![]() The students are selling space pearls to support their cosmic ray ballooning program. For more than 2 hours it floated 101,378 feet above the Sierra Nevada mountains of central California: Last January, the students of Earth to Sky Calculus launched this unique pendant to the stratosphere onboard a cosmic ray research balloon. THE INFINITY PEARL: Nothing says "I love you forever" like the Infinity Pearl. Rather, this is Neptune’s large and unusual moon, Triton. Dominating this Webb portrait of Neptune is a very bright point of light radiating diffraction spikes seen in many of Webb's images, but this is not a star. Webb also captured seven of Neptune’s 14 known moons. They were likely created by the collisional fragmentation of onetime inner moons and are made of extremely dark organic compounds processed by radiation. The rings of Neptune, like those of Uranus, are thought to be relatively young their age is significantly less than that of the Solar System. Some of the rings have not been detected since NASA’s Voyager 2 became the first spacecraft to observe Neptune during its flyby in 1989. "It has been three decades since we last saw these faint, dusty rings, and this is the first time we’ve seen them in infrared light," notes Heidi Hammel, an interdisciplinary scientist for Webb. WEBB PHOTOGRAPHS NEPTUNE'S RINGS: The James Webb Space Telescope has just captured the clearest view of Neptune’s rings in more than 30 years. The chance of a geoeffective flare will increase in the days ahead as these sunspots enter the Earth strike zone. With three dark cores larger than Earth embedded in a vast field of bright magnetic froth, sunspot complex AR3105-3107 is an easy target for backyard solar telescopes. This movie from NASA's Solar Dynamics Observatory shows their progess in the past 24 hours: ![]() Aurora alerts: SMS Text.īIG SUNSPOT ALERT: A pair of large sunspots just emerged over the sun's southeastern limb, and they are turning toward Earth. High-latitude auroras are possible when the windy stream arrives. The gaseous material is flowing from an equatorial hole in the sun's atmosphere. 23rd when a high-speed stream of solar wind is expected to hit Earth's magnetic field. ![]() Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining-a result of the yin-yang relationship between the solar cycle and cosmic rays.ĬHANCE OF MINOR STORMS: NOAA forecasters say that a minor G1-class geomagnetic storm is possible on Sept. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is beginning, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Big sunspots AR3105 and AR3107 are turning toward Earth and might soon pose a threat for geoeffective solar flares. ![]()
