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.

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.

Explanation: Why is it so warm in northern North America? Usually during this time of year -- mid-November -- temperatures average as much as 30 degrees colder. Europe is not seeing a similar warming. One factor appears to be an unusually large and stable high pressure region that has formed over Canada, keeping normally colder arctic air away. Although the fundamental cause of any weather pattern is typically complex, speculation holds that this persistent Canadian anticyclonic region is related to warmer than average sea surface temperatures in the mid-Pacific -- an El Niño -- operating last winter. North Americans should enjoy it while it lasts, though. In the next week or two, cooler-than-average temperatures now being recorded in the mid-Pacific -- a La Niña -- might well begin to affect North American wind and temperature patterns.
