The students of Earth to Sky Calculus are selling space pendants to support their cosmic ray ballooning program. The sterling silver pendant touched space on April 29, 2023, when it hitched a ride onboard an Earth to Sky Calculus cosmic ray research balloon. SATURN'S CAT PENDANT: It's a far-out gift for the cat-lover in your life: Saturn's Cat. Note to mission planners: Don't forget space weather. ![]() This has made sightings of bright "Starlink trains" like Fetter recorded increasingly commonplace.Īdding together future launches proposed by SpaceX and other companies, some researchers estimate as many as 100,000 new satellites could be orbiting Earth by the end of the decade. The entire constellation has been launched since 2019, more than doubling the number of active satellites in Earth orbit. This launch brings the total count of Starlinks in orbit to 4127, a number that would have seemed incredible less than 5 years ago. Twenty-one hours later Kevin Fetter watched all 56 satellites orbit over his home in Brockville, Ontario: Solar flare alerts: SMS Text.ĥ6 MORE STARLINK SATELLITES: SpaceX launched a new batch of Starlink broadband satellites early Sunday morning, May 14th, and landed a rocket at sea in the company's latest successful mission. To illustrate the potency of these structures, the severe geomagnetic storm of April 23-24, 2023, was caused by a filament eruption, not a sunspot. Sometimes the debris falls back to the surface of the sun, triggering a Hyder Flare two explosions for the price of one. Their eruptions can hurl massive CMEs into space. This means there are about three times more filaments than sunspot groups, with half-a-dozen directly facing Earth.įamously unstable, solar filaments are twisted tubes of magnetism filled with dense plasma. This photo from Michael Borman of Evansville, Indiana, shows at least 20 dark filaments scattered around the solar disk: Unstable magnetic filaments pose a greater threat. SOLAR FILAMENTS OUTNUMBER SUNSPOTS: If there is an explosion on the sun today, it might not come from a sunspot. No more than minor G1-class geomagnetic storms are expected. Relatively faint and slow-moving, it was hurled into space on May 12th by an erupting filament of magnetism in the sun's southern hemisphere. MINOR CME IMPACT STILL POSSIBLE TODAY: NOAA forecasters say that a CME could hit Earth's magnetic field midday (UT) on May 16th. ![]() 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. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is intensifying, and this is reflected in the number of cosmic rays entering Earth's atmosphere. So there are kinda more net OUTSIDE force i.e atmosphere pressure plus tension of balloon on itself, so to balance this net force the INNER pressure has to be high comparative to "Alone" atmospheric pressure.Sunspot AR3305 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares. ![]() just an example u r squeezing balloon with your hand, I know it is very rough example still helpful! And yah remember the tension of balloon skin is on balloon itself not on the air inside ( this was my misconception that tension of balloon wall is applied on air inside). It will not decrease upto atmospheric pressure but a little higher ,Why?!!īecause I am neglecting something, as balloon is expanding it is gaining an elastic potential or tension along with a little bit decrease in inner pressure ( as area increase pressure decrease ) so elastic potential is like a. Suppose a normal balloon, now you blow it what actuallyyou are doing is creating high pressure in balloon so maintain an equilibrium balloon expands, Now pressure is decreasing but. But what i think as an answer is the pressure inside balloon is higher because not the atmosphere pressure is same as pressurein balloon, but because effective force is same.
