Latest Galileo Galilei Stories
In the folklore of physics, no story is better known than the tale of Galileo dropping balls from the Leaning Tower of Pisa and proving that gravity accelerates all objects equally regardless of their masses or composition. But was Galileo correct?
Like cell phones or the Internet in recent history, the telescope's introduction in the early 17th Century had a swift and lasting impact on the world.
Famed physicist Stephen Hawking said Thursday that Pope John Paul II tried to discourage him and other scientists attending a cosmology conference at the Vatican from trying to figure out how the universe began.
From his vantage point atop the highest peak in southern Arizona, Father Jose Funes is lining up the Vatican telescope for a night of observation, probing the processes that lead galaxies to form and stars to be born.
The planet Venus is best known for the thick layers of clouds that veil its surface from view by telescopes on Earth. But the veil has holes, and a New Mexico State University scientist plans on using a solar telescope to peer through them to study the weather on Venus.
A Vatican cardinal said Thursday the faithful should listen to what secular modern science has to offer, warning that religion risks turning into "fundamentalism" if it ignores scientific reason.
Everyone knows the Vatican is interested in Heaven but it may come as a surprise to some that it is also interested in the heavens. In a sleepy lakeside village away from the noise and haste of Rome, the Vatican is helping to train tomorrow's astronomers -- regardless of their religious beliefs.
This weekend Mercury, Venus and Saturn are going to crowd together in a patch of sky no bigger than your thumb. Astronomers call it a "conjunction" and it's going to be spectacular. The show begins on Saturday evening, June 25th. Step outside and look west toward the glow of the setting sun.
Thirty-five years after Moon-walking astronauts placed special reflectors on the lunar surface, scientists have used these devices to test Albert Einstein's general theory of relativity to unprecedented accuracy. The findings may help to explain physical laws of the universe and benefit future space missions.
Film director and exploration enthusiast James Cameron (Titanic, Aliens) gave Stanford graduate student Kevin Hand a chance to search for "alien" life close to home -- a mere 2 miles below the ocean surface -- as part of Cameron's IMAX documentary, Aliens of the Deep, which opens today.
Galileo Probe -- The Galileo probe was an unmanned probe sent by NASA to study the planet Jupiter and its moons. Named after the astronomer Galileo Galilei, it was launched on October 18 1989 by the Space Shuttle Atlantis and arrived at Jupiter on December 7 1995. Galileo's launch had been significantly delayed by the hiatus in Space Shuttle launches that occurred after the Space Shuttle Challenger disaster, and new safety protocols that were implemented as a result forced Galileo to use...
Sunspot -- A sunspot is a region on the Sun's surface (photosphere) that is marked by a lower temperature than its surroundings, and intense magnetic activity. Although they are blindingly bright, at temperatures of roughly 5000 Kelvin, the contrast with the surrounding material at some 6000 Kelvin leaves them clearly visible as dark spots. Interestingly, if they were isolated from the surrounding photosphere they would be brighter than an electric arc. History Apparent references...
