NASA Goddard: Snapshots from the Edge of the Sun

For the first time, using NASA’s Solar Terrestrial Relations Observatory, or STEREO, scientists have imaged the edge of the sun and described that transition – from which the solar wind blows. Defining the details of this boundary helps us learn more about our solar neighborhood, which is bathed throughout by solar material – a space …

NASA Goddard: NASA’s SDO Captures Mercury Transit Time-lapse

Around 13 times per century, Mercury passes between Earth and the sun in a rare astronomical event known as a planetary transit. The 2016 Mercury transit occurred on May 9, between roughly 7:12 a.m. and 2:42 p.m. EDT.

NASA’s 4K View of April 17 Solar Flare

On April 17, 2016, an active region on the sun’s right side released a mid-level solar flare, captured here by NASA’s Solar Dynamics Observatory. This solar flare caused moderate radio blackouts, according to NOAA’s Space Weather Prediction Center. Scientists study active regions – which are areas of intense magnetism – to better understand why they …

NASA Goddard: Solar Dynamics Observatory: Year 6 Ultra-HD

The sun is always changing and NASA’s Solar Dynamics Observatory is always watching. Launched on Feb. 11, 2010, SDO keeps a 24-hour eye on the entire disk of the sun, with a prime view of the graceful dance of solar material coursing through the sun’s atmosphere, the corona. SDO’s sixth year in orbit was no …

NASA Goddard: Understanding the Magnetic Sun

NASA GSFC solar scientist Holly Gilbert explains a computer model of the sun’s magnetic field. Grasping what drives that magnetic system is crucial for understanding the nature of space throughout the solar system: The sun’s invisible magnetic field is responsible for everything from the solar explosions that cause space weather on Earth – such as …

NASA: Highlights from SOHO’s 20 Years in Space

Dr. Joe Gurman of NASA’s Goddard Space Flight Center provides commentary on selected shots from SOHO’s 20 years in space. After 20 years in space, ESA and NASA’s Solar and Heliospheric Observatory, or SOHO, is still going strong. Originally launched in 1995 to study the sun and its influence out to the very edges of …

NASA | Thermonuclear Art – The Sun In Ultra-HD (4K)

It’s always shining, always ablaze with light and energy. In the ubiquity of solar output, Earth swims in an endless tide of particles. Every time half of the Earth faces the Sun, we experience the brightness of daytime, the Sun’s energy and light driving weather, biology and more. But in space, NASA’s Solar Dynamics Observatory …

Michael König: SUN

Edited time lapse sequences of the sun’s atmosphere observed by the Solar Dynamics Observatory spacecraft between 2011 and 2015.  

NASA: SDO | Year 5

February 11, 2015 marks five years in space for NASA’s Solar Dynamics Observatory, which provides incredibly detailed images of the whole sun 24 hours a day. Capturing an image more than once per second, SDO has provided an unprecedentedly clear picture of how massive explosions on the sun grow and erupt ever since its launch …

NOAA: Deep Space Climate Observatory Satellite

The Deep Space Climate Observatory satellite mission, better known as DSCOVR, will monitor the constant stream of charged particles from the sun, also called “Solar Winds.” These observations are the backbone of NOAA space weather alerts and forecasts. The DSCOVR is on track for launch in early 2015.  

NASA: September 10, 2014 X1.6 flare

The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT on Sept. 10, 2014. NASA’s Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. However — when intense enough — …

Nicholas Buer: Ancients

This film follows the ancient cycle of sunset, to night, to sunrise. A continuous loop of perpetual movement that has been unbroken since the dawn of time, and the only true constant in our lives.  

NASA EDGE: MMS One Step Closer to Launch

Published on Mar 26, 2014 NASA EDGE talks with the Magnetospheric Multiscale Mission Team about the final tests for the satellites before they head to NASA Kennedy. Guests include Joanne Baker, Rommel Zara, Troy Cline and Deirdre Wendel.  

Beakus: How Do We Know How Old The Sun Is?

In ‘How Do We Know How Old The Sun Is?’ ROG astronomer Brendan explains how we determine the age of our Solar System from space rocks and how we can work out how long the Sun has left before it engulfs the inner planets.  

NASA: Canyon of Fire on the Sun

A magnetic filament of solar material erupted on the sun in late September, breaking the quiet conditions in a spectacular fashion. The 200,000 mile long filament ripped through the sun’s atmosphere, the corona, leaving behind what looks like a canyon of fire. The glowing canyon traces the channel where magnetic fields held the filament aloft …

NASA: NASA’s latest view of the Sun

IRIS is a NASA Small Explorer Mission to observe how solar material moves in a dynamic million-degree atmosphere that drives the solar wind around the Sun’s atmosphere. It joins a fleet of spacecraft currently studying the Sun.

NASA: Magnificent Sun Eruption

Last month our sun had a coronal mass ejection that traveled away from the sun at over 1450 kilometers per second (900 miles per second). The video below show this massive eruption, as captured by NASA’s Solar Dynamics Observatory (SDO), NASA’s Solar Terrestrial Relations Observatory (STEREO), and the joint ESA/NASA Solar Heliospheric Observatory (SOHO).

The Venus Transit

As seen by the SDO, The NASA Solar Dynamics Observatory. The SDO is a sun-pointing semi-autonomous spacecraft that will allow nearly continuous observations of the Sun with a continuous science data downlink The next time Venus will pass by the Sun is about a 100 years from now. _________________ http://sdo.gsfc.nasa.gov/ __________________________________
