I think 'The Hitchhiker's Guide to the Galaxy' is really well - known. It has a cult following. There are these really zany aliens like the Vogons. Then there's 'War of the Worlds'.

One of the best aliens is the Martians from H.G. Wells' 'The War of the Worlds'. They are highly intelligent and their advanced technology makes them a formidable force. Their tripods are iconic symbols of their invasion.
Intelligence is a common trait among the top aliens. Take the Time Lords from 'Doctor Who' books. They possess vast knowledge and the ability to manipulate time and space. Their advanced civilization and complex technology set them apart as truly remarkable aliens.
Definitely 'The Andromeda Strain' by Michael Crichton. It has an alien - like microbe from outer space that causes a major crisis on Earth. It's a page - turner. 'Rendezvous with Rama' by Arthur C. Clarke is another great one. The discovery of the huge alien spacecraft Rama is fascinating. 'The Left Hand of Darkness' by Ursula K. Le Guin has a unique alien race, the Gethenians, whose gender - less nature challenges human concepts.
Well, 'A Fire Upon the Deep' by Vernor Vinge also has interesting alien concepts in a fictional setting. It's set in a universe where different regions have different laws of physics. There are various alien species with unique cultures and abilities. The book is complex and full of mind - bending ideas about alien intelligence and inter - species relations.
Well, if you're just starting out, 'Rendezvous with Rama' is a great book to pick up. It's a fascinating exploration of an alien object. The story is well - paced and not overly complicated. 'Hyperion' is another one. Although it has a lot going on, the parts related to the Shrike, the alien - like entity, are really captivating. And 'Childhood's End' is also good.
