NASA Voyager 2 could be nearing interstellar space

NASA's Voyager 2 probe, currently on a journey toward interstellar space, has detected an increase in cosmic rays that originate outside our solar system. Launched in 1977, Voyager 2 is a little less than 11 billion miles ...

Suddenly, the sun is eerily quiet: Where did the sunspots go?

The sun has gone quiet. Almost too quiet. A few weeks ago it was teeming with sunspots, as you would expect since we are supposed to be in the middle of solar maximum-the time in the sun's 11-year cycle when it is the most ...

NASA study finds solar storms could spark soils at moon's poles

Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce "sparks" that could vaporize and melt the soil, perhaps as much as meteoroid impacts, according ...

New Horizons fills gap in space environment observations

When NASA's New Horizons sped past Pluto on July 14, 2015, it took the best-ever pictures of the rocky world s surface, giving us new insight into its geology, composition and atmosphere. These stunning images are the most ...

Scientists observe largest solar flare in 12 years

The sun's largest solar flare in more than 12 years – and the eighth largest since modern records began in 1996 – has been captured in high detail by a team of researchers from the University of Sheffield and Queen's ...

Sun may determine lifespan at birth, study finds

Could the Sun be your lucky—or unlucky—star? In an unusual study published Wednesday, Norwegian scientists said people born during periods of solar calm may live longer, as much as five years on average, than those who ...

Solar storm heads Earth's way after double sun blasts

Two big explosions on the surface of the sun will cause a moderate to strong geomagnetic storm on Earth in the coming days, possibly disrupting radio and satellite communications, scientists said Thursday.

Voyager 1 revealing regularity of interstellar shock waves

(Phys.org)—The "tsunami wave" that NASA's Voyager 1 spacecraft began experiencing earlier this year is still propagating outward, according to new results. It is the longest-lasting shock wave that researchers have seen ...
