Cosmic latte

Cosmic latte, or Cappuccino Cosmico, is the average color of light from galaxies in the observable universe, a pale beige computed by astronomers in 2002.

Cosmic microwave background

The cosmic microwave background (CMB), also called relic radiation, is leftover light from the universe at 380,000 years old, detected as microwaves near 2.725 K.

Cosmic microwave background spectral distortions

Cosmic microwave background spectral distortions are departures of the CMB's spectrum from a perfect blackbody, caused by energy released after thermalization fails in the early universe.

Cosmic neutrino background (νB)

The cosmic neutrino background (CνB), or relic neutrinos, is the population of neutrinos left over from the first second of the universe, now about 1.95 K.

Cosmic Origins Spectrograph

The Cosmic Origins Spectrograph (COS) is an ultraviolet spectrograph installed on the Hubble Space Telescope in May 2009 to study how galaxies, stars, and planets formed.

Cosmic Par1

Cosmic Par1, L.P. is a West Hollywood, California venture capital fund formed in 2021, associated with investor Elad Gil, which raised $250.2 million from two investors.

Cosmic Princess Kaguya!

Cosmic Princess Kaguya! (超かぐや姫!) is a 2026 Netflix original anime film, Shingo Yamashita's feature directorial debut, reimagining The Tale of the Bamboo Cutter with Vocaloid-producer music by ryo (supercell) and others, produced by Studio Colorido and Studio Chromato.

Cosmic ray

Cosmic rays, also called cosmic radiation, are high-energy charged particles, mostly protons, arriving from space; Victor Hess discovered them by balloon in 1912, and their origins remain debated.

Cosmic Ray Energetics and Mass Experiment

The Cosmic Ray Energetics and Mass (CREAM) experiment is a particle-physics payload measuring cosmic-ray nuclei from hydrogen to iron, first flown over Antarctica in 2004.

Cosmic ray spallation

Cosmic ray spallation, also called the X-process, is the fragmentation of heavy nuclei struck by high-energy cosmic rays, and it is the accepted origin of nearly all cosmic ray lithium, beryllium, and boron.

Cosmic rays

Cosmic rays are high-energy charged particles, mostly protons, that move through space at nearly the speed of light and constantly bombard Earth from outside the atmosphere.

Cosmic shear

Cosmic shear is the correlated distortion of distant galaxies' apparent shapes by weak gravitational lensing, used to map dark matter and first detected independently by four groups in 2000.

Cosmic shear peak statistics

Cosmic shear peak statistics count the local maxima of weak-lensing mass maps as a function of peak height, probing non-Gaussian information beyond two-point statistics to constrain cosmology.

Cosmic Sin

Cosmic Sin is a 2021 American sci-fi action film directed by Edward Drake, starring Bruce Willis and Frank Grillo as generals leading a preemptive Q-bomb strike on zombie-like aliens in 2524; it scored 3% on Rotten Tomatoes.

Cosmic Songs

Cosmic Songs (Písně kosmické) is an 1878 poetry collection by the Czech writer Jan Neruda, whose 38 poems celebrate human discovery of the universe and became an immediate success.

Cosmic string

A cosmic string is a hypothetical one-dimensional topological defect, an extremely thin line of concentrated energy predicted to have formed during symmetry-breaking phase transitions in the early universe.

COSMIC study

COSMIC study: Dutch randomized trial (COPD and Seretide: a Multi-Center Intervention and Characterization, Thorax 2005) of fluticasone withdrawal in 373 COPD patients; also the Karolinska COSMIC omics cohort, NCT02627872.

Cosmic Thing

Cosmic Thing is the B-52's' fifth studio album, released June 27, 1989 on Reprise and produced by Don Was and Nile Rodgers. Their comeback after guitarist Ricky Wilson's 1985 death, it hit #3 on Billboard, went quadruple platinum, and spawned "Love Shack" and "Roam".

Cosmic time

Cosmic time, also called cosmological time, is the time coordinate of the FLRW metric, the proper time measured by observers at rest with the universe's expansion.

Cosmic variance

Cosmic variance is the fundamental sampling uncertainty in cosmology that comes from observing only one Universe, limiting measurements like the cosmic microwave background power spectrum.

Cosmic-ray anisotropy

Cosmic-ray anisotropy is the deviation of cosmic-ray arrival directions from perfect isotropy, with tiny contrasts of 10⁻⁴ to 10⁻³ at TeV energies and a dipole rising with energy.

Cosmic-ray composition and abundances

Cosmic-ray composition and abundances describe what cosmic rays are made of: about 90% hydrogen, 9% helium, and 1% heavier nuclei, with secondary elements like boron created en route by collisions.

Cosmic-ray neutron sensing

Cosmic-ray neutron sensing (CRNS) is a non-invasive ground-based method that measures soil moisture by counting low-energy neutrons from cosmic rays, with a footprint of hundreds of meters demonstrated in 2008.

Cosmic-ray observatory

A cosmic-ray observatory is a scientific installation, on the ground, in the atmosphere, or in space, that detects high-energy cosmic particles and measures their energy, direction, and composition.

Cosmic-ray propagation and confinement

Cosmic-ray propagation and confinement is the study of how charged cosmic rays diffuse through Galactic magnetic fields, remaining confined for millions of years before detection at Earth.

Cosmic-ray source candidates

Cosmic-ray source candidates are the astronomical objects proposed to accelerate cosmic rays, with supernova remnants the leading Galactic candidate and active galactic nuclei and gamma-ray bursts candidates for ultra-high energies.

Cosmic-ray spectrum and spectral features

The cosmic-ray energy spectrum is the flux of high-energy particles arriving at Earth, which falls as a power law with named features: the knee, ankle, and suppression.

CosmicFlows

CosmicFlows is a series of catalogs of galaxy distances and peculiar velocities, led by R. Brent Tully at the University of Hawaiʻi, running from Cosmicflows-1 (2008) to Cosmicflows-4 (2023).

Cosmicism

Cosmicism is the literary philosophy of H. P. Lovecraft holding that human laws, interests, and emotions have no meaning at cosmic scale; related to cosmic nihilism but distinct from Russian cosmism.

Cosmicomics

Cosmicomics (Le cosmicomiche) is a 1965 short story collection by Italo Calvino. Each story opens with a scientific fact and is narrated by Qfwfq, a being as old as the universe.
