问题 What is the new discovery?
Astronomers have announced the discovery of 32 new planets orbiting stars outside our solar system. The scientists told a conference in Portugal that the planets ranged from five times the mass of Earth up to five times that of Jupiter, the largest planet in the solar system.
    This latest discovery means more than 400 planets have been found outside our solar system, as yet there are none that appear able to sustain life, but the finding means that there are many more places in the universe where life could exist. Based on the new data, it’s believed as many as 40% of stars, like the sun, may have planets that orbit them. The findings were made using special equipment on a telescope at the European Southern Observatory in Chile.
