Nobody is known to be credited for the discovery of Mercury, though Timocharis made the first recorded observation of Mercury in 265 BC and does not have an actual discovery date. Mercury also has many notable features that most likely caught Galileo's eye, like it’s similarity to our Earthen moon. Mercury has a variety of craters, ridges and ranged terrain. Mercury can be said as one of the most interesting planets in our solar
Uranus is the seventh planet from the sun in the solar system. It has the third largest mass in the solar system. It was William Herschel who discovered Uranus in 1781. In two years William thought it was a star or a comet. But then Uranus was accepted as a planet because of Johann Elert Bode’s observations.
The asteroids are orbiting around the sun mainly in what we call the asteroid belt - an area between the orbit of Mars and Jupiter. There are millions of asteroids in space, ranging in size from hundreds of metres across to as small as a pebble. Asteroids are made
The terms "old moon" and "new moon" are not interchangeable. The "old moon" is a waning sliver (which eventually becomes undetectable to the naked eye) until the moment it aligns with the sun and begins to wax, at which point it becomes new again. Half moon is often used to mean the first- and third-quarter moons, while the term. When a sphere is illuminated on one hemisphere and viewed from a different angle, the portion of the illuminated area that is visible will have a two-dimensional shape defined by the intersection of an ellipse and circle (where the major axis of the ellipse coincides with a diameter of the
Would we have an extreme runaway greenhouse effect and dry up like Venus? The concept of a habitable zone, sometimes referred to as the “Goldilocks Zone,” is vital to explaining the possibilities. WOULD MOVING EARTH CLOSER HAVE A BIG EFFECT? What would happen if Earth were to move a mile closer to the sun? Since the Earth’s orbit is an ellipse, not a circle, its distance from the sun varies from a minimum of 147.1 million kilometers each January to a maximum of about 152.1 million kilometers each July.
Similarities: The atmospheres of both have a lot of carbon dioxide. Micrometeorite impacts are avoided in both atmospheres. Differences: Venus’s atmosphere is much more dense, while Mars’s atmosphere is thin. Most water in Venus is in gas form in its atmosphere, while not in
Three facts that stuck out to me were how small we are compared to the whole universe, the quantity of stars, and finding constellations. The first fact of how small we actually are is amazing. We are just one small planet going into orbit when there are black holes and constellations and the butterfly effect. The quantity of stars is insane. No one could count all of the stars in the universe there are millions, billions, or maybe even trillions.
On the night of Wednesday, November 11, I went to the RLM. At 7:25 I observed Uranus at approximately 40 degrees in the east southeastern sky. It only appeared as a small whitish dot against a vast black background. I found it by looking directly into the lens where the astronomers had pointed the telescope in the sky. Discovered in 1781, Uranus is the third largest planet in the solar system.
Between 4.1 and 3.8 billion years ago, was a period known as the heavy bombardment period (Evolution of the Moon. 2012). During this period, the moon was hit with numerous impacts that left craters. 3.1 to 1 billion years ago, mare volcanism took place (Evolution of the Moon. 2012).
Was iron formed in the earth ? It is thought that the earth was once a part of the sun and then separated , so scientists thought that iron was formed in the sun but this supposition proved to be wrong because the surface heat temperature of the sun is 6000 Celsius degrees while the temperature of the core ranges from 15 million to 16 millions Celsius and in this degree , though high , is not enough to form an iron atom . The whole temperature of the solar system is not sufficient to produce just on atom from iron . The observable universe is composed of hydrogen (74%) and Helium (24%) ,while the other 105 elements form (2%).On studying the sun ,scientists found that it is only hydrogen and Helium that are there , it is known that hydrogen atoms fuse together to form helium and the sun nuclear reaction will remain as so till the sun runs out of hydrogen then begins to change into red giant where it will swallow the moon and the other planet . The Holy Quran records this cosmic event in its verses before science .
New discoveries were found on the once ninth planet and some don 't know what to do. All scientist do know is that Pluto is more than what meets the eye. One of the big discoveries was the temperture of the dwarf planet. The temperture is -380 degrees Fahrenheit about -229 degrees Celsius.
The discovery also challenges the accepted model for galaxy formation, which has most galaxies slowly bulking up by absorbing pieces of other galaxies, rather than growing internally. The fact that scientists are observing this galaxy at a time when the universe is only a bit over 1.4 billion years old is also strange. That means that in its infancy, the galaxy is already exhibiting this odd behavior. "This galaxy is undergoing a major baby boom, producing most of its stars all at once," Peter Capak of NASA 's Spitzer Science Center said. "If our human population was produced in a similar boom, then almost all of the people alive today would be the same
Starburst Galaxies Formation and Facts Starburst galaxies form stars much faster than normal galaxies. They can create new stars 1,000 times faster than regular galaxies. They are triggered when two galaxies pass by each other. Other ways that they can be created include galactic merging and if the galaxy has a galactic bar. All galaxies have a black hole in their center, and when they are extremely active, this can trigger rapid star formation.
Saturn is the second largest planet and sixth number planet of our solar system. Saturn is a gas giant made up of hydrogen and helium. It is big enough to hold more than 760 Earths within it, and is second massive planet after Jupiter, roughly 95 times Earth 's mass. However, Saturn has the lowest density among all the planets of solar system .It spins faster than any other planet except Jupiter which help Saturn with its magnetic field which is about 578 times more powerful than Earth 's. Although Saturn has at least 62 moons but its largest moon, Titan, is slightly bigger than Mercury, and is the second-largest moon in the solar system after Jupiter 's moon Ganymede (our moon is fifth largest).Although it is the most interesting planet
