probes mission show that the fastest, most energetic electrons in the inner radiation belt are not present as much of the time as previously thought. The results are presented in a paper in the Journal of Geophysical Research and show that there typically isn’t as much radiation in the inner belt as previously assumed — good news for spacecraft flying in the region.
The 3-dimensional radiation belt model in the visualizations above was constructed by propagating electron flux measurements, corresponding to a given time and distance from Earth measured by the Van Allen Probes, along a 3-dimensional structure of magnetic dipole field lines.

Stretched Loops: When an active region rotated over to the edge of the sun, it presented us with a nice profile view of its elongated loops stretching and swaying above it (March 8/9, 2017). These loops are actually charged particles (made visible in extreme ultraviolet light) swirling along the magnetic field lines of the active region. The video covers about 30 hours of activity. Also of note is a darker twisting mass of plasma to the left of the active region being pulled and spun about by magnetic forces.

Sorting through layers: Several small sunspots appeared this week, giving us a chance to illustrate their sources. The first image is a magnetogram or magnetic image of the sun's surface. The MDI instrument can observe where positive and negative particles are moving toward or away from strong magnetic areas. These active regions have stronger magnetic fields and appear as strongly black or white. The yellow image shows the surface in filtered light, and there the same active regions appear as dark, cooler splotches called sunspots. Higher up in the sun's atmosphere, the golden image (in extreme ultraviolet light) shows arches of light above the active regions, which are charged particles spinning along magnetic field lines. Note that they all align very well with each other. Magnetic forces are the dynamic drivers here in these regions of the sun.

LIFTOFF! The Falcon 9 rocket lifted off at 9:39 a.m. EST, and the Dragon cargo vehicle is on orbit heading to the International Space Station with an arrival scheduled for Wednesday, Feb. 22. It will deliver science and supplies to the crew living and working on station. Follow along at: http://www.nasa.gov/spacex
A solar prominence rose up along the edge of the sun and twisted and churned for about two days before falling apart (Jan. 23-24, 2017). The dynamic action was generated by competing magnetic forces. The images were taken in a wavelength extreme ultraviolet light that observes activity close to the solar surface, perfect for capturing prominences, which are notoriously unstable clouds of plasma suspended above the sun.

Part 1: What’s up in the sky this month? Use Venus and Mars to find the Zodiacal Light. On February 1st the crescent moon joins the planets Venus, Mars and Uranus in the southwest sky just after sunset.

Got stopped on the way 2 times for #drugs 😂 and was searched ofcourse. Although the NL authorities were very professional nothing beats our local heroes 😂. Protecting and serving till their last dying breath😂
Doing some dips in may new @teamgysfitness t-shirt, that baby is just so soft and fit I can't help but to touch myself 😂 Let's be sexy together go get your own and use SIMEON15 for your 15%disc 😏
Anyways 😂 notice how I tilt my body to the front and I squeeze my butt cheeks real hard 😂
If you do great you are paying attention 😏 this will help you out alot in stabilising your body and putting an emphasis on the pectoral.
I don't really see the point In going all the way down as it puts too much stress on your shoulder joints.
I also combine this with incline pushups. Again I squeeze my ass 😂, seriously this helps with keeping the body tight and puts emphasis on the targeted muscle so do it now and stay safe 😂✌!
