8, 2022, the second planet was at inferior conjunction with the sun. Why is it a crescent? Because Venus itself was a crescent on the date of the flight. It comes with a greeting card showing the pendant in flight and telling the story of its journey to the stratosphere. The opal crescent is framed by sterling silver with a matching hypoallergenic chain. This one flew to the stratosphere onboard a cosmic ray research balloon on Jan. THE CRESCENT VENUS PENDANT: Are you looking for a far-out gift? Nothing says "I love you" like a Venus Pendant from the edge of space. The spring season for blue jets is only weeks away. Blue jets also produce NOx and ozone, potentially affecting the chemistry of the upper atmosphere.īlue jets are still poorly understood and only sparsely documented. This is high enough to touch the ionosphere, possibly forming a new and poorly understood branch of Earth's global electrical circuit. Photos taken from the International Space Station (ISS) show that blue jets reach astonishing altitudes, as high as 170,000 feet. You could touch one with your hand and it might not hurt. Blue jets are made of cold plasma akin to gas inside a flourescent light bulb. Normal lightning carves a scorching-hot path through the atmosphere, heating the air to 30,000 degrees Celsius. Storm chaser " Pecos Hank" has just made a video re-visiting the event:īlue jets might look like lightning, but they are not the same. RE-VISITING A BLUE JET: Last July 28th, photographers in Texas witnessed a remarkable blue jet emerging from the top of a huge thunderstorm. Readers with solar telescopes are encouraged to monitor developments. Some research suggests that magnetic fields at the base of a light bridge are busy cross-crossing and reconnecting-the same explosive process that sparks solar flares.ĭoes this mean sunspot AR3245 will explode-or quietly fall apart? No one can say. They often herald the break-up of a sunspot, with jets of plasma shooting up from the chasm as the sunspot decays. The nature of light bridges is not fully understood. The bright, linear gap between the sunspot's two halves is known as a " light bridge." It measures 20,000 km from end to end. This 24-hour movie from NASA's Solar Dynamics Observatory shows the sunspot's primary core dividing like a eukaryotic cell as it turns toward Earth: SUNSPOT MITOSIS : Sunspot AR3245 is splitting in two. Now for the good news: It's almost spring! And auroras love equinoxes. Proofreading is appreciated-but please report the errors in a respectful way, mindful of the fact that we're stretched thin, working in the middle of a disaster zone. You're going to see more typos than usual. This winter's record-setting snowfall, avalanches, and frequent evacuations are impacting the production of the web site. Tony Phillips from a location in the Sierra Nevada mountains at 8500 ft elevation. 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.Ī NOTE TO READERS : is written by Dr. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is intensifying, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Sunspot AR3245 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares.
