how jupiter may have moved it, moved it from the outer reaches of the solar system

Considering what we know about planetary formation, Jupiter shouldn’t have been able to grow as massive in its current orbit. But a new simulation shows it could’ve been born much, much further away.

why nasa may be trying to quietly put the sls out of its misery

NASA appears to be sick and tired of having to wait until the mid-2020s to return to the Moon on a future rocket that will be inferior to the private ones already flying, and easily lapped by ones currently being built.

how can we save earth from a doomsday asteroid? with robotic space jujitsu!

It may be tempting to use our nuclear warheads to save the planet from rogue space rocks instead of pointing them at each other, it would be a waste of perfectly good nukes.

why we need to learn more about super-earths

Super-Earths are often thought of as just bigger version of our own planet on steroids. But these worlds offer us amazing insights into everything from plate tectonics to planetary formation and classification.

there may not be dark matter or energy, just gravity. we just don’t know how.

Theoretical physicists seem ready to move on from looking at dark matter as unknown particles we’ve yet to discover, and consider it a side-effect of gravity at cosmic scales.

was mars one the fyre festival of space startups?

Mars One was an impossible dream. No, literally. As in not possible and could never happen. Now the company is bankrupt and its mission plans abandoned, which is really for the best.

how we know the milky way is warped and twisted, and how it got that way

If you imagine galaxies as tranquil clouds of gas and dust, lit up by billions of pinpoints of light, a 3D map of the Milky Way and the details behind it will show you otherwise.
