Hello Biniyam!
You don't need a telescope to look at the stars and identify constellations in the sky. You can also sometimes find planets like Venus, Jupiter, Saturn, and Mars using just your eyes. However, they will look just like bright stars in the sky without a telescope.
Christina mentioned star parties at planetariums as another way to enjoy astronomy if you don't have a telescope. If there isn't a planetarium near you, a lot of places are now having online astronomy events. The Van Allen Observatories at the University of Iowa has some upcoming virtual astronomy events on their Facebook page. If these don't work out for you, try checking out the web sites for astronomy departments at your local college or university, or nearby museums to see if they have any upcoming virtual events that you can participate in.
