Gigantic Jets over Himalayan Mountains

Explanation: Yes, but can your thunderstorm do this? Pictured here are gigantic jets shooting up from a thunderstorm last week toward the Himalayan Mountains in China and Bhutan. The composite image captured four long jets that occurred only minutes apart. Gigantic jets, documented only in this century, are a type of lightning discharge that occurs between some thunderstorms and the Earth's ionosphere high above them. They are an unusual type of lightning that is much different from regular cloud-to-cloud and cloud-to-ground lightning. The bottoms of gigantic jets appear similar to a cloud-to-above strike called blue jets, while the tops appear similar to upper-atmosphere red sprites. Although the mechanism and trigger that cause gigantic jets remains a topic of research, it is clear that the jets reduce charge imbalance between different parts of Earth's atmosphere. A good way to look for gigantic jets is to watch a powerful but distant thunderstorm from a clear location.

ASTRONOMY - Ou4: The Giant Squid Nebula

Ou4: The Giant Squid Nebula

Explanation: Squids on Earth aren't this big. This mysterious squid-like cosmic cloud spans nearly three full moons on planet Earth's sky. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula's bipolar shape is distinguished here by the telltale blue emission from doubly ionized oxygen atoms. Though apparently surrounded by the reddish hydrogen emission region Sh2-129, the true distance and nature of the Squid Nebula have been difficult to determine. Still, one investigation suggests Ou4 really does lie within Sh2-129 some 2,300 light-years away. Consistent with that scenario, the cosmic squid would represent a spectacular outflow of material driven by a triple system of hot, massive stars, cataloged as HR8119, seen near the center of the nebula. If so, this truly giant squid nebula would physically be over 50 light-years across.

ASTRONOMY - Animation: Black Hole Destroys Star

Explanation: What happens if a star gets too close to a black hole? The black hole can rip it apart -- but how? It's not the high gravitational attraction itself that's the problem -- it's the difference in gravitational pull across the star that creates the destruction. In the featured animated video illustrating this disintegration, you first see a star approaching the black hole. Increasing in orbital speed, the star's outer atmosphere is ripped away during closest approach. Much of the star's atmosphere disperses into deep space, but some continues to orbit the black hole and forms an accretion disk. The animation then takes you into the accretion disk while looking toward the black hole. Including the strange visual effects of gravitational lensing, you can even see the far side of the disk. Finally, you look along one of the jets being expelled along the spin axis. Theoretical models indicate that these jets not only expel energetic gas, but also create energetic neutrinos -- one of which may have been seen recently on Earth.

SANTé/MEDECINE - Le CBD

Le potentiel du CBD est reconnu des scientifiques et apprécié des consommateurs. Le CBD peut être consommé sous des formes aussi diverses que variées : en e-liquide pour les cigarettes électroniques, en huile pour les applications cutanées, en gélules pour une prise quotidienne ou encore en fleurs pour l’incorporer dans vos recettes de cuisine favorites. Quelles que soient les méthodes d’assimilation, un spécialiste du CBD en France partage les multiples promesses de cette molécule. Entre autres : c’est un remède efficace contre le stress, l’anxiété et même les états dépressifs ;

on lui prête aussi des vertus antalgiques pour atténuer les douleurs chroniques et les courbatures ;

elle réduit l’inflammation, notamment sur le plan digestif et diminue les troubles gastro-intestinaux;

on lui attribue également des pouvoirs antioxydants qui participent au renforcement du système immunitaire.

Idéal pour contrer des effets négatifs du stress, le CBD agit beaucoup sur l’humeur permettant d’être moins irritable, de ne plus ressentir cette impression d’être submergé ou dépassé, de se sentir libéré de certaines tensions, qu’elles soient physiques ou psychologiques et enfin de mieux dormir.

ASTRONOMY - Prominences and Filaments on the Active Sun

Explanation: This colorized and sharpened image of the Sun is composed of frames recording emission from hydrogen atoms in the solar chromosphere on May 15. Approaching the maximum of solar cycle 25, a multitude of active regions and twisting, snake-like solar filaments are seen to sprawl across the surface of the active Sun. Suspend in the active regions' strong magnetic fields, the filaments of plasma lofted above the Sun's edge appear as bright solar prominences. The large prominences seen near 4 o'clock, and just before 9 o'clock around the solar limb are post flare loops from two powerful X-class solar flares that both occurred on that day. In fact, the 4 o'clock prominence is associated with the monster active region AR 3664 just rotating off the Sun's edge.

ASTRONOMY - RCW 85

Explanation: From the 1960 astronomical catalog of Rodgers, Campbell and Whiteoak, emission region RCW 85 shines in southern night skies between bright stars Alpha and Beta Centauri. About 5,000 light years distant, the hazy interstellar cloud of glowing hydrogen gas and dust is faint. But detailed structures along well-defined rims within RCW 85 are traced in this cosmic skyscape composed of 28 hours of narrow and broadband exposures. Suggestive of dramatic shapes in other stellar nurseries where natal clouds of gas and dust are sculpted by energetic winds and radiation from newborn stars, the tantalizing nebula has been called the Devil's Tower. This telescopic frame would span around 100 light-years at the estimated distance of RCW 85.
