A rare sighting of alien starships in Singapore.
Nah. Not really. These are actually the so-called Supertrees in Gardens by the Bay. Standing up to 50m tall, these vertical gardens are designed after real trees. Some will store solar energy, while others are used for circulation and venting purposes for the nearby conservatories.
They look most impressive in the early evening, when the skies are still blue and they light up in all their glory.
