CG4: A Ruptured Cometary Globule

Can a gas cloud grab a galaxy? It’s not even close. The “claw” of this odd looking “creature” in the featured photo is a gas cloud known as a cometary globule. This globule, however, has ruptured. Cometary globules are typically characterized by dusty heads and elongated tails. These features cause cometary globules to have visual similarities to comets, but in reality they are very much different. Globules are frequently the birthplaces of stars, and many show very young stars in their heads. The reason for the rupture in the head of this object is not yet known. The galaxy to the left of the globule is huge, very far in the distance, and only placed near CG4 by chance superposition. via NASA

Wikipedia article of the day for July 26, 2021

Wikipedia article of the day is Siege of Calais (1346–1347). Check it out: Article-Link Summary: The Battle of Caen on 26 July 1346 was an assault on the French-held town by a force of archers and men-at-arms, part of an invading English army under King Edward III during the Hundred Years’ War. This force, nominally commanded by the Earls of Warwick and Northampton, was eager for plunder, and attacked against orders, before the rest of their army was in position. Caen was garrisoned by 1,000–1,500 soldiers and a large number of armed townsmen, commanded by Grand Constable of France Raoul, the Count of Eu. The town was captured in the first assault; over 5,000 of the ordinary soldiers and townspeople were killed and a small number of nobles were taken prisoner. After sacking the town for five days, the army marched to the River Seine, and by 12 August they were 20 miles (32 kilometres) from Paris. After turning north they heavily defeated the French at the Battle of Crécy two weeks later, and commenced the successful siege of Calais the following week.
