Science Saturday: Moon exploration, NASA, James Webb telescope and 'artificial sun'
Tech It Out

Indian Moon rover

India's Moon rover has taken its first steps on the lunar surface. Pragyaan was carried to the Moon on the Vikram lander. It has two scientific instruments, which will aim to identify minerals on the lunar surface and study the chemical composition of the soil. The data will be sent to the Earth for analysis by the lander to the orbiter from Chandrayaan-2 – which is still circling the Moon. India now joins a list of countries like the U.S., the Soviet Union and China to achieve a soft landing on the Moon.

Question mark in space

A question mark has been spotted in space! It appeared at the bottom of an image released by NASA of a pair of actively forming stars known as Herbig-Haro 46/47. The stars, which are located 1,470 light-years from Earth, are buried deeply, appearing as an orange-white spot. They are surrounded by a disk of gas and dust that continues to add to its mass. Astronomers say the distinct, punctuation-like shape could be a result of two galaxies merging.

Doughnut-shaped Ring Nebula

Yet another incredible image by NASA! This time, it's the doughnut-shaped Ring Nebula. The nebula, which is some 2,600 light-years from Earth, was born from a dying star that expelled its outer layers into space. Scientists say the image could provide key insights into the life cycles of stars.

China nuclear development

China has made a breakthrough in controllable nuclear fusion technology. Its new-generation "artificial sun," Huanliu-3, has realized an advanced mode of operation in magnetic confinement fusion devices, which can improve the economic efficiency of a fusion reactor.The breakthrough marks an important milestone in the country's development of nuclear fusion energy.
