 The Hubble Space Telescope has been improved to measure distances up to 10,000 light-years away. Astronomers have developed a new technique called spatial scanning to increase the telescope's ability to gauge distances. This method uses trigonometry to calculate distances and is expected to yield new insights into dark energy, a mysterious component of space.
