The Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years. The last giant explosion took place in 1964, creating a new crater and covering an area of nearly 100 square kilometers with pyroclastic currents. But Shiveluch is actually breaking out at the moment, as it has been for over 20 years. Credit: Michael Krawczynski, Washington …

HELSINKI – French startup ThrustMe has performed the first on-track tests of an innovative iodine-powered electric propulsion system, demonstrating its ability to change the trajectory of a CubeSat. ThrustMes NPT30-I2-1U, the first electric propulsion system with iodine to be sent into space, is aboard the Beihangkongshi-1, a 12U CubeSat developed by Chinese commercial satellite manufacturer Spacety. A long March 6 …

Chewing bones is a favorite pastime of dogs. If a bone is much loved, the dog may even bury it. To humans, this behavior may seem strange, so why do dogs invest so much energy in burying their precious possessions? “The reason a dog buries something is to save it for later,” Teoti Anderson, a professional dog trainer and behavioral …

The seven TRAPPIST-1 planets have similar densities – the values do not differ by more than 3%. This makes the system quite different from our own. The difference in density between the TRAPPIST-1 planets and Earth and Venus may seem small – approx. 8% – but it is significant on a planetary scale. For example, one way to explain why …

NASA engineers are investigating the possibility of building a massive, kilometer-wide radio telescope on the moon that would dwarf everything we could build on Earth. The telescope, which would be constructed by robots, would take the form of a huge wire mesh antenna in a bowl shape that would hang suspended in a three-kilometer-wide crater on the other side of …

A stream of solar particles on their way from the sun to the earth can lead to technological problems. Solar storms can be harmful to satellite-based technology, as they can heat the Earth’s outer atmosphere, causing it to expand and make it more difficult for satellite signals to reach the Earth. Experts have stated that the solar wind’s top speeds …

A white dwarf is not your typical star. While main sequence stars like our Sun melt nuclear material in their nuclei to prevent it from collapsing under their own weight, white dwarfs use an effect known as quantum generation. The quantum nature of the electrons means that no two electrons can have the same quantum state. When you try to …
