What’s up in the June night skies? Find out how you can see Jupiter at its biggest and brightest, while Mercury and Mars appear ultra-close + how you can observe the Moon’s tilted orbit. Watch & find out more on the latest episode of NASA’s What’s Up:
Although oxygen is common throughout the cosmos, most of it isn’t in the form that we as humans need to breathe – molecular oxygen, or O2. Now, researchers at Caltech claim to have created a reactor that can turn carbon dioxide into molecular oxygen, which could help us fight climate change here on Earth or generate oxygen for life in space.
Somewhere in the outer reaches of the Solar System, beyond the orbit of Neptune, something wonky is happening. A few objects are orbiting differently from everything else, and we don’t know why.
A popular hypothesis is that an unseen object called Planet Nine could be messing with these orbits; astronomers are avidly searching for this planet. But earlier this year physicists came up with an alternative explanation they think is more plausible.
Instead of one big object, the orbital wobblies could be caused by the combined gravitational force of a number of smaller Kuiper Belt or trans-Neptunian objects (TNOs). That’s according to astrophysicists Antranik Sefilian of the University of Cambridge in the UK and Jihad Touma of the American University of Beirut in Lebanon.
