International Observe the Moon Night 2020 welcomed participants from all 7 continents, 103 countries, all 50 U. S. states, Guam, Puerto Rico, the U. S. Virgin Islands, and Washington, D.C. Hear from...

Every object, planet or person traveling through space has to contend with the Sun's damaging radiation -- and the Moon has the scars to prove it.



Research using data from NASA's ARTEMIS mission — short for...

By studying X-rays in deep space, we can learn about some of the most violent and extreme objects in the universe, such as black holes and the remains of stars that have exploded. NASA’s Imaging X-Ray Polarimetry Explorer, IXPE, will...

This version of SDO:Three Years in Three Minutes is extended and narrated by NASA's Goddard Space Flight Center heliophysicist Alex Young. He highlights many interesting aspects of the video and points out several of the...

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...

Our sun's adolescence was stormy—and new evidence shows that these tempests may have been just the key to seeding life as we know it on Earth.

This visualization shows the position of the sun's magnetic fields from January 1997 to December 2013. The field lines swarm with activity: The magenta lines show where the sun's overall field is negative and the green lines...

This video takes SDO images and applies additional processing to enhance the structures visible. While there is no scientific value to this processing, it does result in a beautiful, new way of looking at the sun. The original frames...

The buzzing sound that power lines produce is caused by corona discharge. Corona discharge is an electrical discharge that occurs when a fluid (like air) surrounding an electrically-charged conductor becomes ionized. In simple terms,...

Scientists from Durham University in the United Kingdom and NASA now propose that a universal mechanism can explain the whole spectrum of solar eruptions. They used 3-D computer simulations to demonstrate that a variety of eruptions...

A new study using observations from NASA's Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence that the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This...

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.

Armed with state-of-the-art supercomputer models, scientists have shown that colliding neutron stars can produce the energetic jet required for a gamma-ray burst. Earlier simulations demonstrated that mergers could make black holes....

This nugget explains the concept of radioactivity, its types and mathematical expressions and examples.

The number of sunspots increases and decreases over time in a regular, approximately 11-year cycle, called the sunspot cycle. The exact length of the cycle can vary. It has been as short as eight years and as long as fourteen, but the...

This nugget explains mathematically how the net magnetic flux through any closed surface is zero.

Seawater is an electrical conductor, and therefore interacts with Earths magnetic field. As the tides cycle around the ocean basins, the ocean water essentially tries to pull the geomagnetic field lines along. Because the salty water is...
