energy, deep into the darkness because light didn’t even exist neither did gravity and the universe was never even created. The energy expanded and the temperature got intense and then started to expand. This is what cause the universe, millions of galaxies, stars, and solar systems. Scientists discovered that the space in the Universe was expanding and what cause this was the Big Bang. The evidence can be proven wrong but because of this, what had caused the red shift that was heard in the sky? Scientists

results they hoped would help answer one of the most contentious issues in astronomy of the 20th century – the question of the distance scale of the universe. But there was some unease when the result was announced. According to the report, other galaxies were close enough that, extrapolating backwards from their current rate of recession and making adjustments for the influence of gravity, they all would have been together (that is, the Big Bang would have occurred) as recently as 8 billion years

enveloping the Andromeda galaxy, our nearest massive neighbor, is about six times larger and 1,000 times more massive than previously measured. The dark, nearly invisible halo stretches about a million light-years from its host galaxy, halfway to our own Milky Way galaxy. One of the most common types of galaxies in the universe. Halos are the gaseous atmospheres of galaxies. The properties of these gaseous halos control the rate at which stars form in galaxies according to models of galaxy formation, explained

have much more to discover! There is a big possibility that in one of those planets life could exist. Another big clue that scientist have discovered is that there are many galaxies in space and we live in one. The galaxy that Earth is located at is called the Milky Way Galaxy. A galaxy can contain many planets just like our galaxy can contains over billions of planets. Furthermore, scientists have this big prediction in which they think that in about ten years they will prove themselves

dioxide and several other gaseous elements that have created and sustained life as we know it. The universe is a vast space made of matter that varies from the smallest cosmic particle to a massive galaxy. Within one of billions of galaxies is home to planet earth, which is one of 7 planets in the Milky Way Galaxy, all orbiting a star. Based on what human life is conscious of, Earth is the only residence of intelligent life in the universe. Could planet Earth be the only planet able to sustain intelligent

than previously thought, driving gas from galaxies and sending them to an early death by depriving them of the material to make new stars. The study of 11,000 galaxies shows their gas -- the lifeblood for star formation -- is being violently stripped away on a widespread scale throughout the local Universe. Toby Brown, leader of the study and PhD candidate at ICRAR and Swinburne University of Technology, said the image we paint as astronomers is that galaxies are embedded in clouds of dark matter that

distant galaxy. But in some places where point sources of radio waves were found, no visible source other than a stellar-looking object was found (it looked like a point of a star). These objects were called the quasi-stellar radio sources or quasars for short. Later, it was found these sources could not be stars in our galaxy, but must be very far away as far as any of the distant galaxies seen. We now think these objects are the very bright centers of some distant galaxies, where

Universe went from the size of an atom to the ginormous galaxy we have that is continuously growing. According to the Big Bang Theory the universe appeared as a singularity. Singularities are thought to exist at the core of black holes. These zones of infinite density are called "singularities." Our universe is thought to have begun extremely small, infinitely hot, and infinitely dense. As time

the remains of a dwarf spheroidal galaxy that is in the process of merging with the Milky Way. It is the largest galaxy visible from the Earth, in terms of the area of the night sky covered. The stream covers over 100 square degrees, and possibly as much as 1,000 square degrees. Despite its proximity to the solar system and the solid angle that it consequently covers, the stream contains only a few hundred thousand stars. The low surface brightness of the galaxy may have militated against its detection
