Herbig Ae/Be star
A Herbig Ae/Be star, also called a Herbig star, is a young intermediate-mass star of spectral type A or B still contracting toward the main sequence.
Herbig–Haro object
A Herbig–Haro (HH) object is a small patch of glowing nebulosity in a star-forming region, produced where supersonic jets from a newborn star shock-heat the surrounding gas and dust.
Herbimycin A
Herbimycin A is a benzoquinone ansamycin antibiotic produced by the soil bacterium Streptomyces hygroscopicus, first isolated in 1979 and later found to inhibit the chaperone Hsp90.
Hercules Dwarf Galaxy
Hercules is an ultra-faint dwarf spheroidal galaxy satellite of the Milky Way, about 132 kpc away in the constellation Hercules, discovered in 2007 in Sloan Digital Sky Survey data, and debated as tidally disrupted.
Hercules X-1
Hercules X-1 (Her X-1) is an eclipsing X-ray binary pulsar in the constellation Hercules, discovered by the Uhuru satellite in 1971, accreting matter from the star HZ Herculis.
Hercules–Corona Borealis Great Wall
The Hercules–Corona Borealis Great Wall, or Great GRB Wall, is a proposed clustering of gamma-ray bursts, reported in 2014 and possibly the largest structure in the universe.
Heritability estimation
Heritability estimation is a family of statistical methods in genetics that quantify the proportion of variation in a trait attributable to genetic differences, using twin or genomic data.
Heritability of IQ
The heritability of IQ, also called heritability of intelligence, is the proportion of variation in intelligence attributable to genetic differences, roughly 50 percent in twin and adoption studies.
Herkimer diamond
The Herkimer diamond, also called Little Falls Diamond, is a doubly terminated quartz crystal found in Herkimer County, New York; it is quartz, not true diamond.

Herman Wold
Herman Wold (1908–1992) was a Norwegian-born Swedish statistician and econometrician, professor at Uppsala, known for the Wold decomposition of stationary time series and the partial least squares methods.
Herman Z. Cummins
Herman Z. Cummins (1933–2010) was an American experimental physicist who invented laser Doppler velocimetry and photon correlation spectroscopy, studied phase transitions by light scattering, and taught at City College of New York.
