To reduce the emissions fueling climate change and develop more efficient ways of generating energy, while focusing on the bottom line, governments and private institutions all over the world have been turning to renewable energy. And while solar and wind energy advance and become more widely accepted, scientists continue to explore the possibility of stabilizing nuclear fusion as a truly renewable energy source that far outperforms current options.
But what if there’s an even better source of energy that’s also potentially less volatile than nuclear fusion? This possibility is what researchers from Tel Aviv University and the University of Chicago proposed in a new study published in the journal Nature.

The earliest mammals were night creatures which only emerged from the cover of darkness after the demise of the daytime-dominating dinosaurs, according to new research.
This would explain why relatively few mammals follow a daytime-active – or “diurnal”– lifestyle today, and why most that do still have eyes and ears more suitable for living by night.

Travelling to other solar systems is not as far away as you might think...
Every day, our spacecraft and people are exploring the solar system. Both the public and the private sectors are contributing to the quest. For example, here are ten things happening just this week:
1. We deliver.
The commercial space company Orbital ATK is targeting Saturday, Nov. 11 for the launch of its Cygnus spacecraft on an Antares rocket from Wallops Flight Facility in Wallops Island, Virginia. Cygnus is launching on a resupply mission to the International Space Station, carrying cargo and scientific experiments to the six people currently living on the microgravity laboratory.
2. See for yourself.
Social media users are invited to register to attend another launch in person, this one of a SpaceX Falcon 9 rocket carrying the Dragon spacecraft from Cape Canaveral Air Force Station in Florida. This launch, currently targeted for no earlier than December, will be the next commercial cargo resupply mission to the International Space Station. The deadline to apply is Nov. 7. Apply HERE.
3. Who doesn’t like to gaze at the Moon?
Our Lunar Reconnaissance Orbiter (LRO) sure does—and from very close range. This robotic spacecraft has been orbiting Earth’s companion since 2009, returning views of the lunar surface that are so sharp they show the footpaths made by Apollo astronauts. Learn more about LRO and the entire history of lunar exploration at NASA’s newly-updated, expanded Moon site: moon.nasa.gov
4. Meanwhile at Mars…
Another sharp-eyed robotic spacecraft has just delivered a fresh batch of equally detailed images. Our Mars Reconnaissance Orbiter (MRO) surveys the Red Planet’s surface daily, and you can see the very latest pictures of those exotic landscapes HERE. We currently operate five—count ‘em, five—active missions at Mars, with another (the InSight lander) launching next year. Track them all at: mars.nasa.gov.
5. Always curious.
One of those missions is the Curiosity rover. It’s currently climbing a rocky highland dubbed Vera Rubin Ridge, turning its full array of instruments on the intriguing geology there. Using those instruments, Curiosity can see things you and I can’t.
6. A new Dawn.
Our voyage to the asteroid belt has a new lease on life. The Dawn spacecraft recently received a mission extension to continue exploring the dwarf planet Ceres. This is exciting because minerals containing water are widespread on Ceres, suggesting it may have had a global ocean in the past. What became of that ocean? Could Ceres still have liquid today? Ongoing studies from Dawn could shed light on these questions.
7. There are eyes everywhere.
When our Mars Pathfinder touched down in 1997, it had five cameras: two on a mast that popped up from the lander, and three on the rover, Sojourner. Since then, photo sensors that were improved by the space program have shrunk in size, increased in quality and are now carried in every cellphone. That same evolution has returned to space. Our Mars 2020 mission will have more “eyes” than any rover before it: a grand total of 23, to create sweeping panoramas, reveal obstacles, study the atmosphere, and assist science instruments.
8. Voyage to a hidden ocean.
One of the most intriguing destinations in the solar system is Jupiter’s moon Europa, which hides a global ocean of liquid water beneath its icy shell. Our Europa Clipper mission sets sail in the 2020s to take a closer look than we’ve ever had before. You can explore Europa, too: europa.nasa.gov
9. Flight of the mockingbird.
On Nov. 10, the main belt asteroid 19482 Harperlee, named for the legendary author of To Kill a Mockingbird, makes its closest approach to Earth during the asteroid’s orbit around the Sun. Details HERE. Learn more about asteroids HERE. Meanwhile, our OSIRIS-REx mission is now cruising toward another tiny, rocky world called Bennu.
10. What else is up this month?
For sky watchers, there will be a pre-dawn pairing of Jupiter and Venus, the Moon will shine near some star clusters, and there will be meteor activity all month long. Catch our monthly video blog for stargazers HERE.

Today is the birthday of the renowned theoretical physicist Stephen Hawking. Doctors grimly estimated that he wouldn't make it past his twenties, and today he turns 76 - and still one of the sharpest minds in the world. Happy birthday Stephen!
Atlantic hurricane season begins today.
People in other parts of the world call these storms typhoons or cyclones, but they are all the same thing: a rotating storm that forms in the tropics (that’s near the equator) and has winds of at least 74 miles per hour (119 kilometers per hour). “Hurricane” comes from Hurican, the name of an evil god for ancient peoples in the Caribbean. They took the name from Hurakan, the name the ancient Maya of Mexico gave to their god of wind and storm. For people in the tropics, these storms have always been a part of life.
