More than 90 years after California’s last wolf was killed, a pack has been observed near Mt. Shasta. Are the mountain’s glaciers a reason the wolves chose this location?
In both the evening and morning sky, try watching for Earth’s shadow. Earth’s shadow is a deep blue-grey, darker than the twilight sky. The pink band above the shadow – in the east after sunset, or west before dawn – is called the Belt of Venus.
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.
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.
Our efficient killing technologies have given rise to the human super predator. Our impacts are as extreme as our behavior, says study.
If so, where are likely to find it and could we ever get to it? And would we be able to drink it? A planetary geologist discusses these issues.
Check out this wonderful animation from Larry Koehn of the website shadowandsubstance.com. It shows Venus in the morning sky 45 minutes before sunrise from August 2015 through March 2016.
Every year, during the last week of August, a first hint of the changing of the seasons can be seen in the predawn sky: Orion the Hunter and Sirius the Dog Star. Orion the Hunter rises before dawn at this time of year, recognizable for the short straight line of three stars that make up Orion’s Belt. And the sky’s brightest star Sirius – sometimes called the Dog Star – follows Orion into the sky at or close to dawn.
A University of Washington biologist has encountered what he considers one of the world’s rarest animals. It’s a species of nautilus called Allonautilus scrobiculatus. Peter Ward and a colleague originally discovered this nautilus species in 1984 off Ndrova Island in Papua New Guinea. Then no one saw this creature again for over 30 years.
