-->Erythrulose is a naturally occurring four-carbon monosaccharide (tetrose sugar) detected for the first time in interstellar space.
-->The discovery was made near the centre of the Milky Way Galaxy using two radio telescopes in Spain.
-->Erythrulose is present in raspberries & is considered a prebiotic molecule relevant to the origin of life.
-->Sugars form the backbone of DNA and RNA (DNA contains deoxyribose; RNA contains ribose).
The finding supports the idea that complex organic molecules can form before stars & planets are fully formed.
Scientists suggest such sugars may have reached early Earth through comets and asteroids during the Late Heavy Bombardment (~4 billion years ago).
Asteroid Bennu has already been found to contain other sugars such as ribose and glucose, strengthening the theory of extraterrestrial delivery of life's building blocks.
The discovery strengthens the panspermia/astrochemical hypothesis that the basic ingredients of life may be widespread across the Universe.

Mongla Port is Bangladesh’s second-largest seaport, after Chattogram Port.
Mongla Port is located on the Bay of Bengal, near the Sundarbans.
Teesta River originates from the Tso Lhamo Lake (Sikkim) and flows through Sikkim, West Bengal and Bangladesh before joining the Jamuna (Brahmaputra).
Siliguri Corridor (Chicken’s Neck) is a narrow land corridor connecting mainland India with the North-East.
String of Pearls refers to China’s network of strategic ports and connectivity projects in the Indian Ocean Region (IOR).
Major String of Pearls ports: Gwadar (Pakistan), Hambantota (Sri Lanka), Kyaukpyu (Myanmar).
Belt and Road Initiative (BRI) is China’s global infrastructure and connectivity initiative launched in 2013.
SAGAR stands for Security and Growth for All in the Region- India’s maritime vision for the Indian Ocean Region.
