NASA's Solar Dynamics Observatory has been keeping an eye on the sun for three years now, and in honor of that achievement, they have released this video of the changes our star has been through during the last three years. The video shows the increase in solar flares and coronal mass ejections (which send rivers of matter and radiation out into the solar system). The sun is reaching its 11-year solar maximum and the frequency of these events have been increasing.
It might not get you all the way to Cardassia Prime, but NASA hopes its newly launched solar-sail Sunjammer program will lead to a future where propellantless space craft are used for a multitude of functions beyond the Earth’s atmosphere.
“Once proven, solar sail technology could enable a host of versatile space missions, including flying an advanced space-weather warning system to more quickly and accurately alert satellite operators and utilities on Earth of geomagnetic storms caused by coronal mass ejections from the sun,” NASA said in a release.
CAPE CANAVERAL, Fla. — Earth-like worlds may be closer and more plentiful than anyone imagined.
Astronomers reported Wednesday that the nearest Earth-like planet may be just 13 light-years away — or some 77 trillion miles. That planet hasn’t been found yet, but should be there based on the team’s study of red dwarf stars.
Galactically speaking, that’s right next door.
The strongest solar flare in four years disrupted radio communications in southern China, according to the China Meteorological Administration.The solar flare, a huge explosion on the sun's surface caused by magnetic activity, affected transmissions in southern China on Tuesday, Xinhua news agency reported, quoting the CMA.The US space administration NASA confirmed that Monday's solar flare was the largest in four years, and the event sparked predictions of heightened activity on the northern hemisphere of the sun.
OTTAWA — Less than a third of the almost 300,000 members and supporters who signed up to choose the Liberal party’s next leader have so far registered to vote, prompting front-runner Justin Trudeau’s camp to complain about a host of technical glitches and request a one-week extension on registration.
With only three days left to register, just 89,000 had registered by Monday evening.
Members and supporters must register by Thursday in order to be entitled to vote.
