Explanation: A supermoon sets over the metropolis of Philadelphia in this twilight snapshot captured on November 14 at 6:21am Eastern Standard Time. Within hours of the Moon's exact full phase, that time does correspond to a lunar perigee or the closest point in the Moon's elliptical orbit around our fair planet. Slightly bigger and brighter at perigee, this Full Moon is still flattened and distorted in appearance by refraction in atmospheric layers along the sight-line near the horizon. Also like more ordinary Full Moons, it shines with the warm color of sunlight. Joined by buildings along the Philadelphia skyline, the perigee full moonlight is reflected in the waters of the mighty Schuylkill River.

Explanation: Faster than a speeding bullet, more powerful than a locomotive, and able to leap tall buildings in a single bound, this Soyuz rocket stands on the launch pad at Baikonur Cosmodrome in Kazakhstan on November 14.Beyond it rises a supermoon, but fame for exceptional feats of speed, strength, and agility is not the reason November's Full Moon was given this popular name. Instead, whenever a Full Moon shines near perigee, the closest point in itselliptical orbit around Earth, it appears larger and brighter than other more distant Full Moons, and so a supermoon is born. In fact, November's supermoon was the second of three consecutive supermoons in 2016. It was also the closest and most superest Full Moon since 1948. Meanwhile, the mild mannered Soyuz rocket is scheduled to launch its Expedition 50/51 crew to the International Space Station today, November 17.

Astronomy picture of the day - 2016 November 16 - The Heart and Soul Nebulas

Explanation: Is the heart and soul of our Galaxy located in Cassiopeia? Possibly not, but that is where two bright emission nebulas nicknamed Heart and Soul can be found. The Heart Nebula, officially dubbed IC 1805 and visible in the featured image on the right, has a shape reminiscent of a classical heart symbol. Both nebulas shine brightly in the red light of energized hydrogen. Several young open clusters of stars populate the image and are visible here in blue, including the nebula centers. Light takes about 6,000 years to reach us from these nebulas, which together span roughly 300 light years. Studies of stars and clusters like those found in the Heart and Soul Nebulas have focused on howmassive stars form and how they affect their environment.

Expressões populares portuguesas - Gatos pingados

Significado: Tem sentido depreciativo usando-se para referir uma suposta inferioridade (numérica ou institucional), insignificância ou irrelevância. 

Origem: Esta expressão remonta a uma tortura procedente do Japão que consistia em pingar óleo a ferver em cima de pessoas ou animais, especialmente gatos. Existem várias narrativas ambientais na Ásia que mostram pessoas com os pés mergulhados num caldeirão de óleo quente. Como o suplício tinha uma assistência reduzida, tal era a crueldade, a expressão "gatos pingados" passou a denominar pequena assistência sem entusiasmos ou curiosidade para qualquer evento.
