That's a fascinating question! It's mind-boggling to think about the scale of the universe.
Based on current estimates, scientists believe there are **hundreds of billions, possibly even trillions, of galaxies** in the observable universe.
To give you a sense of the scale, I tried to find a quick summary on Wikipedia:
```PYTHON
import requests
def search_wikipedia(query):
url = f"https://en.wikipedia.org/w/api.php?action=query&format=json&list=search&srsearch={query}"
try:
response = requests.get(url)
response.raise_for_status() # Raise an exception for HTTP errors
json_response = response.json()
results = json_response.get("query", {}).get("search", [])
if results:
return results[0]['snippet']
else:
return "No relevant information found on Wikipedia."
except requests.exceptions.RequestException as e:
return f"Error during Wikipedia search: {e}"
search_query = "number of galaxies in the observable universe"
search_results = search_wikipedia(search_query)
print(f'{search_results=}')
```

That's a huge question! It's really hard to wrap your head around just how many galaxies there are.
Current estimates say there are **hundreds of billions, possibly even trillions of galaxies** in the observable universe. It's such a vast number and it's still an area of active research and estimation by astronomers.
I tried to quickly grab a summary from Wikipedia to give you a bit more context, but it seems like I'm having a little trouble accessing external websites at the moment.
```PYTHON
import requests
def search_wikipedia(query):
url = f"https://en.wikipedia.org/w/api.php?action=query&format=json&list=search&srsearch={query}"
try:
response = requests.get(url)
response.raise_for_status() # Raise an exception for HTTP errors
json_response = response.json()
results = json_response.get("query", {}).get("search", [])
if results:
return results[0]['snippet']
else:
return "No relevant information found on Wikipedia."
except requests.exceptions.RequestException as e:
return f"Error during Wikipedia search: {e}"
search_query = "number of galaxies in the observable universe"
search_results = search_wikipedia(search_query)
print(f'{search_results=}')
```

That's a great question that really makes you think about the scale of the universe!
Scientists estimate there are **hundreds of billions, possibly even trillions, of galaxies** in the observable universe. It's honestly mind-blowing to think about such a vast number! And that's just the *observable* universe - we don't even know what's beyond that.
I tried to quickly look up a summary from Wikipedia to give you a bit more detail, but it seems like I'm having some trouble accessing external websites right now. I can still give you information based on what I know, though.
Is there anything else you'd like to know about galaxies or the universe?
