The idea that astronomers might one day receive signals from aliens is no longer considered absurd by astronomers.
Very few objects smaller than 100 meters (300ft) across have been spotted and catalogued by astronomers.
The farther out astronomers peer into the universe, the longer it has taken the light they see to reach Earth.
There are other lensed background galaxies in the image as well, and the astronomers used those to get the mass of 146-ig.
During the next two weeks, you can help build a map of global light pollution, assisting scientists and astronomers as they monitor the loss of virgin night skies.
Having spent a lot of cash in recent years, physicists and astronomers are now finding they do not have enough money to use the very facilities they paid to have built.
Other astronomers seem impressed with Gregory's analysis.
This is probably not what many astronomers would expect.
The stars above us are a priceless heritage—not only for astronomers but for all humans.
But Hubble isn't just giving us extraordinary pictures, it's helping astronomers unlock the secrets of the universe.
The bigger the asteroid, the greater the potential cataclysm. The reflectivity of the surface — what astronomers call albedo — tells how easily it can be detected.
This near view offers astronomers a relatively local test bed for studying intense star formation processes that are usually hard to observe in detail because of their great distance from us.
He is the best one of those astronomers.
Beginning in 1645, astronomers monitoring the sun observed no sunspots for 70 years.
The new theory of the universe was ripped to pieces by many of the world's leading astronomers.
The data it gathered, like much of the information all space telescopes collect, was initially recorded and banked, awaiting the time astronomers could break it down and analyze it.
Space scientists and astronomers have made progress.
The Mayans were one of the foremost astrologers (and astronomers) of the ancient world.
The Hubble observations have added important clues to the story of this interacting foursome, allowing astronomers to determine when the encounter began and to predict a future merger.
How do astronomers predict meteor showers?
To astronomers, flat means that the usual rules of geometry are observed - light travels in straight lines, not curves.
NASA radar astronomers picked up its track on Friday and were immediately able to narrow its position to within one kilometer — 50 times better than their previous best estimate.
The source of earth's oceans has been a subject for debate among astronomers for decades.
The dark star--named Nemesis by astronomers--is thought to be a brown dwarf" that spins round the Sun in an orbit so large it is measured in light years, the distance light travels in a year, equivalent to about 6,000 billion miles.
The rare space event has also drawn many US astronomers to the eastern China, one of the best sites to watch it.
Eris was thought to be bigger than Pluto until Nov. 6, when astronomers got a chance to recalculate Eris' size.
The centre of the Milky Way is crowded with stars; so crowded, in fact, that astronomers think that one must plunge into this black hole every 100, 000 years or so.
Now astronomers want to know whether the maths is correct.
New discoveries about Uranus excited planetary astronomers in 1977.
