NASA uses the Hubble telescope to take amazing photographs of the Universe. In the latest picture taken by them, there are approximately 15000 galaxies spread across the infinity of space. It is definitely one of the biggest snapshots ever taken and it doesn’t just show tremendous distance, but time too.
Hubble Space Telescope
As we already said, Hubble is the telescope that NASA depends on to show us the mysteries of the Universe. This one photo, in particular, shows a lot of newborn stars as fresh blooming lights that decorate newly-formed galaxies.
In order to take this photo, NASA had to use Hubble’s ultraviolet camera. After this, they had to combine the resulting data with what was obtained after infrared and visible-light imaging. That’s how NASA managed to provide one of the most complete views on the Universe so far and it is something you couldn’t see with your naked eye.
What makes the difference?
NASA had to use all these types of cameras because the different galactic ages come with different types of light. Those that are most distant can only be seen on the infrared spectrum. Even if it started as ultraviolet, the expansion of the universe made it shift into infrared wavelengths.
The closer ones are able to be seen on a broader spectrum. Because Earth has an atmosphere, it acts as a filter for UV lights, so Hubble, from space, is necessary to get a clear picture. What resulted is a photograph that simply transcends time and space. NASA believes that the oldest stars in the picture are about 11 billion years old, only 3 billion years older than the Big Bang.
There are about 12000 freshly born stars. By comparing these different types of stars, astronomers can get a clearer picture of how the Universe was formed.
Laura grew up in a small town in northern Quebec. She studied chemistry in college, graduated, and married her husband one month later. They were then blessed with two baby boys within the first four years of marriage. Having babies gave their family a desire to return to the old paths – to nourish their family with traditional, homegrown foods; rid their home of toxic chemicals and petroleum products; and give their boys a chance to know a simple, sustainable way of life. They are currently building a homestead from scratch on two little acres in central Texas. There’s a lot to be done to become somewhat self-sufficient, but they are debt-free and get to spend their days living this simple, good life together with their five young children. Laura is an advocate for people with disabilities.
