Seven years of Solar Dynamics

2 weeks agoNews : Slugger O'Toole

It seems like only yesterday that I was noting First Light on Nasa’s Solar Dynamics Observatory [SDO], and the early hours of this morning for ‘three years in three minutes‘ and ‘SDO Year 4‘.  In fact the SDO was launched on 11 Feb 2010, with First Light in April of that year. [Seven long years… more...

New space weather model helps simulate magnetic structure of solar storms

The dynamic space environment that surrounds Earth - the space our astronauts and spacecraft travel through - can be rattled by huge solar eruptions from the sun, which spew giant clouds of magnetic energy and plasma, a hot gas of electrically charged particles, out into space. Show More Summary

Solar At The Beginning Of 2016 Vs Solar At The End Of 2016

Sometimes solar energy seems to be on a tear. Then suddenly the industry is on the verge of collapse. This dynamic is known as the Solarcoaster. While 2016 was a wild ride for all of us, the volatility was more pronounced in renewables than in most sectors.

NASA Solar Dynamics Observatory --Earth is Putting the "Brakes" On Sun's Rotation

Astronomers from the University of Hawaii Institute for Astronomy (IfA), Brazil, and Stanford University may have solved a long-standing solar mystery. Two decades ago, scientists discovered that the outer five percent of the sun spins more slowly than the rest...        

NASA just spotted a massive hole growing on the surface of the sun — here’s what it means

NASA's Solar Dynamics Observatory just spotted a massive hole on the sun surface called a coronal hole. The hole appears black because it's cooler than its surroundings, and is responsible for high-speed solar winds that can sometimes...Show More Summary

Sculpting solar systems

(ESO) Sharp new observations have revealed striking features in planet-forming discs around young stars. The SPHERE instrument, mounted on ESO's Very Large Telescope, has made it possible to observe the complex dynamics of young solar systems. Show More Summary

Sculpting solar systems: SPHERE instrument reveals protoplanetary discs being shaped by newborn planets

Sharp new observations have revealed striking features in planet-forming discs around young stars. The SPHERE instrument, mounted on ESO's Very Large Telescope, has made it possible to observe the complex dynamics of young solar systems. Show More Summary

Image: NASA's SDO performs calibration maneuvers

On Oct. 19, 2016, operators instructed NASA's Solar Dynamics Observatory, or SDO, to look up and down and then side to side over the course of six hours, as if tracing a great plus sign in space. During this time, SDO produced some unusual data. Show More Summary

NASA's spacecraft catches stunning view of partial solar eclipse from space

NASA combined two pictures of the sun at different wavelengths of extreme ultraviolet light to create a spooky Halloween image.

Generation of Highly Inclined Trans-Neptunian Objects by Planet Nine

Generation of Highly Inclined Trans-Neptunian Objects by Planet Nine Authors: Batygin et al Abstract: The trans-Neptunian region of the solar system exhibits an intricate dynamical structure, much of which can be explained by an instability-driven orbital history of the giant planets.

Video: NASA's SDO watches magnetic arches tower over sun's surface

Massive arches of solar material brighten and stream over an active region on the sun's surface in this animation of imagery captured by NASA's Solar Dynamics Observatory, or SDO, on Sept. 29, 2016.

Can India Learn From Germany’s Solar Experience?

Over the past few years, as the German solar market has slowed to a steady, unsubsidized pace, India has emerged as one of the most dynamic new markets. It wants to build as much as 40 GW rooftop solar by 2022 and a total of 100 GW.Show More Summary

Watch a double eclipse of the sun as seen from outer space - CNET

6 months agoTechnology : CNET: News

It's eclipse season for the Solar Dynamics Observatory, and it's kicking off with both the Earth and the moon passing in front of the sun.

NASA's SDO witnesses a double eclipse

Early in the morning of Sept. 1, 2016, NASA's Solar Dynamics Observatory, or SDO, caught both Earth and the moon crossing in front of the sun. SDO keeps a constant eye on the sun, but during SDO's semiannual eclipse seasons, Earth briefly blocks SDO's line of sight each day -- a consequence of SDO's geosynchronous orbit.

NASA's Solar Observatory Freaked Out But Everything's OK Now

After more than a week offline, NASA’s Solar Dynamics Observatory — the sun-watching spacecraft responsible for these close-up images of solar flares, fire and loops — is back. But just what caused it to glitch in the first place? More »
