(Reuters) – A skydiving Google executive is safely back on Earth after jumping out of a giant balloon floating in the stratosphere more than 25 miles (40 km) above New Mexico, a feat that broke the sound barrier and shattered a world altitude record.
There was already a high probability that active region (AR) 2192 was going to erupt with a powerful solar flare, so it came as little surprise when, yesterday, the huge sunspot fired a powerful X-class flare right at Earth. And … Continue reading →
People with a rare disorder called anhidrosis cannot produce sweat, and now a new study finds that the condition may be caused by a mutation in a single gene.
Russia on Sunday is set to turn back its clocks to winter time permanently in a move backed by President Vladimir Putin, reversing a three-year experiment with non-stop summer time that proved highly unpopular.
Google’s Alan Eustace fell from an altitude of more than 135,000 feet, plummeting for some 15 minutes. The jump broke the record of 127,852 feet that Felix Baumgartner set in 2012.

Concluding a busy five week mission, the SpaceX Dragon CRS-4 commercial cargo ship departed the International Space Station (ISS) this morning, Oct. 25, after delivering a slew of some 2.5 tons of ground breaking science experiments and supplies that also inaugurated a new era in Earth science at the massive orbiting outpost.
Dragon was released from the snares of the station’s robotic arm at 9: 57 a.m. EDT while soaring some (…)

Several Mars-based NASA spacecraft had prime viewing positions for comet Siding Spring’s October 19 close flyby of the Red Planet. Early images included a composite photo from NASA’s Hubble Space Telescope that combined shots of Mars, the comet, and a star background to illustrate Siding Spring’s distance from Mars at closest approach.
You could fit all the planets within the average distance to the Moon.
I ran into this intriguing infographic over on Reddit that claimed that you could fit all the planets of the Solar System within the average distance between the Earth and the Moon.
I’d honestly never heard this stat before, and it’s pretty amazing how well they tightly fit together.
But I thought it would be a good idea to doublecheck the math, just to be absolutely certain. I pulled my numbers from NASA’s Solar System Fact Sheets, and they’re a little different from the original infographic, but close enough that the comparison is still valid.
The average distance from the Earth to the Moon is 384,400 km. And check it out, that leaves us with 4,392 km to spare.
So what could we do with the rest of that distance? Well, we could obviously fit Pluto into that slot. It’s around 2,300 km across. Which leaves us about 2,092 km to play with. We could fit one more dwarf planet in there (not Eris though, too big).
