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. With three dark cores larger than Earth embedded in a vast field of bright magnetic froth, this sunspot complex is an easy target for backyard solar telescopes. There is an increasing chance of geoeffective eruptions as they turn toward Earth this weekend. "These large sunspots are seething with activity," saysTeodorescu, "although they haven't produced any strong flares yet." Emphasis on yet. Maximilian Teodorescu photographed them today from his backyard observatory in Magurele, Romania: Sunspots AR3105-3107 have rounded the sun's southeastern limb and now they are turning toward Earth. When it is completed in December 2023, Tiangong with be a Mir-class facility massing nearly 70 tons with living space for as many as 7 astronauts and even a Hubble-class telescope to view the cosmos.īIG SUNSPOT ALERT: They're coming. The ISS is still much larger, but China is catching up. With solar arrays, a robotic arm, multiple modules, and two spacecraft (Tianzhou 4 and Shenzhou 14) waiting at docking ports, Tiangong is starting to look a lot like the ISS. "I scaled all of these images so they show the spacecraft as they would appear side-by-side at the same distance from my telescope," notes Smith. Between the two is Tiangong as it appeared to Smith on Sept. On the right is a recent photo of the International Space Station. On the left is station's original core module, Tianhe-1, which Smith photographed in 2021. "I created this composite photo to show how much it has grown." 22nd, astrophotographer Philip Smith watched Tiangong fly over his backyard in New York. In the past year alone, it has more than doubled in size, and it is starting to rival its older cousin the International Space Station (ISS). Aurora alerts: SMS Text.ĬHINA'S GROWING SPACE STATION: China's Tiangong space station is in the big leagues now. 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.
