Virgo Quasar (3C 273)
- Distance From Earth: 2.9 Billion Lightyears
- Number Of Stars: Unknown
While some have called it the Virgo Quasar, astronomers and other scientists simply refer to it as 3C 273. This happens to be the first-ever quasar discovered. The discovery initially took place in the 1950s but would not be confirmed until the 1960s. A quasar is pretty interesting too. They are simply galactic nuclei powered by a black hole. It seems odd that we’d see anything near a black hole, but we did see 3C 273. It’s one of the brightest quasars ever discovered. Due to having a galactic nucleus, it is at least possible alien worlds are within it. However, the presence of a black hole may throw off timelines somewhat.
If alien worlds were looking at Earth from here, they’d see a very young planet. The first known continent formed around this time. That was not Pangea, as that was a supercontinent. We’re saying that this timeframe saw the first landmass continent, period. It is still debated what else took place at this time. Many scientists believe that oxygenic photosynthesis took place at this point. It’s interesting to note that photosynthetic life was retinal-based rather than chlorophyll-based. Thus, the Earth likely looked purple rather than blue and green during this time period.
