Since Voyager 2 flew past the moon in 1979, evidence has mounted that Europa's icy surface overlies an enormous saltwater ocean-twice the volume of Earth's oceans combined. Juno couldn't actually see life in Europa's oceans, but the flyby could help NASA decide where future missions should look.Ībove: An example of chaos terrain on Europa, photographed by NASA's Galileo spacecraft in the late 1990s.Įuropa is one of the most interesting places in the solar system. EDT, Juno came within 222 miles of Europa's icy surface, taking pictures with a resolution of only 0.6 miles per pixel. JUNO JUST BUZZED EUROPA: NASA's Juno spacecraft just made the closest flyby of Jupiter's moon Europa in more than 20 years. Each one comes with a greeting card showing the bird and red lily in flight, and telling the story of their trip to the stratosphere and back again.Īll sales support hands-on STEM education The students are selling hummingbird pendants to pay the helium bill for their cosmic ray ballooning program. 22, 2022, the students of Earth to Sky Calculus launched the sterling silver pendant to the stratosphere onboard a cosmic ray research balloon, more than 117,710 feet high: STERLING SILVER HUMMINGBIRD PENDANT: This hummingbird has touched space. These regular, relatively long-term observations as the ejecta cloud expands and fades will paint a more complete picture of DART's aftermath. Hubble plans to monitor the Didymos-Dimorphos binary system 10 more times over the next three weeks. Some of the rays of ejecta appear to be curved, but astronomers need to take a closer look to confirm that the curvature is real and, if so, what it could mean.
The glow remained steady for more than eight hours after impact. In these visible-light images, the asteroid tripled in brightness after DART struck. 26th, almost every telescope in the Solar System was watching. HUBBLE IMAGES OF ASTEROID IMPACT: When NASA's DART spacecraft slammed into asteroid Dimorphos on Sept. More auroras in the USA were photographed by MaryBeth Kiczenski in Grand Portage, Minnesota by Mark Brown in Alburnett, Iowa from Josh Lopac in Wakefield, Michigan by Matthew Merrell in central Minnesota Although G2-class storms are merely moderate, not strong, they can produce mid-latitude auroras that are easy to catch using off-the-shelf digital cameras with night sky exposure settings. 1st: A nearby, grazing CME and some fast-moving solar wind. The circumstances were much the same as what NOAA is predicting for Oct. So we rushed to grab the camera, which to my surprise revealed auroras here at latitude 38 degrees." 27th when my little brother noticed something way up in the sky," says photographer Tyler Schlitt of Washington, MO. "I was out shooting deep space objects with my telescope on Sept. Auroras descended into the United States as far south as Missouri: 1st, it is worth reviewing what happened during the last G2-class storm. MID-LATITUDE AURORAS: With NOAA predicting a G2-class geomagnetic storm for Oct. (2) A CME will pass very close to Earth, potentially grazing our planet it left the sun on Sept. 1st in response to a double blow: (1) A solar wind stream is expected to hit Earth's magnetic field it is flowing from an equatorial hole in the sun's atmosphere. GEOMAGNETIC STORM WATCH (G2 CLASS): NOAA forecasters say that G2-class geomagnetic storms are possible on Oct. 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.
