NASA’s Terra satellite just released this August 29 image of Hurricanes Kilo, Ignacio, and Jimena, all Category Four Hurricanes. According to the Weather Channel:
This is the first recorded occurrence of three Category 4 hurricanes in the central and eastern Pacific basins at the same time. In addition, it’s also the first time with three major hurricanes (Category 3 or stronger) in those basins simultaneously, according to hurricane specialist Eric Blake of the National Hurricane Center.
The moon’s apparent size in our sky depends on its distance from Earth. The supermoon of March 19, 2011 (right), compared to an average moon of December 20, 2010 (left). Image by Marco Langbroek of the Netherlands via Wikimedia Commons.
The moon reaches perigee – nearest point to Earth in its orbit – on August 30, 2015 at 15:24 UTC. This perigee comes less than one day after the moon reached the crest of its full phase on August 29 at 18:35 UTC.
Supermoon weekend! The full moon of August 29, 2015 will be the first of this year’s three full supermoons. It’s a full moon near perigee, or near its closest point to Earth for the month. Like it or not, modern skylore dictates that these sorts of moons are called supermoons.
The narrow F ring located just outside of the outer edge of the main rings. Two satellites sandwiching the F ring slightly above and to the left of the center of the image are the shepherd satellites Prometheus (inner orbit) and Pandora (outer orbit).
Scientists at Kobe University in Japan this week announced results of a study showing that Saturn’s F ring and its shepherd satellites are natural by-products of the final stage of formation of Saturn’s satellites. The F ring is the outermost of Saturn’s rings. It is perhaps the most active ring in our solar system, with features changing on a timescale of hours.
Sharpened, enlarged crop of the mountain 1 Ceres, acquired by the Dawn spacecraft on August 19, 2015. Dawn was 910 miles (1,470 km) from Ceres at the time. Image via NASA/JPL-Caltech/UCLA/MPS/DLR/IDA.
Enjoying the Dawn mission to dwarf planet Ceres? Welcome to HAMO (High Altitude Mapping Orbit). Dawn has now moved to within about 900 miles (1,500 km) from Ceres. This phase of the mission has just begun and promises to reveal even more about this little world. Here are some early images from that closer orbit.
