The visible-light (left) and infrared (right) views of the Trifid Nebula—a giant star-forming cloud of gas and dust located 5,400 light-years away in the constellation Sagittarius Stars are thought to form inside giant clouds of cold molecular hydrogen — giant molecular clouds roughly 300,000 times the mass of the Sun ( M ☉ ) and 20 ...
In October 2018, the existence of the Kordylewski clouds was reported to have been confirmed by the Royal Astronomical Society, [2] [3] [4] even though, earlier, in 1992, the Japanese Hiten space probe, which passed through the Lagrange points to detect trapped dust particles, did not find an obvious increase in dust levels above the density in ...
As a result, these nebulae are incredibly faint, taking hours of exposure to capture. These nebulae clouds, an important component of the interstellar medium, are composed of dust particles, hydrogen and carbon monoxide and other elements." [22] They are particularly prominent in the direction of both the north and south celestial poles. The ...
Nacreous clouds, also known as "mother-of-pearl" clouds, are high-altitude clouds that form in the stratosphere, typically at altitudes of 15 to 25 kilometers, and are most commonly observed in ...

Satellites captured a beautiful phenomenon called Von Karman clouds off the coast of Mexico on May 8, and this occurrence has many wondering why and how these swirls are appearing over the Pacific ...
All stars are formed from collapsing clouds of gas and dust, often called nebulae or molecular clouds. Over the course of millions of years, these protostars settle down into a state of equilibrium, becoming what is known as a main-sequence star. Nuclear fusion powers a star for most of its existence.
Lunar Reconnaissance Orbiter Wide Angle Camera image of Reiner Gamma Another view of Reiner Gamma swirls Mare Ingenii Swirls east of Firsov crater, from Apollo 10. Lunar swirls are enigmatic features found across the Moon's surface, which are characterized by having a high albedo, appearing optically immature (i.e. having the optical characteristics of a relatively young regolith), and (often ...
