... I have felt A presence that disturbs me with the joy Of elevated thoughts; a sense sublime Of something far
more deeply interfused, Whose dwelling is the light of setting suns, And the round ocean and the living air, And the blue
sky, and
in the mind of man; A motion and a spirit, that impels All thinking things, all
objects of all thought, And rolls through all things.
More accurate distances between the most common type of «planetary nebulae» and the Earth can be estimated simply with three sets of data: firstly, the size of the
object on the
sky taken from the latest high resolution surveys; secondly, an accurate measurement of how bright the
object is
in the red hydrogen - alpha emission line; and thirdly, an estimate of the dimming toward the nebula caused by so called interstellar - reddening.
Guyon adds that the system will help astronomers to study the
skies more efficiently, by bringing large
objects, such as nearby galaxies, into focus all at once, and by allowing
more distant
objects to be studied
in a single snapshot.
Sky watchers have catalogued
more than 16,000
objects larger than about 10 centimeters, most of them
in low Earth orbit, at altitudes of 200 to 2,000 kilometers.
For instance, look at the recent use of the Cosmic Evolution Survey, using the Hubble Space Telescope to study gravitational lensings [
in which the gravitational pull of galaxies and dark matter bends the light from
more distant
objects]
in an area of the
sky nine times the apparent surface area of the full moon.
Viewed from a planet at Earth's orbital distance around Alpha Centauri A, stellar companion B would provide
more light than the full Moon does on Earth as its brightest night
sky object, but the additional light at a distance greater than Saturn's orbital distance
in the Solar System would not be significant for the growth of Earth - type life.
Lead author Dr. Danail Obreschkow, from The University of Western Australia (UWA) node of the International Centre for Radio Astronomy Research (ICRAR), said that ten billion years ago the Universe was full of clumpy galaxies, but these developed into
more regular
objects as they evolved; the majority of stars
in the
sky today, including our five billion - year - old Sun, were probably born inside these clumpy galaxies.
The bigger the telescope's aperture, the
more light is collected and therefore the dimmer and
more distant the
objects in the night
sky that can be imaged.
Now that Kepler is exploring other patches of
sky in its current mission, called K2, it can no longer follow up on Tabby's Star, but future telescopes may help unveil
more secrets of this mysterious
object.
In addition to taking 1,100 years to complete its orbit around the sun, the object is blisteringly chilly, which makes sense seeing as it's located in the Kuiper Belt where our sun is no more than a bright pinprick in the sk

This cloud is the bright Milky Way patch slightly above the center of our image; among many other Deep
Sky objects (clusters and nebulae) one can find 10
more Messier
objects in this image.
The NVSS is expected to produce a catalog of
more than two million radio - emitting
objects in the
sky, and it is the first
sky survey sensitive to linearly polarized emission from radio sources beyond our own Milky Way galaxy.
The company says Photolemur recognizes
objects, faces, trees,
sky, foliage and
more; understands the type of photo (landscape, portrait, macro) and applies the appropriate fix based on its knowledge of processing hundreds of thousands of photos
in the past.
