The suppression of that light makes it easier for astronomers to then uncover the images of the planets.
FORBES: Astronomers Conduct 'Reconnaissance' Of Another Solar System
Overall, the competition produced incredible results for astronomers, and the sponsors of the contest were pleased with the result.
But for astronomers, it's something more - a chance to engage laymen and enthusiasts with the studies of the cosmos.
Those periods, though, are measurable only because they are short enough for astronomers to have seen the comets in question more than once.
Taken together, the observational and modeling results imply that many extrasolar systems harbor distantly orbiting worlds, though such planets are tough for astronomers to detect at the moment, researchers said.
Indeed, one principal purpose of the Bolshoi simulation is to compute and model the evolution of dark matter halos thereby rendering the invisible visible for astronomers to study, and to predict structures that astronomers could then seek to observe.
It caters for amateur astronomers and holds lectures, short talks, debates and observing sessions.
Is its current flyby distance a problem for radar astronomers?
That was another challenge for the astronomers: Because they didn't know the asteroid's rotation period, they didn't know when it would wax and wane, and when it would grow too faint to see.
For example, astronomers recently discovered a galaxy that is over 13 billion light years away from Earth.
FORBES: Why Marco Rubio Needs To Know That The Earth Is Billions Of Years Old
For now, astronomers will use Friday's fly-by to bounce radar beams off 2012 DA14's surface, hoping to learn more about its motion and structure.
CNN: Meteor shows why it is crucial to keep an eye on the sky
One of the main tools that astronomers have for understanding objects in the universe is spectroscopy.
FORBES: Astronomers Conduct 'Reconnaissance' Of Another Solar System
The nova is providing a unique stellar laboratory, shedding light on processes normally confined to supernovae that are too slow for Earth-bound astronomers to learn from quickly.
"It will be a sad day when it makes its last observation, but the data that it has collected during its lifetime will keep astronomers busy for years, " he told BBC News.
And nowadays, we have so much data with these vast surveys with millions of galaxies and it's just impossible for small teams of astronomers to sort through them by hand, by eye, and classify them.
Astronomers have debated for years whether a middleweight category exists, with evidence several times suggesting they do but then being refuted.
For the first time, astronomers have determined the size and shape of the highly-charged region of radio emission surrounding the black hole.
X-rays are easier to pinpoint than gamma rays, so BeppoSAX was able to give astronomers a position for the bursts that was accurate enough to aim a big optical telescope at.
Though Einstein's framework remains intact so far, "the study is significant for the way observations by astronomers are helping to identify new, extreme cases" to test his general theory of gravity, said Dr. Wang.
So far, few astronomers have conducted searches for Dyson spheres and none has been successful.
ECONOMIST: Is it time for a new approach to finding extraterrestrials?
He and later astronomers spent decades looking for the missing planet within the orbit of Mercury which, they were convinced, explained what was going on.
Well, it turns out that astronomers don't know for sure what it is either.
Secondly, the detection of multiple planets demolishes once and for all the lingering doubts of some astronomers that the single planets found around other stars are not planets at all, but small, faint components in otherwise conventional binary star systems.
For a while after the Mariner 4 mission, astronomers had grown more upbeat about the planet.
And thanks to the National Capital Astronomers and the Northern Virginia Astronomy Club for their help in setting up their telescopes for the public to use.
But astronomers have figured out a clever way for Hubble to "observe" the effects of the transit on the light from the sun: by looking at the moon.
At about the same time, a team of professional astronomers was pulling off a similar trick for a planet the size of Jupiter in orbit around a star 32m times farther from Earth than the sun.
ECONOMIST: Astronomers may have found their first Saturn lookalike
Besides requiring astronomers to dream up a new mnemonic for their stellar classification, the existence of a grey area between stars and planets reveals the extent to which the processes of planetary and stellar formation are still a mystery.
Astronomers say the sun has been relatively quiet for some time.
WSJ: Solar Flare: Sun Flare Leads to Solar Storm Reaching Earth
He is particularly excited by the prospect of being able to dedicate a large telescope to the search for supernovae, since these are used as intergalactic yardsticks by astronomers.
