Say hello to MK 2, our solar system’s newest moon

Say hello to MK 2, our solar system’s newest moon Some in the scientific community are still trying to do an exhaustive search of our own solar system, however, especially in the little-known area beyond Neptune.This week, NASA announced a new discovery in that effort to catalog local wanderers: a new moon they’ve nicknamed MK 2.

Red Dwarf: Planet beyond Neptune confirmed as third-largest in the solar system

Red Dwarf: Planet beyond Neptune confirmed as third-largest in the solar system Astronomers have confirmed that the dwarf planet 2007 OR10 is one of the largest objects beyond the orbit of Neptune that we’re currently aware of.By using these two sources, the researchers were able to confirm that 2007 OR10 is larger than we first thought, with a much slower rotation period.

Pluto’s smooth surface is probably a sea of slow-flowing nitrogen ice

Pluto’s smooth surface is probably a sea of slow-flowing nitrogen ice A pair of studies have just been published that could offer an explanation — convecting nitrogen ice.On Pluto, it’s well below the freezing point of nitrogen, so you’d naturally expect to find some nitrogen ice.

Pluto may still have a subsurface liquid ocean

Not only is the topography unique and the atmosphere cloudy, but Pluto may even have a liquid ocean.A new analysis of Pluto suggests that the subsurface ocean that gave rise to some of its geological anomalies could still be sloshing around down there.

Unexpected, mysterious x-rays found emanating from Pluto

Unexpected, mysterious x-rays found emanating from Pluto The image above may look like a blue blob, but it’s actually the dwarf planet Pluto.If this is confirmed, Pluto would be the most distant x-ray source in the solar system.

This week in space: lots of things about planets we don't live on

This week in space: lots of things about planets we don't live on There are three kinds of space weather: photons, plasma and protons.“These protons may be the biggest challenge of getting humans to Mars and back healthy,” Rodney Viereck, a physicist with NOAA’s Space Weather Prediction Center, told NPR’s Morning Edition.
