2/11/17: NASA's Solar Dynamics Observatory: Year 7 Ultra HD (4k). The Solar Dynamics Observatory (SDO) has now captured nearly seven years worth of ultra-high resolution solar footage. This time lapse shows that full run from two of SDO's instruments. Credit: NASA's Goddard Space Flight Center/Scott Wiessinger.
2/10/17: Astronomers Estimate That The Solar Nebula Lasted 3 To 4 Million Years. By studying the remanent magnetizations in ancient meteorites, astronomers have determined that the solar nebula — the vast of disc of gas and dust that ultimately gave rise to the solar system — lasted around 3 to 4 million years.
2/7/17: What happened to the sun over 7,000 years ago? Analysis of tree rings reveals highly abnormal solar activity in the mid-Holocene. By analyzing the level of a carbon isotope in tree rings from a specimen of an ancient bristlecone pine, researchers have revealed that the sun exhibited a unique pattern of activity in 5480 BC. By comparing this event with other similar but more recent phenomena, they reported that this event may have involved a change in the sun's magnetic activity, or a number of successive solar burst emissions.
2/6/17: Fermi Sees Gamma Rays from Far Side Solar Flares. NASA's Fermi Gamma-ray Space Telescope has observed high-energy light from solar eruptions located on the far side of the sun. This apparent paradox is providing solar scientists with a unique tool for exploring how charged particles are accelerated to nearly the speed of light and move across the sun during solar flares.
2/3/17: NOAA's GOES-16 EXIS Instrument Observes Solar Flares. On January 21, 2017, the GOES-16 Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) observed solar flares. EXIS measures solar flares at several wavelengths and improves upon current capabilities by capturing larger flares, measuring the location of the flares on the sun, and measuring flares in more wavelengths.1/29/17: A Space Weather Report: Preparing Space Explorers for Bad Weather throughout the Solar System. C. Alex Young discusses the challenges of dealing with the harshness of space and making sure travelers can safely reach their destination as they reach for the planets and beyond. [75 min. webcast]
1/26/17: New Space Weather Model Helps Simulate Magnetic Structure of Solar Storms. The magnetic field of solar eruptions such as CMEs are difficult to predict and can interact with Earth’s magnetic fields, causing space weather effects. Built to simulate solar storms, a new tool called EEGGL-Eruptive Event Generator (Gibson and Low)- helps NASA study how a CME might travel through space to Earth and what magnetic configuration it will have when it arrives.
1/17/17:ALMA Starts Observing the Sun New images taken with the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile have revealed otherwise invisible details of our Sun, including a new view of the dark, contorted centre of a sunspot that is nearly twice the diameter of the Earth. The images are the first ever made of the Sun with a facility where European Southern Observatory is a partner. The results are an important expansion of the range of observations that can be used to probe the physics of our nearest star.
1/6/17: NASA Study Finds Solar Storms Could Spark Soils at Moon's Poles. Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce "sparks" that could vaporize and melt the soil, perhaps as much as meteoroid impacts, according to NASA-funded research.
11/6/16: PPPL physicists find clue to formation of magnetic fields around stars and galaxies. An enduring astronomical mystery is how stars and galaxies acquire their magnetic fields. Physicists have now found a clue to the answer in the collective behavior of small magnetic disturbances.
11/14/16: NASA finds unusual origins of high-energy electrons. High above the surface, Earth's magnetic field constantly deflects incoming supersonic particles from the sun. These particles are disturbed in regions just outside of Earth's magnetic field - and some are reflected into a turbulent region called the foreshock. New observations from NASA's THEMIS mission show that this turbulent region can accelerate electrons up to speeds approaching the speed of light.
10/10/16: Researchers discover effect of rare solar wind on Earth's radiation belts. Researchers from the University of New Hampshire have captured unique measurements of the Van Allen radiation belts, which circle the Earth, during an extremely rare solar wind event. The findings, which have never been reported before, may be helpful in protecting orbiting telecommunication and navigational satellites, and possibly future astronauts, by helping to more accurately predict space conditions near Earth, as well as around more remote planets.

9/23/16: NASA-Funded Sounding Rocket Solves One Cosmic Mystery, Reveals Another. In the last century, humans realized that space is filled with types of light we can’t see – from infrared signals released by hot stars and galaxies, to the cosmic microwave background that comes from every corner of the universe. Some of this invisible light that fills space takes the form of X-rays, the source of which has been hotly contended over the past few decades.
9/19/16: The Dynamic Duo: RAVE complements Gaia. The new data release of the RAdial Velocity Experiment (RAVE) is the fifth spectroscopic release of a survey of stars in the southern celestial hemisphere. It contains radial velocities for 520,781 spectra of 457,588 unique stars that were observed over ten years.
9/14/16:Hinode: 10th Anniversary of Its Launch. The solar observing satellite “Hinode” will celebrate the 10th anniversary of its launch on 23 September (Japan standard time). This 3-minutes movie presents the solar atmosphere fulfilled with active phenomena much more than ever imagined, captured with the Hinode telescopes.
9/1/16: Images From Sun’s Edge Reveal Origins of Solar Wind. Ever since the 1950s discovery of the solar wind -- the constant flow of charged particles from the Sun -- there's been a stark disconnect between this outpouring and the sun itself. The details of the transition from defined rays in the corona, the sun's upper atmosphere, to the solar wind have been, until now, a mystery.
