A negative leap second could mean computer systems no longer run like clockwork. Credit: Florian Gaertner/Photothek/Getty The leap second could be scrapped as soon as October. The periodic adjustment to the world’s clocks, which has been done every few years since 1972, was already set to end by 2035. But authorities are considering an immediate
Explanation: A new telescope has been launched into space to study the universe. The Nancy Grace Roman Space Telescope (RST) has the same size main mirror as the Hubble Space Telescope (HST) but sees 100 times more sky during each snapshot. This is possible because when compared to HST, RST’s main mirror is more curved,
The field of view of the Nancy Grace Roman Space Telescope (artist’s illustration) will be roughly 100 times bigger than that of the Hubble Space Telescope.

Five antennas soak in the summer sun at the Deep Space Network’s Goldstone complex near Barstow, California, in August 2026. The recently completed Deep Space Station 23, a 34-meter (114-foot) beam-waveguide antenna, can be seen to the right of the frame in the foreground. The other three 34-meter antennas are, from left, DSS-26, DSS-25, and DSS-24.
From this vantage point, Roman will conduct an unprecedented survey of the universe. Its field of view is 100 times larger than Hubble’s and, according to NASA, it can survey the sky 1,000 times faster using its 300-megapixel infrared camera. Roman also has a Coronagraph system that can block and mask glare from stars, allowing
