Matt Lemke, Orion avionics, power and software deputy manager, discusses how Orion is radiation-hardened so the systems inside can withstand the harsh environment of space. HWHAP Episode 75.

A massive storm over the Sun discharged the largest solar flare in three years on Sunday, No. 29. <br/>

NASA Chief Scientist Jim Green sits down with solar scientist Alex Young to discuss the Sun’s powerful explosions.

The sun has emitted a huge solar flare that is heading towards earth, NASA has warned. The eruption of the X-flare, the strongest kind, occurred at 0156 GMT on Tuesday and was recorded by the US space agency's Solar Dynamics Observatory....

Yaireska Collado-Vega leads a team at NASA’s Goddard Spacecraft Center that is studying the solar weather environment so that robots and people exploring space can be protected. In this episode of Gravity Assist, she describes the...

A solar flare hit Earth’s atmosphere, creating a geomagnetic storm at the worst possible moment.

Humans haven't been to Mars yet, and there's a good reason for that - it's really not good for the your body! In this episode, Dom finds himself stranded in space with only 12 minutes of oxygen left to find out why. Accompanied by the...

Even though our Sun shines bright in the sky, it is shrouded in mystery. In this episode, we'll sit down with scientists working to get us closer to the Sun than ever before.

An international science team says NASA's Fermi Gamma-ray Space Telescope has observed high-energy light from solar eruptions located on the far side of the sun, which should block direct light from these events. This...

During a powerful solar blast in March, NASA's Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun. The discovery heralds Fermi's new role as a solar observatory,...

Flares happen when the powerful magnetic fields in and around the sun reconnect. They're usually associated with active regions, often seen as sun spots, where the magnetic fields are strongest. Flares are classified according to...

Dr. Stan Love, NASA astronaut and all-around smart guy, flew to the International Space Station in 2008 and has worked on a number of flight analog programs to understand how to conduct deep-space missions. Love explores the challenges...

August 1972, as NASA scientist Ian Richardson remembers it, was hot. In Surrey, England, where he grew up, the fields were brown and dry, and people tried to stay out of the Sun, indoors and televisions on. But for several...

The Solar Dynamics Observatory, or SDO, spacecraft was launched on Feb. 11, 2010, and began collecting science data a few months later. With two imaging instruments – the Atmospheric Imaging Assembly and the Helioseismic and...

Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection.



Magnetic reconnection happens when magnetic field lines...

NASA's STEREO spacecraft and new data processing techniques have succeeded in tracking space weather events from their origin in the Sun's ultrahot corona to impact with the Earth 96 million miles away, resolving a 40-year...

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

On Jan. 28, 2014, NASA's Interface Region Imaging Spectrograph, or IRIS, witnessed its strongest solar flare since it launched in the summer of 2013. Solar flares are bursts of x-rays and light that stream out into space, but...

On March 29, 2014 the sun released an X-class flare. It was observed by NASA's Interface Region Imaging Spectrograph, or IRIS; NASA's Solar Dynamics Observatory, or SDO; NASA's Reuven Ramaty High Energy Solar Spectroscopic Imager,...

We are all familiar with weather on Earth, but how much do you know about weather in space? Suitable for all ages, this introduction to space weather covers vocabulary like coronal mass ejection (CME), solar wind, and solar flare....

Launched ten years ago, on Oct. 25, 2006, the twin spacecraft of NASA’s STEREO mission – short for Solar and Terrestrial Relations Observatory – have given us unprecedented views of the sun, including the first-ever...
