NEPTUNE is the world's first regional-scale underwater ocean observatory that plugs directly into the Internet. [1] NEPTUNE is the largest installation on the Ocean Networks Canada network of ocean observatories. Since December 2009, it has allowed people to "surf" the seafloor while ocean scientists run deep-water experiments from labs and ...
Image of Sirius A and Sirius B taken by the Hubble Space Telescope. Sirius B, which is a white dwarf, can be seen as a faint point of light to the lower left of the much brighter Sirius A. A white dwarf is a stellar core remnant composed mostly of electron-degenerate matter. A white dwarf is very dense: its mass is comparable to the Sun 's ...
Gaia is a space observatory of the European Space Agency (ESA), launched in 2013 and expected to operate until 2025. The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision, and the positions of exoplanets by measuring attributes about the stars they orbit such as their apparent magnitude and color.
The Orion correlation theory is a fringe theory in Egyptology attempting to explain the arrangement of the Giza pyramid complex . It posits that there is a correlation between the location of the three largest pyramids of the Giza pyramid complex and Orion's Belt of the constellation Orion, and that this correlation was intended as such by the ...
The Sombrero Galaxy (also known as Messier Object 104, M104 [4] or NGC 4594) is a peculiar galaxy of unclear classification [6] in the constellation borders of Virgo and Corvus, being about 9.55 megaparsecs (31.1 million light-years) [2] from the Milky Way galaxy. It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters ...
The Milky Way bar is made of nougat, topped with caramel and covered with milk chocolate. It was created in 1923 by Frank C. Mars and originally manufactured in Minneapolis, Minnesota. The name and taste derived from a then-popular malted milk drink ( milkshake) of the day, not after the astronomical galaxy.
Leo I is a dwarf spheroidal galaxy in the constellation Leo. At about 820,000 light-years distant, it is a member of the Local Group of galaxies and is thought to be one of the most distant satellites of the Milky Way galaxy. It was discovered in 1950 by Albert George Wilson on photographic plates of the National Geographic Society – Palomar ...
S2, also known as S0–2, is a star in the star cluster close to the supermassive black hole Sagittarius A* (Sgr A*), orbiting it with a period of 16.0518 years, a semi-major axis of about 970 au, and a pericenter distance of 17 light hours (18 Tm or 120 au) – an orbit with a period only about 30% longer than that of Jupiter around the Sun, but coming no closer than about four times the ...
