The frequency and scale of wildfires increases due to the rising temperatures and frequent draughts. Wildfires are part of the vicious cycle of climate change. Those “zombie fires” have reawaken in the approaching spring despite freezing temperatures as low as minus 60 degrees Fahrenheit (minus 50 degrees Celsius). Many of the current fires probably started in 2020 and survived the winter smouldering in the peats. Since the beginning of 2021, more than 400 forest fires have been reported with the regions of Tyumen, Omsk and Novosibirsk especially badly affected, according to the Russian Federal Forestry Agency. Siberia has been plagued with wildfires for several years. Wednesday, May 12, 2021: The European Sentinel 2 satellite captured a fire cloud generated by a blazing wildfire near the town of Oymyakon in north-eastern Siberia, close to the Arctic circle, on May 2. Tereza Pultarova Sun sets above Jezero Crater Juno originally observed the spot in June 2020, only two weeks after Foster’s discovery. Twice as wide and three times as long as the original spot, the evolved feature might persist for an extended period of time, the scientists believe. The images, captured by the JunoCam camera, reveal that the remnants of Clyde’s Spot had drifted away from the Great Red Spot and developed into a complex structure that scientists call a folded filamentary region. Juno flew over the area during its 33rd close pass on April 15 at a distance of about 16,800 miles (27,000 kilometers) from the top cloud layer. Named after its discoverer, retired engineer and avid sky-watcher Clyde Foster, the plume of cloud erupting above the gas giant’s atmosphere southeast of the famous Great Red Spot, has undergone substantial changes since its discovery in May last year. Thursday, May 20, 2021: NASA’s Juno mission captured images of Clyde’s Spot, a new feature in the atmosphere of Jupiter, first observed last year by an amateur astronomer in South Africa. Goldstone also collaborated with the 100-meter (330-foot) Green Bank Telescope in West Virginia to enable imaging of Apophis.(Image credit: NASA/JPL-Caltech/SwRI/MSSS/Kevin M Gill) The data for the study was gathered from the 70-meter (230-foot) radio antenna at the Deep Space Network’s Goldstone Deep Space Communications Complex near Barstow, California.

With the recent findings, the Risk Table no longer includes Apophis.

This greatly improved knowledge of its position in 2029 provides more certainty of its future motion, so we can now remove Apophis from the risk list.”įor this study, Farnocchia referred Sentry Impact Risk Table that continually scans the most current asteroid catalog for possibilities of future impact with Earth. With the support of recent optical observations and additional radar observations, the uncertainty in Apophis’ orbit has collapsed from hundreds of kilometers to just a handful of kilometers when projected to 2029. Davide Farnocchia of NASA’s Center for Near-Earth Object Studies (CNEOS), which is managed by NASA’s Jet Propulsion Laboratory in Southern California, said, “A 2068 impact is not in the realm of possibility anymore, and our calculations don’t show any impact risk for at least the next 100 years.
