Dusty Snow on Mars Could be Melting Just Below the Surface

Dust on Mars gets everywhere – including on top of ice deposited during one of Mars’ previous ice ages.  Just how that dust affects the ice is still up for some debate. Adding to that debate, a recent paper by researchers at Arizona State University and the University of Washington has laid out a map between the dust content of a glacier and the brightness of its ice.

A rocket-shaped stack of cheese and crackers could now launch your kid on a real-life space adventure.

Brown Dwarfs are Probably Much More Common in the Milky Way Than Previously Believed

Brown dwarfs are strange things. They are in the middle ground between planets and stars. A star is defined as an object massive enough for helium to fuse into hydrogen into its core, while a planet is too small for core fusion to occur. It seems a simple distinction until you learn about fusion. Anything with a mass below about 13 Jupiters is too small for fusion to occur, and is thus a planet. If your mass is about about 80 Jupiters, then you can fuse helium and are therefore a star. But if your mass is between 13 and 80 Jupiters, things get interesting. You can’t fuse hydrogen to shine brightly, but you can fuse lithium into other elements. This is known as lithium burning. It doesn’t provide lots of energy, but it is technically nuclear fusion.

A quarter of sunlike stars eat their own planets, according to new research

How rare is our solar system? In the 30 years or so since planets were first discovered orbiting stars other than our sun, we have found that planetary systems are common in the galaxy.

China Wants to Build a Spaceship That’s Kilometers Long

It’s no secret that China has become a major contender when it comes to spaceflight. In the past twenty years, the China National Space Agency (CNSA) has accomplished some historic firsts. This includes sending astronauts to space, deploying three space stations (as part of the Tiangong program), developing heavy launch vehicles (like the Long March 5), and sending robotic explorers to the far side of the Moon and Mars.
