While it seems static from our vantage point on Earth 93 million miles away, the sun is constantly changing. Under the influence of complex magnetic forces, material moves throughout the solar atmosphere and can burst forth in massive eruptions. NASA’s Interface Region Imaging Spectrograph, or IRIS, which will continue its… Read more“NASA’s Sun-Observing IRIS Mission”

Was Pluto’s frozen heart formed in an ancient impact basin and was it once closer to the north pole? And does the icy heart conceal a subsurface ocean? This high-resolution image captured by NASA’s New Horizons spacecraft shows the bright expanse of the western lobe of Pluto’s “heart,” or Sputnik… Read more“Scientists Probe Mystery of Pluto’s Icy Heart”

Saturn and Mimas Saturn’s icy moon Mimas is dwarfed by the planet’s enormous rings. Because Mimas (near lower left) appears tiny by comparison, it might seem that the rings would be far more massive, but this is not the case. Scientists think the rings are no more than a few… Read more“Tiny Mimas, Huge Rings”

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 –… Read more“NASA’s SDO Witnesses a Double Eclipse”
