NASA's STEREO satellite captured the first images ever of a collision between a solar "hurricane", called a coronal mass ejection (CME), and a comet. The collision caused the complete detachment of the comet's plasma tail. Scientists...

Dean Pesnell, the SDO Project Scientist, explains how the Helioseismic and Magnetic Imager (HMI) instrument will allow us to see activity inside the sun and even on the other side of the sun.

NASA satellites use very sensitive devices called magnetometers to measure the magnetic fields of planets. Like very sensitive compasses, these devices can measure both direction and strength of planetary magnetic fields. Learn more...

NASA scientists answer some common questions about the sun, space weather, and how they affect the Earth. This is a two-part series.



Part One

Alejandro Arambula is an aerospace engineering student at M.I.T. and a summer intern in the Propulsion Lab. This summer he is working with his mentor Khary Parker in building a test assembly for a specific zone of the propulsion...

Five years after NASA’s MAVEN spacecraft entered into orbit around Mars, data from the mission has led to the creation of a map of electric current systems in the Martian atmosphere....

Senior Project Scientist Tom Moore outlines the three instrument suites onboard the four MMS spacecraft.



On March 12, 2015, NASA plans to launch the Magnetospheric Multiscale, or MMS, mission. MMS consists of four...

This video is answering the question of why do opposite poles attract.

Scientists are starting to understand how solar storms use currents in Earth’s magnetic shield to land some punches.

Hard Disk Drives (HDDs), which store data on rotating magnetic disks, have been the go-to mass storage media for decades. A good tech understands how this venerable media works and understands magnetic media’s unique needs. This clip is...

Writing in the Geophysical Research Letters, NASA says a review of Voyager 2’s old data from 1986 showed that Uranus vented a giant blob of gas into space. <br/>

Researchers from China's Hefei Institutes of Physical Science reported its fusion reactor reached 100 million degrees Celsius, over six times the temperature of the sun's core.

New research from the University of Miami and Norway’s Institute of Marine Research has found that the European eel at a certain stage of development use an internal magnetic compass to remember the magnetic direction of tidal waves as...

The new train uses electromagnets to hover and move, and it can easily beat a passenger jet on a thousand-kilometer route.

Ongoing geomagnetic storms have led to sightings of the Northern Lights across North America this week, the result of a coronal mass ejection from the Sun that occurred on Sunday, sending a stream of charged particles toward Earth.

China says it has built an artificial moon that can make frogs and pretty much anything else float in the air.

Researchers theorize that, if nothing is done about the millions of pieces of space junk orbiting Earth, our planet will develop rings made of junk.

This video is a lecture on solenoids and the magnetic field that forms around them. The lecturer explains the concept of magnetic fields and how they can form around conducting wires. They demonstrate how the direction of the current...

This video is a lecture on magnetic fields. The speaker explains what magnetic fields are, how they look in the regions around magnets, and how to plot them on diagrams. The video also covers how the magnetic fields of two magnets in...

Cookie the chef is a multitalented guy. He’s an amazing barista, too! He really takes filter coffee to the next level. Meanwhile, First Mate Phil needs a hand, or a hook, with fixing the ship’s hull. This lesson will explore separation...

This video explores five fun facts about magnets.

We only interact with the very surface of the Earth, called the crust. So what else is down there? What is the composition of the Earth? How many layers are there, and how do they differ? What is the mantle, and how does it convect? What...

It demonstrates the basic properties of magnets such as attraction, repulsion and direction using simple activities.

Magnets can be found in many objects that we use everyday. Not only are they located in man-made objects, but magnetic materials can be found in nature as well. In fact, the mineral, magnetite, was found to have magnetic properties long...
