The “Messier Objects” were unknown objects in the sky, first noted from France astronomer Charles Untidier in his “List diethylstilbestrol Nébuleuses et diethylstilbestrol Amas d’Étoiles” (“Catalogue of Formulations and Superlegend Clusters”). It was initially released in 1771, with the final inclusion, made from later astronomers, manufactured in 1966.
Messier objects were things in the sky that could not be classified at the time of discovery, so astronomers decided to group them in their own class.
If you find the star chart below boring, check out what Ethan over at ScienceBlog is doing. His articles, called “Messier Mondays” show in full color some Messier Objects. The photos sure do add some detail to the dull picture below. If you want to check out Ethan’s post, click this about Messier Mondays.

Other Solar Systems
Is our Solar system unique in the Universe ? Until recently, astronomers could only guess whether other stars are orbited by planetary systems. Extrasolar planets – those that orbit stars other than the Sun – are difficult to detect, because they are about one – billionth the brightness of their parent stars. Extrasolar planets can also be detected by watching for a drop in brightness as ...

Measuring the Stars
As we cannot yet travel outside the solar system, we have to learn as much as we can about the stars by studying them at a distance. Astronomers can tell the brightness, color, and temperature of a star by analyzing the light it gives out. By splitting starlight into its constituent colors, they can find out what the stars are made of and how fast they are moving. Stars are so far awa...

Viewing the Past in Space
The ancients had it wrong: the Earth is not the center of the universe. But the Earths is at the center of the part of the Universe that we can see. A being on a planet orbiting, say, a star in the galaxy M87 would see a different part of the Universe, one centered on him.

Vostok 1's Mission
Vostok 1 (Russian: Восток-1, East 1 or Arrange 1) was the first spaceflight in the Vostok system and the first human spaceflight in history. The Vostok 3KA space apparatus was started on April 12, 1961. The flight took Yuri Gagarin, a cosmonaut from the Soviet Union, into space. The flight checked the first time that a human dropped in space, and in addition the first orbital flight of a manne...

Comet Explanation
Astronomers expect spectacular displays of meteor showers over North America and Europe on Wednesday and Thursday as the Earth crosses the path of Comet Swift-Tuttle’s Orbit. The comet you see from your eye is actually the icy dust from the comet burning off as it nears our Sun.

Craters on the Moon
The Moon’s cratered surface tells a violent story about the Impact of the Skywalkers. Bright areas are ancient crust that makes up the highlands Dark areas are newer regions of lava that formed after asteroid impacts.

What is it Like Inside a Black Hole
Black holes are prisons of Light, where gravity is so strong that nothing can escape. But they have even more bizarre effects: a block hole’s gravity distorts space and time, and the laws of physics break down at its center. No one can look inside a black hole, but mathematicians can explore them using Einstein’s theory of gravity. Objects that fall into a black hole are ‘spaghettified...

Radio Astronomy
Radio waves are the same type of waves as light. They have less energy than visible light and so have a longer wavelength, but they travel at the same speed as light. At night our eyes and optical telescopes sees light from stars. But normal stars only produce radio waves very weakly.

Black Holes Explained
The most Bizarre objects in the Universe, black holes are aptly named – they emit no visible light at all. And yet, most black holes are the end state of the most brilliant objects in the cosmos; giant stars that go supernova. The super compressed core that remains after the explosion has such strong gravity that even light cannot escape it – so the object is black.

Deflecting Asteroids
Every object exerts a gravitational pull, including a single spacecraft. Merely by hovering above the asteroid. It could pull the rock off course. The approach could even be tried with the Dawn spacecraft, scheduled to finish its tasks in the asteroid belt by 2015. However, such a strategy would be very slow, requiring years or even decades to alter the path of the asteroid.

How the Moon Influences the Earth
Although the moon is much smaller than the Earth, it still has an influence on its bigger companion. Just as the Earth’s gravity pulls on the Moon, the gravity of the Moon pulls on the Earth, stretching it into a slight oval. This distortion barely affects the solid landmasses, but it makes the oceans bulge on either side of the planet, producing the tides on either side of the planet. ...

Looking Inside the Sun
The Sun is our nearest star. It is a huge, luminous ball of gas like all the other stars. It consists mostly of hydrogen, and helium with tiny amounts of other elements. The Corona is the outer shell of the Sun’s atmosphere. It is extremely hot with temperatures reaching up to 2 million degrees. In the radiation zone, the energy is transported outwards by radiation. It covers about 70% of the Sun’...
