Boyang Liu was waiting with an 11-inch telescope and used it to photograph the orbiting outpost: "Looking through the eyepiece, I could almost feel it in 3D," says Liu. A still frame from the video shows wide solar arrays, a robotic arm, a science lab, a crew module, and two spacecraft (Tianzhou 4 and Shenzhou 14) waiting at docking ports--almost all added within the past year. The International Space Station is still much larger, but China is catching up. The growing station is now about as bright as a 1st magnitude star when it flies overhead in the night sky. To see it, visit Heavens Above and select Tiangong for local flyby predictions.

On July 27th, Donato Lioce of Valensole, France. photographed one leaping all the way over the Pleiades: "An incredible thunderstorm was underway when I took the picture," says Lioce. "With one camera I captured a red sprite just above the Pleiades star cluster. With a second camera, equipped with a longer lens, I caught a close-up view of the very same sprite (inset). It was super lucky!" "The picture has been taken close to the French village of Valensole," says Lioce, "but actually the storm and the sprite were over Italy more than 200 km away." It turns out, that is the perfect distance for catching sprites.

Automated software maintained by NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics. Daily results are presented here on Spaceweather.com. On Aug 02, 2022, the network reported 54 fireballs. (37 sporadics, 11 Perseids, 6 southern Delta Aquarids) In this diagram of the inner solar system, all of the fireball orbits intersect at a single point--Earth. The orbits are color-coded by velocity, from slow (red) to fast (blue). [Larger image] [movies] Potentially Hazardous Asteroids ( PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time. On August 2, 2022 there were 2291 potentially hazardous asteroids. | Recent & Upcoming Earth-asteroid encounters: Asteroid | Date(UT) | Miss Distance | Velocity (km/s) | Diameter (m) | 2022 OB2 | 2022-Jul-28 | 10.1 LD | 8.4 | 12 | 2022 NU1 | 2022-Jul-29 | 12.3 LD | 8.3 | 46 | 2022 OG1 | 2022-Jul-29 | 4.6 LD | 5 | 12 | 2016 CZ31 | 2022-Jul-29 | 7.3 LD | 15.5 | 138 | 2022 OE4 | 2022-Jul-30 | 5.3 LD | 4 | 6 | 531944 | 2022-Jul-30 | 18.2 LD | 5.9 | 173 | 2022 OD3 | 2022-Jul-31 | 19.6 LD | 6.9 | 18 | 2022 OU2 | 2022-Aug-01 | 3.6 LD | 8.4 | 38 | 2022 OW3 | 2022-Aug-01 | 5 LD | 8.3 | 18 | 2020 PP1 | 2022-Aug-01 | 13.1 LD | 3.7 | 17 | 2022 OJ5 | 2022-Aug-01 | 1.1 LD | 9.4 | 6 | 2022 OX3 | 2022-Aug-02 | 7.1 LD | 15.9 | 30 | 2022 OK5 | 2022-Aug-02 | 8.9 LD | 18 | 80 | 2022 PA | 2022-Aug-03 | 3.3 LD | 24.9 | 23 | 2020 PN1 | 2022-Aug-03 | 9.7 LD | 4.6 | 29 | 2022 OE2 | 2022-Aug-04 | 13.5 LD | 32.2 | 224 | 2022 OC3 | 2022-Aug-04 | 3.2 LD | 3.8 | 7 | 2022 OJ3 | 2022-Aug-04 | 5 LD | 12.5 | 39 | 2022 OB5 | 2022-Aug-05 | 2.7 LD | 2.1 | 6 | 2022 OH2 | 2022-Aug-07 | 4.4 LD | 4 | 12 | 2022 OC4 | 2022-Aug-09 | 4 LD | 7.5 | 11 | 2015 FF | 2022-Aug-12 | 11.2 LD | 9.2 | 17 | 2022 OT1 | 2022-Aug-13 | 12.4 LD | 5.8 | 36 | 2022 OA4 | 2022-Aug-14 | 18.2 LD | 7.9 | 23 | 2019 AV13 | 2022-Aug-22 | 19.1 LD | 8.8 | 135 | 2020 QW3 | 2022-Aug-22 | 14.1 LD | 18.1 | 30 | 2015 QH3 | 2022-Aug-22 | 5.6 LD | 7 | 14 | 2017 BU | 2022-Aug-29 | 15.8 LD | 7 | 32 | 2021 CQ5 | 2022-Sep-01 | 8.7 LD | 13.5 | 7 | 2020 PT4 | 2022-Sep-15 | 19.7 LD | 10.8 | 39 | 2016 HF2 | 2022-Sep-29 | 19.2 LD | 5.6 | 21 | Notes: LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU.

These balloons are equipped with sensors that detect secondary cosmic rays, a form of radiation from space that can penetrate all the way down to Earth's surface. Our monitoring program has been underway without interruption for 7 years, resulting in a unique dataset of in situ atmospheric measurements. Latest results (July 2022): Atmospheric radiation is decreasing in 2022. Our latest measurements in July 2022 registered a 6-year low: What's going on? Ironically, the radiation drop is caused by increasing solar activity. Solar Cycle 25 has roared to life faster than forecasters expected. The sun's strengthening and increasingly tangled magnetic field repels cosmic rays from deep space. In addition, solar coronal mass ejections (CMEs) sweep aside cosmic rays, causing sharp reductions called "Forbush Decreases." The two effects blend together to bring daily radiation levels down. .Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. They can alter the chemistry of the atmosphere, trigger lightning, and penetrate commercial airplanes. According to a study from the Harvard T.H. Chan school of public health, crews of aircraft have higher rates of cancer than the general population. The researchers listed cosmic rays, irregular sleep habits, and chemical contaminants as leading risk factors. A number of controversial studies (#1, #2, #3, #4) go even further, linking cosmic rays with cardiac arrhythmias and sudden cardiac death. Technical notes: The radiation sensors onboard our helium balloons detect X-rays and gamma-rays in the energy range 10 keV to 20 MeV. These energies span the range of medical X-ray machines and airport security scanners. Data points in the graph labeled "Stratospheric Radiation" correspond to the peak of the Regener-Pfotzer maximum, which lies about 67,000 feet above central California. When cosmic rays crash into Earth's atmosphere, they produce a spray of secondary particles that is most intense at the entrance to the stratosphere. Physicists Eric Regener and Georg Pfotzer discovered the maximum using balloons in the 1930s and it is what we are measuring today. | The official U.S. government space weather bureau | | The first place to look for information about sundogs, pillars, rainbows and related phenomena. | | Researchers call it a "Hubble for the sun."
