Until about a century ago, astronomers thought that our galaxy is the only one in the entire Universe. But the American astronomer Edwin Hubble changed all that in the ’20s, and until now we’ve learned tons of new things about our Cosmos. It is certain that there are trillions of other galaxies out there, and this is the conclusion if we only take into account the observable Universe. The Universe can be even a million times bigger than what humanity has been able to see with its telescopes.
The Hubble Telescope has already captured wonderful insights of many other galaxies, and now one more is added to the list: NGC 3175.
The galaxy is 54 million light-years away
NGC 3175, or also known as ESO 436-3, LEDA 29892 and UGCA 207, is an edge-on spiral galaxy located very far away in the constellation of Antlia. And it looks beautiful, as you can see for yourself in the image below:
If by some reason you want to admire the galaxy up-close in all its glory, you need to travel a staggering distance: about 54 million light-years. And, of course, you need to find a way to travel that tremendous distance way faster than the speed of light. Einstein said that it’s impossible to surpass the speed of light, but who knows, he also made some blunders.
Discovered about two centuries ago
One amazing fact about the NGC 3175 galaxy is that it was discovered by the English astronomer John Herschel in 1835. In that time, astronomers didn’t know that NGC 3175 is actually a galaxy, but instead they called it a ‘nebula’.
One Hubble astronomer explained to us:
Galaxy groups are some of the most common galactic gatherings in the Cosmos, and they comprise 50 or so galaxies all bound together by gravity,
A galaxy group to which NGC 3175 belongs is a nearby analogue for the Local Group, which contains our Milky Way Galaxy and around 50 others — a mix of spiral, irregular, and dwarf galaxies.”
Let’s just hope that one day humanity will be able to know exactly what other beauties do the stars and planets of NGC 3175 are harboring.
