The brown-dwarf desert is a theorized range of orbits around a star within which brown dwarfs are unlikely to be found as companion objects. [1] This is usually up to 5 AU around solar mass stars. The paucity of brown dwarfs in close orbits was first noted between 1998 and 2000 when a sufficient number of extrasolar planets had been found to ...
The object was compared to works by artist John McCracken (1934–2011), who lived in the southwest desert, believed in the existence of extraterrestrials, and expressed an interest in leaving behind a piece of artwork in the desert. [33] The object resembled the metallic monoliths McCracken made, and was described as "nearly identical" to ...

Las Vegas police said on the social platform X that members of its search and rescue unit found the otherworldly object over the weekend near Gass Peak, part of the vast Desert National Wildlife ...
The Allende meteorite is the largest carbonaceous chondrite ever found on Earth. The fireball was witnessed at 01:05 on February 8, 1969, falling over the Mexican state of Chihuahua . [ 1 ] After it broke up in the atmosphere , an extensive search for pieces was conducted and over 2 tonnes (2.2 tons) were recovered.
In astronomy, the terms object and body are often used interchangeably. However, an astronomical body or celestial body is a single, tightly bound, contiguous entity, while an astronomical or celestial object is a complex, less cohesively bound structure, which may consist of multiple bodies or even other objects with substructures.
Objects may have been discovered without distance determination, and were found subsequently to be the most distant known at that time. However, object must have been named or described. An object like OJ 287 is ignored even though it was detected as early as 1891 using photographic plates, but ignored until the advent of radiotelescopes.
It was expected to detect between 150 and 200 new exoplanets, and was able to study rare systems, such as planets with extreme eccentricity, and objects in the "brown dwarf desert". [ 28 ] [ 29 ] The collected data was used as a statistical sample for the theoretical comparison and discovery of rare systems. [ 30 ]
