Stephenson 2-18 (abbreviated to St2-18), also known as Stephenson 2 DFK 1 or RSGC2-18, is an enigmatic red supergiant (RSG) or possible extreme red hypergiant (RHG) star in the constellation of Scutum. It lies near the open cluster Stephenson 2, which is located about 5.8 kiloparsecs (19,000 light-years) away from Earth in the Scutum–Centaurus Arm of the Milky Way galaxy, and is assumed to be one of a group of stars at a similar distance, although some sources consider it to be an unrelated or foreground red supergiant. It is among the largest known stars, one of the most luminous red supergiants, and one of the most luminous stars in the Milky Way.

Size of a neutron star is up to 15 to 25 miles, which is not much bigger than a small city. But if you take just 1 teaspoon material of neutron star, its weight will be equal to Mount Everest. The total mass of a neutron star is greater than 1.4 solar masses.

The "photon sphere" is a location where gravity is so strong that light can travel in circles. Photons orbit the black hole at the distance of the photon sphere. A photon could leave the back of your head, go once around the black hole, and be seen by your eye. Yes! You can see the back of your head.

اخترشناسان می‌گویند یک جرم اسرارآمیز که فقط ۴۰۰۰ سال نوری از زمین فاصله دارد، شبیه هیچ چیزی نیست که تاکنون در فضا دیده شده است. آنها فکر می‌کنند که این شیء می‌تواند یک ستاره نوترونی یا یک کوتوله سفید حاصل از هسته‌های فرو پاشیده ستارگان با یک میدان مغناطیسی فوق‌العاده قدرتمند باشد که به عنوان “مگنتار” یا “مغنااختر” نیز شناخته می‌شود.

Energy doesn't disappear, it just switches places. The chemical potential energy in a full phone battery is transformed into electrical energy for your phone, which is turned into heat and light for display, which is why you can read this on your screen! The energy itself never disappears. That doesn't stop your battery needing a recharge though.

Hawking radiation is black-body radiation that is theorized to be released by black holes because of quantum effects near the black hole event horizon. It is named after the physicist Stephen Hawking, who developed a theoretical argument for its existence in 1974.

Sometimes water seems to defy the laws of physics, holding together despite the attempts of gravity or even the pressure of heavy objects to break it apart.

This is the power of surface tension, a property that makes the outer layer of a body of water (and some other liquids) act like a flexible membrane. Surface tension arises because water molecules bond loosely with one another. Due to the weak bonds between them, the molecules at the surface experience an inward pull from the molecules beneath them. Water will stick together until the forces pulling them apart overtake the strength of those weak bonds, and break the surface.

Our galaxy, the milky way, is so large that it would take 100,000 years to get across its diameter if you were to travel at the speed of light. scientists estimate our galaxy is just one of two trillion in the observable universe.
