💫 SpaceX made history today! It successfully performed an abort test of its Crew Dragon spacecraft. . Shortly after liftoff, the empty Crew Dragon capsule that will house astronauts in the future separated from the Falcon 9 rocket 🚀 before the rocket exploded 💥 to mimic an emergency or catastrophic event. . Delayed by one day due to bad weather, the launch today marks the first time that SpaceX successfully performed this critical test. . Did you see the launch? Leave a comment! . 🚀 Like this content?

The four Galilean moons were named after characters from Greek myths and their relationships with Zeus or Jupiter in Roman mythology: Io (upper left), Europa (upper right), Ganymede (lower left), and Callisto (lower right). Io can be easily recognized by its yellow surface, Europa by its cryovolcanism, Ganymede being the largest moon in the solar system, and Callisto.

The extraordinary life of Leonardo DaVinci was exemplified by his interests in many fields including art, science, anatomy, transportation, and the physical world. Considering that he is equally known for creating the Mona Lisa, drawing the Vitruvian Man, or The Last Supper is a testament to his deep curiosity and talent.

A continuous source of the amino acids that make proteins, nucleic acids in DNA and RNA (lower right), and lipids that form membranes due to the hydrophobic effect (lower left), would most likely have been the hydrothermal vents (upper left) at the boundaries of continental plates. The primordial soup or the “warm little pond” that Darwin suggested that all life formed from may have indeed been the entire ocean in which these chemical reactions could have taken place.

Nebulas can be studied for star formation by telescopes using submillimeter astronomy. This branch of astronomy focuses microwaves - instead of radio waves by radio telescopes and visible light by optical telescopes - to study extremely cold objects that do not emit highly energetic radiation.

Dark nebulae called Bok globules represent an area of intense research in astrophysics. While they are composed of cosmic dust that obscures light behind them, these cocoons contain hydrogen and helium that are usually the site for the formation of binary star systems.

Gravitational darkening occurs in extremely fast rotating stars such as Vega, Altair, and Achernar. Centrifugal force results in the bulging and thus lower gravity at the the equator. Lower gravity results in lower temperatures and thus a less brighter surface than the poles of the star.

Astrocytes are star-shaped glial cells in the brain and the spinal cord. They are important in forming the blood-brain barrier that acts as a sieve to allow small molecules such as glucose and amino acids to pass through while preventing large toxins from entering neuronal cells. Astrocytes are also crucial in providing nutrients to neurons and regulating certain biochemical processes such as propagation of ion waves across the cell membrane.
