| Astronomers discover oldest star: Formed shortly after the Big Bang 13. 7 billion years ago Posted: 09 Feb 2014 05:08 PM PST A team of astronomers has discovered the oldest known star in the Universe, which formed shortly after the Big Bang 13.7 billion years ago. The discovery has allowed astronomers for the first time to study the chemistry of the first stars, giving scientists a clearer idea of what the Universe was like in its infancy. |
| Hubble looks in on a nursery for unruly young stars Posted: 09 Feb 2014 04:59 PM PST A striking new image, captured by the NASA/ESA Hubble Space Telescope, reveals a star in the process of forming within the Chameleon cloud. This young star is throwing off narrow streams of gas from its poles -- creating this ethereal object known as HH 909A. These speedy outflows collide with the slower surrounding gas, lighting up the region. |
| Posted: 09 Feb 2014 02:31 PM PST NASA's Spitzer and Hubble Space Telescopes have spotted what might be one of the most distant galaxies known, harkening back to a time when our universe was only about 650 million years old (our universe is 13.8 billion years old). The galaxy, known as Abell2744 Y1, is about 30 times smaller than our Milky Way galaxy and is producing about 10 times more stars, as is typical for galaxies in our young universe. |
