Japan’s Himawari weather satellites, designed to watch Earth, have quietly delivered a decade of infrared snapshots of Venus. By stitching 437 images together, scientists tracked daily thermal ...

The outlook is promising for future long-term monitoring of planets across multiple wavelengths. Infrared imaging data from Japan’s Himawari-8 and Himawari-9 meteorological satellites have been successfully applied to track changes in the temperature of Venus’ cloud tops over time.

Only one of the known Venus co-orbital asteroids follows a nearly circular orbit; the others move on more elongated paths that sometimes bring them closer to Earth, making them easier to detect. However, Carruba's team believes this pattern may reflect observational bias, not the actual makeup of the population.

In an unexpected discovery, two weather satellites designed to monitor Earth’s atmosphere have ended up capturing valuable information about Venus. Weather Satellites Meant for Earth Record Stunning Venus Data Japan’s Himawari-8 and Himawari-9 satellites,

The transit of Venus of June 5-6, 2012 will offer the rare sight of Venus as a small dot marching slowly across the sun's face. ... Earth, Venus and the sun will be in a straight line.

Japan's Himawari-8 and Himawari-9 satellites, designed to study weather here on Earth, have also been quietly collecting valuable data on Venus for nearly a decade, scientists recently discovered.
