Hubal (هُبَل)
Hubal (هبل) was the chief idol of pre-Islamic Mecca, a red carnelian human figure inside the Ka'ba consulted by divination arrows, traditionally imported by Amr ibn Luhayy, destroyed at the 630 conquest, and distinct from Allah.
Hubba Shyamal
Hubba Shyamal (Shyamal Das, 1966–2011) was a Hooghly district gangster called the 'Dawood Ibrahim of Hooghly'; arrested at a Salt Lake multiplex in 2005, found dead in the Baidyabati canal in 2011, subject of the 2024 film Hubba.
Hubbard Glacier
Hubbard Glacier is a tidewater glacier in southeast Alaska flowing into Disenchantment Bay and Russell Fiord near Yakutat, the largest tidewater glacier in North America, which has advanced rather than retreated since 1895.
Hubbard model
The Hubbard model is a lattice model of interacting electrons that hop between sites and pay an on-site repulsion, the leading model for cuprate superconductivity introduced in 1963.
Hubbell Incorporated
Hubbell Incorporated is an American manufacturer of electrical and utility products for grids, buildings, and industry, founded by Harvey Hubbell II in 1888 and headquartered in Shelton, Connecticut.
Hubble (film)
Hubble (Hubble 3D, IMAX: Hubble) is a 2010 43-minute IMAX 3D documentary directed by Toni Myers, narrated by Leonardo DiCaprio, covering the Hubble telescope and the May 2009 STS-125 Atlantis servicing mission, grossing $52.5 million in the US.
Hubble (lunar crater)
Hubble is an 81.84 km wide impact crater on the Moon centered at 22.29°N, 86.91°E, officially approved by the IAU in 1964 and named for American astronomer Edwin Powell Hubble (1889–1953).
Hubble bubble hypothesis
The Hubble bubble hypothesis proposes that the Milky Way sits inside a large underdense region whose outflow makes the locally measured expansion rate of the universe appear higher.
Hubble constant
The Hubble constant (H₀) is the present-day expansion rate of the universe, discovered by Edwin Hubble in 1929 and measured in kilometers per second per megaparsec.
Hubble Deep Field
The Hubble Deep Field is a small patch of sky in Ursa Major that the Hubble Space Telescope imaged for ten days in 1995, revealing about 3,000 distant galaxies.
Hubble diagram
A Hubble diagram is a plot of distance or brightness against redshift for astronomical objects, used to trace the expansion history of the universe and the dark energy driving it.
Hubble flow
The Hubble flow is the uniform expansion of space that carries galaxies away from one another, so a galaxy's recessional velocity grows in proportion to its distance.
Hubble Frontier Fields
The Hubble Frontier Fields was a Hubble and Spitzer program begun in 2013 that used six galaxy clusters as natural telescopes to magnify the most distant galaxies.
Hubble radius
The Hubble radius, the boundary of the Hubble sphere, is the distance at which galaxies recede at light speed in an expanding universe, about 10 billion light-years today.
Hubble sequence
The Hubble sequence is a morphological classification scheme for galaxies published by Edwin Hubble in 1926, ordering galaxies into ellipticals, spirals, and irregulars; its two-pronged layout is the tuning-fork diagram.
Hubble Space Telescope
The Hubble Space Telescope, also known as the Hubble Telescope, is a 2.4-meter NASA/ESA observatory launched in 1990 that observes ultraviolet, visible, and near-infrared light from above Earth's atmosphere.
Hubble tension
The Hubble tension is the significant disagreement between direct local measurements of the Hubble constant, near 73, and lower early-universe values near 67, a serious challenge to the standard ΛCDM model.
Hubble Ultra-Deep Field
The Hubble Ultra-Deep Field is a 2004 Hubble Space Telescope image of a small patch of Fornax showing at least 10,000 galaxies, many extremely distant.
Hubble volume
A Hubble volume is the region of the universe within the Hubble radius, the distance at which recession from the observer reaches the speed of light.
Hubble's law
Hubble's law, also called the Hubble–Lemaître law, is the cosmological observation that a galaxy's recessional velocity is proportional to its distance, discovered by Edwin Hubble in 1929.
Hubei (湖北)
Hubei (湖北), a central Chinese province on the middle Yangtze, capital Wuhan; 185,900 km², 58.11 million people (2025), GDP 6.27 trillion yuan, home of the Three Gorges Dam at Yichang.
Hubei Energy Group
Hubei Energy Group, formed in 2005 and listed on the Shenzhen Stock Exchange, is a Chinese state-owned energy company in Wuhan controlled by China Three Gorges Corporation.
Hubei Ezhou power station
Hubei Ezhou power station (湖北能源鄂州发电厂) is a coal-fired power station in Ezhou, Hubei, China, whose 3,960 MW make it the largest thermal power plant in Hubei Province.
Hubei Hongtai High-Quality Development Fund (湖北洪泰高质量发展基金)
The Hubei Hongtai High-Quality Development Fund (湖北洪泰高质量发展基金) is a government-guided private equity fund in Wuhan, China, announced in 2020 with a planned scale of 30 billion yuan.
Hubei Humanoid Robot Mother Fund (湖北省人形机器人母基金)
The Hubei Humanoid Robot Mother Fund (湖北省人形机器人母基金) is a government-backed fund of funds for the humanoid-robot industry, registered in Wuhan in 2025 and managed by Changjiang Growth Capital.
