The only way we can understand the cosmos is to find new and innovative ways to interpret the light we capture from it. Using the largest and most technologically advanced telescopes in the world, we peer deeper into space, further back in time, and see photons that have spent eons travelling to Earth. If we can get rid of all of the other light from closer objects, and zero in on this distant light, we can begin to understand what was present at the beginning. Using data from deep sky surveys conducted by the Hubble Space Telescope (HST), astronomers from...
As we push the limits of our technology, we naturally will find the biggest, the brightest, the smallest, the most extreme, and of course the most distant objects in the universe. We are at the time in history where we are beginning to see the edges of our universe in unprecedented detail. Eventually will will stop finding the biggest, brightest, and most distant, after which point our technology will serve to improve our precision and allow us to peer within these unique objects. Astronomers have used this incredible technology to discover the most distant galaxy in the universe, forming only...
The thing about black holes is that they are very dense. If we took the entire 2,000,000,000,000,000,000,000,000,000,000 Kg of the Sun (This is the real mass of the Sun) and turned it into a black hole, it would be about 6 Km in diameter. It is theorized that there are around 100 Million Black holes in the Milky Way Galaxy alone. But if they aren’t near a large reservoir of gas and dust, with their small size they are pretty harmless and invisible. The only way we could find them would be through their gravitational influence, which is hard to...
New research using the ESA’s Planck telescope has revealed that the first stars to shine in the universe sprouted up 100 Million years later than originally thought. Studying the universe is like piecing together a 13.8 Billion year story, from the time of the Big Bang to the present. We study objects in the local Galaxy to piece together the present state, and we look further from Earth to see back in time and visit the earlier chapters to determine the long term evolution of the universe. When the universe was 380,000 years old, it was large enough for the...
