The Juno spacecraft takes batches of photos about every 53 days as it orbits Jupiter. NASA has shared brand new photos of Jupiter taken by the Juno spacecraft, showing the gas giant’s blue-tinged skies.

  NASA tests small nuclear reactor that could power a habitat on Mars © Provided by Engadget Everyone from Elon Musk to Donald Trump wants to send a manned mission to Mars in the not too distant future, but there are quite a few problems that need to be solved before we can achieve that goal. A major one is the issue of energy. Long-term stays on Mars, or anywhere else for that matter, will require lots of energy, as will the trip back to Earth. However, loading a rocket up with all of the necessary fuel won't work -- we would need too much. So a way to create fuel on the go is a must and researchers at NASA, Los Alamos National Laboratory and the Department of Energy announced today that they've conducted successful tests of a system that can do just that.

Scientists Have Discovered Massive Ice Sheets on Mars

  Scientists Have Discovered Massive Ice Sheets on Mars Massive ice sheets have been discovered on Mars that could potentially be a resource for astronauts to harness for exploration of the planet. According to a report published on Friday in the journal Science, scientists examined eight areas on Mars where erosion has occurred. Researchers discovered massive ice sheets in the planet’s mid-latitudes that are believed to extend up to 100 meters deep and contain distinguishable layers that, “could preserve a record of Mars’ past climate,” the report says. “They might even be a useful source of water for future human exploration of the red planet.

Kilopower is a small nuclear reactor that can generate a reliable power supply. Versions range from 1 kilowatt -- enough to power a basic toaster -- to ten kilowatts and Kilopower project researchers said in a Space.com article that around four or five of the latter would be needed to power a habitat on Mars. "Kilopower's compact size and robustness allows us to deliver multiple units on a single lander to the surface that provides tens of kilowatts of power," Steve Jurczyk, associate administrator of NASA's Space Technology Mission Directorate, said during a press conference today.

Testing of the Kilopower system has gone smoothly so far and in March, the team plans to conduct a full-power test. To hear more about how Kilopower works, check out the video below.

‘Dwarfquakes’ Reveal the Future of Our Universe .
Dying stars were an enigma—until an astronomer measured seismic shifts on them, giving us clues about the sun’s future and the expansion rate of the universe.Made of pure carbon and oxygen, with only a thin haze of other atoms acting as its atmosphere, white dwarfs certainly aren’t like anything we can make in a lab on Earth. But Giammichele used seismology to measure “dwarfquakes” to not only understand the internal structure of these white dwarfs but also the future expansion rate of our universe.
