It turns out that you don’t need the Men in Black to spot unidentified anomalous phenomena, which are also known as UAPs, unidentified flying objects or UFOs. Researchers have shown how the task of detecting aerial objects in motion could be done by analyzing Earth imagery from commercial satellites. They say they demonstrated the technique using one of the most notorious UAP incidents of recent times: last year’s flight of a Chinese spy balloon over the U.S. , which ended in a shootdown by an Air Force fighter jet above the Atlantic Ocean. They also analyzed imagery of a different spy balloon that passed over Colombia at about the same time. “Our proposed method appears to be successful and allows the measurement of the apparent velocity of moving objects,” the researchers report. In a 2023 video, CBS News recaps lessons learned from the Chinese spy balloon’s flight: The demonstration is described in a research paper written by Harvard University’s Eric Keto and Wellesley Co
Earth releases about as much energy out into space as it absorbs, arriving at a thermal equilibrium. This means it will reach an average temperature as is the case with most planets. Saturn however, is a little different as recent observations show the planet’s energy is out of balance. It seems that in addition to the energy it receives from the Sun, there must also be an internal source of heat, perhaps driven by its highly elliptical orbit. Saturn is the sixth planet from the Sun and is most well known for its stunning ring system. It was the first celestial object I saw through a telescope and like many others, captured my imagination. Of all the planets Jupiter is the largest followed by Saturn which has an equatorial diameter (not including the rings) of 116,460 kilometres. The Cassini spacecraft began its journey to Saturn in 1997. After a seven year journey it arrived in 2004 and until 2017 studied the ringed planet. It carried an array of scientific instruments including
