ᯓ★ for dear t.me/MyColourfulPlace ㅤ Snow Penitentes 𐔌՞ ܸ.ˬ.ܸ՞𐦯 These ice pinnacles, called penitentes, form during the dry Andean summers on high-altitude glaciers through a self-amplification process of ablation by direct and reflected radiation. Sunlight will induce sublimation in various places on a glacier’s surface, producing depressions that focus sunlight and cause further sublimation. As the process con…

ᯓ★ for dear t.me/vxmpu3 ㅤ STEVE 𐔌՞ ܸ.ˬ.ܸ՞𐦯 STEVE — Strong Thermal Emission Velocity Enhancement — is an aurora-like glow that often accompanies the northern lights, yet is a distinct phenomenon, according to the American Geophysical Union (AGU). STEVE was discovered between 2015 and 2016, not by professional astronomers or physicists, but by citizen scientists in Canada chasing the aurora, according to the fir…

ᯓ★ for dear t.me/Retiredpoet ㅤ Nacreous Clouds 𐔌՞ ܸ.ˬ.ܸ՞𐦯 Ice polar stratospheric clouds (nacreous clouds) form at temperatures below the ice frost point, typically near −85 °C, which is colder than the average lower stratosphere temperature. The characteristic bright iridescent colours, resulting from diffraction and interference of light waves, suggest that the clouds are composed of similarly sized spherical…

ᯓ★ for dear t.me/Greammers ㅤ Fermi Bubbles 𐔌՞ ܸ.ˬ.ܸ՞𐦯 In 2010, gamma-ray observations by Fermi revealed previously unknown features in our galaxy that stretch halfway across the sky. Now called the Fermi Bubbles, these mysterious structures (magenta in the image above) emerge above and below the center of our galaxy, spanning a total length of about 50,000 light-years. The plane of our galaxy (shown in blue ab…

ᯓ★ for dear t.me/ItsJustNonesense ㅤ Fire Devil 𐔌՞ ܸ.ˬ.ܸ՞𐦯 A fire whirl, also commonly known as a fire devil, or, as a fire tornado, firenado, fire swirl, or fire twister, is a whirlwind induced by a fire and often (at least partially) composed of flame or ash. These start with a whirl of wind, often made visible by smoke, and may occur when intense rising heat and turbulent wind conditions combine to form whirl…

ᯓ★ for dear t.me/nek0diary ㅤ Volcanic Lightning 𐔌՞ ܸ.ˬ.ܸ՞𐦯 Volcanic lightning is a manifestation of electrical processes that occur in rising ash columns from explosive eruptions. Recent studies show the existence of three types of lightning: (1) vent discharges (small scale, short duration flashes right at the vent at the time of eruption), (2) near-vent lightning (medium scale, medium duration flashes above t…

ᯓ★ for dear t.me/twilightstay ㅤ Lunar Halo 𐔌՞ ܸ.ˬ.ܸ՞𐦯 The moon's halo or lunar halo is an optical illusion that causes a large bright ring to surround the moon. This striking and often beautiful halo around the moon is caused by the refraction of moonlight from ice crystals in the upper atmosphere. In effect, these suspended or falling flecks of ice mean the atmosphere is transformed into a giant lens causing a…

ᯓ★ for dear t.me/its_134340 ㅤ Magellanic Clouds 𐔌՞ ܸ.ˬ.ܸ՞𐦯 The Magellanic Clouds consist of two dwarf galaxies, the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC), which orbit the Milky Way galaxy. Visible primarily from the Southern Hemisphere, these clouds appear as patchy wisps of stars and have significant cultural and historical importance, having been observed by various civilizations, …

ᯓ★ for dear t.me/everythingicouldntbe ㅤ Blue Jets 𐔌՞ ܸ.ˬ.ܸ՞𐦯 Blue jets are beams of blue light propagating from the tops of active thunderclouds up to altitudes of ∼50 km. They resemble tall trees with quasi-vertical trunk and filamentary branches. Their apparent speeds are in the range of 10 s to 100 s km/s. Other events, having essentially lower terminal altitudes (<26 km), are named blue starters. These phen…

ᯓ★ for dear 彡شربتِ آبلیمو ㅤ Singing Ice 𐔌՞ ܸ.ˬ.ܸ՞𐦯 Singing ice is a natural phenomenon that occurs when ice sheets crack and groan due to changes in temperature, pressure, or internal stresses. These movements create vibrations that can produce a range of sounds, from low humming and rumbling to beautiful eerie creaking. In Antarctica, movements on the surface can often be translated into vibrations that propag…

ᯓ★ for dear t.me/whereskronk ㅤ Globular Clusters 𐔌՞ ܸ.ˬ.ܸ՞𐦯 Globular clusters are stable, tightly bound clusters of tens of thousands to millions of stars. They are associated with all types of galaxies. Globular clusters are typically much larger than open clusters and are tightly gravitationally bound. They are far more densely populated, with populations ranging from tens of thousands to millions of stars. …
