Solar Activity Impacts Climate More During “Cool Periods”

Medicine & Technology New research published in the Journal Geology suggests there is a link between the activity of the sun and sea temperatures and its effects are more significant when the Earth is cooler. The sun is already known to play a part in variations of our weather but this is the first time that scientists have observed that solar activity also affects sea surface temperatures.

Could More Dwarf Planets Lie Beyond Pluto

According to calculations by scientists at the Complutense University of Madrid and the University of Cambridge, not one, but at least two dwarf planets must exist beyond Pluto in order to explain the orbital behavior of extreme trans-Neptunian objects.

NuSTAR Telescope Helps NASA Find Nanoflares on the Sun

With a new day in science comes a new study of the sun. No, we’re not talking about a new telescope or a new division under the international space agencies, but rather a reallocation of a science used in other parts of space. Turning their sights from far off black holes, with a closer subject in mind, NASA’s Solar Dynamics Observatory (SDO) is repositioning their NuSTAR (Nuclear Spectroscopic Telescope Array) towards our very own local star to produce the most sensitive measurements of high-energy solar x-rays to date.

Binary Stars Merge and Beat Supermassive Black Hole

Nearly every Sci-Fi film about deep space has warned about the perils of coming up against a black hole. And if there’s anything we’ve learned, or that astronomy has taught us, it’s that these supermassive vortex’s have quite a strong pull—something most planets and stars cannot bare to go through. But as it so happens, it turns out that cosmic coupling may be one solution for solar systems looking to avoid certain death.

From California to New York—Where To Catch A Glimpse of an Eclipsing Sky

For those of you in the states enjoying a welcomed break from the summer sun, today you may just get more than you bargained for. As the moon passes this afternoon across the northern hemisphere, the usually invisible transition will make its mark in daylight as it eclipses part of the sun. And so long as the clouds stay clear of the view, you may just have an interesting afternoon show to look out for.

Partial Eclipse Captures Daylight—Seen Across the Northern Sky (CA, NV, NY, OR, FL)

Today marks a rare occasion, one where alignment makes a spectacle in the sky. While you can expect the autumn day to have cool weather and an added air of sunshine, you can also expect quite a surprise when part of the sun disappears in the mid-afternoon shade. It’s a rare occurrence that you won’t catch for another 3 years at the soonest, but the partial solar eclipse won’t be enjoyed by everyone. Mostly it’ll be a show for the northern United States.
Manned Missions to Mars Threatened by Cosmic Rays

Future Mars Missions Threatened by Cosmic Radiation

Young would-be space explorers received some bad news this week. Due to the Sun entering in to a phase of relatively low solar activity, cosmic radiation is projected to increase to such levels that any prolonged manned space expedition would prove harmful and even deadly to the astronauts involved.
Partial Solar Eclipse

Taking A Bite Out of Sunlight—US Expects A Partial Solar Eclipse

Predicted to occur this Thursday, Oct. 23, the off-center new moon will pass in front of the sun creating a partial solar eclipse seen across the United States. Though the predicted visibility will range anywhere from twelve to seventy percent of clarity, researchers at NASA expect that the event will be widely visible across the entire continental US.
