Mars is the 4th planet from Sun, and the place that holds our imagination because of the possibility that there might be life there. There are some similarities to Earth, like its day length, solid ground and polar caps, but there are many differences as well, like its much smaller size, mass and gravity. And don’t forget about the extremely cold temperatures. Let’s learn about Mars compared to Earth.
There is more to the Earth than what we can see on the surface. In fact, if you were able to hold the Earth in your hand and slice it in half, you’d see that it has multiple layers. But of course, the interior of our world continues to hold some mysteries for us. Even as we intrepidly explore other worlds and deploy satellites into orbit, the inner recesses of our planet remains off limit from us.
In 1610, Galileo Galilei looked up at the night sky through a telescope of his own design. Spotting Jupiter, he noted the presence of several “luminous objects” surrounding it, which he initially took for stars. In time, he would notice that these “stars” were orbiting the planet, and realized that they were in fact Jupiter’s […]
Our Sun regularly pelts the Earth with all kinds of radiation and charged particles. Just how bad can these solar storms get? In today’s episode, we’re going to remind you how looking outside of the snow globe can inspire your next existential crisis. You guys remember the Sun right? Look how happy that little fella […]
KENNEDY SPACE CENTER, FL – NASA’s constellation of state-of-the-art magnetospheric science satellites successfully rocketed to orbit late Thursday night, March 12, during a spectacular nighttime launch on a mission to unravel the mysteries of the process known as magnetic reconnection. The $1.1 Billion Magnetospheric Multiscale (MMS) mission is comprised of four formation flying satellites blasted […]
NASA’s first mission dedicated to study the process in nature known as magnetic reconnection undergoing final preparation for launch from Cape Canaveral, Florida in just under two weeks time. The Magnetospheric Multiscale (MMS) mission is comprised of a quartet of identically instrumented observatories aimed at providing the first three-dimensional views of a fundamental process in […]
The mystery of the northern lights – aurora – spans time beyond history and to cultures of both the southern and northern hemispheres. The mystery involves the lights, fantastic patterns and mystical changes. Ancient men and women stood huddled under them wondering what it meant. Was it messages from the gods, the spirits of loved […]
It’s a well-known fact that Earth’s ozone layer protects us from a great deal of the Sun’s ultra-violet radiation. Were it not for this protective barrier around our planet, chances are our surface would be similar to the rugged and lifeless landscape we observe on Mars. Beyond this barrier lies another – a series of […]
(Scroll down for latest update) Auroras showed up as forecast last night beginning around nightfall and lasting until about 1 a.m. CDT this morning. Then the action stopped. At peak, the Kp index dinged the bell at “5” (minor geogmagnetic storm) for about 6 hours as the incoming shock from the arrival of the solar blast rattled Earth’s magnetosphere. It […]
