Sentences with phrase «angular size of»

The angular size of an astronomical object is its apparent size in the sky from our perspective.

The relationship between the angular size of the smallest details that can be distinguished (θ), the wavelength (λ) and the diameter (D) is given by: θ ≈ λ / D.

This phenomenon increases the apparent brightness and angular size of the lensed objects, making it easier to study sources that would be otherwise too faint to probe.

Another result that we don't really understand is that we don't see any temperature fluctuations in the microwave background on scales larger than 60 degrees [the angular size in the sky of the fluctuations].

Basically, the distant ripples appear to shrink as the universe expands, so researchers can infer the age of the cosmos from their angular size on the sky.

This list is every galaxy with an angular size greater than 1.8 arcminutes within 7.5 degrees of the centre of the cluster which at a distance of 52 million light years corresponds to every galaxy with a diameter greater than 30 thousand light years within 7 million light years from the centre.

The list of accomplishments is far too large to fit within one article, but they include: the first search for extraterrestrial intelligence; creation of the Drake equation; discovery of flat galactic rotation curves; first pulsar discovered in a supernova remnant; first organic polyatomic molecule detected in interstellar space; black hole detected at the center of the Milky Way; determination of the Tully - Fisher relationship; detection of the first interstellar anion; measurement of the most massive neutron star known; first high angular resolution image of the Sunyaev - Zel» Dovich Effect; discovery of only known millisecond pulsar in a stellar triple system; discovery of pebble - sized proto - planets in Orion, and the first detection of a chiral molecule in space.

The new technique is similar to that used by land surveyors on earth, who measure both the physical and angular — or «apparent» — size of a distant object, to calculate its distance from Earth.

Giving the advantage of its high - angular resolving power (~ 7mas), TMT will be able to resolve a dozen large Trans - Neptunian objects and ~ 50 - 100 Trojan asteroids, providing a good estimate of their size.

And the angular scale of the EHT is astonishing; it will have the power to resolve something the size of a grape lying on the surface of the moon.

Note that this effect of size on the perceived contrast can not be explained by the finite resolution of the visual system, because we used disks with angular diameter much larger than that of the Airy disk, and the effect was exactly the same for disks of the two different diameters we used.

The new simulations performed by Southwest Research Institute (SwRI) and University of California at Santa Cruz (UCSC) researchers show that a single impact by a Mars - sized object in the late stages of Earth's formation could account for an iron - depleted Moon and the masses and angular momentum of the Earth - Moon system.

Concerning atmospheric angular momentum, it's overall size tells that it can not vary enough to explain variability in LOD beyond about 1 ms. Actual calculations of AAM confirm its role.

The density will continue to increase without limit, as the gravitational force increases due to the inverse square law of gravity, and the rotation will speed up, to conserve the angular momentum of the initial state, as the size decreases, so the moment of inertia continues to decline, and angular velocity increases to keep I. omega ^ 2 constant.
